THE BRITISH Chess Championship in Hove has resulted in a shared title, the vic- tors being Michael Adams and Matthew Sadler. The tournament proper produced a deadlock between Adams, Sadler, Miles and Emms. The British Chess Federation then instituted a play-off, but Adams and Sadler scored equally well and it was decid- ed to share the championship title between them. Although Adams could not exceed Sadler's score in the play-off, he did have the satisfaction of winning their individual game.

Adams's style, securing his queen's flank and preparing play against Black's shattered pawns on a6 and c6. Established theory though recog- nises the sharp alternative 14 Re2 as in the game

An excellent example of the kind of patient tournament technique which garners points.
