Opening Highlights


Vasily Ivanchuk Read Nikolay Kalinichenko’s new book on Ivanchuk and be amazed at the Ukrainian ace’s versatility. At the London Candidates’ he played the role of the joker, losing four games on time but still playing a crucial role by beating Carlsen and crushing Kramnik’s Pirc. And what did Aronian really achieve against his Budapest Gambit? The connoisseur, Viktor Moskalenko, enlightens you in the Forum Section on page 11.

He’ s the star pupil of Laszlo Hazai, who for decades has been forming a star Yearbook author team with Peter Lukacs. In the B-Group of Wijk aan Zee, which he nearly won, Rapport tried the pushy 6.c5 against top-seed Sergey Movsesian’s Chebanenko Slav. The latter reacted adroitly, but Rapport kept pushing and won brilliantly. His own notes on that game are in the Survey by Lukacs and Hazai on page 141.


Richard Rapport

The Dutch grandmaster wrote a highly acclaimed book called ‘The Strategic Nimzo-Indian’ last year. At Wijk aan Zee, Sokolov practiced what he had preached and caused Pentala Harikrishna some trouble. But three rounds later he ran into a nice refinement by Peter Leko and even lost. Sokolov will have to do some repair work on his beloved opening. The Survey on page 162 by that other expert, Viacheslav Ikonnikov, may help.

Alexander Ipatov The current under-20 World Champion is a true globetrotter and a flexible player. Who in the 2600 Elo region would reply 3...Àe4 to 3.Àe5 in the Petroff? It’s a great surprise weapon, though, in classical tournaments and even more so in blitz. And as our new contributor shows in his Survey on page 106, there’s more to this bizarre-looking Petroff line than meets the eye. Isn’t there always?



Ivan Sokolov


Anish Giri On Board 1 for Hoogeveen in the World Cities championship, Anish Giri had to beat Varuzhan Akobian with black in the final round. After some sharp preparation the Dutchman sacrificed two pawns in the 4.Ãg5 Grünfeld Indian for some fantastic piece play. On his pet opening, Giri wrote in his New In Chess report: ‘We are all human and get bad positions – unless we play the Grünfeld.’ Read Tibor Karolyi’s Survey on this entertaining line on page 188.

The young Swede has the looks of a lion – and also the fighting qualities. He wallows in sharp and unclear complications and loves to provoke. At Wijk aan Zee against Alexander Ipatov he tried out a very controversial line against the Rauzer. The move 6.Ãg5 is supposed to prevent 6…g6, so what does Grandelius play? Exactly. Jeroen Bosch investigates the deeper points of this ‘insult to the Rauzer' in his Survey on page 63.


Nils Grandelius

Sometimes you have feel a sacrifice must be good – and sometimes it even is! Dejan Antic had that feeling when he saw 13.Àf5 while preparing for fellow-Serbian grandmaster Markovic, not knowing it had already been played one week earlier. Antic presents this smashing novelty in the Classical King's Indian on page 194. Now Kasimdzhanov has also adopted it against Topalov, so King’s Indian players have work to do.

Luis Rodi Luis Rodi is an IM from Uruguay who currently lives in that city of cities, Rio de Janeiro. He likes aggressive chess, so in his first Yearbook Survey on page 75 he analyses a relatively unknown line devised by Dragoljub Velimirovic, who combated the Sicilian and the Pirc with the same bishop sortie. Why shouldn’t Ãc4 be good in the Austrian Attack as well? You may wonder yourself after reading this article.

A Spectacular Budapest Game by Viktor Moskalenko VO 17.2 (A52)

Aronian,Levon Ivanchuk,Vasily London ct 2013 (10)

YB 88

During the London Candidates’, Vasily Ivanchuk decided to play the controversial Budapest Gambit. This game was a curious and fortunate turn of fate for the entire chess world, who followed this exciting tournament, as well as for many fans of the Budapester. But this occurrence of the Gambit wasn’t a big surprise for me... since last year in October, when I met Vassily at Cap d’Agde (one of the greatest French chess events), he told me with some emotion that he had read my book The Fabulous Budapest Gambit – and admitted that he was highly impressed. Not only with the many ideas in the book, but with the decision to write such a book in the first place!

1.d4 Àf6 2.c4 e5!

When this move appeared on the tournament’s Internet display, I start to receive telephone calls and lots of Facebook messages during the following next hours and days – from the many Budapest Gambit fans all over the world. 3.de5 Àg4 4.Àf3 Àc6 5.Ãf4

Transposing to the Rubinstein Variation. 5...Ãb4 6.Àc3!?

In fact, Ivanchuk is the second ‘Budapest player’ in history at World Championship Candidates level. More than 20 years ago 6.Àbd2 ©e7 7.e3 was seen in the famous game Karpov-Short, Linares (Candidates sf1) 1992 (1-0 in 43). See Game 27 in my Fabulous Budapest Gambit book.


and particularly

Vasily Ivanchuk and Viktor Moskalenko


6...Ãc3 7.bc3 ©e7 8.©d5 f6 9.ef6 Àf6 10.©d3 d6 11.g3!

Once again, the black player found his opponent well-prepared. Armenian grandmaster Levon Aronian quickly played the most ambitious move in this line!

._._Tt.m jJj.d.jJ ._Sj.s._ _._._._. ._In.bL_ _.iQ_.i. I_._IiBi _._.rRk. 15...Àe5!

After 15...Àa5!? (Black prefers to keep the game complicated by avoiding exchanges) 16.Ãg5 ©e5 17.Ãf6 Õf6 Black also has compensation, Dlugy-Epishin, New York 1989 (Game 8, FBG). 16.Ãe5 de5 17.Àf5!?N


As happened several times with Ivanchuk in this tournament, he started spending too much time from the very early opening. Here, he may have recalled his own game of 14 years ago: 11...b6 12.Ãg2 Ãb7 13.0-0 Àa5 14.Àd4 Ãg2 15.®g2 0-0 16.Ãg5 Õae8 17.Õae1 ©f7 (17...©e4!?) 18.Ãf6 gf6 19.e4 ©c4 20.©d2 Àb7 21.Õe3 Àc5 22.Õfe1 a5 23.h4 a4 24.©e2 ©e2 25.Õ1e2 ®f7 ½-½ Ljubojevic-Ivanchuk, Monaco (blindfold) 1999. 12.Ãg2 Ãg4!?

‘The plan with ...Ãg4 and ...Õe8 is a good possibility to fight the 11.g3 fianchetto. All Black’s pieces are active and prepared to attack White’s weaknesses, the pawns on c3/c4, e2 and a2, and also the centre and the kingside (see Games 8 and 9)’ – The Fabulous Budapest Gambit. 13.0-0 Õae8 14.Õae1!? ®h8!

This move (played originally by the Budapest fighter of the 1990’s, GM Epishin) is very useful, as it prevents a possible check or a pin on the a2-g8 diagonal. 14...Ãh5!? is an alternative. 15.Àd4!?

The typical knight manoeuvre. Now Black has two ways to maintain a kind of balance: 12

The best move and a novelty by Aronian. In case of 17.Àb3 c5 White’s position is blocked; after 18.h3 the game J. PiketReinderman, Rotterdam ch-NED 1999, was agreed drawn. 17...Ãf5

Alternatively, 17...©f7!? 18.Àe3 e4 19.©d4 b6 20.c5 Ãe6¤ leads to a complicated game. 18.©f5 Àd7

Also possible was 18...e4 or 18...b6!?. 19.©e4 c6!?

As usual, Ivanchuk tries to play creatively, intending ...Àb6/©c5, to attack the weak pawn on c4. One of the oldest Budapest heroes, grandmaster Carl Schlechter (1874-1918), was the originator of the typical knight manoeuvre to e4 and c5 (in this case ...Àd7-c5).


White is seeking an attack, preparing Ãe4. 22...g6! 23.Ãe4 ®g7 24.®g2

Here, Aronian decided take advantage of Ivanchuk ‘clock syndrome’ and does something quite unexpected, changing a positional game into an attacking one – but this is mere fiction. 24...©c4 25.Õfd1 ©a2!

Black accepts the complications, but will soon make a decisive mistake and lose on time... 25...Õf7 was a safer option. 26.g4

._._Tt._ jJ_._.mJ .sJ_._J_ _._.j._. ._._B_Iq _.iR_._. D_._IiKi _._R_._. 26...Õf4

After the proper defence 26...©c4! 27.g5 ®h8 28.Õh3 Õe7 Black must be better, due to his pawn majority on the queenside. 27.Ãf5!?

Perhaps this Ivanchuk.



27...Àd5 28.Õh3 Õh8?

20.Õd1 Àb6 21.Õd3 ©c5=

The best defence was 28...h5! when White has nothing better than to accept a draw after 29.©g5 (29.e3 gf5=) 29...Õg4 30.Ãg4 hg4 31.©h6 ®f6 32.©h4 ®g7= etc.

Now the position is balanced.

29.e3 gf5? 30.ef4T


Black lost on time.

‘We see that the plan with ...Ãg4 and ...Õe8 successfully reduces the effect of the powerful knight move to d4. If Black remains alert, he will get enough counterplay to keep the balance: as always in this line, if White plays Àd4!?, Black replies ...Àe5!, after which he has the same number of pieces in the centre’ – FBG, Game 8.

An Interesting Knight Sac by B. Shankarasubbu CK 12.3 (B12/B15)

YB 105

Hello sirs, Last year my novelty in the Najdorf Sicilian was published in Yearbook 97. Now I have found a new move in the mainline Caro-Kann. 1.e4 c6 2.d4 d5 3.Àc3 de4 4.Àe4 Ãf5 5.Àg3 Ãg6 6.h4 h6 7.Àf3 Àd7 8.h5 Ãh7 9.Ãd3 Ãd3 10.©d3 e6 11.Ãd2 Àgf6 12.0-0-0 Ãe7 13.Àe4

T_.dM_.t jJ_SlJj. ._J_Js.j _._._._I ._.iN_._ _._Q_N_. IiIb.iI_ _.kR_._R In this position GM Lars Schandorff recommends 13...Àe4 in his nice repertoire book The Caro-Kann, published in 2010, because he feels that Black does not have a good defence after 13...0-0 14.g4 Àe4 15.©e4 Àf6 16.©e2 ©d5 17.g5 ©a2 18.c4!.

T_._.tM_ jJ_.lJj. ._J_Js.j _._._.iI ._Ii._._ _._._N_. Di.bQi._ _.kR_._R But I think I found an idea for Black in this line: the very interesting knight sacrifice 18...Àd5!? 19.cd5 cd5 (opening the line for the rook). Let’s look at the various possibilities: A) 20.Õde1 Õfc8 21.Ãc3 b5 22.©b5 Õc3! 23.bc3 Ãd6 wins for Black; B) 20.Ãe1 Õfc8 21.®d2 ©b2 nets three pawns for a piece and looks better for Black; C) 20.Ãc3 Õfc8 21.©d3 b5 is good for Black. With best wishes, B. Shankarasubbu Tiruchendur, India

New Ideas in the Fritz by Jose Lopez Senra KP 12.6 (C57)


Fortunately this wasn’t the end for Ivanchuk in London. In the final rounds he managed to win two fantastic games against the tournament victors. It would be interesting to know whether Vladimir Kramnik, who decided to play the Pirc in his decisive game against Vasily Ivanchuk, was aware that Vasily had written the Foreword for the book The Perfect Pirc-Modern by GM Viktor Moskalenko, published by New in Chess earlier this year...?

In the Survey ‘Interesting Developments in the Fritz Variation’ by A.C. van der Tak in Yearbook 103, in the game Ivanov-Podvoysky, corr. 2010, White had a very good game and the line 15...f6 seemed to be refuted. But in my opinion, the novelty 18...fe5! seems to maintain equality. 1.e4 e5 2.Àf3 Àc6 3.Ãc4 Àf6 4.Àg5 d5 5.ed5 Àd4 6.c3 b5! 7.Ãf1 Àd5 8.cd4

Too Optimistic? KP 13.9 (C56)

About the variation 1.e4 e5 2.Àf3 Àc6 3.Ãc4 Àf6 4.d4 ed4 5.e5 d5 6.Ãb5 Àe4 7.Àd4 one could probably write a bulky monograph by now.

Among others, in Chess Openings for White, Explained by Alburt, Dzindzichashvili and Perelshteyn (Chess Information and Research Center, 2007) the authors have an optimistic view on this line for White. Too optimistic, in some cases. For example, after 10...Àd2 11.©d2 0-0 12.0-0 Ãb6 13.Àb3 ©e7 14.Õae1 a5 15.©c3 a4 16.Ãc5 Ãc5 17.Àc5 they conclude correctly that White is better, but if Black plays 15...©b4! instead of 15...a4, there is no advantage for White in sight. And after 10...©h4 11.0-0 (’Black’s queen on h4 is a paper tiger’) 11...0-0 12.Àe4 ©e4 13.Õe1, they remark: ‘Now neither 13...©e5?, nor the more solid 13...©h4 is sufficient

More Trouble in the Carlsbad By Luis Rodi QO 11.4 (D36)

In high-level games, lately, not many players liked the black side in Botvinnik’s Carlsbad scheme of the Queen’s Gambit. This line is characterized by the move order 1.d4 Àf6 2.c4 e6, and only if 3.Àf3 then 3…d5, as played, for instance, by Anand and Kramnik. Plans with Àf3 are less critical in the Exchange scheme. White players prefer to continue with 4.Àc3 or 4.Ãg5 there. When Black plays 1.d4 d5 2.c4 e6, after 3.Àc3 he may either choose 3…Ãe7 or 3…c5, while 3…d5 allows 4.cd5 ed5 5.Ãg5 c6 6.©c2 Ãe7 7.e3 and Ãd3, Àge2 (Botvinnik’s idea, refined by Kasparov). One of the secondary paths employed to avoid this latter line is the lateral development 6…Àa6, when the main line runs 7.e3 Àb4 8.©b1 g6 9.©d1 (White’s move order is a well-known recipe designed to avoid Black’s main counterplay idea, …©a5). Meanwhile, in a recent game Peter Svidler showed us another way: Svidler,Peter Harikrishna,Pentala Germany Bundesliga 2012/13 (14)

1.c4 e6 2.Àc3 d5 3.d4 Àf6 4.cd5


Years ago, the Exchange Variation of the Queen’s Gambit was considered quite inoffensive, but in recent times Botvinnik’s plan with Àge2, f2-f4, e2-e4 – and Kasparov’s practical contribution – has changed the minds and evaluations. Today this is the main line in the Queen’s Gambit.


T_._Ml.t jJ_._J_J ._J_.j._ d._J_L_. .s.i._._ _.n.i._. Ii.q.iIi _.r.kBnR

Another way to avoid the critical positions from the Exchange system is 4...Àd5, as played by Kramnik against the same Svidler in the first round of the Candidates tournament in London 2013. After 5.e4 Àc3 6.bc3 c5 we are in the main line of the Semi-Tarrasch Defence. The game continued 7.a3!? cd4 8.cd4 e5 9.Àf3 ed4 10.©d4 ©d4 11.Àd4 Ãe7 12.Ãe3 0-0-0. This position offers some initiative to White, because he has more space and active pieces; however Black’s position is solid and he has a pawn majority on the queenside – a good perspective for the endings. See also the Survey by Alexander Finkel elsewhere in this Yearbook!



Peter Svidler

6.e3 can transpose, but Black has an independent way here with 6...Ãf5.

Surprise! Despite its natural look, this move is rarely employed. The main line is 8.©b1! g6 9.©d1! (a smart order to avoid Black’s counterplay connected with ...©a5) 9...Ãf5 10.Õc1 with the idea a2-a3. A recent example is 10...Ãe7 11.a3 Àa6 12.Ãa6 ba6 13.Àge2 0-0 14.0-0 Õc8 15.Àa4 Àe4 16.Ãe7 ©e7 17.Àc5 (17.Àec3!?) 17...a5 (17...Õb8!?) 18.©a4 (better is 18.Àe4 Ãe4 19.©d2Ç) 18...Õb8ÿ LupulescuGrachev, Germany Bundesliga 2012/13 (6).


8...Ãf5 9.Õc1 ©b6N

This try is designed to avoid the Botvinnik scheme, but also to deflect White to the main theoretical lines. Black wants to exploit White’s order with ...Àb4 and ...Ãf5.

ago in his acclaimed book Secrets of Modern Chess Strategy. Keeping up to date in the whole spectrum of chess openings is a difficult task nowadays, so I was struck when I saw the game Rauf Mamedov-Leinier Dominguez from the recent Russian Team Championship 2013: I had not seen this 7...g5 before, and it is, of course, very far from the traditional ways of approaching this kind of positions by Black. Going a little deeper into it, I found that the first to play this move was the Russian master Vladimir Nevostruev in the Russian Cup 2003, against Alexey Pridorozhny. The first test was not successful, although the opening had nothing to do with it, as Black obtained a big advantage right away. This unorthodox approach made it into high-level chess in 2011, when Alexander Morozevich used it vs. Alexander Delchev in the European Team Championship in Porto Carras. Although the line at large is not too developed yet, a main path has been more or less established already after 8.c3 g4 9.Àh4, which was precisely the way in which our central game developed:

Most defenders of the black side first attack the e4-pawn by 9...©e6 in order to force White to play d2-d3 to defend it, thus interfering with White’s intention of breaking in the centre with d2-d4. But at the same time the black queen occupies a position in front of Black’s e-pawn, a detail that hinders Black’s deployment as well. As a sample, I show the continuation of Delchev-Morozevich (already mentioned in the introduction): 9...©e6 10.d3 0-0-0 11.Ãf4!? d5 12.Àd2 Àh5 13.Ãg3 Àg3 14.hg3 h5 15.Àb3! b6 16.d4 c4?! 17.Àd2 Ãh6 18.Àc4! and although the fight is still in full swing, White has the better prospects. The less restrictive text move was introduced by Vachier-Lagrave in his encounter with Eltaj Safarli in the World Cities 2012 Tournament held in Al-Ain. A third alternative, 9...Ãh6, has also been played a couple of times by lower-rated players. 10.d4 d5 11.e5 Àe4 12.Àd2N

White takes a wise decision and gives perpetual check. Allowing an exchange of queens would make Black’s king safe, and then the latter’s strong pawn centre might have a say. For instance: 23.©d7 Õd7 24.Àf5 Ãf8 or 23.©a6 ©b7!, both of which lines are very unclear.

14.cd4 was also possible. In that case 14...Àd4 15.©e3 Àc6 16.b4 would have led to a very sharp battle where White seems to have compensation for the pawn.

This second test of 9...0-0-0 at a very high level was, like the first, satisfactory for Black. So it is White’s turn now. 19

Hardcore Pawn Sacrificing

The Grünfeld Indian Defence is no place for pawn sacrifices. Black must fight for counterplay to offset White’s usual superior central occupation. But the following example takes the principle to the extreme:

the audacity of this simple continuation, which will surely compete with the well-traveled 4...Àe4. Giri quoted his teammate, Ivan Sokolov: ‘If Ãg5 doesn’t even threaten to take on f6... then something must be wrong with it.’ 5.Ãf6

In about 15% of the games since 2006 White has eschewed the pawn with 5.e3. It’s a bit difficult psychologically to admit that your last move indeed did not threaten to take the d5-pawn... on the other hand there is the pull of avoiding your opponent’s preparation and ‘just playing chess’. In this case White cannot slow the game down because Black’s counterplay comes quickly with 5...c5. It’s interesting that when ‘Board 2’ faced 4...Ãg7 in 2010, Ivan Sokolov opted for 5.e3.

I often have to convince my beginning students that paying attention to pawns is worthwhile (though they are somewhat convinced by the magic of promotion). My advanced students, on the other hand, are often guilty of ‘pawn counting’ – holding on to material at the expense of everything else in the position. It seems today’s grandmasters are often sophisticated versions of my beginners. Chess in the 21st century values the initiative so highly that pawn sacrifices are springing up in unlikely places.

It’s fair to say that White need only avoid a few pitfalls from here. Sandipan defended accurately to reach a winning endgame but went so far astray that he even lost! White should not be too tight with his pawns either in such a sharp opening. Let’s consider this example from New In Chess 2013/1 (also featured in Damian Lemos Sarro’s Survey in Yearbook 105).

Fressinet was surprised by this quick and confident novelty, anticipating only 11...©a5 12.Õc5 ©a2 13.0-0 with many possibilities. His comment was noteworthy: ‘Generally speaking, White’s enormous advantage in development and occupation of the centre compensate lavishly for the sacrificed pawn.’ A bold statement to be sure, but backed up by LaznickaNavara, Novy Bor m-3 2011: 13.0-0 Àa6 14.Õc2 ©a5 15.©b1 ©d8 16.Õfc1 b6 17.©a1 Àb4 18.Õb2 f5 19.g3 e5 20.de5 Àd3 21.Ãd3 ©d3 22.Õb6 with a clear advantage. 12.Àc4

Fressinet considered 12.Õc2 ©a3 13.Õc5, looking to transpose into the aforementioned line. But the queen is not forced to take on a2, and 13...Àc6 14.©b3 ©b3 15.Àb3 a5 looked okay for Black. To flesh this out a bit, I can add 16.a4 Õd8 17.d5 Àb4 18.0-0 e6 19.Õa5 Õa5 20.Àa5 ed5 with approximate equality. Fressinet may not have been aware that 11...©a3 had been played from the diagrammed position, and after 12.Õc5 (12.Àc4 ©a6) David Navara took the a-pawn on his own free will: 12...©a2 13.0-0 Àc6 14.Õc4 ©a5 15.d5 Àe5 16.Õa4 ©c7 17.f4 b5


17...©h4 18.Ãf2 Ãg3 19.hg3! ©h1 20.Ãf1 b4 21.Àb5 looks dubious for Black; suddenly he is the one suffering on the dark squares. White can sacrifice in a similar vein after 17...b4 18.Àd1 f5 19.Àf2!? Ãb2 20.0-0.

Laurent Fressinet

(Kasimdzhanov-Navara, Wijk aan Zee 2009 – YB/105-196) and now 18.Õb4 a5 19.Õb5 Àd7 20.e5 looks quite favourable for White.

Now I’m inclined to side with Fressinet and agree that Navara was too greedy here. Still, it takes two to tango, and this shows how the sacrificers out there can always find people to take their pawns. 12...©b5

Fressinet pointed out an improvement, 12...©b4 13.Ãd2 ©b5 14.d5 ©e8! (the c5-pawn is not under attack). After 15.0-0 b5 16.Àa5 c4, Fressinet is still optimistic about White’s chances, though he may get some argument here. 13.d5 b6 14.0-0 ©d7

Benjamin’s Opening Takes

Fressinet considers White to be much better here, and he went on to win rather smoothly. Black’s structure is sound and he is in no immediate danger... yet I wouldn’t want to defend this position either. The Catalan has grown immensely in importance over the last several years. Nowadays we can count on the biggest names (Kramnik, Aronian, Gelfand and Carlsen, to name a few) debating this opening when they get together. I think the Catalan started to become a more potent weapon when players found more and more positions where they can genuinely sacrifice the pawn on c4. Obviously, when Black overvalues the c4-pawn, he will be living dangerously, as the following game indicates: Giri,Anish Morozevich,Alexander Beijing rapid 2012 (2)

1.d4 Àf6 2.c4 e6 3.Àf3 d5 4.g3 dc4 5.Ãg2 b5?!

Black often throws in this check to entice the bishop to d2, where it occupies a square that can often be used by the b1-knight. 5.Ãd2 Ãd6

In earlier games White generally continued with the solid 9.Ãg5 h6 10.Ãf6 Àf6 11.Àbd2, though Black will have the bishop pair to compensate for White’s spatial superiority. One example is 11...b6 12.e4 Ãe7 13.Õfd1 Ãb7 14.Àe5 Õc8 15.Õac1 dc4 16.Àdc4 b5

17.Àe3 ©b6ì Gelfand-Ponomariov, Odessa 2008. White can also try 9.Ãf4 here. 9...dc4 10.Õfd1

This seems to be a novelty. The resulting play indicates why Kramnik chose this rook; previously 10.Õad1 has been tried. Docx-Meier, Antwerp 2010, continued 10...©e7 11.Ãg5 h6 12.Ãf6 Àf6 13.Àd2 e5 14.Àc4 ed4 15.Àd6 ©d6 16.e3 c5 17.ed4 cd4 18.Àb5 ©b6 19.Àd4 Ãg4 and Black was already more comfortable. 10...©c7 was tried in TadicAbramovic, Kragujevac ch-SRB 2011: 11.e4 e5 12.Ãg5 h6 13.de5 Ãe5 14.Àe5 hg5 15.Àc4 g4 was perhaps a bit better for White, but I don’t think Black has to fear 12...b5 13.de5 Àe5 14.Ãf6 gf6. Finally, 10.Ãg5 h6 11.Àe4 Ãe7 12.Àf6 Ãf6 13.Ãf6 ©f6 14.©c4 e5 15.de5? (15.Õfd1ì) 15...Àe5ì was Maheswaran-Sangma, Visakhapatnam Open 2011. 10...©c7 11.Àg5!

Down to his final minute, Ivanchuk would be courting disaster with 29...®f8 30.©b8 Àc8. After 31.h4!, preventing Õg5, things are likely to go downhill while Black is limited to sitting around. Perhaps Kramnik should have rolled the dice on the clock, but he made a principled decision. 30.Àh4 ®g7 31.Àf5

White’s c4-pawn has been replaced by a doubly-defended black one. White has moved his bishop two more times and retreated his queen. And yet, Black is hardly comfortable here. The pawn on c4 will be hard to hold, and the c8-bishop is feeling quite miserable.



The queen is unstable on d5, but I’m not sold on this move. The queen will be shunted off to the side and c4 will eventually drop. Here the computer provides an interesting idea: 12...a5!?, with two plausible continuations: 13.Àe5 ©b5 14.a4 ©a6, or 12.Àbd2 a4!?. In both cases we may have a more lasting gambit. I don’t think Black is worse.

This break doesn’t seem to achieve much because White can maintain the d4-pawn while the g2-bishop grows in strength. In a later game Black tried 15...Àc3 16.bc3 Àd7 17.Àec4 Àb6 18.©b3 Àc4 19.Àc4 Ãd7 20.e3 b6 (Schneider-Atlas, Graz 2013), but Black is groveling here as well. 17...e5!? is tempting, as this is the move Black really needs to get in.

White has a serious advantage in the endgame. Leko barely managed to hold a draw, and after 134 moves at that!

Sjugirov ambitiously preserves his bishop and hopes to exploit the e4-knight tactically, though the simple 15.Àbd2 looks preferable to me.

In a later game the same idea was applied in a slightly different position.

Giri missed 14.e4 Ãe7 15.Àg5!, slamming the door shut on the queen while threatening e4-e5. Even after the missed opportunity Giri maintained a promising position and won in good style. As long as Black still has to solve the typical problem of mobilizing the queen’s bishop, White doesn’t seem to care about the pawn count. But as I see from two games in the thirteenth round in the FIDE Candidates’ tourna-

In both cases Black chose to give back the pawn to reach a solid position with relatively equal chances. We’ve only just scratched the surface of contemporary gambit play. Some new ideas are motivated by the improved recognition of compensation in 21st century chess engines. The long departed Frank Marshall might be amazed to learn that his signature gambit apparently can be played in almost any form, like the ‘Accelerated Gajewski Gambit’ (detailed by GM Larry Kaufman in YB/104): 1.e4 e5 2.Àf3 Àc6 3.Ãb5 a6 4.Ãa4 Àf6 5.0-0 Ãe7 6.Õe1 b5 7.Ãb3 0-0 8.c3 Àa5!?

Black hasn’t achieved ...d7-d5 yet, as in more familiar Marshall forms, but it’s coming right up. More practical tests will be heartily welcomed, but I’ve seen enough to know that I no longer can say what a pawn is worth.



Opening Trends as Reflected in the Candidates’ Tournament Two games by Kramnik in this variation were important not for the novelties, but for the trend chosen.

Nimzo-Indian Defence To the childish question ‘What is the best opening for Black?’, I definitely know the answer – it is the Nimzo-Indian Defence. Over the past forty years – before Fischer’s triumphal ascent to the chess throne the approach to opening preparation was not so all-embracing and concrete – there has never been a period when Nimzowitsch’s invention has faded into the background. There have been problematic years for both the Grünfeld Defence and the King’s Indian. The Queen’s Gambit and the Slav Defence have not always been in favour. And this is to say nothing about the open and semi-open games – there White has periodically been able to set the opponent difficult problems. Even in the Najdorf Variation... take a look: who of the chess elite plays it now? They are afraid, and prefer to hide behind the ‘Berlin Wall’ in the Ruy Lopez!

and now instead of the strange retreat 18...Àe8? the simple 18...Ãe7 19.Àf6 Ãf6 20.Ãe4 g6 was possible. I should add that the plan of transposing into a position with an isolani was preferred by Leko in a theoretically important game with Ivan Sokolov (Wijk aan Zee 2013). There Peter demonstrated the reliability of the variation 10.Ãg5 Ãb7 11.Õc1 h6 12.Ãh4 Àc6, as can be seen in Viacheslav Ikonnikov’s Survey on page 162. If Leko and Kramnik choose one and the same variation, this must mean something!


King’s Indian Defence When I was at school, one of my favourite books was The King’s Indian Defence, written by perhaps the main advocate of this opening, Efim Petrovich Geller. It was pub-

lished in Russian some time between the Baguio (1978) and Meran (1981) matches for the World Championship, and later it was translated into other European languages. From it I learned that the main replies to the King’s Indian Defence are the Classical Variation 5.Àf3 0-0 6.Ãe2, the Sämisch Variation 5.f3 and the variation with g2-g3. Today the Classical Variation has still retained its position, whereas in recent decades the Sämisch has somewhat faded into the background. 1.d4 Àf6 2.c4 g6 3.Àc3 Ãg7 4.e4 d6 5.f3 0-0 6.Ãe3

The variation of Friedrich Sämisch has been played throughout his career by Anatoly Karpov. But he began employing it, I think, under the influence of his friend and helper Yury Sergeevich Razuvaev, who had an excellent knowledge of this variation. Incidentally, Karpov and Razuvaev wrote the corresponding section in the first edition of the Yugoslav Chess Encyclopaedia. In his later years Razuvaev instilled his love for the Sämisch in his pupil Evgeny Tomashevsky. Today it is Evgeny and Nikita Vitiugov who are restoring the former prestige of the variation. It remains to add that Svidler, who in London twice played this variation, was helped in his preparations by Vitiugov... 6...c5!

Efim Geller

maestro. Other continuations allow White a broader range of options. It is interesting that Kasparov, who in this variation tried virtually all the options, not once played 6...c5, having a leaning towards the classical King’s Indian advance 6...e5. There is a simple explanation for this: after the acceptance of the sacrifice 7.dc5 dc5 8.Ãc5 in a number of lines a draw results almost by force.

It is this gambit variation that has forced many grandmasters to give up the variation of the German

The fashionable move. It was played twice last year by Grischuk, and it was after this that the move attracted attention.

In contrast to the pseudo-sacrifice 12...Àeg4 this is a completely real and far from obvious piece sacrifice! Summing up the Candidates’ tournament, Garry Kasparov singled out this game, saying that he had analysed the knight sacrifice back in the 1990s, and later he showed it to Nakamura, but Hikaru did not have an opportunity to drop this opening bomb. Incidentally, the consequences of the novelty were assessed by Kasparov as ‘There Black is even better’. To me this seemed questionable, but, of course, to the owner of the patent things are clearer... In the game there followed 13.Ãc4 b5 14.Ãb5 ed5 15.e5 de5 16.fe5 Ãg4

and after a grand battle things ended in a draw. But during the last few years the greatest King’s Indian metamorphosis has occurred with the g3 Variation – it has simply disappeared! The reason for this is a cunning plan by Black. He does not hurry with

the advance of his d-pawn. If in combination with g2-g3 White develops his knight at c3, there immediately follows ...d7-d5, resulting in an advantageous variation for Black of the Grünfeld Defence. Hence for the moment White should play without touching his queen’s knight. Then Black carries out the ...c7-c5 advance, and now in event of d4-d5 the flank blow ...b7-b5 follows – there is no knight on c3! But if White tries to take play into the English Opening, i.e. maintains the pawn tension in the centre, Black himself exchanges on d4. And if on the previous move White has castled, the symmetric blow ...d7-d5 equalizes, or if he has played Àc3, then with 7...©c7 Black attacks the c-pawn, again preparing to strike at the centre. If you don’t believe that with one paragraph of general reasoning you can defeat an entire variation, look at Radjabov’s games from the last few years! However, it would appear that Vladimir Kramnik also doubted whether Black’s life could be so serene... Kramnik,Vladimir Radjabov,Teimour London ct 2013 (11)

As the course of the game showed, White has succeeded in retaining the initiative. Queen’s Gambit Accepted The Aronian-Svidler game proceeded somehow imperceptibly, without any raptures or commentaries, but meanwhile, for a reply to the sacramental question ‘how 32


Against Karjakin in last year’s Russian Championship ‘Superfinal’, Daniil Dubov played 10...Õa7, which is less natural. Clearly, with the rook on b8 the a-pawn is inadequately defended, but Svidler had provided for every eventuality. 11.0-0 Ãe7 12.©e2 0-0 13.Ãb2 c5 14.Ãa6 Ãa6 15.©a6

But the point is that after 3...a6! White’s resources are very restricted. If in this way Black can make a draw, then in the Queen’s Gambit Accepted there is only one remaining option for White – 3.e4. But one line is easy to prepare, and also the original positions arising after 3.e4 are not to everyone’s taste. It is possible that soon the Queen’s Gambit will have to be approached via the cautious move order 1.d4 d5 2.Àf3 Àf6, or, which would be altogether laughable, via the English Opening – 1.c4...

he was forced to return it. Soon a draw was agreed. You might think: so what?! Okay, Black made some improvement and he equalized – but nothing special occurred.

White’s last move drew attention after two wins by Morozevich over Giri in last year’s tournament in Beijing. In the blitz game the Dutchman played 5...dc4, but he soon encountered problems: 6.e4 Ãg4 7.Ãc4 0-0 8.e5 Àfd7 9.h5!.

Black does not have any appreciable problems. I have not uttered a word about the battles in the open and semi-open games – this is unfair, but I have a justification. In London White ventured to open with the king’s pawn in only a quarter of all the games, and this is no accident. In recent years the reliability of the Berlin Variation and the Marshall Attack have enticed into the ‘Spanish camp’ many devotees of the semi-open games. And in the Ruy Lopez itself White prefers to avoid both the ‘Berlin’ endgame, and the forcing lines of the Marshall Attack, by using the variation with d2-d3. Thus in both cases the main battle develops in the Ruy Lopez with d2-d3, the only difference being that in the ‘Berlin’ interpretation the black bishop ends up on c5, and in the ‘Marshall’ on e7.

Ts._M_.t jJ_DjJlJ ._.j.sJ_ _._._._. ._InI_._ _.n._._. Ii._.iIi r.bQk._R Chess in the modern information age develops with leaps and bounds. The amount of theory to be studied grows each day, and this is not to everyone’s taste. In 1994, for example, the Huge Database consisted of only 300,000 games, whereas now an average database has 6,000,000 games. Nowadays we see more and more players (including the world top) selecting an approach that moves away from the main theoretical lines. The players are not trying to compete in the depth of their home preparation, but choose less deeply analysed lines that do not promise a large advantage. Instead, they try to outplay their opponent in the later stages of the game.

We used to see this approach only in sub-top and lower-level tournaments, and in certain openings, now it is common in all tournaments and in all openings. The Latest Trends

One of the variations that require a lot of theoretical work is the Najdorf Sicilian. In the Yearbooks we have been studying different ways of avoiding it (look at earlier Surveys written by yours truly, for example!). 3.Ãb5 remains a popular move to avoid the Najdorf or other extensively analysed variations of the Sicilian Defence. At the moment we see this move being played by Carlsen, Anand (who himself became a victim of it several times), Caruana and other strong players. And we feel that a Survey has become necessary to inform the Yearbook reader about the latest trends and developments in the variation beginning with 1.e4 c5 2.Àf3 d6 3.Ãb5 Ãd7 4.Ãd7 ©d7 5.c4 (another plan, with castling, c2-c3 and d2-d4, will not be studied in this Survey) 5...Àf6 (the pawn grab 5...©g4 6.0-0 ©e4 7.d4 is extremely dangerous for Black; another move order, 5...Àc6 6.Àc3 Àf6 7.d4 cd4 8.Àd4 and then 8...©g4, leads to a slightly better endgame for White after 9.©g4 Àg4 10.Àc6 bc6 11.Ãf4 as in

Viswanathan Anand

Tiviakov-Gerzhoy, Ottawa 2007) 6.Àc3 g6 7.d4 cd4 8.Àd4 Ãg7 (see the diagram above). Key Differences

What we now see on the board is the pawn structure that is typical for the Maroczy System against the Accelerated Dragon. The key difference compared with the Maroczy is the fact that the light-squared bishops have been exchanged. Although in the Maroczy, White’s light-squared bishop is always bad, its exchange still favours Black, who gets more space to manoeuvre his pieces. But the most important thing is that after the bishop swap it is much easier for Black to organize the freeing move …d6-d5. In most cases, if Black fails to free himself by playing …b7-b5 or …d6-d5 at some 37

point, he will end up worse. White can easily stop the possible advance …a7-a6 and …b7-b5 by playing a2-a4, but it is not so easy to stop the plan with …e7-e6 and …d6-d5. So most of the play we will see in this line will be about this break-through advance! The following games clearly demonstrate the dangers in Black’s position and what can happen to him if he fails (or does not want) to play …d6-d5: Tiviakov-Idani, Tiviakov-Ivanchuk, Tiviakov-Collas, BruzonJones. And of course, this selection can go on, on and on… In the diagrammed position, White has a choice of four main plans: A) 9.0-0, B) 9.h3, C) 9.f3 and D) 9.Àde2.

lead to complications after 10...©e6 11.Àd5 ©e4 12.Àc7 ®d7 13.Àa8 ©c4. Two pawns for the exchange turned out to be more than enough for Black in Naiditsch-Anand, Baden-Baden 2013. Although I believe that White can improve on his play, it’s difficult to believe that he can get an advantage here. If Black is afraid to go into complications, he can also opt for 10...0-0, transposing to a line which we will study later – 9.Àde2 (Variation D). After 9...Àc6 the best move for White is 10.Àc2. The ensuing position was quite popular a long time ago, but now it is rarely seen. But it is worth returning to it, trying to discover new resources for White!

Variation A

Variation B

9.0-0 is a natural enough move.

The idea behind 9.h3 is to try and finish the development with Ãc1-e3 and 0-0. If White succeeds, he will stand slightly better compared to the set-up with f2-f3, Ãe3, 0-0. Unfortunately for White, after 9.h3 the pawn on e4 remains insufficiently protected, allowing Black to use a tactic to solve his problems. After the correct 9...©c7 White has a choice between 10.b3 and 10.©e2.

Ts._M_.t jJ_DjJlJ ._.j.sJ_ _._._._. ._InI_._ _.n._._. Ii._.iIi r.bQ_Rk. However, here it seems less dangerous for Black because after 9...0-0 White has no time to play 10.f3 or 10.h3, since after both moves Black equalizes easily with 10...Õc8 11.b3 d5!!. In order to keep fighting for an advantage, White probably has to play 10.b3 Àc6 11.Ãb2, although it seems that Black is OK then after 11...e6, preparing …d6-d5 (see Krayz-Roiz, Israel tt 2004). Another possibility for Black is 9...Àc6, forcing White to move his knight away from the central square d4. Now 10.Àde2?! can 38

Ts._M_.t jJd.jJlJ ._.j.sJ_ _._._._. ._InI_._ _.n._._I Ii._.iI_ r.bQk._R 10.b3 forces the game into an equal ending: 10...©a5 11.Ãd2 Àe4 (11...Àc6 deserves attention as well) 12.Àe4 ©e5

13.©b1 f5 14.Ãc3 ©e4 15.©e4 fe4 16.Àb5 Ãc3 17.Àc3. This variation is presented in the game Bologan-Naiditsch, Spain tt 2011. The only way for White to avoid an equal ending is to play 10.©e2, as yours truly did in his game against Hou Yifan in Hoogeveen 2012. Although the position remains equal, thanks to the fact that all pieces are present on the board, White has more chances to outplay a weaker opponent (or lose to a stronger one). In the above-mentioned game I managed to exploit the then Women’s World Champion’s mistake in the complications and win the game. Variation C

The move 9.f3 and the following set-up have always been White’s main weapon. After 9.f3 0-0 (please note that 9...©c7, played in analogy with Variation B, is a mistake. Anand played it once against Carlsen and lost badly. I think that Anand had simply confused two lines: 9.f3 with 9.h3) 10.Ãe3 Àc6 (other moves are worse, for example 10...Õc8 turns out to be a loss of time, since Black is unable to carry through the …d6-d5 break at an opportune moment, see Tiviakov-Usmanov, St Petersburg 2004) 11.0-0 a6 12.a4 e6, one of the main positions for the evaluation of the system with 3.Ãb5 as a whole arises.

White has several different ways to try to stop the break …d6-d5. 13.Àde2 occurred in the game Tiviakov-Nakamura, Hoogeveen 2012. This game has been analyzed deeply by the present author, and includes in the notes all the games played after it. Although White manages to stop …d6-d5, Black gets very good and active play for his pieces, which secures equality. 13.Õc1 is an old move, played for the first time by Sadvakasov against Kasparov in Astana 12 years ago.

9...Àc6 10.f3 (10.0-0 is worse and leads us to the variation 9.0-0 Àc6 10.Àde2, studied earlier) 10...0-0 11.0-0 a6 12.a4 e6 13.Ãg5.

It doesn’t prevent …d6-d5. Adams repeated this move in December 2012 against Dominguez Perez in London, but also failed to get an advantage.

We can see that in comparison to all the variations studied previously, White has developed his bishop to a much more active place, once and for all preventing Black’s main strategic idea of …d6-d5. Black has lots of different ways to regroup his pieces and create activity. In the Main Game of

Variation D

In my opinion, 9.Àde2 is the most promising move for White at the moment.

the present Survey, CaruanaAnand, Sao Paulo/ Bilbao 2012, presented at the end of this Survey, Black failed to put his pieces on the optimal places, missed an obvious tactic and later found himself on the verge of losing. Clearly, Black must have enough resources to equalize, but the complexity of the position prevents us from coming to a definite conclusion on how to do so. The Final Conclusion

The bishop check 3.Ãb5 is becoming more and more popular. Although it doesn’t promise much of an advantage if Black plays correctly, it remains a good idea to avoid lots of theory in the main lines of the Sicilian Defence. Another plus for White is that in the ensuing positions he does not run so much risk to lose (as in the Najdorf), since after the central exchanges (when Black has played …d6-d5) White cannot lose if he doesn’t want to play for a win. At the moment, the most promising variation for White remains the one with Àde2 and Ãg5. My prediction is that we will see many more games with this line in the near future. And who knows, maybe another Survey will be required soon!

A New Idea in the Hungarian Variation by Alexander Raetsky and Maxim Chetverik e4 Àf3 d4 ©d4 c4 ©e3!?

T_LdMlSt _J_.jJjJ J_Sj._._ _._._._. ._I_I_._ _._.qN_. Ii._.iIi rNb.kB_R 4...a6, preventing Ãb5, is considered to be a sound scheme against the Hungarian Variation. In reply White prefers the Maroczy set-up 5.c4, and after 5...Àc6 he traditionally retreats his queen to d2. However, in 1973 the Yugoslav grandmaster Ljubomir Ljubojevic surprised Walter Browne by retreating to e3. After 6...g6 7.Àc3 Ãh6 8.©d3 Ãc1 9.Õc1 Ãg4 10.Àd4 Àf6 11.Àc2 0-0 approximate equality resulted. China

By the efforts of the ex-European champion Bartlomiej Macieja and strong Chinese players (Zhang Zhong, Ni Hua, Hou Yifan) since 2006, the variation with 6.©e3 has occurred in serious tournament practice and 46

has become, it can be said, a variation of the 21st century. It is worth mentioning that, according to the database, more than half of the games have been played by titled players. Virtues

The virtues of the queen’s position on e3 are considerable. The queen defends the e4-pawn and supports the e4-e5 advance. The development of the rook on d1 will signify opposition on the central file with the enemy queen. Finally, if necessary the dark-squared bishop obtains the d2-square. The drawback to the queen’s position on e3 is that it is subject to attack by ...Àf6-g4, against which (and also against ...Ãc8-g4) the prophylactic h2-h3 is effective. In the initial position of the variation Black has three main options: 6...e6, 6...Ãg4 and 6...g6.


1. 2. 3. 4. 5. 6.

Ljubomir Ljubojevic

evaluation for the Hedgehog: Black is slightly cramped, but he is ready to free himself at the appropriate moment. Controling the Centre

6...Ãg4 involves the idea of exchanging bishop for knight, to strengthen Black’s control of the centre.


6...e6 leads to a typical ‘hedgehog’ with the rather unusual position of the queen on e3. It is amusing that the game KarpovGheorghiu (Leningrad 1977), and also a number of others, via the move order 1.c4 c5 2.Àf3 Àf6 3.Àc3 e6 4.g3 b6 5.Ãg2 Ãb7 6.0-0 Ãe7 7.d4 cd4 8.©d4 d6 9.Õd1 a6 10.e4 Àbd7, gradually arrived at a line analysed in the Macieja-Becerra game.

T_.dMlSt _J_.jJjJ J_Sj._._ _._._._. ._I_I_L_ _._.qN_. Ii._.iIi rNb.kB_R After 6...Ãg4 7.Ãe2 he comparatively rarely plays 7...e6, al-

though the Chinese player Yu Wenjun successfully upholds Black’s interests here. For example, 8.0-0 Àf6 9.b3 Ãe7 10.Ãb2 0-0 11.Àc3 ©a5 12.Õfd1 Õac8 13.a3 Õfd8 14.b4 ©c7 15.Õac1 Ãf3 16.©f3 Àe5 17.©e3 Àc4 18.Ãc4 ©c4 19.Àd5 Àd5 20.©g3 Àc3 21.Õc3 ©e2 22.©g7 ®g7 23.Õc2 Ãf6 24.Õe2 Ãb2 25.Õb2 d5 and the complications gave Black the more pleasant endgame (Gu Xiaobing-Yu Wenjun, China 2012). Black much more often combines 6...Ãg4 with the fianchetto of the dark-squared bishop. The development of the bishop on the long diagonal allows Black to fight successfully for the key d4-point. For example, AlexeevIdani; Bitoon-Wen Yang. A Modern Tabiya

The most usual continuation here is 6...g6. After the most accurate move order 7.h3 Ãg7 8.Àc3 Àf6 9.Ãe2 0-0 10.0-0 Àd7 a modern tabiya of the variation in question is reached.

Occasionally the queen’s rook also comes to c1 (Zviagintsev-Kornev). But since in the tabiya White is aiming for action on the queenside with b2-b4, 11.Õb1 seems more logical. The sacrifice of the central pawn in the variation 11...Àc5 12.b4 Ãc3 13.©c3 Àe4 is topical (R.Fridman-Jens; Macieja-Perez Olarte). White undoubtedly gains compensation, thanks to the weakened position of the black king and his active pieces. In practice Black chooses one of two plans. The quiet one consists in completing his queenside development with ...b7-b6,

...Ãc8-b7 and ...Õa8-c8 followed by the restriction of White’s actions (Motylev-Wei Yi; MaciejaGuliev). The dynamic plan involving ...f7-f5 is more attractive. Black slightly weakens his position, but he activates his pieces (Borulya-Chlost; Zhang ZhongLi Shilong; Ni Hua-Xia Deshun; Boros-Oleksienko). In this tense battle Black’s chances are probably not worse. Black’s plan involving ...e7-e5, with the idea of establishing his knight on d4, is rather dubious. In this case the d5-point is irreparably weakened and Black has to reckon with the highly promising exchange sacrifice Õd4. Hamdouchi-Sreeves is a good example. Conclusion

The queen retreat 6.©e3, which has become popular with strong players, enables White to fight for a small advantage. Black’s best reply is probably the plan with the immediate 6...Ãg4 followed by the fianchetto (Carlsen-Gelfand).

T_L_Ml.t jJ_.jJjJ ._Sj.s._ _N_._._. .dB_I_._ _.n.b._. I_I_QiIi r._.k._R Since the early eighties, when I studied Fischer’s My 60 Memorable Games, I have been attracted by the move 6.Ãc4 against the most popular lines in the open Sicilian. Thirty years later I still rely on this recipe to smash Najdorf- and Scheveningen-type set-ups. Usually a messy position arises. White castles either kingside or queenside, sacrifices a piece on e6, d5 or f5, or starts a pawn-roller on the kingside. There’s always room for inventiveness! I had a lot of fun and made a high score with my beloved 6.Ãc4. But there was a slight annoyance: when Black played 6...©b6(!) in the classical varia-

tion, I was unable to reach a position to my liking. I never got anything out of the opening except a normal-type Scheveningen with mutual chances. Finally, in a desperate attempt I forced myself to analyse the consequences of the gambit 7.Ãe3!? ©b2 8.Àdb5, and after 8...©b4 9.©e2!?. This appears unsound at first sight, but the line surprised me by its richness of ideas, which I realized after I had done some work on it. This continuation, speeding up development without wasting any thought on pawns, was invented by Vladimir Lepeshkin and was first played by Igor Zaitsev in 1996. It is by far more aggressive than the previously played 9.Ãd3/Ãd5, slow moves that score very poorly in the databases. Convincing Practical Results

With fresh impressions I went on to play the gambit and won against German WGM Melanie Ohme in good style. Nearly two years passed until I got the chance to play it again at the Staufer Open in January this year. I was amused when I discovered in the database that no one had played the variation during 2012-2013, except me! Is it really this bad? No, it isn’t! I only vaguely remembered the lines I had analysed and mixed

up some ideas, but my opponent, the strong GM Alexander Zubarev, had to improvise as well! I managed to score an impressive victory and led the tournament with two rounds to go. Then I lost with black, but in the last round I faced the young Russian grandmaster Egor Krivoborodov with the white pieces and... again the gambit line came on the board! It was obvious that my opponent had prepared the variation during the night. Okay, I’d been on the night shift too: repeated my old analyses, committed the patterns and motifs to my memory, and screened the critical lines. After 9...Àe4 10.Ãf7 he shook me by 10...®d8!? without hesitation, and he kept moving very fast. How could I be so silly to repeat this risky variation? I started cursing myself...

T_Lm.l.t jJ_.jBjJ ._Sj._._ _N_._._. .d._S_._ _.n.b._. I_I_QiIi r._.k._R It took me some time to pull myself together and to avoid the traps he had laid. After a very tense struggle I won the game 55

The Critical Test of the Line

More critical in any case is 10...®f7 11.Õb1 ©a5 12.©c4 e6 13.©e4.

T_L_.l.t jJ_._MjJ ._SjJ_._ dN_._._. ._._Q_._ _.n.b._. I_I_.iIi _R_.k._R In my opinion this is the only real test for the viability of the whole variation. In all the other lines White has good chances to achieve not necessarily an advantage, but an enduring initiative and easier play. Only a handful of games were played with this critical continuation; not enough to assess the ensuing position. Computers like Black here. White is forced to give a piece, or two pieces for a rook, but to play over-the-board with uncoordinated pieces and a wandering king is not everybody’s cup of tea. Instead of the main move 13...d5 I would like to draw attention to the restrained 13...®g8!, a prophylactic move that hasn’t been played so far. No Comfortable Line for Black

Most players don’t like this kind of hullabaloo, and will look for


an easier way to handle the problem: 9...©a5 is the move that is most often played. Understandably, Black wishes to reach the home port for his buccaneer queen, but this allows White to complete his development and establish an attacking position. As a rule, White rushes the knight to d5, a menacing penetrator that Black cannot allow there, and after the swap on d5 White takes with the pawn, e4xd5, and gets pressure down the e-file. In chess moves: 10.Ãd2 ©d8 11.Àd5 Àd5 12.ed5 Àe5.

T_LdMl.t jJ_.jJjJ ._.j._._ _N_Is._. ._B_._._ _._._._. I_IbQiIi r._.k._R Here White can force the play with 13.f4 Ãg4! 14.Àd6!, but with a series of accurate moves Black should hold the balance. 13.Ãb3 leaves more potential on the board at the cost of a tempo. Instead of the usual 13...a6 with ...b7-b5 to follow (Kotronias), Black has the interesting 13...g5!?, which was introduced by Milos Pavlovic. Conclusion

At the end of the nineties, Yearbook Supervisor René Olthof wrote a Survey about this gambit line, partly based on a theoretical publication by Vladimir Lepeshkin in the Russian monthly 64 98/5. Almost 14 years have passed, and since then


and earned some prize money. His novelty (later I found a game with 10...®d8, which was not included in the databases I use!) forced me to find some only moves, but theoretically Black can only hope for equality.

Vladimir Lepeshkin

the computers have changed a lot in the chess world, especially in highly tactical opening variations. In my opinion, the ‘Lepeshkin Gambit’ has proved its strength and withstood all attempts at refutation. One such try was Zarnicki’s 9...Ãg4!? 10.f3 Àe4!?, but Olthof’s recommendation in Yearbook 51, 11.Ãd4!, proved very successful in the game Polzin-Popovic in 2001. This line is not recommended for Black.

T_._Ml.t jJ_.jJjJ ._Sj._._ _N_._._. .dBbS_L_ _.n._I_. I_I_Q_Ii r._.k._R If you want comfort you’ll get inconvenience! The strength of the gambit line lies in the fact that Black is obliged to take risks and should be well prepared; otherwise he’ll have a very hard time.

T_LdMl.t jJ_.jJ_J ._Sj.sJ_ _._._.b. ._.nI_._ _.n._._. IiI_.iIi r._QkB_R Commenting upon a Classical Sicilian game against Rauzer (Leningrad 1933) in his Half A Century of Chess, Mikhail Botvinnik writes that instead of 6.Ãe2 – when the patriarch replied 6...g6 – Rauzer later ‘introduced the move 6.Ãg5 preventing the Dragon Variation’ [my italics]. Indeed, Rauzer’s 6.Ãg5 was certainly intended to prevent the Dragon, and the move 6...g6 may be considered the biggest personal affront to his memory. Genesis

But it was yet another Soviet powerhouse, Igor Bondarevsky, who introduced precisely this move into modern practice. In the game Gromek-Bondarevsky, Lodz 1955, there followed 7.Ãf6

ef6 8.Ãe2 Ãg7 9.Àdb5 0-0 10.©d6 f5 11.0-0 fe4 12.©d8 Õd8 13.Àe4 Ãb2, and Black was already slightly better and went on to win. His Polish opponent Jozef Gromek was so impressed that he took up Black’s cause in subsequent years. In the 1960s, Oleg Chernikov started playing the Dragon versus the Rauzer, making the biggest contribution to the theory of this line. It would be most fitting to call this the line the Chernikov Variation, especially after the Russian grandmaster published his findings in SOS-3 (New In Chess, 2005). In more recent times the line has occasionally been played on the highest level. Carlsen, Nisipeanu, Naer and Vitiugov are among the incidental practitioners. The 2013 Tata Steel Chess Tournament saw a spectacular game between Nils Grandelius and 2012 junior World Champion Alexander Ipatov. This is a good starting point for a Survey on the main line starting with 8.Ãc4. A Roadmap

Following 6...g6, White has but little choice and should take up the gauntlet if he wants to achieve an opening edge. Indeed, the sharp 7.Àc6 bc6 8.e5 de5 falls short by a wide margin (both 9.©f3 and 9.©d8 promise nothing), while the tame 7.Ãe2 Ãg7 (or 7.Àb3 Ãg7 8.Ãe2) will

lead to a quiet line once favoured by Karpov versus the Dragon. This last line is playable of course, but not critical. After 7.Ãf6 ef6 White has done some serious damage to his opponent’s structure and more often than not Black will lose the backward pawn on d6. In return Black has secured the bishop pair, and in particular the dark-squared bishop can develop into a monster after a subsequent …f6-f5. The main move now is 8.Ãc4, and for the alternatives the interested reader is still best referred to Chernikov’s article in SOS-3. Black, of course, continues with 8...Ãg7.

For the only sensible alternative 9.0-0, see the great game Berg-Naer, German Bundesliga 2011/12, which demonstrates the potential of Black’s bishop 63


11.0-0-0 (for 11.0-0, see Robson-Perelshteyn, St Louis 2011), and it is only here that our roads diverge.

pair in this line. After 9.Àdb5 Black is forced to sacrifice his d-pawn with 9...0-0 and White usually grabs it with 10.©d6 (10.0-0 would transpose to 9.0-0; see the notes to BergNaer). Now there is no need to consider any other move than 10...f5, opening up the position for Black’s ‘Dragon’ bishop, and starting counterplay in the centre. White’s uncastled king now hurries to the queenside with

IiI_.iIi _.kR_._R Taking on d6 is now obviously bad for Black, but the alternatives 11...©a5 and 11...©g5 have traditionally been mentioned in the theoretical works. However, as the Game Section will show you, both moves enable White to fight for an advantage. As Sergey Shipov explains in his excellent notes, though, Alexander Ipatov obtained a wonderful position in our Main Game after 11...©b6!? 12.f4 (Shipov gives the Zwischenzug 16…Õad8! as

an important improvement for Black, instead of Ipatov’s recapture 16…fe6). Both 12.Àd5 and 12.f3 have been tried in practice, but neither move is convincing. Shipov himself notes the odd silicon move 12.Õhf1, but has difficulties believing in the idea – is this really the way forward for White? Conclusion

In conclusion, Black's offensive 6...g6 seems fully playable at present, which is mainly due to the fairly new move 11...©b6 in the main line. Unless White really wants to go for 12.Õhf1, he should perhaps seek other ways to combat the Chernikov Variation. As an appetizer, please note that I have added the game Svidler-Vitiugov, Russian Superfinal 2007, to the Game Section, even though it started with 8.Ãb5. For after 8…Ãd7 the cunning Svidler played 9.Ãc4, arguing that the bishop is in Black’s way on d7, leaving pawn d6 unprotected.

._T_Ml.t jJ_LjJjJ ._.j.s._ d._.i.b. ._.q.i._ _.n._._. IiI_._Ii r._.kB_R There are many Sicilian variations that are considered ‘smelly’ to say the least, and they tend, slowly but inevitably, to remain only as dust on an old book left unopened for many years. This might have been the fate of the 6...Ãd7 Rauzer Variation, partly because of 10.e5, followed by Kupreichik’s 13.Àb5, which was thought to be crushing. New Life

But sometimes there is a pioneer whose sigh breathes new life into an almost-forgotten line. Vladimir Kramnik is one of them, and he is getting more and more followers. But in the present case he

was not the researcher. Two grandmasters have kept playing it as Black: Konstantin Shanava and Daniil Dubov. One might make an objection about the youth of the latter, but Dubov recently drew against some of Russia’s best players, although he did not play this exact line. We decided to scrutinize his games in order to understand where the old analysis went wrong, or where Dubov did. And to our satisfaction we discovered that Black was not losing at all and that White, in fact, had to work hard to get an advantage! Two Known Paths

Still, the results are really poor for Black, since the position after 13.Àb5 is known to be rather tough to play without a computer as the defender. But does tough mean unsafe? We shall see. 10...de5 Ãc6

13.Ãb5, although a 1991 recipe from Polgar with 13.Ãc4 might also be a contender. After 13.Àb5 Dubov got perfectly reasonable positions until move 25, but he lost the two games which we have chosen as the main ones for this Survey due to the inherent difficulty of the task he had set himself. 13.Ãb5 leads to a difficult choice for Black: 13...Àd5 seems to us the most sensible option here, leading to endgames that are not easy to assess (see Vallejo Pons-Shanava). 13.Ãc4 is an almost unexplored track. We did manage to hold the position to a draw as Black, although some crushing lines can be found here. Currently there is not enough material available on this line to draw any definite conclusions. 69


So far, no refutation of this line has been found, but if White

Another Velimirovic Attack – Part I by Luis Rodi

TsLd.tM_ jJ_SjJlJ ._.j._J_ _.j.i._. ._Bi.i._ _.n._N_. IiI_._Ii r.bQk._R The Austrian Attack is still one of the more aggressive and interesting ways to fight against the Pirc. In the Classical Variation, 5...0-0, Black has been building good defensive systems against the main line 6.Ãd3, especially with the idea of 6...Àa6 – now the principal theoretical reply. In search for solutions, White tried the interesting 6.Ãe3 and the more fundamental and more radical 6.e5. Now the natural reaction 6...Àfd7 shows better statistics for Black (White has 52,7% here, against 59,8% after the popular alternative 6...de5) and is the theoretical recommendation. For many years the theory was built on the sharp continuation 7.h4 c5 8.h5 cd4 9.hg6 dc3 10.gf7 Õf7 11.Ãc4 e6 12.Àg5, which leads to great

complications about which the theory has not yet given the last word. A Seconday Line

In this two-part Survey we will look at the move 7.Ãc4, a line regarded as secondary. As in the famous Velimirovic Attack in the Sicilian Defence, White puts the light-squared bishop on an active diagonal (Ãc4) and continues with the advance of his kingside pawns against Black’s castle. This anti-Pirc version is much more complex than the same idea in the Sicilian, because the white king will remain in the centre for a long time (in the Sicilian White puts that piece to safety by quickly castling queenside). Chaos on the Board (but Better for White)

The sharpest reply to 7.Ãc4 is 7...c5, by analogy to the 7.h4 line. It was first played by Aleksandar Matanovic in the early 1950’s, but his only follower appears to have been Aivars Gipslis. But then, after 8.e6! Àb6 9.ef7 ®h8, GM Dragoljub Velimirovic introduced the sensational 10.h4!? in 1971. In the stem game, his opponent Dusan Rajkovic did not venture to take the sacrificed piece and continued to develop with 10...Ãg4, but he was quickly punished.

Obviously, the capture 10...Àc4 is critical. The position that arises after 11.h5 Ãf5 was played in two recent games.

This leads to complex positions after 12...cd4 13.hg6 h6 14.Àe6 ©c8. The two games are spectacular and can bring a new wave of popularity to 7.Ãc4, as well as a diminishing prestige to the alternative 7...c5.

Now 13...©f8 is insufficient, as can be seen in the comments to the game Unzicker-Botterill, Hastings 1971/72. The fashionable choice is 13...Ãd7, when 14.©d2 is more enterprising (in the Game Section we will see the alternatives 14.Àf3 – Khamrakulov-Garza Marco, Utebo 2012 – and 14.Àc6, Wittmann-Nunn, Haifa ol 1976. After 14...Õc8 White has a choice between 15.Àe4!? (Wittmann-Ehlvest, Manila ol 1992) and 15.Õae1. The latter move, in the game Kholmov-Gipslis, Tashkent 1958, conceded some initiative to White. The choice between 10.h4 or 10.Ãe2/d3 is a matter of style, but I think that in a tournament game the former approach offers more practical chances to White, and in this case, Black’s defence is more difficult.

A Small White Initiative

Of course, White is not forced to give up the piece and enter into the wild complications of Velimirovic’s line. In the majority of the games (before the appearance of the above-mentioned games, I think!) the white player preferred to withdraw the threatening bishop, taking it to e2 (very interesting, meanwhile, is 10.Ãd3, a recommendation by Viktor Moskalenko in his recent book The Perfect Pirc-Modern). A critical position in this line arises after 10...cd4 11.Àd4 Àc6 12.Ãe3 Õf7 13.0-0.

The main line goes like this: 7.h4 c5 8.h5 cd4 9.hg6 dc3 10.gf7 Õf7 11.Ãc4 e6 12.Àg5, leading to great complications, but theory has not said the last word. A rela-


tively recent high-level example is 12...cb2 13.Ãb2 ©a5 14.®e2 Àf8 15.Àf7 ®f7 16.f5? (16.©d6 Àc6 was necessary, with chances for both sides) 16...Ãe5 17.Õh5 ®e8 18.fe6 Ãe6 19.Ãe6 ©b5 20.©d3 ©b2 21.©f5 ©b5 22.c4 ©b2 23.®f3 Àc6 24.©f7 ®d8 25.©f8 ®c7î Sutovsky-Ivanchuk, Khanty-Mansiysk 2011] 7...c5 [Black plays as in the main line, attacking the white pawn centre right away, but White can play differently in this case! I think that a better idea would be to take care of e6 by playing 7...Àb6 (you can see this move in Games 9 to 17 in Part II).


Velimirovic’s sacrificial idea 10.h4 deserves more practical tests. It leads to interesting games in positions that have not yet been exhausted by the theory. If Black continues with 7…c5, analogous to the 7.h4 line, he could face unexpected tactical problems, as highlighted in the Main Game Ivanisevic-Dzhumaev. But in the quiet 10.Ãe2 line, Black’s play is not sufficient for equality either. Finally, as a result of Moskalenko’s support, it is safe to predict a rise in popularity of the move 10.Ãd3. Addendum

I would like to end Part I of this series by acknowledging the collaboration of my friend and student David Borensztajn for the revision and correction of my English text! In Part II of this Survey we will take a look at the other defensive set-ups for Black. Apart from the aggressive 7...c5 there is 7...Àb6 (in my view the best way for Black) and 7...e6 (rustic and insufficient).

Black has also tried 7...e6, but I don’t think that is such a good idea (Games 18 to 20, also in Part II)] 8.e6! Àb6 9.ef7 ®h8 10.h4!? [I must confess that it is very difficult to put a sign to a move like this. White makes a bold sacrifice, laying all the cards on the table for the attack, in the best tradition of this line. The alternative, logically, is to retreat the threatened bishop, for example with 10.Ãe2 (see Games 4 to 8), a move chosen in the overwhelming majority of the games] 10...Àc4 [Of course, acceptance is the critical line. Meanwhile, in the stem game Velimirovic-Rajkovic, Skopje

Survey PU 12.9 1971, Black preferred to ignore the piece and continued his development with 10...Ãg4. In Game 3 you can see how the great attacker Dragoljub Velimirovic played this position] 11.h5 Ãf5 12.hg6 [A novelty, opening the h-file for a direct attack! A few months prior to this game, White played the interesting 12.Àg5!? in KadricMoiseenko, Prague jr 2012.

In practice it is quite difficult to defend this type of position!] 13...Ãf5 [Weaker is 13...Ãf7?! 14.Àg5 and White has a fierce attack. A sample line is 14...®g8 (but not 14...h6 15.©g4! and White wins.

T_L_.tM_ jJd._.jJ ._SlJ_._ _._J_._. ._.i.bS_ _._B_Ni. Ii._Ni.i r._Q_Rk. Dear reader, I confess that I’m not an expert of the French Defence. As White, after 1.e4 e6 2.d4 d5, I play the peaceful move 3.Àd2, as if I’m asking the opponent: ‘Please, give me a small plus and leave me alone’. However, not everything depends on us. In the past 18 months I have had to delve deep into the maze of one line of this opening variation after my opponents forced me to struggle in surrealistic positions no fewer than four times. The problems began in Norway.

In Yearbook 105 Andreas Tzermiadianos examined the ramifications after 13...Ãd7 and now 14.Õc1!. However, my opponents without exception played the move 13...Àg4. Looking in the database, we find that this is actually one of the most common black moves in this position. Emanuel Berg in particular has done well in this line. Here are his statistics from the databases (but he must have played it in rapid and blitz games, too): +4 -1 =5 (from Black’s point of view). Quite good for Black, isn’t it? I think it’s time to remedy the situation and find lines that offer White some perspective in this variation. The Main Expert

Brief information about our ‘opponent’: Emanuel Berg: 31 years of age, Swedish grandmaster, Elo fluctuates between 2550-2627. Good family man (four(!) children), modest, talkative. Only for New In Chess Yearbook readers the author managed to gain Emanuel’s confidence and received an exclusive assessment of this line from its main expert. Emanuel Berg opines: ‘This variation spawns a lot of interesting complications and is a good practical choice if Black wants to play for a win and is ready to take

Emanuel Berg

some risks. It is still too early to draw any conclusions about the variation and further games are required.’ I don’t really know how you read this, but to me it seems to be a sincere assessment. But let’s convince ourselves. 13...Àg4 strengthens Black’s control of the key point e5, opens the f-file for the rook and eyes the pawns on f2 and h2. In reply White has three plans at his disposal. Let’s divide them into three branches: 1) ‘cowardly’ 2) ‘jagged’ 3) ‘aesthetic’ The ‘Cowardly’ Replies

If you get a variation like this on the board unexpectedly, it is probably safer to apply the ‘cowardly’ version. Otherwise you 81

risk losing quickly in puzzling complications. This is why, when facing the move 13...Àg4 for the first time, I replied 14.©d2.

T_L_.tM_ jJd._.jJ ._SlJ_._ _._J_._. ._.i.bS_ _._B_Ni. Ii.qNi.i r._._Rk. Now, with careful play, this results in equality (KasparovM.Richter). A striking example of real determination to win was Emanuel’s game against Munoz Sanchez. Black intentionally went for an endgame a pawn down. This masterpiece was created at the Olympiad! We all know that reliability is appreciated in a team tournament. Please allow me to label the games Kudrin-Zhukova (14.Õe1?!) and Winsnes-Berg (14.®g2) as belonging to the ‘cowardly’ type. All the lines specified above have one thing in common: White actually didn’t fight for an advantage. The ‘Jagged’ Reply

To players who are not afraid of broken pawn chains (i.e. doubled or isolated pawns), we recommend the ‘jagged’ variation. Materialists may also like this way of playing, as White is usually an exchange up here. However, in this line you will trod mind-boggling paths where you have to find a lot of only moves. After 14.Õc1 Black strikes a blow that is typical for such structures: 14...Ãf4 15.Àf4 Õf4 16.gf4 ©f4. As always, it’s 82

extremely difficult to assess the ensuing position.

T_L_._M_ jJ_._.jJ ._S_J_._ _._J_._. ._.i.dS_ _._B_N_. Ii._.i.i _.rQ_Rk. With the queens on the board, both kings are in danger (see Brynell-Sjodin), but the white one usually more so (KokarevKosyrev). Two games by Azarov (a difficult endgame) are of interest. By the way, his victory over the variation’s ideological inspirer at the Bled Olympiad 2002 is indicative. The ‘Aesthetic’ Reply

The most popular is the ‘aesthetic’ variation. Here, too, computer analysis is required, but the difference with the previous line is considerable: 14.Ãd6 ©d6 15.Àc3 e5 16.de5.

T_L_.tM_ jJ_._.jJ ._Sd._._ _._Ji._. ._._._S_ _.nB_Ni. Ii._.i.i r._Q_Rk. Now, after general exchanges on e5, the sharpest battle starts. I advise you to pay attention to grandmaster Gleizerov’s duel with Nikoletta Lakos. The original analysis by the French Defence expert himself was published in Sahovski

Informator, Volume 76. Here I have ventured to add my own comments to the analysis. Probably, though, Houdini differs from the programs in 1999. Inappropriate modesty in White’s actions leads to equality (Kasparov-Papasimakopoulos). Nevertheless, Black more often plays the original manoeuvre 16...©h6!?. This looks dangerous because it threatens 17...Õf3, followed by 18...©h2 and mate. However, the resolute 17.h4 repels this threat, while at the same time creating a fine foothold for the knight on g5.

T_L_.tM_ jJ_._.jJ ._S_._.d _._Ji._. ._._._Si _.nB_Ni. Ii._.i._ r._Q_Rk. The game HuschenbethKurmann is of high quality. Houdini’s first lines are played almost till the end. The English grandmaster Haslinger handled the first half of his game with Berg perfectly, while in the duel Vachier Lagrave-Berg the Elo favourite failed to get an advantage. A forced exchange sacrifice took place in my game against Polivanov. Please study the attack on the black king in the Kudrin-Ryan struggle. Conclusion

This variation is halfway sound for Black, but in rapid and blitz games it is, of course, dangerous for his opponent. Even in classical tournaments it’s risky for White to go for the basic lines without special preparation.

TsLdMl.t jJ_.jJ_J ._._.sJ_ _._I_._. ._.i._._ _.n._._. Ii._.iIi r.bQkBnR We continue our journey in the labyrinth of variations in the Panov Attack. At first sight it seems that 6.cd5 creates fewer problems than 6.©b3, which we considered earlier in Yearbook 106. Quite Acceptable

It appears logical for Black to capture this pawn at once with 6...Àd5. However, we must pay some attention to the quite acceptable 6...Ãg7. With this ‘contactless’ developing move Black can usually count on full-fledged play (Alexandrov-Kasparov). However, 7.Ãb5 Àbd7 8.d6!? is more astute, trying to create chaos in the enemy camp. In this regard I recommend the strategy of the strong Russian grandmaster 88

Burmakin (game Leon HoyosBurmakin). I also include my game against Schnider. There, transposition of moves led to the same position with a wandering king. Please pay attention: in these examples Black, with the pawn on d6, uses the blockade square d5 as a ‘weapon emplacement’. A pawn sacrifice for the initiative (seen in the Olympiad encounter Godena-Jones) is less unambiguous. The Basic Plan

So we will return to the basic plan: 6...Àd5. Why should Black refuse to restore the material balance?

TsLdMl.t jJ_.jJ_J ._._._J_ _._S_._. ._.i._._ _.n._._. Ii._.iIi r.bQkBnR Now, if White plays without a plan, Black even gets some initiative (games of the author against Slaby and Milenkovic). It is better to press on the d5-point, compelling the knight to leave its active position. The line with this idea will be divided into two.

Gata Kamsky

Smooth Development

‘Frictionless development’ (as in Vysochin-Kasparov, viz. 7.Ãc4 Àb6 8.Ãb3 Ãg7) allows Black to obtain sufficient counterplay with the standard manoeuvre ...Àb8-c6-a5-c4. It is also good for him to simplify the position by means of exchanges (EhlvestKamsky). The works of Gata Kamsky always bear a ‘quality mark’. The irrelevance of an early pawn attack with an open and insecure position of one’s own king is shown in Postny’s win. The advance d4-d5, cramping the enemy, looks more ambitious. The idea is to hinder the mobility of Black’s pieces and the pawn on e7, and to use the vacant square d4. However, this is not very dangerous either. Black instantly changes the route of the

Survey CK 3.2

knight: ...Àb8-a6-c5, aspiring to counterplay again (LenicDubov). The Olympiad saw a quite titanic struggle between elite chess players (Azmaiparashvili- Morozevich), which was complicated and interesting. Other routes of the knight are also possible; see M. ZaitsevKasparov. In the structure with d4-d5 it is useful to keep in mind that usually (there are always exceptions, of course) exchanges favour Black, as his position is definitely cramped. New Ideas

There are some new ideas after 7.©b3 Àb6.

TsLdMl.t jJ_.jJ_J .s._._J_ _._._._. ._.i._._ _Qn._._. Ii._.iIi r.b.kBnR Usually White’s bishop jumps out to b5 with check. The following move order is popular: 8.Ãb5 Ãd7 9.Àf3 Ãg7 10.Àe5 0-0 11.Àd7.

Ts.d.tM_ jJ_NjJlJ .s._._J_ _B_._._. ._.i._._ _Qn._._. Ii._.iIi r.b.k._R White gets the bishop pair, which, however, is compensated for by the presence of an isolated pawn. With competent play, Black will achieve an acceptable position. There are no illustrative elite games with this line, which is why I will confine myself to several examples from my own practice, with references to other players’ games. It is possible to set up a blockade on the dark squares, hoping to exploit the cramped position of White’s light-squared bishop at some stage (Stets-Kasparov). After a queen exchange, the weakness of the isolated pawn will be felt (Inkiov-Kasparov). The direct push of the outside pawn a2-a4-a5 deserves attention; Black must respond accurately, without repeating my mistakes (Bielinsky-Kasparov). In case of an exchange on e3, White will feel some discomfort

[Black’s position is quite viable] 18.Ãf4 [Looks like a blunder, but by a miracle it doesn’t spoil White’s position! 18.c4 Ãb7] 18...Õc3 19.Ãd2 Õc7 20.Õac1 [By way of compensation for the pawn White’s rook raids into the enemy camp] 20...Õc1 21.Õc1 Ãe6 [Spoiling his own pawn structure, but solving the crucial problem of the strong bishop on b3] 22.Ãe6 fe6 23.Õc7 Àd5 24.Õa7 Ãe5 25.de5 [The situation has stabilised into approximate equality. The knight protects the pawn on b6]

because of his weak e-pawn. With the presence of oppositecoloured bishops, the pawn structure h7-g6-f7-e6 is much more reliable than h2, g2, e3, d4, isn’t it? (M.Stolz-Kasparov) Planless manoeuvres can lead to exchanges, and in the endgame the isolated pawn will become weaker and weaker (L.SchutKasparov). An interesting idea (...Àb6xd7, ...Àb8-c6) was demonstrated by Caro-Kann expert Denis Yevseev. One of the strongest blitz players in Russia treats the variation in an original manner with Ãc1-g5 (B.Savchenko-Dubov). Another master class, with the application of the frequently used manoeuvre ...Àb8-a6-c5a4, comes from Gata Kamsky. When you look at this game, please don’t forget that it was played in a rapid tournament. Conclusion

In general, one gains the impression that after 6.cd5 Black has no big problems. With a material balance he has no weaknesses, while his cramped position can be improved by exchanges. At the same time, White’s structural deficiencies (his isolated pawn) are there to stay.

Caro-Kann Defence

Advance Variation

CK 4.11 (B12)

A Sortie for the Ambitious by Krzysztof Panczyk and Jacek Ilczuk

Ts._MlSt jJ_._JjJ ._._J_._ _.jJiL_. ._.i._._ _.n.bN_. IdI_BiIi r._Qk._R The Advance Variation in the Caro-Kann Defence differs considerably from most lines in this opening. Instead of peaceful and strategic play that tends to lead up to an endgame, complicated positions arise which demand great tactical skills from both players. The early queen sally 6...©b6 leads to one such variation. In order to have any chances of obtaining an advantage in the opening, White will have to sacrifice the b2-pawn (and potentially the c2-pawn) with 7.Àc3. Black has no other choice than to accept the challenge, otherwise the early queen sally cannot be justified. In the position after 7...©b2 White has all his pieces developed against Black only his f596

bishop and the b2-queen, which is actually exposed to attacks by all of White’s pieces. If White had castled, Black’s fate would be sealed, but fortunately, he hasn’t yet. White has at his disposal two reasonable continuations: the slightly paradoxical 8.©b1 and a classical aggressive action on the queenside with 8.Àb5. NEW IN CHESS

An Aggressive Knight Sortie

The knight sortie 8.Àb5 creates an immediate threat against Black’s queen’s rook (this move is very popular, particularly among weak players) – as a matter of fact this will only gain an exchange, as the chance of getting the knight out of a8 is rather slight.

Ts._MlSt jJ_._JjJ ._._J_._ _NjJiL_. ._.i._._ _._.bN_. IdI_BiIi r._Qk._R A straightforward attempt to parry this threat with a simultaneous development of the knight by 8...Àa6 ends tragically for Black after 9.dc5! (BrochetPeyrat, Bagneux 2002). Any attempts to save the rook by a king

Sergey Karjakin

move are also doomed to failure. White has an excellent game after c2-c4 followed by opening the centre both after 8...®d8 (comments to Borst-Deidun, Email 2000) and 8...®d7 (V.Sokolov-Balta, Email 2005). White is posed much greater problems with the closure of the centre by 8...c4. This time White refrains from the simple lines that suggest themselves, and gives up the immediate 9.Àc7 (Thomas-Piankov, La Fère 2010), preferring to force the exchange of queens by 9.Õb1 and only after 9...©c2 10.©c2 Ãc2 11.Õb2 Ãa4 take the exchange with 12.Àc7 ®d7 13.Àa8 (Huschenbeth-Lenic, Chur 2010, and Dabija-A.Szabo, Email 2010), which leads to a small advantage for White. It is worth adding that after 9.Õb1 the

Survey CK 4.11

continuation 9...©a2 10.Àc7 ®d8 11.Àa8 Ãc2 deserves attention (comments to Huschenbeth-Lenic). Now after 12.Õa1 ©b2 13.©c1 a position very much like in the two previous games arises, only without the white a2-pawn. On the other hand, White rules the a-file, and the game is equal. The only chance to achieve something is a sacrifice of the queen: 12.Õb7 Ãd1 13.Õb8 ®d7 14.Ãd1, with a very unclear position, in which, however, White does not risk much (Areschenko-Jobava, Burgas 2012). A definitely better option for Black is taking another pawn: 8...Ãc2! 9.©c1 ©c1 10.Õc1 Ãg6. Now 11.dc5 ®d7 (Efremov-Cardelli, Email 2010) leads to an equal game. White has somewhat better chances of obtaining an opening advantage in the line 11.Àc7 ®d7 12.Àa8 c4 13.Àh4 Àc6 14.0-0 Ãb4 15.Àg6 hg6 16.Õb1 – however, also here Black has sufficient counterplay both after 16...b6 (DomancichCortes Olivares, Email 2008) and 16...®c8 (S.B.Hansen-Berkes, Heraklion 2007). Offering the Queen Exchange

8.©b1 looks strange at first sight.

Ts._MlSt jJ_._JjJ ._._J_._ _.jJiL_. ._.i._._ _.n.bN_. IdI_BiIi rQ_.k._R White ignores the fact that the c3-knight is unprotected. However, Black cannot accept this

‘sacrifice’, as 8...©c3 runs into 9.Ãd2, catching the queen. Here Black has two possibilities: to withdraw his queen to b4 or exchange the queens on b1. After the more rarely used 8...©b4, normal developing moves do not lead to an advantage for White, e.g. 9.dc5 or 9.0-0 (Torner Planell-Landero Luna, ICCF 2005). Fortunately, he can force the queen exchange after 9.a3! ©b1 10.Õb1. Now Black’s best move is 10...b6. Nevertheless, immediately barging in with the rook onto the seventh rank with 11.dc5 bc5 12.Õb7 gives White a small advantage. The immediate queen exchange 8...©b1 9.Õb1 is met much more often.

Ts._MlSt jJ_._JjJ ._._J_._ _.jJiL_. ._.i._._ _.n.bN_. I_I_BiIi _R_.k._R There is only one slight difference in comparison with the previous line – the position of the a-pawn (on a2 instead of a3), which is not important in this position. Now, closing the centre by 9...c4 does not allow Black to equalize. After 10.Õb7, taking another pawn with 10...Ãc2 gives a strong initiative to White and after 10...Àc6 he can count on a small edge both after the slightly strange 11.®d1 (MekhitarianVan Delft, Dieren 2010) with play on the kingside, and 11.®d2, trying to dominate on the b-file with his rooks (Inarkiev-Elianov, Astrakhan

2010). The most popular 11.Àb5 Àd8 12.Õc7 leads after 12...Ãc2 13.Àd6 Ãd6 14.ed6 Õb8 (comments to LastinKorobkov, Maikop 2008) to a small advantage for White. Still worse is 12...Õb8 13.Àd6 Ãd6 14.ed6 Õb1 15.Ãd1 Ãc2 16.®d2 Ãd1 17.Õd1 when White had the upper hand in Karjakin-Elianov, KhantyMansiysk 2010 and RattingerCardelli, Email 2010. Like in the variation with 8...©b4 Black can play 9...b6 as well. White should exchange the pawns in order to open the b-file: 10.dc5 bc5 11.Õb7. (After 11.Àb5 Black should play 11...®d8! 12.Àd6 Ãd6 13.ed6 Àd7 14.Õb7 a6 with ideas similar to those in Saenko-Gerbich, Email 2010, only with the pawn on a2 instead on a3.) Now, after 11...d4 White has chances of obtaining a small edge after 12.Àg5 (a comment to Baklan-Rasmussen, Plovdiv 2008). After 11...a6 12.Àa4 Àd7 13.®d2 White stands a little better (Voiculescu-Szabo, Email 2012). Conclusion

The classical aggressive knight sally (8.Àb5) leads to positions in which Black has sufficient counterchances to equalize. Much better looks the (at least at first sight) slightly paradoxical move 8.©b1. Here White can count on a small advantage. It is worth mentioning that the statistics in this variation are very cruel for Black – White achieves about 70%. Independently of the fact that theoretically White has only a small edge, this line seems to be very difficult to play in practical games. Therefore Black should rather decide on the continuation 6...cd4 7.Àd4 Àe7. 97

A Black Repertoire for Blitz by Alexander Ipatov

e5 Àf6 Àe4

TsLdMl.t jJjJ_JjJ ._._._._ _._.n._. ._._S_._ _._._._. IiIi.iIi rNbQkB_R Nowadays blitz and rapid tournaments are organized no less frequently than classical events, so it’s wise to have a different opening repertoire depending on the time-control. In this Survey I’d like to examine a rare line in the Petroff Defence: 3...Àe4. It was already covered by Or

Cohen in his article ‘Petroff for Beginners’ a few years ago in Secrets of Opening Surprises no. 10, but the current Survey covers more variations thanks to recent games which have been played since. Symmetrical

Instead of playing the normal move 3...d6, Black grabs the pawn on e4 immediately, allowing White to win a pawn after 4.©e2 ©e7 5.©e4 d6.

TsL_Ml.t jJj.dJjJ ._.j._._ _._.n._. ._._Q_._ _._._._. IiIi.iIi rNb.kB_R Now White has two main options: A) 6.f4 (a rare move) B) 6.d4 (the main continuation) Let’s analyse them one by one.


A Rare Move

Alexander Ipatov


After 6.f4, 6...de5 7.fe5 f5! must be played. In my first game with this line, I didn’t know all these nuances. I made a mistake and played 7...f6, which is supposed to be an inaccuracy. After that White got the upper hand; see the

game Edouard-Ipatov, Andorra Open 2010. However, after the correct 7...f5 I haven’t been able to find a clear path to an advantage for White.

TsL_Ml.t jJj.d.jJ ._._._._ _._.iJ_. ._._Q_._ _._._._. IiIi._Ii rNb.kB_R White has two continuations so far: the positional 8.©e3 and the aggressive 8.©f4. In the positions which arise after 8.©e3 Black is under slight pressure, but he should be able to equalize with precise play. For more details, see the blitz game Aveskulov-Ipatov, 2010. On the other hand, after 8.©f4 the game turns into a real battle, in which Black has excellent chances to get an advantage despite White managing to keep an extra pawn. As just one game with 8.©f4 has been played so far, I’m glad to share my own analysis of this move. The Main Move

Anyway, the main move is considered to be 6.d4. It looks more logical, as White doesn’t weaken his kingside (like after 6.f4) and

Survey RG 3.1

at the same time opens the diagonal for his queen’s bishop. Black must take: 6...de5, and here we are at a little crossroads. With what piece should White take on e5? B1) 7.©e5 leads to a queen exchange and a slight advantage for White in the endgame. White must continue with 9.Ãe3 or 9.Àc3 in order to fight for the opening advantage – see G. Sergeev-Afromeev, Tula 2005. B2) 7.de5 Àc6, and here we arrive at the main crossroads in this Survey.

T_L_Ml.t jJj.dJjJ ._S_._._ _._.i._. ._._Q_._ _._._._. IiI_.iIi rNb.kB_R White’s options are manifold: B21) 8.f4, leading to very interesting positions with a lot of struggle. It’s examined in the games Short-Ipatov and IpatovYilmaz.

B22) 8.Ãf4 promises Black nice play, as witness the annotations to the game Ye Jiangchuan-Ni Hua. B23) 8.Ãb5 branches after 8...Ãd7 into: B231) 9.0-0, where Black is doing fine, and B232) 9.Àc3, with which White might get an advantage if he knows what to do until move 20. The critical game is Naiditsch-Volkmann, Istanbul 2003. The main move for Black is considered to be 9...©b4, but recently an interesting game was played with 9...0-0-0. Check out the encounter Papp-Volkmann, Austria Bundesliga 2011/12, in the Game Section below for more details. Returning the Pawn

However, I think there is another line in which White can get a positional advantage with no risk. In order to get this, White must give back the pawn: B24) 8.Àc3! Black must accept the offer, and after 8...©e5 9.©e5 Àe5 10.Ãf4! Ãd6 11.Ãg3 Ãd7 12.Àe4 0-0-0 13.Àd6 cd6 14.0-0-0 Ãc6 15.f3

I’ve played three classical games with 3...Àe4, and only my third opponent found a way to get an advantage, whereas my two first 2600+ rivals failed to find out what to do! In general, I wouldn’t suggest going for this line except in blitz and rapid tournaments. But against an unprepared opponent it might be worth a try! And, of course, it is supposed to be a strong weapon in blitz games. This I can vouch for from my own experience :)

Is the Fianchetto Set-up Comfortable against the 5.d3 System? by Mihail Marin e4 Àf3 Ãb5 Ãa4 d3 c3

e5 Àc6 a6 Àf6 d6 g6

T_LdMl.t _Jj._J_J J_Sj.sJ_ _._.j._. B_._I_._ _.iI_N_. Ii._.iIi rNbQk._R As a great fan of the Open Variation of the Ruy Lopez in the late 1980s and early 1990s, I needed to be concerned about the modest-looking yet venomous d2-d3 systems in only one version, on the fifth move. At that stage, Black has not committed his king’s bishop yet, which allows him to switch to the fianchetto set-up with 5...d6, soon followed by ...g7-g6. During the 1988 Olympiad, I won a nice game in which I conceived over-the-board what I considered to be a wise plan. I annotated the game for Yearbook 12 and in the following years I won several other games with the same idea. You will find the pleasant side of my experience with this line in the notes to Reyes-Marin in the Game Section. 112


My basic plan was inspired by Romanishin’s treatment of the Chigorin blocked variations: Black meets the manoeuvre Àbd2-f1 with ...g7-g6 and ...Àh5, in order to meet Àf1-g3 with the active ...Àh5-f4. There is a slight abstract problem for Black in the 5.d3 line, though. Unlike in the Romanishin line, White has not defined his intentions in the centre yet. Concretely, my idea was put in serious doubt in the game Lopez Martinez-Marin. My opponent’s move order caused me to lose stability in the centre. Despite my nice memories, I had to admit that this was a logical punishment after all; Black has been toying around too much in the opening! Some Refinement

I did not feel like giving up the fianchetto, though, especially since by that time I had become a fervent adept of the Pirc. The set-up only needed some refinement, I thought. Black did not need the knight manoeuvre at all, but there was also a question about the opportunity of ...Ãd7. After all, White does not threaten Ãxc6(+) at all and in one of the games below, play transposes from the anti-Berlin move order (3...Àf6 4.d3 d6), where White meets a later ...a7-a6 with Ãb5-a4 anyway!

By delaying the bishop’s development, Black keeps the possibility of switching to a more active set-up than the Steinitz Defence Deferred (as happened in all my earlier games). The main line goes: 5...d6 6.c3 g6 7.0-0 Ãg7 8.Àbd2 0-0 9.Õe1.

T_Ld.tM_ _Jj._JlJ J_Sj.sJ_ _._.j._. B_._I_._ _.iI_N_. Ii.n.iIi r.bQr.k. Several reasonable moves have been tried here, but I find 9...b5 to be the most natural of them. White can choose between

Survey RL 12.3

10.Ãb3, allowing a transposition to a Chigorin type of structure after 10...Àa5 11.Ãc2 c5, and 10.Ãc2, when sooner or later Black will probably switch to a Breyer set-up with ...Àc6b8-d7. In both cases, if White displays central activity with d3-d4, the bishop’s development to g7 without the usual loss of tempi (...Ãf8-e7, ...0-0, ...Õfe8, ...Ãf8, etc.) is most welcome. The latter circumstance is especially relevant in the Chigorin set-up, where 12.d4 is simply premature; see V. Rasik-Adams. The developing 12.Àf1 is better.

T_Ld.tM_ _._._JlJ J_.j.sJ_ sJj.j._. ._._I_._ _.iI_N_. IiB_.iIi r.bQrNk. White prepares d3-d4, but also creates the threat of Ãg5, fighting for the d5-square. It is worth mentioning that in the normal Chigorin lines, Ãg5 would hardly be a threat, because Black could react with ...Àd7 or ...Àh5. If Black chooses to keep the possibility of transposing to the game above in case of d3-d4 by playing 12...Õe8, 13.Ãg5 may cause some slight trouble, as revealed in the notes to JansaHaba. Since Black has gained several tempi so far, he can spend one on the prophylactic 12...h6. The good news is that the occupation of the centre with 13.d4 remains harmless, as in the game Zhukhovitsky-Sokolsky. Or if 13.Àg3 Õe8, Black’s position is absolutely fine, as in A.Rombaldoni-Melkumyan.

Looking for an Advantage

Since 10.Ãb3 does not seem to cause Black any problems, White should look for (at least a tiny) advantage with 10.Ãc2.

T_Ld.tM_ _.j._JlJ J_Sj.sJ_ _J_.j._. ._._I_._ _.iI_N_. IiBn.iIi r.bQr.k. Although this seems to offer Black a wider choice, White has his trumps, too. With the black king’s bishop away from the a3-f8 diagonal, plans based on b2-b4, a2-a4 and Àd2-b3 may be effective. For instance, the hurried 10...d5 weakens the c5square at once, leaving White with pleasant play, as in Akopian-Giorgadze. Black is better advised to keep neutrality for a while with developing moves like ...Ãb7 and ...Õe8, in the spirit of the Zaitsev Variation. One popular continuation is 10...Ãb7 11.Àf1 Õe8 12.Àg3.

T_.dT_M_ _Lj._JlJ J_Sj.sJ_ _J_.j._. ._._I_._ _.iI_Nn. IiB_.iIi r.bQr.k. The slightly unusual 12...©d7, connecting the rooks, is entirely playable, as in VujosevicRomanishin, but 12...Àb8 13.d4 Àbd7, transposing to Charbonneau-Alexandrov (featuring the

anti-Berlin move order), may be more flexible. I believe that the natural 11.Àf1 is not the best. White should use his knight on the queenside, starting with 11.a4, followed by b2-b4, as in NepomniachtchiKamsky. The same may happen if Black starts the Breyer knight manoeuvre at once with 10...Àb8, as in FedorchukGrabarczyk. In these lines, Black does not seem to be in great danger, but White’s position remains more pleasant. A Change in Move Order

However, Black can sidestep this problem by changing the move order slightly. He can delay ...b7-b5 until the d2-knight has moved by playing 9...Õe8.

T_LdT_M_ _Jj._JlJ J_Sj.sJ_ _._.j._. B_._I_._ _.iI_N_. Ii.n.iIi r.bQr.k. After 10.Àf1 b5 the game would transpose to some of the lines above. White’s best chance is 11.Ãb3, hoping for a transposition to Jansa-Haba after 11...Àa5 12.Ãc2 c5 13.Ãg5, but Black can be tricky until the end with 11...h6, when nothing really can stop him from switching to a favourable form of the Chigorin. A Rapid Kingside Attack

Things have been looking comfortable for Black so far, but one important issue remains: the rapid kingside attack based on the early knight transfer to f1. The most dangerous way to carry 113

out this plan is 7.Ãg5 Ãg7 8.Àbd2 and if 8...h6 9.Ãh4 0-0, then 10.Àf1.

10...Àe7, unpinning the brother knight and preparing ...c7-c6 and ...d6-d5. A few moves later, I faced the nasty surprise 13.Ãf6!, followed by 14.h4, with a certain white initiative. In my notes, I have indicated a possible way to equalize even after that, but my main conclusion was that ...Àh5, played as soon as possible, was recommendable. Which I duly did in Harikrishna-Marin, played a few years later, but once again I got into (even deeper) trouble. This time, there was no lucky save for me, but objectively Black should be fine after the opening.

The reader may understand that my feelings about Black’s setup examined in this Survey are mixed. After an initial incredibly favourable experience, things got cloudier for me. I believe that the analysis provided here proves that the variation is playable for Black, but my continuous problems may suggest that in practice White’s play may be slightly easier. In fact, this is the main idea of 5.d3; rather than fighting for an objective advantage, White hopes to get this type of position. Carlsen-style!

A Concrete Reason for 5…Àa5! by Jeroen Bosch

T_LdM_St jJjJlJjJ ._._._._ s._._._. ._BjI_._ _.i._N_. Ii._.iIi rNbQk._R If there is one dictum of Tarrasch’s that all chess players will be familiar with, then it is surely: ‘knights on the rim are dim’. While this is a useful general rule for teaching beginners how to best position their knights, it has often been ridiculed by chess authors (including myself) to demonstrate Tarrasch’s inflexibility and, more particularly, the concrete nature of chess. Indeed, sometimes the best square for a knight is precisely on the edge of the board, and nobody should have any inhibitions about placing it there. John Watson has noted that ‘contemporary knights live on the edge’ in his well-known Modern Chess Strategy, and in the course of the SOS opening series I have personally written repeatedly on opening lines 120

where knights are deliberately placed on the a- or h-file (for example the Grünfeld with 5.Àa4, or the Budapest Gambit line with 5.Àh3). I actually suspect that Tarrasch himself was not as inflexible about his rule as he has been made out to be: he did after all play Chigorin’s knight manoeuvre (…Àa5) in the Ruy Lopez when he challenged Lasker for the World Championship title in 1908. The Hungarian Defence or the Scotch Gambit?

In this opening Survey we will look at an ancient line in which placing the knight on the edge of the board is, in my opinion, actually the only correct way to proceed. After 1.e4 e5 2.Àf3 Àc6 3.Ãc4 Black is not obliged to enter the popular Giuoco Piano or the Two Knights Defence, as there is the slightly passive alternative 3...Ãe7 (the Hungarian Defence) to consider. Hort, Spassky and Petrosian have on occasion used this defence, but at different stages in his career Smyslov has been the most consistent practitioner of 3...Ãe7. After the logical 4.d4 Black can either keep the centre with 4...d6 or surrender his claim with 4...ed4 to aim for fast development. Against the latter, White most often takes back on d4, but he has a dangerous alternative in 5.c3. Now this position can actu-

ally also arise via the so-called Scotch Gambit: 1.e4 e5 2.Àf3 Àc6 3.d4 ed4 4.Ãc4 and now 4...Ãe7!? (usually condemned or neglected by the theory) 5.c3. What is Black’s best move? Why is 5.c3 so dangerous? Well, just see what happens when Black accepts the Greek gift: 5...dc3 is met by 6.©d5!.

this is actually a bad, and I presume often emotional, decision, since Black can play on (and sometimes even wins!) with 6...Àh6 7.Ãh6 0-0!. See a juvenile win of present-day grandmaster Jan Smeets (SmeetsHoek, Hengelo 1994) for details on this, and the brief notes on fifth move alternatives. Moves like 5...Àf6 6.e5 and 5...d6 6.©b3 are not particularly great either. However, perhaps you have guessed Black’s best reply by now: it is 5...Àa5!

I would not want to convey the message that this knight move is a modern discovery. On the contrary, the stem game (according to the New In Chess database) is Zukertort-Mayet, Berlin 1868! So, if you like, very much in the day and age of Tarrasch, who was born in Breslau in 1862. Furthermore, my edition of ECO quite relevantly cites an analysis of Mikhail Chigorin following 5...Àa5 6.©d4 Àc4 7.©c4 Àf6 8.e5 d5! 9.©a4 Àd7,

With this analysis, the source of which is rather unclear to me, we come to the crux of the matter. What should White do after 5...Àa5 ? Should he acquiesce to Black’s strategy and take back on d4, when Black’s bishop pair (and particularly the absence of White’s dangerous attacking bishop) will always promise Black an equal game? Or should he withdraw his bishop and preserve it at the cost of a pawn? For after 6.Ãd3 or 6.Ãe2 Black will take on c3, when White certainly has compensation; but Black will no longer be blown off the board.

By Way of Conclusion

Black should place his knight on the edge of the board after 5.c3 with 5...Àa5!, so much is clear. How White next wants to proceed is to some extent a matter of taste. The game is about equal after 6.©d4. White obtains barely sufficient compensation for the pawn after 6.Ãd3 dc3 (the bishop is blocking the d-file), so this should be avoided. However, after 6.Ãe2 dc3 White does obtain compensation in the form of pressure along the open c- and d-files (in much the same way as he does in the Morra Gambit in the Sicilian). Objectively, play should be dynamically equal, but grandmasters have been willing to enter this position as White. Personally, I would either opt for the pawn sacrifice with 6.Ãe2, or avoid 5.c3 altogether. Why play an equal (although admittedly interesting enough) position after 5.c3 Àa5 6.©d4 when you can also play a slightly better position with the simple 5.Àd4 ?

In the final months of the year 2012, two local masters have succumbed at tournament praxis in resulting endings. One particular way to bore the life out of one’s skull is the line that goes 8...cd5 9.0-0 0-0 10.Ãg5 c6 11.©f3 h6 12.©f6 gf6 13.Àe2 Ãd6 14.Àd4 c5 15.Àf5 Ãf5 16.Ãf5, with drudgery to follow. OK, that’s a bit extreme... but I’m sure you get the picture. In the meantime Kramnik’s 10.h3 does not make things easier for Black, as explained by Glenn Flear in Yearbook 105. An Indelible Mark

Russian GM Viktor Varavin arrived in Singapore in 2004 to coach for two years plus and left an indelible mark on his students with enterprising, hyper-aggressive chess. In particular, his wards have achieved much success with the Ãc4 Sicilian Najdorf/Sozin and the line given above, which I have christened ‘Varavin’s Vaccine’. On the surface, Black decides not to contest the centre with ...d7-d5 and nudges the d-pawn one square to restrain the white centre. However, Varavin has a more insidious idea: launching an all-out kingside attack by hurling Black’s h- and g-pawns forward.

Varavin’s students carried his concept one step further in the 9.0-0 line, where they also play 9...Ãe6, waiting for White to play the logical-looking 10.Ãg5 before rushing the h- and g-pawns forward. I prefer to play Jan Pinski’s recommendation of 8...Àg4!, which, if not checked, will be followed by the primary school mating attempt ...©h4.

pawn structure intact. However, it does not put pressure on Black, who nevertheless can play ...Àg4 and follow up with ...Àe5/...©h4 ideas, Tschepurnoff-Treybal.

I have divided the material as follows: A) White goes for swift development with 8.0-0, allowing 8...Àg4 – as well as 8.h3 Àd7 (as it transposes to certain lines in the 8.0-0 Àd7 variation); B) The standard Four Knights pin 8.Ãg5, invoking Black’s pawn storm; C) The safe 8.Ãd2, keeping the pawn structure intact.

White can prevent the black knight from getting frisky on g4 with the prophylactic 8.h3, but this does not stop Black from reaching his desired set-up with 8...Àd7, intending 9...Àe5. Black has to be careful about grabbing e4 in some lines (Nilsson-Engman). Black has to play carefully when White eschews the bishop pair and plays for quick development and a kingside advance with f4-f5. Black has to make sure he has sufficient central counterplay to parry White’s kingside intentions; see J.SanchezKosten. Black can throw a spanner in the works with an early 10... Ãc5, as demonstrated by enterprising Ukrainian-Slovenian grandmaster Adrian Mikhalchisin in Rogulj-Mikhalchishin.

Swift Development

The Standard Four Knights Pin

German grandmaster Arkadij Naiditsch takes no prisoners when he is allowed to swing his queen to h4, and he pummels down the h-file to win in 23 moves: see Burg-Naiditsch. After 8.0-0 Àg4 White can choose to keep his two bishops with 9.h3 Àe5 10.Ãe2, but after 10...©h4 the e4-pawn is put under pressure. Trabert tried a queen trade but got ground down after an erroneous minor piece trade in the game TrabertKarpatchev. In a penultimate money-round game (winner will be assured of 3rd place minimum), my opponent protected h2 with 9.Ãf4. I went for the Varavin-like 9...g5!? and White deflected my pseudo-attack adroitly. However, the time taken to work out the lines took its toll. Black can also equalize with the sensible but less adventurous 9...©f6! (Wee Chun Jie-Tay).

Varavin left his king in the centre guarded by an arcane pawn mass after hurling forth his h- and g-pawns. Fittingly, although he was material down, those pawns helped him to draw, as the white king got hemmed in on the back rank (Frolov-Varavin). Black tried to match tactical blows by meeting the h-/g-pawn storm with e4-e5, but got outgunned instead in NovkovicOzturk. One issue in this variation is that Black has to play extremely actively to prevent White from consolidating. Black’s hesitation in the next game allowed White to anchor his knight on e3, which nullified Black’s assault plans and White could continue play on the queenside without worries; Kulicov-Khudyakov.

I hope this article will be an effective vaccine and inject some excitement in the sleepy Scotch Four Knights! I believe, as an opening philosophy, that this line is sound.

Comparing the 7...d6 Scotch Four Knights line to both Ruy Lopez variations, in our line White exerts less pressure on the centre and hence is less likely to play the e4-e5 break anytime soon, as Kasparov did against Short in the Modern Steinitz line in the 1993 PCA World Champi-

QO 11.4 (D35)

Keeping the Bishops on the Board by Alexander Finkel

d4 c4 Àc3 cd5 e4 bc3 a3

d5 e6 Àf6 Àd5 Àc3 c5

TsLdMl.t jJ_._JjJ ._._J_._ _.j._._. ._.iI_._ i.i._._. ._._.iIi r.bQkBnR The line presented in this Survey lies somewhere on the verge of the Semi-Tarrasch and shares many similarities with the Petrosian Variation of the Queen’s Indian Defence. If you compare one of the most critical lines of the Petrosian QID, which can be characterized by the following sequence: 1.d4 Àf6 2.c4 e6 3.Àf3 b6 4.a3 Ãb7 5.Àc3 d5 6.cd5 Àd5 7.©c2 Àc3 8.bc3 Ãe7 9.e4 0-0 10.Ãd3 c5 11.0-0, to the positions arising after 7.a3 Ãe7 8.Àf3 0-0 9.Ãd3 Àc6, the similarity is more than obvious – while after 7.Àf3 cd4 8.cd4 Ãb4 we just end up in the most popular line of the SemiTarrasch. However, these kinds of transpositions are rather customary for

many theoretical lines, so we shouldn’t be surprised by this mere fact, but rather try to figure out how these tiny differences in the move orders (and/or positions of the pieces on the board) influence the plans of the sides under the particular circumstances. Kramnik’s Signature

Since this variation (4...Àd5) was used by Kramnik in London 2013, it is more than reasonable to assume that: (a) it had been scrutinized by his team to a level which only very few can match and approved for usage following that scrutiny; and (b) Black is doing OK at the end of the day! Fortunately I had no intention to dig that deep to reveal the ultimate truth with respect to the evaluation of this line, nor do I purport to give recommendations to the top grandmasters on the most effective ways to play it... in any case it is logical to assume that the main efforts of Kramnik’s team were directed towards 7.Àf3.

years, 7.a3 was very successfully advocated by the (Belo-)Russian grandmaster Alexandrov, but it remains a sideline which is yet to transform into something more meaningful. After 7.a3 Black may choose between three different set-ups, but it seems that 7...cd4 8.cd4 e5, used by Kramnik, is the most crucial direction, as otherwise (that is, if Black refrains from 8...e5) Black’s task of equalizing is far from easy.

A Meaningful Sideline

Straightforward and Good?

The idea of playing 7.a3!? is by no means new. It’s been tried occasionally through the 1950s and 1960s, but just as in the recent years it was no real alternative to 7.Àf3, with which White switches to the well-known lines of the Semi-Tarrasch. In recent

Kramnik’s choice of the line 7...cd4 8.cd4 e5!? speaks for itself and rates it above other continuations, but it should be emphasized that the line is strictly for those who are willing to play for equality, as it’s just not suitable to pay for a win

(White enjoys a symbolic edge after almost every move and has a wide range of options ‘to kill the game’, should he decide to do so).

TsLdMl.t jJ_._JjJ ._._._._ _._.j._. ._.iI_._ i._._._. ._._.iIi r.bQkBnR At this point of time there is not enough study material to rely on, but one obvious conclusion that can be drawn from three top games facing 9.Àf3 ed4 10.©d4 ©d4 11.Àd4 is that Black has excellent chances to hold the

game against Rausis back in 2005.

TsLdMl.t jJ_._JjJ ._._._._ _._._._. ._BjI_._ i._._N_. ._._.iIi r.bQk._R After a first-hand look it seems that the ensuing position is also very close to equality. Nevertheless, it clearly requires more indepth investigation... And, just to state the obvious, 9.d5 can hardly be regarded as an attempt to fight for an opening advantage. Depriving White of Castling


In case Black is inclined to take his chances in the complex struggle, he may consider opting for 7...Ãe7 8.Àf3 0-0 9.Ãd3 Àc6 10.Ãb2 cd4 11.cd4 ©a5,

ensuing position after both 11...Ãc5, which has been tried by Roiz and Naiditsch (following the game Svidler-Kramnik), and 11...Ãe7, played by Kramnik. All commentators stressed that White should be looking for an advantage with 10.Ãc4, as tried by Alexey Alexandrov in his 136

White’s rook is usually brought into play via the h3square by means of h2-h4, followed by Õh3-g3, while the king goes to g1. Although it takes some time to execute all this, it is

not easy for Black to launch counterplay on the queenside in the meantime, so White seems to enjoy better chances in the forthcoming struggle. The games Vitiugov-Khalifman, LafuenteLopez Martinez and BareevHracek reveal the dangers of this line for Black. Solid but Passive

Another possible way for Black to treat this line is just to stick to the most typical developing scheme one can think of: after 7...Ãe7 8.Àf3 0-0, the lightsquared bishop is developed to b7, while the knight may come to c6 or to f6 via d7 (as often happens in the Petrosian QID), the queen is put on c7 and the rooks come to c8 and d8. The problem with this set-up is that Black is struggling to find active counterplay. However, his pieces are very comfortably placed, so if White overextends at the kingside or in the centre, Black is ready to strike back once he is offered a chance. Conclusion

Our topical 7.a3!? appears to be a very interesting option for White to use to deviate from the classical Semi-Tarrasch. In comparison to the Semi-Tarrasch, the presence of the dark-squared bishops on the board clearly favours White due to the increase in the attacking potential of his pieces, while Black’s bishop on e7 is slightly out of play. However, the waste of an important tempo in the opening allows Black to throw in 7...cd4 8.cd4 e5, with further simplifications, which reduces White’s winning chances to a minimum, unless he picks up the gauntlet and plays for the initiative by 9.Àf3 ed4 10.Ãc4, which leads to rather unclear play.

As often happens in this line White has got a strong passer on the dfile. Try to find a way to promote it. (solution on page 249)

How should White respond to this sudden and rather unexpected queen switch? (solution on page 249)

White’s king is stuck in the centre, but it’s not clear how to exploit this. Can Black take the pawn on a3 and survive? (solution on page 249)

TsLdMl.t _._.jJ_J J_J_.sJ_ _JiJ_._. _JiJ___. ._.i._._ _.n.iN_. Ii._.iIi r.bQkB_R The aggressive 6.c5 is still a popular guest in top-level tournaments. In previous Yearbooks there have already been numerous publications on it: in Yearbook 75 the authors of this article analysed it, in Yearbook 85 Bologan wrote an interesting article, and Finkel’s notes were published in Yearbook 87. We will certainly not repeat those, except that in our notes we will mention those games which have already been annotated in the previous issues. White gets a huge space advantage on the queenside. The pressure can be increased by a2-a4, followed by the opening of the a-file, and sometimes a positional piece sacrifice on b5 is possible. If the centre is opened, the c6-pawn may become

vulnerable. Black’s hopes are founded on the central breakthrough ...e6-e5, and sometimes the white c5-pawn becomes a weakness. Black has a lot of possibilities, but it is clear that he will have to abandon his passivity quickly. The Fianchetto

In Part I we will take a look at 6...g6, fianchettoing the bishop and preparing the central push ...e6-e5. In this way, the diagonal of the light-squared bishop remains open, and Black has an extra possibility of ...Àfd7. 7.Àe5 Ãg7 is the main line.

TsLdM_.t _._.jJlJ J_J_.sJ_ _JiJn._. ._.i._._ _.n.i._. Ii._.iIi r.bQkB_R Now White strengthened his knight’s position with 8.f4 in Movsesian-Wang Yue, Istanbul ol 2012. The game went as follows: 8...a5 9.Ãe2,and now Black decided to blockade the light squares on the kingside by 9...h5. This strategy worked well in the game, but White’s play can be easily improved on; see the notes. 9.Ãd3 Ãf5 adopts the

same method of taking control of the light squares. In Gelfand-Wang Yue, Medias 2010, Black simply finished his development without any concrete idea and found himself in a very passive position after 9...©c7 10.0-0 0-0 11.a3 Ãe6 12.Ãf3 Àbd7 13.Àd3! h6 14.g4 Àh7 15.h3 f5 16.g5. Gelfand created a masterpiece on the theme of how to break through a passive but well-defended position. Certainly Black’s play was far from perfect; he can improve with 13...Ãf5 for example. Another possible improvement was shown in Caruana-Giri, Wijk aan Zee 2012: 10...h5, with the same blockading strategy as before. Here after 11.h3 Ãf5 12.Ãd2 Àbd7 13.Ãf3 we reach the critical position, which requires further analysis. 141

More Flexible

If White is not happy with the previous blockading positions, he can start with the flexible 8.Ãe2. Play may continue: 8...Àfd7 9.f4 Àe5 10.fe5 f6 11.ef6 ef6 12.e4!, with the positional pawn sacrifice 12...b4 13.Àa4 de4 (Elianov-I.Sokolov, Sarajevo 2009) and now 14.©b3! can be suggested, with nice compensation for the sacrificed material. The immediate 7...Àfd7 may lead to similar positions after

8.f4 Àe5 9.fe5 f6 10.ef6 ef6 11.e4!. Therefore, in our Illustrative Game Rapport-Movsesian, Wijk aan Zee 2013, Black wanted to improve on the previous encounter with 10...0-0 (instead of 10...f6). The point is that after 11.0-0 he is not forced to transpose to the previous game by 11...f6, but there is a strong prophylactic move: 11...Õa7!. Although the brilliant new Hungarian talent won the game in an impressive way, things are far from clear here; see his notes!

6...g6 followed by ...Ãg7 is logical way to develop the bishop. Now White usually plays 7.Àe5 followed by f2-f4, gaining space and stopping Black’s liberating thrust ...e7-e5. However, Black gets some counterplay on the light squares in return. In Part II of this mini-series we will take a look at the other defensive set-ups for Black: 6...Ãg4, 6...Ãf5 and 6...Àbd7.

T_Ld.tM_ _J_S_JjJ J_JlJs._ _._J_._. ._Ii._._ _In.iN_. I_Q_BiIi r.b.k._R Several months ago, during the Serbian team championship, I faced this interesting line in the Slav Defence against GM Ivan Ivanisevic. Obviously, one of the ideas behind 8...a6 is to just postpone 8...e5 and thereby avoid 9.cd5 cd5 10.Àb5. I think this is a very interesting and playable line for Black, but somehow it seems to have been somewhat forgotten at top level. Since the famous game PortischKasparov, Dubai Olympiad 1986, White continued with 10.cd5 after 8...a6 9.0-0 (or 9.Ãb2) 9...e5 in almost all games, leading to positions in which Black has an isolated pawn. To tell you the truth, I was not sure during the game

whether or not this was the best continuation for White. I don’t really like such a set-up, in which Black has the option of using open files and diagonals, gaining an important tempo thanks to the exposed queen on the c-file. I would like to mention one important fact in this line. Chess legend GM Portisch has some experience with it, having faced it three times (once he played it himself as Black). Finally, in 1998, in the game PortischPrasad, he switched to 10.de5!?, a move which I think deserves serious attention. I have done some investigation into this line recently, and this is the right time to share it with the Yearbook readership. A Suggested Line

10.de5!? Àe5 has not been a very popular continuation so far, but it deserves serious attention.

White. The important difference, however, is that with the pawn on a6 Black’s queenside has a few weaknesses, particularly the b6and c5-squares, which could be exploited in the long run. At least, White doesn’t have to worry about open files and diagonals that allow Black sufficient counterplay. I think the games Portisch-Prasad and AnticIvanisevic give us good material for a deeper study of this line. Playing against the Isolated d-Pawn

After 9.0-0 e5, the main line goes 10.cd5 cd5 11.de5 Àe5 12.Ãb2 Ãe6. 12...Ãg4, instead of 12...Ãe6, is also possible, of course, as seen in the games Leitao-D.Mastrovasilis and Fridman-Sandipan, but I have to admit that I am not impressed 147

with this set-up. Besides, many pieces have been exchanged, which is not Black’s goal, as it reduces his activity and dynamic options. White can increase the pressure on the isolated pawn without risk. So let’s get back to 12...Ãe6.

The most common line is 13.Õac1, when the most logical reply is 13...Õc8. From the game Portisch-Kasparov to the most recent game Shulman-Hess, Black has proved that he has

enough active possibilities here. As mentioned above, I believe that White has no advantage, even in the most popular continuation. Other Options

After 8...a6, White has also tried the interesting 9.e4, as in Sandipan-Evseev.

Another interesting attempt after 8...a6 is 9.Ãb2 (MoskalenkoGonzalez De La Torre). White is trying to develop further before castling. In both of the aforementioned games, the white king can become quite exposed, and Black has a few tactical options at his disposal. Postponing castling is not advantageous at all for White, I think. Conclusion

In modern chess it is very difficult to give final definitions and conclusions about a position.The impression is that Black does have full equality in the main line. It is up to the top grandmasters to give the final verdict on this variation. Practice is very important for the development of any variation. The ball is in White’s court, but until we get a final answer from top-level players, I think Yearbook readers, chess lovers and professionals can try the plan I have suggested for White here.

T_.dMl.t jJjL_JjJ ._._Js._ s._._._. ._Qi._._ _._._Ni. Ii._IiBi rNb.k._R Although computers are gaining more and more popularity in chess and of course in the analyses of the opening lines, our experience is that the development

of a variation is often based on a fashion or on personal taste. In our present article we would like to discuss a line that has been played before – with black – by strong players like World Champions Karpov and Topalov, but for some reason never gained real popularity and reputation. It is true that in the line 4...dc4 5.Ãg2 Àc6, apart from the main move 6.©a4, White can play 6.0-0 (this move allows 6...Õb8), but after 6.©a4 Ãd7 the moves 7.©c4 Àa5 seem forced and we can reach the starting position of our Survey, given above. In the diagram position White has the sideline 8.©c3, which can be answered by 8...Àd5! (and next Black can continue his standard play with ...c7-c5), and the two principled queen moves 8.©c2 and 8.©d3.


Not So Easy

Davit Shengelia


The weak side of the move 8.©c2 is that White’s queen can be a target of Black’s usual antiCatalan play with ...Õc8 and ...c7-c5. But things are not so easy and we should not underestimate the queen’s retreat to c2, as was seen in the game GiriMeijers, where, after 8.©c2 Õc8, the young and highestrated Dutch player tried 9.Àe5 and – mainly due to mistakes by his opponent – established a very good position right after the opening.

The other try for White to avoid the main lines in the 8.©c2 variation was played in the game Buhmann-Shengelia, where White played 8.©c2 Õc8 9.Àc3 c5 10.dc5 (instead of the main move 10.0-0). Here Black played originally and well; he achieved a promising position and later won in the sharp tactical battle. The main tabiya position of the line 8.©c2 Õc8 9.Àc3 c5 10.0-0 appears in the following diagram:

._TdMl.t jJ_L_JjJ ._._Js._ s.j._._. ._.i._._ _.n._Ni. IiQ_IiBi r.b._Rk. In the game Seres-Eperjesi, Black played the direct move 10...b5!?, and after 11.dc5 Ãc5 12.©d3 b4 13.Àe4 Àe4 Black was very close to equality. In the game Paragua-Bitoon, Black played another classical set-up with 10...cd4 11.Àd4 Ãc5, but after the strong moves 12.Àb3! Ãa4 13.Ãg5! White had the better chances. Probably the best play from Black’s side was demonstrated in the game EbnerFröwis, where Black played

Survey CA 3.1

10...cd4 11.Àd4, and now 11...©b6. The young Austrian International Master showed convincing play with black in the line 12.0-0 Ãc5 13.e3 0-0, where Black has comfortable equality. The Harmonious Retreat

It seems that the best option for White on move eight is the other queen retreat: 8.©d3. After this move White can harmoniously continue his development and has chances of a small plus. Here Black mainly continues his queenside play with 8...c5 (Black can play 8...c5 at once here, without preparation. In the line with 8.©c2 Black should play the preparatory move 8...Õc8 first.)

T_.dMl.t jJ_L_JjJ ._._Js._ s.j._._. ._.i._._ _._Q_Ni. Ii._IiBi rNb.k._R Here, in the relatively old game D. Gurevich-H. Olafsson, White played 9.Àe5, but after 9...Àc6! 10.Àc6 Ãc6 11.Ãc6 bc6 12.©f3 ©d5 13.dc5 the natural move 13...Ãc5 is Black’s best bet, yielding him an active position and full equality. Another way to execute the knight manoeuvre Àf3-e5 was seen in the game E. Atalik-Lomineishvili, where instead of castling, White played 9.dc5 Ãc5 10.Àe5. Here the simplest way for Black to achieve equality is perhaps 10...0-0, but the game continuation 10...Ãc6 11.©d8 Õd8 12.Àc6 Àc6 brings Black very close to equality once again. After 9.0-0 Black has the choice between 9...Ãc6 or 9...Õc8.

Neutralizing the g2-Bishop

The move 9...Ãc6 was played at high level: by Anatoly Karpov himself in his match against the French grandmaster Joel Lautier in Ubeda, 1994. Black’s idea is clear: he would like to neutralize the g2-bishop. Here, in the 5th match game Lautier-Karpov, White played 10.Õd1, which is not the best because of 10...c4!. White’s main continuation is 10.Àc3, when Black has three main continuations. The (over-) ambitious move 10...c5?! reduces Black’s counterplay in the centre and after 11.©c2 Ãb4 12.Ãg5 0-0 13.Õad1 h6 14.d5! White had a decent position in the game P.H. Nielsen-Hjartarson. In the game Ribli-Pelletier, Black played 10...Ãe7 (10...cd4 is the third possibility for Black) and after 11.Õd1 0-0 (here once again Black can play 11...cd4) 12.e4 cd4 13.Àd4 ©b6 14.Ãe3 Àg4 the experienced Hungarian grandmaster (and former two-time World Champion candidate) played the clever knight jump 15.Àf5!, after which White had the initiative but Black’s defence was strong. The Main Line

The main line of this whole variation (4...dc4 5.Ãg2 Àc6 6.©a4 Ãd7 7.©c4 Àa5) is 8.©d3 c5 9.0-0 Õc8.

._TdMl.t jJ_L_JjJ ._._Js._ s.j._._. ._.i._._ _._Q_Ni. Ii._IiBi rNb._Rk. Here, after 10.Àc3, the main continuation for Black is 10...cd4 (10...Ãc6 is the alterna-

tive). After 11.Àd4 Ãc5 (11...©b6 is an alternative) in the game Raznikov-Shengelia, White played the strange rook move 12.Õb1. Black followed the best strategy of neutralizing the g2-bishop with 12...Ãc6!, and after 13.Õd1 Ãg2 14.©b5 (a fairly typical intermediate check in our variation) 14...Àd7 15.®g2 a6 Black was OK. In the game Ilincic-Antal, White played the more natural rook move 12.Õd1, and after 12...0-0 13.Ãg5 h6 14.Ãf6 ©f6 15.Àe4 ©d4 (15...©e7 is another option for Black) 16.©d4 Ãd4 17.Õd4 Ãc6 18.Àd6 we have reached a position that was first given in the book by Israeli grandmaster Boris Avrukh, Grandmaster Repertoire 1.d4 Volume 1. White has a microscopic advantage, but with the best moves Black can equalize, we think. The German grandmaster Buhmann probably shares this opinion, because he avoids the line with 12.Õd1 (in 2008 it was actually a novelty from the Avrukh book) and plays 12.Ãg5 instead. In two games by Buhmann in the Aschach Open in December 2012, this continuation was tried against two young Austrian players. So far, we have only these two games in our line. In the first round, in the game Buhmann-Kessler, Black played 12...h6 13.Ãf6 ©f6 14.Àb3 Àb3 15.Àe4 ©e7 16.ab3 0-0 17.Àc5 Õc5, and after 18.Õa7 White won a pawn. It seems that this is a critical position of the 12.Ãg5 line. Kessler played 18...Ãb5 19.©e3 Õc7 here, and now White got the better prospects with 20.Ãf3. Only four days later, in the game Buhmann-Fröwis in the same Austrian Open, the other young Austrian player improved on Black’s play with 19...Ãa6!, and after 20.Õc1 (20.Õa1) 20...Õc1 155

21.©c1 Õd8 Black had full compensation for the pawn. There are so many Austrian examples (tournaments, players) in close connection with our variation that we think we are justified in naming it ‘a new Austrian line’ (analogous to the line 1.e4 d6 2.d4 Àf6 3.Àc3 g6 4.f4 in the Pirc Defence). We should also mention that there are many good open tournaments in Aus-

tria, and Austrian chess life as a whole is very intensive these days. The ‘brothers-in-law’ (this is how Hungarians like to refer to Austrian people, their neighbours) are becoming stronger and stronger. They already have a very strong grandmaster, Markus Ragger, and some new talents are benefiting from trainings by the Hungarian grandmaster Zoltan Ribli.

There are not too many recent high-level games at the moment, but we can already discern some trends. In this line Black plays mainly for equality, for simplifications and for symmetrical positions. White certainly has some initiative, but with good and precise play Black can equalize. At the same time, he cannot hope for more.

Ts.d.tM_ jL_._JjJ .j._Js._ _._._.b. .lBi._._ _.n._N_. Ii._.iIi r._Q_Rk. This line, which in the Sokolov’s monograph The Strategic Nimzo-Indian (New In Chess 2012) is called the Karpov Variation, has a clear strategic basis. Black likes to play against the isolated pawn, even with a ‘wrongly-placed’ bishop on b4. However, in some positions Black can make use of this situation by exchanging on c3 and creating another basic motif: the hanging pawns. As we will see, this line is best suited to strategic players. In the diagram position White has several continuations: A) 11.Àe5, B) 11.©e2, and C) 11.Õc1.


11.Àe5 looks very straightforward.

Ts.d.tM_ jL_._JjJ .j._Js._ _._.n.b. .lBi._._ _.n._._. Ii._.iIi r._Q_Rk. White wants to prevent the development of the b8-knight by threatening to destroy the pawn structure in front of the black king after, for example, ...Àbd7 Àxd7 and Ãxf6. The easiest way to react for Black is to take on c3 immediately. After 11...Ãc3 12.bc3 Àbd7 13.©e2 Õc8 14.Õac1 Black can liberate himself from the pin with 13...Àe5 14.de5 ©c7. The doubling of pawns after 13.Àd7 ©d7 14.Ãf6 gf6 is not dangerous for Black. The slight weakening of his king’s position is compensated for by his strong bishop and the open g-file (ShirovNaiditsch). There are also no problems for Black if he wants to keep more tension on the board. In the game Onischuk-Hracek, for example, Black played 11...Àbd7 12.©e2 Õc8 13.Õac1 h6! (instead of taking on c3) – a typical and very important

manoeuvre: after 14.Ãh4 Àe5 15.de5 ©d4 the queen attacks two bishops. After the virtually forced 14.Àd7 ©d7 15.Ãf6 gf6, as we have seen before, there are no problems for Black. Even a move like 11...Àc6 may equalize after 12.Ãa6 Ãa6 13.Àc6 ©d6 (A. Mastrovasilis-Howell). Maybe the most principled reply to 11...Àc6 is 12.Ãf6 ©f6 13.Àd7 ©h4 14.Àf8 Õf8 – an exchange sacrifice. In the past few years there have been no new ideas here, which is why we have not included it in this Survey. Solid

11.©e2 is a more solid continuation. White wants to first prepare Àe5 with Õac1 and Õfd1. The main drawback, as with 11.Àe5, is that White does not prevent the 163

...Ãc3 exchange. As in the previous line, it is safe for Black to take on c3: 11...Ãc3 12.bc3 Àbd7 13.Õc1 ©c7 14.Ãd3 Àg4

T_._.tM_ jLdS_JjJ .j._J_._ _._._.b. ._.i._S_ _.iB_N_. I_._QiIi _.r._Rk. An important position for this line. With the threat ...Ãf3 and ...©h2 Black forces the exchange of one pair of bishops, which is in his favour in positions with hanging pawns (with fewer pieces on the board defending is easier). After 15.Ãe4 Ãe4 16.©e4 Àgf6 Black had good chances to keep an equal position in the games RadjabovKramnik and Nakamura-Giri. A quite interesting idea instead of 13.Õc1 is to play 13.Àe5 ©c7 14.Àd7. Black has tried to take on d7 with both pieces, knight and queen (see Navara-Svetushkin and Hracek-Rogozenco), but in both games White achieved a very slight advantage.

pawns, and after ...Ãc3 he will recapture with the rook. In the diagram position Black has two general plans: C1) 11...Àc6 C2) 11...Àbd7 Variation C1

The move 11...Àc6 avoids several lines like Àe5 or ©e2, but on the other hand, the knight is not as stable on c6 as on d7. Black’s plan may involve ...Ãe7 and ...Àb4-Àd5 (SokolovHarikrishna) or ...Ãe7, ...Õe8, ...g6 (Naiditsch-Leko). In both cases Black had a quite passive position. Probably more promising is to play a kind of ‘advanced ...Àc6 line’ by playing 11...h6 first, and only after 12.Ãh4 Àc6, with the idea to play ...Ãe7, followed by the exchange of dark-squared bishops with ...Àh5. This favours Black. In Sokolov-Leko and Khismatullin-Bocharov, Black was fine. Variation C2 11...Àbd7

A more solid move than ...Àc6. Black protects his knight on f6, also preparing to defend with ...Õe8 and ...Àf8 against White’s attack on his king. 12.Õe1

The Main Line 11.Õc1

Ts.d.tM_ jL_._JjJ .j._Js._ _._._.b. .lBi._._ _.n._N_. Ii._.iIi _.rQ_Rk. This is the main line. White wants to avoid the hanging 164

T_.d.tM_ jL_S_JjJ .j._Js._ _._._.b. .lBi._._ _.n._N_. Ii._.iIi _.rQr.k. Following the main line. Here White has also played 12.©e2, which is similar to the 11.©e2 line. If Black now plays 12...Õc8

12.Ãd3 Ãc3 13.bc3 ©c7, White can play 14.Ãh4! (to avoid having to exchange the bishops on e4 after ...Àg4), as in Mchedlishvili-Lalith. In the recent game GelfandKramnik, London Candidates’ 2013, Black tried the original 12...©b8, with the idea of keeping the rook on a8 in order to support the important push ...a7-a6, play ...Õc8 and ...Ãd6 to create some pressure on White’s king position and force him to exchange several pieces. This plan generally proved to be quite OK for equality. 12...Õc8

is a logical continuation to revive the idea of ...Ãc3. In the games of Viktor Bologan we can see the inclusion of the moves 12...h6 13.Ãh4, which is more in White’s favour. Similarly to Mchedlishvili’s game, Black could not neutralize the white bishop on h4 and the same happened in the game against Wang Hao. 13.Ãd3

is the strongest move here, with the idea of keeping control of the diagonal a6-f1 after his next move, ©e2. For this reason 13.Ãb3 looks a little dubious in view of 13...Ãc3 14.bc3 b5, fixing the hanging pawns. There is one other popular continuation: 13.©b3 Ãc3 14.Õc3. This does not yield White any dividends after 14...h6 15.Ãh4 ©e8 (Lauber-Ruck) or 15...Ãd5, as Macieja played against Salinas Herrera. His strong control of the d5-square gives Black at least equal chances. 13...Õe8 14.©e2

Following the strategic line. The straightforward attack 14.Ãb1 does not promise much for White, as the position of the black king is strong enough. After 14...Ãe7 15.h4 a6 and

20.Ãf2. Still, in the game Black had good chances to equalize. In the later game Potkin-Harikrishna, Black improved this line with 18...©d6 (with the idea of meeting 19...Õc3 and ...©d4 with 19.f3) 19.Ãg5 e5, with good counterchances. Conclusion

At the moment Black has good chances to equalize, especially with the recent plan with ...h7-h6 and ...Àc6 (Sokolov-Leko), and the main line is also quite safe (Potkin-Harikrishna). White’s chances will increase if he can avoid the neutralization of his g5-bishop (Ãg5-h4-g3).

winner annotated the game and gave my early ...h7-h6 a ?!. In his extensive notes he mentioned neither the real reason behind my draw offer on move 19, nor the critical continuation right after it. In the next few days, my friend IM Dimitar Marholev somehow accomplished the ‘mission impossible’ of bringing me back to the chessboard – in January we took part in three more events. I only gave up playing the Vienna Variation – well, not forever. How could anyone have predicted that one day the same line would enable me to score my final norm?

Mixed Feelings

Alexey Kuzmin recently presented us with a lovely description of Vienna. It reminded me of my own experience in the eponymous variation with joy and a touch of bitterness, too. 30th of December, 2006 – my first New Year’s Eve outside Bulgaria was about to become the happiest in my life. The Christmas Open in Bethune (France) was going very well for me; at some point I was even leading the field. A first grandmaster norm would have been a perfect way to end the year. Alas, an exciting last-round battle in a sideline of the Vienna ended tragically for me, although the desired draw was within reach till the final minutes... Later the

The New Trend in the Vienna

It looks like the first extensive coverage of the Vienna with the move order that I used in 2005-2006 (6...c5 7.Ãc4, and now 7...h6) was by Hungarian theoreticians Lukacs and Hazai in Yearbook 20 (1991). They were skeptical of it, too. As a rule, opening systems adopted by Kramnik open a new page in chess theory. Two extraordinary games between him and Ivanchuk changed people’s attitudes towards the immediate elimination of the bishop. Karolyi’s excellent work in Yearbook 94 inspired me to take up my old favourite again. Facing Serbian IM Goran Arsovic in 2009, I emerged victorious from

the complications and had little doubt about relying on the line in the future. It should be noted that Kramnik’s 6...h6 must be regarded as the most precise move order, since 6...c5 invites 7.e5. The new main line goes on with 7.Ãf6 ©f6 8.Ãc4 c5 9.0-0 0-0 10.e5 ©d8, which both Lukacs/ Hazai and Karolyi dealt with. Various transpositions are possible, depending mainly on the timing of the e4-e5 advance. Since 2009 many famous grandmasters have added the system into their repertoires and an update is necessary. Let me first examine the deviations. Ragozin Style

The queen check 8.©a4 is the only serious alternative to 8.Ãc4 and 8.e5. 171

TsL_M_.t jJj._Jj. ._._Jd.j _._._._. QlJiI_._ _.n._N_. Ii._.iIi r._.kB_R Black is forced to react vigorously to avoid finding himself struggling against the solid enemy centre. After the forced 8...Àc6, 9.e5 was parried with the clever 9...©g6! (DelchevZelcic, Zadar 2009). This additional resource is less effective in reply to the main move 9.Ãc4, as White can then castle, when the pawn on e4 is immune. Correct is 9...Ãd7.

It was quoted by Karolyi in his notes to Ftacnik-Mirzoev (YB/94-185), but was not included in the explanatory part of the Survey. White has two more ways to defend the attacked pawn. The other queen retreat 10.©d1 is rather passive (in the normal Ragozin the queen usually has the c2-square at its disposal), 11.d5 is not a threat and Black can exert more pressure by means of Stohl’s 10...g5!?. The ‘greedy’ 10...©g6 11.©e2?! 172

©g2! yielded him an advantage in P.Toth-G.Honfi, but 11.0-0! is the principled continuation; see the notes to the game BozicS.Vukovic, played in 1947! 10.Ãb5 deserves attention as an attempt to keep the proud central duo, but it has not been tried yet. For example 10...Ãc3 11.bc3 ©g6 12.0-0 ©e4 seems perfectly playable and safe here, although it needs practical testing too.

rience any difficulties either. Karolyi already explained in detail how Black should neutralize the straightforward 13.d5. Finally, if Black is not satisfied with the ensuing structure, he can withdraw the queen to e7, when 9.Ãc4 is the only sensible continuation. Now 9...c5 transposes directly to lines which will be discussed below under the move order 8.Ãc4 c5 9.e5 ©e7.

Early Advance

Extra Options

White can start with 8.e5, aiming for Ivanchuk’s imaginative idea of 8...©d8 9.©a4. After 9...Àc6 10.Ãc4 Ãd7 11.©c2

The main reply to 8.Ãc4 c5 9.e5, however, is 9...©d8 and here the paths diverge:

Many extensive analyses have failed to yield a direct refutation of his set-up. However, the new try 12.Ãe2! c5 13.dc5 seems to set Black serious problems – White is intending to make good use of the opened files with his advantage in development. His strong initiative resulted in a quick victory in Edouard-Magem Badals. Practice has confirmed that Black can obtain a solid position with 11...Àe7! 12.0-0 Ãc6. Thanks to his firm control of the centre, which allowed him to postpone castling, Grischuk went on to beat Alexeev. In the stem game for 11...Àe7! Ragger played 12...0-0 and did not expe-

After 12.bc3 0-0 13.0-0 we arrive at one of the key positions of the system, which is usually reached via the move order 9.0-0 0-0 10.e5 ©d8 11.d5 etc.

Survey NI 27.13

Now Black has to find a decent plan for mobilizing his forces. In the 25th world correspondence final I introduced the novelty 13...Àa6, which is directed against the dangerous bishop. My encounter with the strong German ICCF grandmaster Frank Schröder proved its reliability. Furthermore, from c7 the knight will stop the break e5-e6 for a long time. In essence, the ideas behind ...Àb8-a6 are not new, and this manoeuvre looks more logical to me than the set-ups with developing the knight to c6. These will be examined in Part II via the main move order 9.0-0 0-0 10.e5 ©d8 11.d5. B) 10.0-0 is a step towards the tabiya position discussed in Part II, but here 10...cd4 can make a difference.

In my game against Arsovic, 11.Àd4 was met by the optimistic 11...Ãc5?!, which brought me success, but later failed to pass the computer test. Instead, the simple 11...0-0 promises Black excellent prospects. Tregubov did not find anything better than 12.©g4 and had to prove compensation for the missing pawn after 12...©c7!. The same double attack was seen in Baikov-Grigoriants after 12.Àe4, and White went down

under an exciting tactical operation crowned by 20...©g4!. All in all, his choice on move 12 is limited to 12.Õc1 Ãc5, and without the queens Black should not be worse. White’s best chance lies in 11.Àe4, used by, for example, Mamedyarov in a victorious blitz game against Kramnik. This dangerous attacking mechanism with a knight transfer to g3 and preparing a ©e4/Ãd3 battery, will be the subject of Part II of this Survey. Here, in comparison with 9.0-0 0-0 10.e5 ©d8, White is deprived of the straightforward 11.©e2, bringing one of the rooks to d1 after 11...cd4, although it can finally result in a transposition. A Noteworthy Alternative

9...©e7 is a noteworthy alternative to 9...©d8. I used this against the future GM Feller. This game did not appear in Yearbook 94; possibly because it was drawn in just 18 moves. After 10.0-0 I chose 10...Ãc3 11.bc3 cd4 12.cd4 Àc6, trying to prevent the manoeuvre Àd2-e4-d6. In the game, 13.d5 led to simplifications, but 13.Àd2 was nevertheless possible – albeit at the expense of a pawn. The same goes for 11...0-0, when White’s best bet for an advantage is 12.Àd2, as pointed out by Karolyi. Instead, two great players did not get much out of the opening and lost their games – Alekhine with 12.©e2 in a simul and Gligoric to Kostic after 12.d5. The latter move was once given pole position in the theoretical article by Lukacs/Hazai in Yearbook 20. Anyone who has just delved into the ramifications of 10.d5 with a queen on d8 can hardly agree with them – the location of her majesty on e7 evidently favours Black.

In another game by Feller, Harkany 2009, in which he postponed the e4-e5 advance till move 13, he could not do without d4-d5 either. We will soon get back to Wirig’s reaction. Here is one other fresh idea that may inspire more confidence in 9...©e7, or in 8...©e7 in reply to 8.e5, respectively. During the 2011 European championship, Feller took the black side and played 10...cd4 in his game against Kozul.

After 11.Àe4 0-0 12.©d4 Õd8 13.©e3 the French grandmaster improved on those classic examples with 13...©c7 and calmly repelled the aggressive 16.g4 to grind down the former champion. A month later, Banusz gave the novelty a second try and Greenfeld’s spectacular 14.Àf6 gf6 15.ef6 proved enough for a draw only after the correct reply 15...Àc6!. New practical examples are definitely needed, and more refinements can be expected. To sum up, the move order with 8.Ãc4 c5 9.e5 offers Black more extra possibilities than the natural 9.0-0. Castling First

After 8.Ãc4 c5 9.0-0 it is time for Black to castle as well (this 173

will be examined in Part II), but he still has alternatives:

A) 9...cd4 is enjoying unexpected popularity, but 10.Àb5! has always been the critical reply to this, when 10...©e7 11.©d4 0-0 12.Àa7 wins a pawn. Many grandmasters seem satisfied with the sequence 12...Ãc5 13.Àc8 Õc8, and in most of the games the opposite-coloured bishops compensated for the small deficit. Such a course might not be to everyone’s taste and it will therefore not be discussed in this Survey.

B) 9...Ãc3 leads back to the beginning of this Survey and my 2006 story. The rest can be seen in the few remarks to l’AmiNinov next to the original annotations. In the above-mentioned game Feller-Wirig, Harkany 2009, Black did not hurry with the capture on d4 and castled first. After 11.©e2 he prevented the plan l’Ami had executed against me: Àe5, followed by a quick march of the f-pawn. The ensuing positions are in the spirit of the Semi-Tarrasch – Wirig’s subtle move order 11...Õd8 12.Õad1 Àd7 deserves serious attention! Conclusion

Queen checks are objectively not dangerous for Black. After 8.©a4 Àc6 9.Ãc4 he must reply 9...Ãd7! and continue with active play against the central pawns. Ivanchuk’s invention 8.e5 ©d8 9.©a4 Àc6 10.Ãc4 should be met analogously –

[10...g5! seems to be the most energetic reaction to the queen’s passive retreat –

10...Ãd7 11.©c2 and now 11...Àe7! looks rock-solid. The other early advance 8.Ãc4 c5 9.e5 offers extra possibilities only to Black. The retreat to e7 is now being reassessed due to the games of the young French grandmasters Wirig and Feller. The same applies to the voluntary exchange on c3, which is playable and equally unexplored. Kramnik’s 9...©d8 remains the top answer, and in reply to 10.0-0 Black can insert 10...cd4!?. Aronian and Radjabov are the promoters of 10.d5, which usually transposes to the variation tabiya 9.0-0 0-0 10.e5 ©d8 with 11.d5. I am expecting a growing popularity of the novelty 13...Àa6!?. The subject of Part 2 in Yearbook 108 will be the main tabiya and White’s most dangerous plan with 11.Àe4, as well as the possible deviations.

T_L_.tM_ jJj.jJlJ .sSd._J_ _._._._. ._.iI_._ _.n.bI_. Ii.q._Ii _.kR_BnR In the set-up with 3.f3, Grünfeld players face a rather unpleasant choice. Black has to follow a relatively narrow path. White builds up a massive centre, and it is not easy for Black to find an active plan. Anand successfully tried 3.f3 in the World Championship match against Gelfand. His victory in Game 8 was examined by Kapengut in Yearbook 106. 3...d5 naturally leads to ‘Grünfeld-like’ structures. There is a great number of new games in this line, and it is very difficult to follow the new developments. Black can choose from three plans on move 9: 9...e5 is the older main line, but it does not look like a very practical solu182

tion, as the most Black can hope for is a draw with precise play. The second possibility is 9...f5, which leads to a very sharp hand-to-hand fight. One weak move, and Black finds himself in a lost position. (This is the biggest problem in the Grünfeld in general.) The third possible move is 9...©d6!?, which is the subject of the present Survey. The queen move prepares ...Õd8, and keeps an eye on White’s queenside (b4). It is a versatile and novel move with not too much theory. As it keeps the position flexible, Black can carry out several different plans. Numerous strong grandmasters play 9...©d6!?, e.g. Aronian, Caruana and Areschenko, to name just a few.

I prefer 16.Àb5 ab5 17.h5 Àc4 18.Ãc1 f5!? 19.Ãd3, when Black’s initiative seems to peter out. In the Grünfeld, this is usually bad news, signifying that he is worse. See the game Thorfinnsson-Gordon, England tt 2012/13. B) Black’s other option is 13...Àe5 14.Ãd4 c5!?. A rather typical Grünfeld pawn sac aimed at opening the position and speeding up Black’s development. After 15.Ãc5 Àec4 16.Ãc4 Àc4 17.©c1 ©c7 18.Ãd4 e5 19.Ãf2 b5!

If White plays 15.h4 instead of 15.Àf3, Black can spare the move ...f7-f6:

Conclusion

9...©d6!? – the third way – is naturally not a ‘cure-all’, but it leads to an interesting and complicated struggle, with playable positions for both sides. No wonder that it occurs in tournament practice week by week. The move 9...e5 seems to be gradually losing ground. 183

The Beginning or the End of a Line? by Tibor Karolyi (special contribution by Anish Giri)

TsLdM_.t jJ_.jJ_J ._._.lJ_ _.jI_._. ._.i._._ _.n._._. Ii._IiIi r._QkBnR In the 2012 game Akobian-Giri the Dutch number one player, as Black, came out of the opening with a winning position. His opponent played his usual 4.Ãg5 line against the Grünfeld. Anish chose the move 4...Ãg7!?, and after 5.Ãf6 Ãf6 6.cd5 came up with the relatively new 6...c5!?. In his analysis in New In Chess he calls this the right way to exploit the absence of the darksquared bishop. The move was first played by Fernandez Quintero in 1997. In that game White answered 7.dc6, which transposes to the 6...c6 line. That variation is not covered in this Survey. It was in 1999 that White first tried 7.dc5. In the past two years the move 6...c5 was tried by super-players like former World Champion Topalov.

A Rare Line

White rarely plays 7.Àf3. In 2012 there were two games with 7...cd4 8.Àd4 ©b6. In the game Demuth-Admiraal, Wijk aan Zee 2012, White got no advantage after 9.e3 ©b2, but Dreev beat Melkumyan, and he was winning after the opening. However, objectively Black shouldn’t be worse. In 2013 Laylo did not take on d4, but played 7...©b6. After equalizing once he could have been in trouble, but his idea looks like an even simpler way to equalize. The Main Line

After White’s 7.dc5, Black may play 7...0-0, as happened in one game. I analysed it. White can keep the extra pawn, but as usually in this line he has problems what to do with it against the two bishops. In the game Al SayedMelkumyan, Sarajevo 2011, the Armenian grandmaster played the older option 7...©a5.

Geetha Narayanan Gopal

This had been tried a few times in lower-rated players’ games. White swapped queens with 8.©a4, but Black did fine in the ensuing queenless middlegames, the black bishop compensating for the pawn deficit. Black did all right in the game Al SayedMelkumyan as well; White’s idea of 8.©d2 Àd7 9.Àe4 caused no problems for the young Armenian player. However, I do not see how Black can equalize against 8.Õc1, after which White may close in Black’s dark-squared bishop with f2-f4 and e4-e5. Gopal’s Novelty

In 2011, Indian grandmaster Geetha Narayanan Gopal introduced 7...Àd7. His opponent Moiseenko answered 8.©a4, but after 8...0-0 was unable to equalize and lost. At one point I sug189

gest an improvement for him. Topalov deviated from that game on move 8 by playing 8...©c7.

endgame with the 7-piece tablebase. Remarkable only moves!

He claims that his opponent’s play suggested to him that Akobian did not really know the line. In Balog-Erdös (2013) Giri’s suggestion 9.Ãc4 was tested. Black doesn’t need to simplify into a lost position. White can try other ideas as well.

A Decent Move

The move 8.e3 was tried by decent grandmasters in several recent games. Suat Atalik tried 8...©a5 against the experienced Dusan Rajkovic. The position got stirred up, favouring Black, who won the game. If things had remained calm, Black would have had no problems.

T_LdM_.t jJ_SjJ_J ._._.lJ_ _.iI_._. ._._I_._ _.n._._. Ii._.iIi r._QkBnR This move defends the d5-pawn, but gives up the d4-square on the diagonal, making the darksquared bishop more powerful. Negi created an isolated d-pawn in White’s camp and obtained a position with two bishops versus two knights. White did not get a chance to hurt Black and actually had to suffer for over 100 moves to draw in the end. Agdestein-Hammer is promising for White, but it is too early to draw conclusions. I checked the 190


Wang Hao went for a complex position. The former World Champion took over and got close to winning, but the Chinese player managed to hold. I checked a few deviations from Wang Hao, but Black seems to have an easy game against White’s other plans as well. In the game of two young Indian grandmasters, Gupta and Negi, Gupta tried 8.e4.


Robin van Kampen

Two young Dutch stars played differently and chose 8...0-0.

T_Ld.tM_ jJ_SjJ_J ._._.lJ_ _.iI_._. ._._._._ _.n.i._. Ii._.iIi r._QkBnR In the game Michalik-Van Kampen (2012) Black developed the queen to b6, while Giri, against Akobian, moved it to a5. Van Kampen first equalized and then managed to take over and win, Giri emerged from the opening with a winning position.

In general the idea of 4...Ãg7 with 6...c5 looks nice for Black. Black often has to play with material down, at least temporarily, but this is nothing new to Grünfeld players. I was told that Gata Kamsky said in an interview that top players had shifted to 1.d4 because of the Petroff Defence. I remember Van der Wiel once wittily asking the question: who will win the Nobel Prize for chess openings? What he meant was: who can obtain something for White in the 3.d4 Petroff? I recently looked into a few Grünfeld lines and noticed that several new ideas are emerging for Black. If in the other Grünfeld lines White finds as little as he does in the one discussed in this article, top players may have to go back to the Petroff, trying to find something. It is hard to tell whether we are witnessing the beginning of a popular line for Black or the end for White. At the moment it looks like white players should look for other weapons. But in the opening one never knows. Let me just cite an example. I guessed that Peter Dely, who sadly passed away in early 2013 (see the FORUM section of Yearbook 106, pp. 29-31 – Editors), probably would have never imagined that his gambit would be asleep for decades and then it would be played at the World Championship final, and that Kasparov’s win would be voted the best game ever in Sahovski Informator.

TsLdT_M_ jJ_._JlJ ._Jj.sJ_ _._._._. ._InI_I_ _.n._I_. Ii._B_.i r.bQ_R_K It was the 21st of February 2013, and I was participating in the Open Championship of Central Serbia, which constitutes a qualification tournament for the National Championship. I was going to face grandmaster Markovic with white. Since it was a morning game, I did not have enough time to prepare. One of the lines I was expecting, however, was the Classical Variation of the King’s Indian Defence with 7...ed4, followed by …Õe8, …c7-c6 and …Àh5. This opening has recently become popular even at top level. Somehow, I was always a little

suspicious about this line and a new idea from the stem game Tosic-Markovic came to my mind: the smashing 14.Àf5!. Of course, in this move order, I discovered that Black can play better, so I devoted my attention to the concrete 12.Ãf4, which almost forces Black to play 12...h5, creating weaknesses on the kingside. I decided to just play 13.Àf5!, and even though I didn’t have enough time to check all the lines, I felt that there should be more than adequate compensation due to White’s spatial and development advantages, as well as his positional pressure. All these factors give White a strong initiative and therefore should provide great positional compensation for the sacrificed material. After the game I analysed all the possibilities more deeply, and I think that now is the right time to share my findings with the Yearbook readers. Preparing the Sacrifice

After 12.Õg1, everything is ready for the Àf5 sacrifice if Black plays …h7-h5. I think Black should try a different strategy: playing on the queenside, without inserting …h7-h5, as this leads to a white initiative by force. The best plan, in my opinion, as already mentioned with reference to the game TosicMarkovic, might be 12...Àa6,


by Dejan Antic

Rustam Kasimdzhanov

keeping the option of …Àd7 followed by …Àb6, or …Àe5 if White doesn’t play 13.Ãf4. Otherwise, Black can use a plan involving the …g5-g4 sacrifice as in the above-mentioned game. Another interesting possibility is the flexible 12...a6, as seen in Shimanov-Ding Liren. In general, White can claim some advantage thanks to his space advantage, but it is not, I think, the maximum White can reach for. Keeping the Option of f2-f4

After 12.Ãe3 h5 13.g5 Black has two possibilities: either 13...Àh7 or the new approach 13...Àfd7. I prefer the latter, as it gives more flexibility, and in both GelfandRadjabov and Beliavsky-Bruzon Batista Black achieved strong counterplay. The older approach 195

13...Àh7 seems to be too slow, as the knight stays out of play. A very instructive and impressive game worth studying is FierFlores. One of the questions might be: after 12...h5, why not play 13.Àf5 at once? Of course here we can see a big difference. The answer is simple: after 13...gf5 14.gf5 Ãf5! the bishop on e3 is hanging! Immediate Pressure on d6

12.Ãf4, followed by ©d2 and Õd1, is the most concrete white plan. Black has to react with 12...h5.

Radjabov, Gelfand-Grischuk and Fressinet-Delchev provide us with instructive examples as to how Black can equalize. This is why I thought that this was the right moment to try 13.Àf5!, which I played.

If 13.g5 Àh7 Black has good counterplay, thanks to the manoeuvre …Àd7-Àe5, followed by …Ãc8-Ãe6, …a7-a6. Preparing the advance f2-f4 seems too slow. The games Topalov-

I am still not sure how Black should react. During my preparation for the game, I was mostly concerned with Black’s possibility to opt for immediate counterplay with 14…d5, but then I discovered that White has more than enough compensation. Other passive lines, such as …Àbd7, …Àh7 or …®h8, give White enough time to create strong positional pressure all over the board, combined with an attack along the open g-file. I was very happy and proud that I played this novelty… only to

find out later that Anton Shomoev had already played it only a week before, in a rapid game against Surya Shekhar Ganguly! Just Played!

Shortly before going to print, two months after its inception in February, the very position after 13.Àf5 appeared on the board again – at top level! In Kasimdzhanov-Topalov, Zug 2013, Topalov opted for 14...d5, a line of defence I had originally been concerned about. However, on move 20 he didn’t continue in the best possible way – see my notes. One wonders: did Topalov know of this idea before the game? Conclusion

The main question remains: is it game over or not after 13.Àf5! ? As for me, I am ready to play this move again. But let us wait for some more games in order to find out Black’s answer and see if it is going to be tested again. If not, this means that the plan beginning with 10...Àh5 is dubious. Meanwhile, I hope all Yearbook readers will enjoy this article and the games and exercises presented on these pages.

King’s Indian Defence

Averbakh Variation KI 24.4-6 (E75)

The Quick …c7-c5 vs the Averbakh by Damian Lemos Sarro

d4 c4 Àc3 e4 Ãe2 Ãg5

Àf6 g6 Ãg7 d6 0-0

TsLd.tM_ jJj.jJlJ ._.j.sJ_ _._._.b. ._IiI_._ _.n._._. Ii._BiIi r._Qk.nR Nowadays (as always!) the King’s Indian is a sharp and powerful way of facing the 1.d4 player as Black. We see this defence at top level as well as at lower levels. There are lots of ways to face the King’s Indian, but it’s really hard to tell which one is best. The classical main line, in which White plays Ãe2, Àf3 and 0–0, usually offers White very nice chances on the queenside, but he has to face a strong attack on the kingside. If you are looking for a positional game, for instance, you can choose the Fianchetto Variation, where White plays g2-g3, Ãg2 etcetera. Space Advantage

However, we can also opt for the Averbakh Variation, where 202

White plays Ãe2 and Ãg5, delaying the Àg1’s development. After 1.d4 Àf6 2.c4 g6 3.Àc3 Ãg7 4.e4 d6 5.Ãe2 0-0 6.Ãg5, one of White’s ideas is to prevent Black from playing his most natural move in the King’s Indian: …e7-e5. If Black plays 6...e5? here, White wins material after 7.de5 de5 8.©d8 Õd8 9.Àd5!, a useful trick to remember. NEW IN CHESS

Not Allowing Any Counterplay

In this Survey we are going to analyse one of the most popular reactions by Black involving a quick …c7-c5, focusing on the newest game in this line between grandmasters Magnus Carlsen and Loek van Wely, played in the Tata Steel Chess Tournament of this year: 6...c5 7.d5 e6 8.©d2 ed5 9.ed5.

TsLd.tM_ jJ_._JlJ ._.j.sJ_ _.jI_.b. ._I_._._ _.n._._. Ii.qBiIi r._.k.nR As you will see in the games analysed in the Game Section below, our idea as White is to play with a space advantage (pawns on c4-d5 against pawns on c5-d6). We will also see manoeuvres

Magnus Carlsen

such as Ãe2-d1-c2, or the key pawn advance a4-a5 to win space on the queenside. In my opinion, the common factor in these games is that White plays for a win in a solid way, not allowing any counterplay to his opponent. Conclusion

As you will notice in the Game Section, White often gets a riskfree position with lots of extra space. Our goal as White is to play a favourable endgame thanks to this space advantage. In the game Carlsen-Van Wely we will see some tactical skirmishes in the opening, but after the manoeuvre involving Àh4! and f2-f3 it looks like we can avoid complications and still get a much better endgame as White. No fun for Black!

We want to enjoy our space, and see how the pawn on d6 is going to be quite weak for the rest of the game. We’ll have to be careful with the open h8-a1 diagonal and the e-file as well, but once we finish our development, I think White can claim an advantage] 9...©b6 10.Àf3 Ãf5 [Black is lacking space so it makes sense to trade a couple of pieces.

RnBkQbNr iI_I_.iI ._I_._._ _._._I_. S_.i._._ _J_._._. J_J_JjJj t.lMdLsT It was the 6th round of the 1992 Hungarian Championship. My opponent, Gabor Kallai, came up with the surprising 3.f3 after 1.d4 Àf6 2.c4 g6. He made it clear that he would be happy with a draw and needed no Grünfeld. I was tempted. After all I was leading by a clear point, ahead of Chernin, and there did not seem to be any reason to take chances. But then all of a sudden I discovered my Gambit – 3...e5!? 4.de5 Àh5. In a different tournament situation I would surely have thrown it in. But then I thought, I would analyse this carefully and keep it secret. I played 3...d5 and the draw was soon agreed upon. I have analysed the AA variation, and made a longish file. My witness is God Himself, but since He is too busy sometimes, Peter Leko and IM Adam 206

Time flew, and all of a sudden the world premiere of the Gambit took place between Kramnik and Leko (Tilburg, 1998). The fact that Peter won this game made the sensation even greater. Objectively speaking, Kramnik was better most of the time. Then he blew it. Following that game, a number of strange things came to light. First of all, Kramnik was not surprised by 3...e5, as he had worked out an antidote when preparing against Shirov, viz. 5.Àh3!.

This way of handling the position again confirms the late Geza Maroczy’s wise advice: ‘If you have a material advantage, always be ready to give it back for some other advantage’.


The World Premiere

Peter Leko

Then an almost unbelievable discovery was made. That is, two lesser-known Australian players had tested the gambit in real tournament play as early as 1993. Strangely enough, no one in this era of Mega-databases paid attention to their ‘test drive’. Let’s face it: who’s interested in anything played by ‘patzers’? In addition, the pioneer, called Mark Chapman, lost his game. If you go through this game you will see that at some point he was better, and later even winning. Still later a postal game from the 1980’s was published as an addendum to a Survey in Yearbook 48... Conclusion

Many fine players, including (the very young) Carlsen, played 3...e5, and with a total of 60

games was not manipulated. They represent quality. Such a balance is a trap for many because they go by statistics. We’re all feeble people. I remember we looked at the heading of a bulletin and not at the events of the game (there was no ChessBase at that time), not bothering to go

down to move 81, especially if the game was drawn. Naturally we were manipulated by the result. Chess is a very concrete game. No book, article, analysis etc. should be believed blindly. This also goes for our work given below!

In the previous Survey, in Yearbook 106, we examined the line where White takes the pawn on e6, which in the NIC Code System is classified under the King’s Indian. If White castles and lets Black take on d5, we have a ‘proper’ Benoni again. Please note that in this article we do not cover early Ãf4 lines by White, early h2-h3 lines by White, and …Àa6, ...e7-e5 lines by Black as in the Czech Benoni. It would be nice to include these, but space does not allow it. Concentrating on the Kingside

The study of this opening is com216

plicated by the fact that we can reach the position after 11...Õe8 via two move orders, 9...Õe8 and 9...a6 10.a4 Àbd7 11.Àd2 Õe8. The key move 11...Õe8 signals Black’s intent to concentrate only on White’s kingside. The main line goes 12.h3 Õb8 13.Àc4 Àe5 14.Àa3 and now 14...Àh5.

GM Boris Avrukh has strengthened White’s play considerably in his ‘Grandmaster Repertoire’ series. The Positional Defence

We call Black’s defence 9...a6 10.a4 Àbd7 the ‘positional defence’ to the Modern Benoni with g2-g3. 9...Àbd7 without …a7-a6 is a good line for Black too, but he will soon have to play ...a7-a6 anyway, so it’s a very ‘transpositional affair’. This is reflected in practice.

John Nunn

The principled way for Black to achieve active counterplay is by ...b7-b5 or ...b7-b6, opening the b-file. However, in this case Black must consider whether his a6-pawn will be weak. About the move ...f7-f5 we can say that it works only rarely for Black. Extreme caution must be exercised in playing ...f7-f5, because it invites White to open the centre and the kingside before Black has coordinated his forces. The e5-square is an important blocking square, and a pivot square for Black’s pieces in this opening. Black suffers from a lack of space, so he must exchange some pieces, especially White’s knights. However, simplification sometimes helps White as well, since his plan is then more obvious. Black will be able to gradually equalize, be-

cause his pawn structure is sound enough and he will be able to hold his own tactically. But he must be aware of White’s lineopening thrust b2-b4 on every move. Black must exchange White’s knight when it appears on b6. If, despite Black’s efforts, White achieves the move b2-b4, then Black can sometimes consider ...c5-c4. Of course, this won’t work every time. The threat of b2-b4 is real and Black often has to rely on tactics to counter it.

The strength of the Fianchetto System is clear. Black must play to equalize. He can win only after a big mistake by White. Black is very close to being squeezed in a positional vise-grips in this line. The white knight on e4 in the main line is very dangerous. All the same, we believe that it’s equal if Black plays precisely. However, in a more subtle sense, White has a positional edge. His position has no weaknesses and he has more space. The equality

Instead of the retreat 21...Àf6, what do you think of the tactical strike 21...Àb2 ? (solution on page 254)

In this position we recommend 23.Ãg5!. Why not 23.Ãf4, attacking the pawn on d6? (solution on page 254)

The most frequent deployment for the white bishop is f4. I give a summary of the most relevant games under this sub-heading. The straightforward manoeuvre to exchange the dark-squared bishops, Ãf4+ ©e3+Ãh6, is featured in five games. In Fressinet-Parligras White plays this at the expense of the pawn on b2, and even sacrifices a

second pawn after that, getting compensation but perhaps no more. White eventually erred and ended up losing to Black’s passed a-pawn. Bu XiangzhiIdani features a similar idea, but here White gives the a2-pawn; White did not play energetically enough and Black got an advantage and made his opponent suffer defending an endgame a piece down, which finally resulted in a draw. In Izoria-Du Shan, Black rejects the exchange with ...Ãh8 and fares reasonably well until White penetrates with his rook along the b-file. In Cvitan-Edouard, Black allows the exchange and White gets better chances in the ensuing middlegame, while StrikovicTatai also shows an early exchange of the bishops, with Strikovic playing a strategic advance of his h- and g-pawns in front of the king for the sake of weakening e5 for his knight. In the end this strategy paid off, but not without the aid of some tactics to justify it. Tal-Dzindzhichashvili shows an endgame 2Õ+À vs. 2Õ+Ã (light squares), which Black draws. A second game by Dzindzhichashvili (vs. Nunn) is also drawn with the help of accurate defensive tactics. KarpovGranero Roca is a patient positional battle in which the stronger player outmanoeuvres his opponent (with a previous ex-

change of the dark-squared bishops). Beim-Dür transposes to a position with Black’s bishop on the f8-a3 diagonal; it is mainly interesting because it shows the possibility, under certain circumstances, of White sacrificing an exchange on c5. RamirezWang Puchen shows a clever way by White to exploit the inaccuracy of Black’s early play – Black is swept off the board. Giddins-Emms deserves close attention, as it can be considered a model game from Black’s point of view, in the sense that he reaches a nice endgame with the bishop pair against bishop and knight. Emms impeccably converts the advantage. Charbonneau-Jakupovic is a heavy positional battle showing a nice 223

pawn sacrifice by Black in the endgame to activate his bishop pair. Bishop Not to f4

In some games White answers the development of Black’s bishop to g7 by trying to control the a3-f8 diagonal with his darksquared bishop. In Filip-Bilek, White did this in an original way, playing ©a3, followed by Ãd2-b4. Black established a barrier with ...f7-f6 and eventually exchanged his dark-squared bishop for the knight, after which White did not find a way to make progress in the ensuing middlegame. In Stahlberg-Szabo, to all appearances the stem game of this system, White played b2-b3 to

take the bishop to a3, allowing Black to play ...c6-c5 and win the pawn on d4 in exchange for keeping Black’s king in the centre. The middlegame was very sharp and complex, with Black defending well, resulting in a draw. Ovseevich-Varadi saw a similar idea, but in an even better version for White. Black castled queenside and his king was eventually massacred. IvkovVan den Berg (Ad, not Jeroen) also featured b3+Ãa3, but without queens on the board; soon an endgame with opposite-coloured bishops and a rook pair on both sides arose, in which the foothold d6 for White’s bishop gave him some advantage. When Black sacrificed the exchange to get rid of the annoying bishop,

White converted his material advantage. In Khasidovsky-Dvoretsky, White played Ãg5, later bringing the bishop to e3. Black played in the spirit of the Barrier scheme (see Part I of this Survey in Yearbook 105), but the surprising pseudo-sacrifice 16.Àe5! gave White an edge, which was quickly increased to winning proportions. Later on, weak play gradually let Black off the hook. In the first two parts of this series, lines where Black plays an early ...©d5 were presented. In Part III we will take a look at the games without that early queen centralization.

Winning with the Najdorf Sicilian Zaven Andriasyan



Zaven Andriasyan (1989) is one of the strongest grandmasters in chess country Armenia. In 2006 he was both European under-18 and World under-20 Champion. Andriasyan has been a regular Yearbook contributor for several years and now makes his debut with a highly personal monograph on his beloved opening, The Najdorf Sicilian. On the following pages we present an excerpt from one of the chapters on Bobby Fischer’s favourite move 6.Ãc4.

The book is written as a repertoire for Black, and covers all variations for White. The main idea of the book is that in all variations, Black tries to use a novelty first, to deviate from the main lines and surprise the opponent right from the beginning of the game, so as to make him feel uncomfortable. The book consists of 13 chapters, grouped into 4 parts, and I have tried to analyse all possible main moves which are played by White, and all possible strong answers to these moves for Black. Even the moves which are played rarely by White and are not considered to be good ones, are covered here. This has been done for two main reasons: first to show the contrast with the good move which is shown in the book, and secondly, because the so-called ‘secondary moves’ are the ones preferred by some players, who like the positions which are created after these lines. However, the secondary lines are not given as much space as main lines such as 6.Ãg5, 6.Ãc4 and 6.Ãe3, which are played most often and preferred by the elite players, and where there are a lot of interesting games. In this book, another interesting move is covered in detail, namely 6.h3, which is becoming more and more popular nowadays. The advantages of this rather strange move are explained in the book. My approach in this book is that Black’s main idea is to play ...e7e5. The reason why Black plays 5...a6 in the first place is that the im-

mediate 5...e5 runs into the annoying 6.Ãb5+. But after 6.Ãg5 and 6.Ãc4, Black has to change his plans, as we will see in Part I and II. Part I 1 – The Poisoned Pawn with 8.©d2 2 – The Poisoned Pawn with 8.©d3 3 – The Poisoned Pawn with 8.Àb3 Part II 4 – White Retreats the Bishop to b3 5 – 6.Ãc4 e6 7.0-0 – White Castles Kingside 6 – 6.Ãc4 e6 – White Alternatives on Move 7 Part III 7 – 6.Ãe3 e5: Knight goes to f3 8 – 6.Ãe3 e5: Knight goes to b3 Part IV 9 – The Positional 6.Ãe2 10 – The Aggressive 6.f4 11 – Occupying the Flank: 6.a4 12 – The Fianchetto 6.g3 13 – The Poisonous 6.h3 14 – Exercises

TsLdMl.t _J_._JjJ J_.jJs._ _._._._. ._.nI_._ _Bn._._. IiI_.iIi r.bQk._R In this chapter, we will examine the variation involving the transfer of the bishop to b3, which is the way Fischer preferred to play this line from 1959 onwards. White moves the bishop away from the twin threats of ...d6-d5 and ...Àxe4. At the same time, he prepares the march of the f-pawn and for the moment, does not spend a tempo on kingside castling and retains the possibility of castling queenside. But Black understands the dangers he faces, and decides immediately to neutralise the bishop by bringing his knight to d7 and c5; after the exchange of the bishop, Black will have no problem with the defence of e6, or along the a2-g8 diagonal. 1.e4 c5 2.Àf3 d6 3.d4 cxd4 4.Àxd4 Àf6 5.Àc3 a6 6.Ãc4 e6 7.Ãb3 Àbd7 8.Ãg5 A) This move is one of the most principled and dangerous for Black, who in several lines obtains a position similar to those arising after 6.Ãg5. The danger of the line consists in the fact that White places his pieces aggressively, whilst retaining the option of castling on either side, which retains a degree of flexibility and danger for Black. 8.0-0 Àc5 and now:

In the old days, opening monographs essentially told the story of ‘what had happened’ up to then. They were focused on the past. Researching skills were paramount, as the writer would often have to scrape around for any material of interest. The main sources would be earlier tomes, so classical references and comments would be repeated through the ages. The author’s own touch would often consist of finding a new idea in an obscure East European magazine or his local league. Back then, original analyses were few are far between. How could a minor master, who had taken to writing, go beyond or even contradict a great champion? In the 21st century, everyone has access to literally millions of games on their databases, plus the latest analysis engines. It’s all a click or two away. So in order to present the most relevant and instructive, an author worth his salt now has to skillfully limit the number of game segments. Interpreting the stream of variations produced by his electronic device is another requisite, explaining the ideas in human terms, relying on experience of analogous variations. In short: it’s out with the dusty and old, in with the fashionable, critical, and innovative. Influential authors such as Avrukh, Sakaev, Bologan and Marin have set trends with their analyses, novelties and foresight. Time will tell if any of the books below will turn out to be a spring-board for future developments.

Victor Mikhalevski Grandmaster Repertoire: The Open Spanish Quality Chess 2013 There were times when the Open was regularly seen at the highest level, Karpov-Kortchnoi (1978) and Kasparov-Anand (1995) especially coming to mind. But in the last few years it has been virtually ignored by the elite. The Open Variation could be placed in the same category as the Marshall Attack or the Modern Arkhangelsk, i.e. active, forcing and highly theoretical. However, whereas the other pair seem to be ever-popular, the Open has declined in popularity. Is it simply the vagaries of fashion, or is it deemed to have something wrong with it? Furthermore, there haven’t been any new books on the subject for more than a decade, which perhaps explains the absence of specialized works in the bibliography. Fortunately, Victor Mikhalevski has the pedigree to make up for this absence. He has extensively played the line himself, and has in addition written about 1.e4 e5 openings for the opening website Even so, I was taken aback when I starting turning the pages. The content really surprised me. I was expecting lots of archaic lines which had been analysed out to the end. But no! Far from it! In fact, so much is utterly new. Here’s a remarkable example: 1.e4 e5 2.Àf3 Àc6 3.Ãb5 a6 4.Ãa4 Àf6 5.0-0 Àe4 6.d4 b5

Mikhalevski also examines the main line with 13...Õb8 14.ab5 ab5 15.Àg5 Àe5 16.©g3 ©d6 17.Ãc2 and then both of 17...Ãb6 and 17...Ãd7. 14.Àd4

Mind-boggling! I don’t want to give the whole plot away, but you’ll find further details on pages 203-208! In the meantime, have fun analysing this variation. This is clearly no boring old line where Black is playing for a draw. This is bold, ambitious, dynamic, and exciting, isn’t it? Here is another example that is almost as original. 1.e4 e5 2.Àf3 Àc6 3.Ãb5 a6 4.Ãa4 Àf6 5.0-0 Àe4 6.d4 b5 7.Ãb3 d5 8.de5 Ãe6 9.c3 Ãc5 10.©d3 0-0 11.Àbd2 f5 12.ef6 Àf6 13.a4

ence, when I regularly played the Open, that many of my opponents would avoid it on move five. I was interested to compare his ideas with those of Marin in his 2007 Quality Chess publication A Spanish Repertoire for Black. 1.e4 e5 2.Àf3 Àc6 3.Ãb5 a6 4.Ãa4 Àf6 5.d3 b5

Marin opts for a restrained approach, always placing the bishop on e7, for example 5...d6 6.c3 Ãe7 7.0-0 0-0 8.Àbd2 b5 9.Ãc2 d5 and so on. 6.Ãb3 Ãc5 7.0-0

After 7.c3 d6 8.Àbd2 0-0 9.Àf1 d5! 10.ed5 Àd5 11.Àg3 (Degraeve-Mounier, Bastia 1999), Mikhalevski suggests 11...a5!, an advance that he seems to like in several analogous positions. 7...d6 8.c3 h6 9.h3 0-0 10.Àbd2

There are similarities with 5.©e2, but the curious point about the Worrall is that one of the editorial staff (Andrew Greet) had already written a repertoire book for White (Play the Ruy Lopez, Everyman 2006) on the subject. 239

As you will soon see, Mikhalevski again seeks ‘active piece deployment’, placing his king’s bishop on the most ambitious square c5, rather than settling for the more modest e7. 1.e4 e5 2.Àf3 Àc6 3.Ãb5 a6 4.Ãa4 Àf6 5.©e2 b5 6.Ãb3 Ãc5

As is evident from the sample lines above, even in the sidelines, the author has put in plenty of effort to find new and effective ways to combat White’s ‘Anti-Open’ systems. It’s noticeable how some lines almost cross into the realm of the Marshall or Modern Arkhangelsk. 240

He hasn’t always gone for the obvious choices in his repertoire, one example being the absence of the notorious Dilworth.

Here Mikhalevski opts for 11...Ãf5, which he considers the most reliable option, despite the fact that he has played both of the aggressive alternatives 11...f5 and 11...Àf2, the latter being the Dilworth Attack. I also get the impression that VM has taken pleasure in choosing those options for Black where he can offer the maximum of personal input. So much the better for us. There are so many wonderful new ideas, surely busloads of tournament goers will just have to try them in practice. However, before I get carried away with enthusiasm, the opening still has to pass the most important test of all. Any opening system will only become generally acceptable if it holds up in the current main lines.

...which he analyzes to a probable draw in the endgame. Well, I am personally convinced that this whole book is something


special. However, before I recommend it to all and sundry, I just have to mention one thing that bugs me about recent Quality Chess publications such as this one. It’s their approach to brackets. That’s right: brackets. In 2009 they obeyed normal grammatical rules (no full stops in brackets, unless the sentence is particularly long etc), but in the last four years they have moved to a situation where full stops are almost the general rule. So on page 169 of their 2009 publication The English opening, Volume One, mid-sentence one can find (13.Ãf4 allows 13...h5!? with some counterplay). Fair enough. This obeys the ‘standard rule’. In comparison, on page 151 of the Open Spanish, there is (13.Àe4 transposes to the main line below.). Can you see the difference? There is an added full stop. Quality Chess is doing this more and more, especially when a bracket begins with ‘a chess move’. Chess Evolution and Chess Stars also (frequently) do this. At times this addition comes across as ugly, and is often unnecessary, for example (Black can also ignore White’s last move with 9...0-0!?.), see page 108. This shift in approach started around 2010, and now there seems to be a genuine attempt to convert most brackets into complete sentences. Curious. Another typical 2009 example would be (Black has to lose a tempo in order to defend his central pawn), from The English Vol. 1, page 49. On the other hand, in 2012, they opt for (After 18.Õxf2 ©xd4 Black is a pawn up.), see page 36 of The Open Spanish. Why not (after 18.Õxf2 ©xd4 Black is a pawn up), which looks less harsh on the eye? Gambit, Everyman, and New in Chess almost always avoid using a full stop, thus keeping classical grammar fans happy. Here’s an Everyman bracket to demonstrate

the point (The Triangle System, Ruslan Scherbakov, 2010, p. 294-295): ... (still trying to pose problems; 17...©xf3 18.©xf6+ gxf6 19.Ãxf3 and 17...Àd3+ 18.®f1 Àf4 19.Õe1 are okay for White; instead, continuing the pursuit by 17...h6!? is interesting, as the white queen can’t find shelter in its own camp – 18.©d2? Õd8 19.©c1 Àd3+ wins – but 18.©h5+ g6 19.Àd2! gxh5 20.Àxe4 Àxe4 21.Ãxh5+ ®e7 22.Ãb4+ c5 23.Ãf3 holds the balance) ... Phew! They may have used everything else, but there are thankfully no full stops. Now let’s get back to the essentials. It’s an amazing book! Go for it! Marian Petrov Grandmaster Repertoire: The Modern Benoni Quality Chess 2013 Marian Petrov’s monograph is radically different from earlier treatises on the same opening. Fashions have come and gone, so the 2013 publication The Modern Benoni reflects this. In my youth, White typically met the Modern Benoni with either the tricky Ãg5, the wild f2-f4 and e4-e5 (the Mikenas) or more soberly with the classical lines (based around Àf3 and Ãe2). Later on, the spacegrabbing f2-f4 combined with the disruptive Ãb5+ seemed to put the whole set-up under a cloud. Indeed, so much so that many Benoni fans would only attempt to play this opening if White played an early Àf3, blocking the f-pawn. Those days are long gone but, as f2-f4 is still quite dangerous, a quarter of the present work is used demonstrating that Black is fine. More recently, in an earlier GM series book, Avrukh recommended the solid g2-g3, which, for a while, gave that line a boost. Nowadays it’s the deployment with Ãd3 with

h2-h3 (the Modern Main Line), and an early Ãf4 that have been in vogue. What next? The biggest change is that of ‘quality’, as the Quality Chess team have set their standards very high. Perhaps the most striking feature of the whole Grandmaster Repertoire series is the incessant urge to find novelties. There are loads of them here in The Modern Benoni. Clearly Petrov has worked hard at checking through what is known, asked a few questions, and then sought to add his own touch. Typically it’s in the early middlegame where he suggests alternative plans. He patiently explains why a certain manoeuvre works, or doesn’t, when a certain strategy is appropriate, or not, and how the tactics fit in. You can find many examples of deep and original analyses, all well explained and presented, but the book never comes across as heavy-going. 1.d4 Àf6 2.c4 c5 3.d5 e6 4.Àc3 ed5 5.cd5 d6 6.e4 g6 7.Ãd3 Ãg7 8.h3 0-0 9.Ãg5 Õe8 10.Àf3 c4 11.Ãc2 b5 12.0-0

This is recommended by John Watson in his recent A Strategic Chess Opening Repertoire for White (Gambit 2012).

offer throughout. So there is more than one way to play the Modern Benoni like a Grandmaster! There are only a couple of negative aspects to mention. The first is that there are too many full stops in brackets (see the Open Spanish for my observations). Secondly there is one line that is absent:

MP stops here, considering Black to be better, dark squares and queenside potential being worth more than a pawn. This may be a little optimistic, but he certainly has enough compensation, for example: 16.a3 Àc5

Polak-Padurariu, Leiden 2012. Despite this unfortunate oversight, MP has succeeded with his debut

in the world of chess writing. His own playing experience in his pet-opening is a plus, but his liking for this system doesn’t lead to any noticeable bias towards Black. It’s ideal for ‘average’ players and upwards. If the Benoni is part of your repertoire, with either colour, it’s definitely worth getting this ‘modern’ ‘quality’ book. Viktor Moskalenko The Perfect Pirc-Modern New In Chess 2013 I always enjoy Viktor Moskalenko’s books, as so much seems to happen on each page! The game segments are bursting with ideas, statistics, plenty of helpful explanations, all sorts of symbols, and analysis from various sources including homegrown. New moves and concepts abound. I love the photos, the historical figures, the quotes and anecdotes. Open up the book at random, when you’ll see what I mean! All this, and more, makes for a highly entertaining read. The bulk of the book consists of 37 fully annotated main games, almost half being his own. A sure sign that he has the experience and erudition from which we can all learn. Moskalenko takes a pragmatic approach with move orders that cre-


ate problems for the opponent, for example the following one against the popular 150-Attack. 1.e4 g6 2.d4 Ãg7 3.Àc3 d6 4.Ãe3 c6!? 5.©d2! b5!?

Black has decent counterchances. Janev-Moskalenko, Barbera del Valles 2005. It isn’t by any means a treatise on the pure ‘Modern’, nor, on the other hand, can it be considered as a ‘Complete Pirc’ (The Pirc in Black and White by James Vigus, Everyman 2007, was almost twice as thick). One could instead think of a ‘hybrid’ approach with Moskalenko often switching from the former to the latter, depending on circumstances. In certain chapters it’s inevitable that the author has to go into great detail in the traditional main lines (for example in Chapter Three, covering the Austrian Attack with 5...0-0). It’s essential for the stronger elements amongst the potential readership, and this book is aimed at a wide spectrum. As in his 2010 The Wonderful Winawer, the addition of little icons (which highlight key sections) with the titles Weapon, Trick, Keep in Mind, (a new one) Puzzle, and even Workshop, is a great boon. This process lightens up the content (very welcome in the Austrian) and makes for a series of handy memory aids. Although the author has toned down the wilder side of his infectious humour (see The Fabulous

Budapest Gambit from 2007 for many examples), his enthusiasm for chess is omnipresent. I wasn’t convinced however by the need for the sub-title ‘Strategic Ideas & Powerful Weapons’. The punchy title, the name of the author, and the Foreword by Vasily Ivanchuk are already enough information to get folk interested. The back cover does highlight some of the strong points, amongst which are ‘...the ideas and plans that really matter, the various pawn structures and how to handle them, tricky transpositions: opportunities and risks...’ and so on. The selection of appendices is now a permanent and welcome feature of all New In Chess publications. There is no doubt that this will help one’s research. However I can’t understand why the ‘explanations of Symbols’ page is hidden away in there on page 246. I would suggest placing this, in future, in the vicinity of the introduction. It’s actually on the plus side that the book isn’t too thick. It’s much better to hold 250 pages chock-ablock with high-quality original work, rather than a 1000-page database print-out of old hat. Viktor has done it again. Bravo! Put it on the buy list.

He prefers to have no pawn to having a weak pawn on d6. The pair of bishops give Black ample compensation. 16.cd3 Àa5 17.Àbc3 Àb3 18.ab3 Õe8 White is a pawn up, but both d3 and (especially) b3 are weak. Black is very active along the diagonals and the open c- and e-files.

Solutions The pros are: the queen’s bishop enters the struggle, the centre is opened, Black has active counterplay. But, if White plays accurately, the isolated queen’s pawn on d5 can become a weakness in any ending that may arise. 16.de5 Àce5 17.Ãe4 ©h6 17...d4!?. 18.Ãd5 ®h8 19.h4 Àf3 20.Ãf3 Àe5 21.Ãg2 Ãg4 22.©a4Ç and White went on to win.

Black is the exchange up. White has one pawn for the exchange. Additionally, his bishop on d6 is strongly placed and Black’s rooks have difficulties to become active. White’s 3 vs 1 pawn majority on the queenside can eventually become dangerous.
