WHITE (6 men) to play and mate in two moves; solution next week.

Solution to last week's problem by Kt-Q 2. 1 P-B 4; 2 B-Kt 7.

Occasionally one sees games which leave a feeling at the end, 'Well, why did Black loser This is a game of this kind. Black plays one of the most popular defences of the day, follows the best authorities, and yet never seems to succeed in equalising. 1 do not know why he lost this game: perhaps chess is a win for White after all—or perhaps it was just that Keres was White.

White, P. KERES Black, E. GEREBEN Opening, K. Indian Defence.

Played in Amsterdam team tournament, 1954.

(6) If 6 P-Q 5, then 6 . . . P-K 3; and White's centre gets disrupted.

(c) Black's difficulty is to find a good square for queen: if 10 . . . Q-K R 4; then 11 P-K R 3 gives White the better position.

(d) It' 12 ... Q-Kt 3 ch; 13 K-R 1,Q x P; 14 Q R-Kt 1 White has more than enough positional compensation for the pawn. I can find no wholly satisfactory move for Black hero—text may be as good as any.

19 Kt x P ch winning queen.

(j) Beginning a very fine attack against which there seems to be no adequate defence: notice how he refrains from driving back the knight and is later able to exploit its exposed position. (g) 17 ... Kt-R 3; is better, but after 18 B-B 3 White still has the superior game. (h) A mistake: he tailed to see that after 23 R-B 4 he could not play 23 ... Q-K 4; because of 24 P x PI winning at least two pawns. However, even after 22 . . . Kt x E: 23 B x Kt, P x B; 24 Kt x P. Black loses K P (or worse) with hopeless position. (0 Or 24 . . • Q-R .1; 25 P x P, P x P; 26 Kt x P, winning easily. (I) Black having railed to resign, White finds the most rapid method of disposing of the remains of his position, (k) The threat or Q-R 7 eh and Q-R 8 mate is too mach for even his op•imism.
