WHITE to play and mate in two moves: solution next week.

Solution to last week's problem by Shinkman: Q-Q Kt I I, no threat. 1 ... K x Q R, 2 Q-R 2.

1 . . . K x K R; 2 B-R 2. 1 . . , B x Q R; 2 Kt-B5.

1 . . B x K R; 2 Kt-Kt 5. The overworked adjec- tive 'charming' really applies for once.

This year is the fiftieth anniversary of the formation of the British Correspondence Chess ASsociation, and this week's game is taken from the Association's magazine, Correspondence Chess. As with all other forms of organised chess, there has been a very great increase in correspondence play since the Association was formed, and it now caters for players of all strengths-readers who like to play chess but cannot find suitable over-the-board opponents might well try the correspondence game.

15 Q-Kt 1 B-B 4 31 K x R R-Q 8 mate 16 P-K 4 Q-K Kt 3 (I) (a) I am a little doubtful whether this highly aggressive defence is quite sound. 5 ... 0-0 is more solid. (b) Too slow. Much better 11 Kt-13 3 meeting B-K 3 with Q-Kt S and B-B 4 with Q-Q 6. Black will recover one pawn, but White should hold the other. (c) 13 Q-R 5, Kt-K 4; 14 P-R 3, R-Q 41 as in game Oakley-Knibbs gives Black the advantage. And if 13 Q-B 3 then Q-Kt 3; 14 R-B I, 13-10 5; 15 Q-Kt 3 Q-B 7! wins. (d) Despite queen exchange, Black still has sufficieni attack to be worth the pawns-and a little more. (e) Much too ambitious. 20 Kt-R. 3 preparing to castle is correct. (f) 22 P x P, B-0 6; 23 Kt-B 4, R-R 8 ch; 24 13-0 I (24 14g-Q 2. Kt-B 5 ch; 25 K-B 3. R-R 6 mate). 7 and st.rins. (g) This fine move is decisive (h) Best chance. If now 25 . . R-Kt 7, then 26 B-K 4 or 25 . . . Kt x B ch; 26 P x Kt, R-Kt 7: 27 K-R I ! R-Kt 8 ch; 28 R-Kt I. (/) Equivalent to resignation, but there is nothing to do. (J) Well and energetically played by Black.
