WHITE to play and mate in two moves: solution next week. Solution to last week's problem by Mansfield: Q-B 8, threat B-K 4. 1 . . . B-B 7 ch; 2 B-Kt 7. 1 . .. B-K 8 eh; 2 B-Kt 2. 1 . .. K-Q 3; 2 Q-R 6. 1 .. , K-

B 5; 2 B-K 5. Attractive cross-checker with two flight squares thrown in. * This week's game is a far-sighted and imaginative attack by the brilliant but erratic grandmaster, Alexan- der Tolush; the strength of the attack is far from obvious at first sight, and deep insight as well as con- siderable courage must have been needed to undertake it. White might just have escaped (though he would have been lucky to do so), but-moved perhaps by one of these obscure but not uncommon suicidal impulses that occur just as one is emerging from one's difficulties -he abandoned his natural line of defence and at once fell victim to a combination of great brilliance.

White, BaRTOK (Yugoslavia). Black, TOLUSH (USSR). Opening, Dutch. Europa Cup, Vienna, 1957.

(a) Here, or on next move, 51-Kt 2 should he played, followed by Kt-Q 2 and P-K 4. Method adopted is too slow and leaves White's Q Kt badly pieced.

(5) Neatly exploiting position of Kt on R 3, since 12 P x F, P x P; 13 Kt x P? loses to 13 Q-K 21 (r) While this move leads to a violent attack by Black, it is hard to find anything satisfactory: White has drifted into a bad position. (4) Very fine-much stronger than the obvious P-K R 3.

(e) 20 P-K B 4 is better though after 20 ... P x P e.p.; Black's game is preferable.

(1) 21 P x P, P x P; 22 Kt x P. Kt (3)-Kt 5;'23 Kt-R 5, Q-Q B 2! threatening R-R I and Kt-B 6 eh or 23 P-K 3, Kt-B 6 eh; 24 13 x Kt, P x B; 25 K-R 1. K x Kt; 26 P x R, Q-R 3 or 21 P x P.

B X R; 29 R-Q R-IC 8 ch; 31) Kt x R,Q x K1 eh; 31 H-B I,

Q x R. These variations show the force of Black's attack.

(g) Here 24 . . . Kt (3)-Kt 5!, threatening Kt x K P is even stronger.

(h) White threatened R-K 8. (I) White might save the game by Q-Q 7 ch, since after 33 .. . R-B 2; 34 Q-Q S he should draw the ending. Now he gets a shattering blow. (J) 37 R is R, Q-K 8 ch; 38 R-B 1, P-B 7 ch; 39 K-Kt 2, Q-K 5 ch; 40 K-R 3, R-R 4 mate. (k) A problem-like finish: 39 R x R, Q is 11) mate, or 39 B is Q, P is Its.Q mate.
