169: Black plays very solidly now because he is leading. But white tries every way to complicate the game.

191 lets white live, however black ’s territory remains enough. Moves 194 - 202 are white ’s privilege. However white does not gain a lot if black plays 207 at the good point of 208 instead of the bad point 207.

If Black plays 143 as in diagram 6, the continuation to 147 follows and white has to connect with 148. If White were to answer 149 in the upper right corner, then Black would get the big play at 150 instead. By 153 (which might also be at A) if black can retain the lower right corner then white is far behind in territory.
