This year's Hastings Congress was quite a good one for our young players. William Hartston at the age of eighteen made the respectable score of 31 out of 9 in the Premier—particularly creditable as he scored o in Q—R 3?, B—Q 4 ! and B—R 2?, B—B 4! the first five rounds and had the determination to come back and score 31 in his last four games ; R. D. Keene in the 'Challengers' also put up an excellent perform- ance in tying for first place with the very promising sixteen-year-old Russian Y. Balashev, scoring 7410.

The highlight for Hartston was undoubtedly his defeat of Gligoric in round 7 ; apart from his excellent play two psychological factors contributed to this result —first, Gligoric after being in the lead with 41/5 had just lost (with White) a key game to Uhlmann in round 6 and secondly Hartston at this stage had 1 6 and was probably underrated by Gligoric. The most important technical point—as Hartston shrewdly points out—was that Gligoric allowed a risky and double-edged variation instead of forcing Hartston to play positionally where his inexperience would have mattered much more.

White, HARTSTON. Black, GLIGORIC. Opening, SICILIAN.

favours—many germs have been woo by both players in it; but, being a highly combinative line, it gives the younger, less experi- enced player better chances than most lines.
