BLACK (12 men)

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

Solution to last week's problem by Mosely: R-K 2 waiting. 1 . . Kt-Q 5; 2 P-B 4. I ... Kt (B 4) else; 2 R-Q 2. 1 . . .

Kt (Kt 3) any; 2 R-K 5. 1 . . .

WHITE (9 men) P-K 3, 4; 2 Kt-B 6.

1 . . P-B 5; 2 R-R 5. Well-constructed 'waiter' with an added mate given by key move.

Of all the major defences to the Queen's Pawn, the King's Indian gives Black the greatest counter-attacking chances; conversely, of course, it also offers White considerable opportunities. It is, in fact, a defence, like the Sicilian, which it pays to play against opponents weaker than oneself; an opening in which the stronger player can make the game look just too easy, whether he is Black or White, because by more accurate and forceful play he will get his own attack going, and the opponent will fail ever to develop the counter-attack. The winner of this game, Bouwmeester, is one of the best of Holland's younger players.

17 P-B 47 (e) KPxP 34 Resigns (k) (a) White cannot win a pawn here or on the next move, because of the latent threat of Kt x K P after White has taken on K 5 with his knight. '04 Hoping to support the centre sufficiently to avoid having to play P x P or P.() 5. However, as, in fact, he cannot avoid one or other of these moves, text is pointless.

(c) White's queen side advance proves to be quite innocuous and therefore a waste of time. He would do better to prepare immediately to deal with Black's king's side attack. (d) Centre being closed, be now prepares the cLanic advance P-K B 4.

(e) A fatal error leaing to disruption of his king's side. Kt-Kt 3 is correct, sod that when he plays P-K B 4 he can retake with knight. Even as played, 18 B x P would be better.

(‘) Very well played: White cannot now prevent both ops from penetrating his position. loss) K-R 1 is a shade better, but White's position is still (k) Black threatened both 26 ... B-K 5 ch; 27 Kt-B 3, ci X R; and 26 ... B-R 6 ch. (I) 29 Kt-B 4, Q-B 4; is equally hopeless. (1) There is no defence against threat of Q R-K B 1. (k) Black threatens 34.—R x Kt; 35 R x R, B x R ch; 36 R x B, R-Kt 8 mate. If 34 P-R 3, then 34 ... R-Kt 61 and if 34 B-K 3 then 34 R x Kt; 35 B x B ch, Q R-B 3 ch, Striking example of the power of the two bishops.
