CHESS by Philidor

No. 307. L. CEaratsu (Die Schwalbe, 1939) WHITE to play an mate in two moves, solution next week. Solution to No. 306 (Michel): Kt - 0 51 no threat. r . . KxP; 2R-R4 (set R - B 4). s.. K-B 3; 2 QxKt

This week's game shows a clash between two of the best and most imaginative attacking players of their respective generations in this year's British champion- ship; on this occasion youth triumphed but-as

Milner-Barry demonstrated in other games at Sunder- land-this was not always the case.

Kt-KB3 Kt-KB3

4 Kt - B 3 P-QR3 A very brave line to play against Littlewood; after the present game I feel doubtful whether the attack can be defended-if it cannot, then I am not sure just what Black should do. The alternatives are P - K 3. P - II 3, P - B 4 and B - B 4-none wholly satisfactory. 5 P-K4 Kt 4

7 p_ QR4 Kt X Kt White can always force this by P x P, but it might be better for Black to delay the capture until he does; but if the capture is delayed Black must also reckon with Kt - K 4.

White would have little attack and, with two pawns for the exchange, Black's game would be quite satisfactory.
