Chess no. 365

Dr C. Goldschmeding (Sunday Citizen; 1st prize, Ring Tourney for two-movers, 1966). White to play and mate in two moves; solution next week.

Solution to no. 364 (Hartong); Q - Q R 2!, no threat. 1 . . . Q moves: 2 Q- R 6 or Kt X K P.

1 . . . R moves; 2 K x B P. 1 . . . Kt moves; 2 K X Kt P. 1 ...B moves; 2 Bx P or K-R 4.

I P-Q Kt 5; 2 B-R 4. 1 P-B 5; 2 Kt - Kt 4. 1 . . . P - Q 5; 2 Kt X K P. 1 . . . P - K 5; 2 B x P. 1 . . . P - K Kt 5; 2 K - R 4. Entertaining and original problem.

The following fine game was won by Taimanov in the Havana tournament; Taimanov, equal second behind Larsen, lost only one game-but it was the decisive one, that against Larsen. An interesting feature of this game is the sacrifice of the exchange; it seems to me that players are much more ready to make positional exchange sacrifices than used to be the case.

White, Hennings. Black, Taimanov. Opening, Sicilian. (Havana, 1967.)

13 P x 11 Kt x P. Black has only one pawn ter the exchange, but (a) White will not in the end be able to defend his weak Q side pawns; (b) Black has control pf the centre; (c) There is no scope for the White rooks. 14 Q - K 1
