Chess BLACK (7 men)

WHITE (7 men)

WHITE to play and mate in two moves: solution next week. Solution to last week's problem by' Penis:

Q-Kt 7! threat Q-Q 5. I . B x P; 2 Q-Kt I (set Q-Kt 6). 1 K x P; 2 Kt-K 5. 1 ... Kt x K P; 2 Kt-Kt 5 (set Kt-B 2). I . Kt x B P; 2 Kt-Kt 2 (set Kt x P). Very elegant problem with changed mates arising from substitution of Q B 5 for K 5 as a flight square for Black king.

Paul Keres is still perhaps the greatest attacking player in the world and there is no one against whom I would less like to have a bad position; in this I speak from fearful experience having_ lost on different occasions in 17 and 22 moves—so my heart goes out to the unfortunate Tolush in the following game. Incidentally, I am by no means sure that White's

attack is sound: on the whole (think it probably isnot' but the position was too difficult for Tolush to cape with in practical play. I have found it, equally, 0° difficult for me to analyse adequately, so readers may try their own analytic skill and find out who should have won. The one thing I am sure of is—don't defend such a position against Keres.

(a) This is a much analysed variation, introduced by Keres S0•!! years ago when he won decisively against Fuderer. Opinions 0, merit have fluctuated up and down a good deal and there doubt that Tolush must have prepared something special agoill'; the attack; but—when one sups with the devil, one needs a 101i. spoon.

(b) A new move. Tal's move 12 Kt-K 4 is normally plaYed and I have no doubt that it was against Kt-K 4 that Tolush prepared—but Keres got his surprise in first.

(c) 12 . . . Kt x P; is met by 13 Kt x PI threatening 12,--Q,..! mate and Kt-B 7 mate. If 12 Q-B 4; then 13 B x K P! Archives) and 12 . . .

gives 15 B x K P; 0-0! [15' 0 Q x Kt; 16 Q x P. R- I; 4, Kt-Q 5!1; and now he gives 16 Kt-B 5, Q x P ch; 17 K.i-K I; P x B (17 .

Kt x 13; 17 Kt-B 3: maybe readers a' improve. (f) 57. . . Q-B 4; 18 Kt-K 4. (g) 18 . . . Kt x R; 19 B x Kt and 20 Kt-K 4 gives While $ winning attack. (/r) 20 .. .

(k) A nightmare of a position for Black! ( 1) He is heavily down in material and White's attack is as gal' as ever, e.g., 29 ... Q-K 7: 30 Q-Kt 4 ch, K-Q 2; 31 B-Ii 4 K x Kt; 32 R-K 1. Extraordinarily daring and comPleir all by Xeres.
