PHILIDOR

G. W. Chandler (2nd Prize, B.C.P.S. 1952). White to play and mate in two moves; solution next week. Solution to no. 351 (Casa): K - B IL no threat.

The young players confirmed their growing grip in British chess in this year's championship. Dr Jonathan Penrose, now in the early thirties, con- firmed that he is still in a class by himself by leading for nearly all the tournament and winning with 8f/11 (W6 D5), but of the next four Hartston (second with 8/1I-W6 LI D4) is still at Cambridge, Whiteley (3= with 7) is at Oxford, and Lee (also 7) has only just left Oxford; the veteran Harry Golom- bek, however, who shared third place showed that even at fifty-six it is still possible to play good chess. The following game, won by Lee in the Clare Benedict tournament at Leysin, is a good example of his clear aggressive style.

White, K. Langeweg (Holland). Black, P. N. Lee (England). Opening, King's Indian Defence.
