Chess

By PHILIDOR No. 197. K. S. HOWARD and ALAIN WHITE BLACK (8 men)

WHITE (10 men) WHITE to play and mate in two moves; solution next week. Solution to No. 196 (Le Grand): B—R 5, no threat. If Black moves either knight he is mated by Kt—R 3 or K 6 accordingly; whichever pawn he moves. White blocks it (still no threat) and Black . must commit suicide, e.g., 1 . . • Px RP; 2 R—R 2..

1 P—Kt 6; 2 R—QKt 2. I Px BP; 2 R--QB2, etc. In short, 'dolce far niente.'

• Man bites dog incidents are as popular in chess as they are everywhere else; this week's game is an out- standing example, since not only is Tal defeated by an attack entirely in his own style but also it occurs when he is playing the Sicilian, a defence against which he has won so many brilliancies himself.•It is only fair to add that the game took place fairly soon after his unexpected and crushing defeat in his return match with Botwinnik: this and his bad health at the • time meant he was well below his: best. The winner . is a brilliant attacking player not, quite consistent enough to reach the very top.

White, R. NESCHMETDINOV, Black, M. TAL. Opening.
