This is PRECURSOR LXXV and is published in August 2000. PRECURSOR is edited by William P. Miesel and is published by unikorn magik. The editorial offices are at 2215 Myrtle Street, Erie, Pennsylvania, 16502-2643 (phone 814-454-8802). PRECURSOR is being published more than three times a year and is sold for $21.00 (U.S.) for three issues. Outside the United States, Canada, and Mexico, three issues are sent Air Mail for $25.00 (U.S.). "N x M Rectangle Divination" is a continuation of Reinhard Miiller's "3 x 3 Square Divination" described in Precursors LXIII & LXV. These articles end with the notation that Reinhard was experimenting with further ideas along these lines but were not yet developed. This article is the results of his experimentation. Before trying to understand this article you'll have to go back and be sure that you are familiar with the previous material. "Reversa-Skill" is Al Thatcher's three-phase variation of Stewart James' "Miraskill." One of the strong features of this routine is that no cards have to be stolen and later returned to the deck - the deck has fifty-two cards throughout. The "Trick With A Week Ending" is another one of Marty Kane's trick using the "Down/Under Deal" with a clever story to go along with it. Even though "The Down/Under Deal" is used, this trick is a quickie because the count is done only once with less than ten cards. Michael DeMarco gives us "Double Or Nothing," another cards and dice trick. The top cards of two packets reveal the numbers on the tops of two dice, and then those numbers reveal the position of selected cards in the packets. One of my favorite plots is the transposition of two cards. Tom Hubbard's, "Whose Card?" is his version of this plot and is performed with a borrowed deck. "Computerized Card Discovery" is another of Warren Stephens' humorous effects. It is all in the presentation - all that the method consists of is Bill Simon's "Business Card Prophesy." Barry Govan's "The Magic Spell" is basically a self-working card revelation in which a spectator spells to his own selected card. Even though this is based on mathematical principles, it does not appear so. Five years ago, while I was working on Paul Swinford's version of the "Seven Card Monte" for Precursor XLIX, I thought of that trick for the first time in many years. I was always planning to develop a version that was impromptu. Here is my version of the "Seven Card Monte" that does not require the use of a double-faced card. While playing around with some of these ideas, I came up with a second routine, "The Ambitious Seven Card Monte Comes Home." This routine combines "The Ambitious Card," "The Seven Card Monte," and "The Homing Card" into one routine. "Conch-A-Doodle-Doo" is one of Ed Eckl's favorite card revelations. Both Ed and I saw someone else perform this basic idea; neither one of us can remember who it was. Can any of our readers help us identify this magician so that we can properly credit the true inventor of this funny bit. William P. Miesel June 1,2000 1
N x M RECTANGLE DIVINATION This is a further elaboration of my "3x3 Square Divination," which appeared two years ago in Precursors LXIII & LXV. I succeeded in generalizing the square to the rectangle. To understand this more elaborate version of the 3x3 Square Divination, it is essential that you are familiar with the versions that came before. 1. The spectator deals out any number of playing cards, face up, in a rectangle with the proviso that the sides of the rectangle must consist of three or more cards. The smallest possible rectangle or square that can be used is 3x3, 3x4, 3x5, 3x6 - 4x4, 4x5, 4x6 - etc. 2. Turn your back to the scene. Now, follow the original "mixing procedure." Ask the spectator to turn over a complete horizontal or vertical row of cards. The spectator repeats this turnover as often as he likes. The "mixed" rectangle should result in a really mixed-up pattern of face-up and face-down cards! Avoid the special mixing that results in all of the cards being either face up or face down. 3. The spectator thinks of any card in the matrix, either a face-up or a face-down card. He turns over only this single thought-of card, a face-down card is turned face up and vice versa. The spectator again performs a few more "turnovers of rows of cards." 4. Turn around and look at the layout of cards and divine the thought-of card in the following manner: Visually, divide the rectangle into 3x3 squares and look for the "odd 2x2 squares" as explained in Precursor LXIII, pp. 13 - 14. Figure #1 depicts an example.
1 2 7 8 13 14 19 20
3 9 15 21
4 10 16 22
5 6 11 12 17 18 23 24
5. First look in the 3 x 3 square 1-2-3 - 7-8-9 - 13-14-15; then in 7-8-9 - 13-14-15 - 19-20-21; following with 2-3-4 - 8-9-10 - 14-15-16; etc. 6. If you occupy yourself with this principle you will find that there are 2 x 2 squares, which belong in two different intertwined 3 x 3 squares. For example: The two 2 x 2 squares (7-8-1314) and (8-9-14-15) are common to the two 3 x 3 squares (1-2-3 - 7-8-9 - 13-14-15) and (7-8-9 - 13-14-15 - 19-20-21). As a result, you have to look into those 2 x 2 squares only once to see if they are "odd" or "even." That characteristic speeds up the process of checking the squares.
