In the eighth round of the Smith & Williamson British championship in Hove, Tony Miles played a cautious draw with the white pieces against Michael Adams, which let Tony Kosten overtake both of them and move into the sole lead thanks to a vigorously played win against Joe Gallagher. With three rounds left to play, the leading scores are: Kosten 61/2, Miles, Adams, Sadler, Emms, Ledger 6; Ward, Hebden, Sashikiran, Summerscale, Speelman, McShane 51/2.

Here are two games from earlier rounds. In the first, the tournament favourite scores a quick win against the Sicilian. After 13.g6, Black realised that 13...hxg6 14.h5 would give White a strong attack, but what she played was hardly any better.

The next is a better-contested battle, which White lost by getting carried away with his own attacking ideas in a superior position. After 28.Rae1?! White may have expected 28...fxg4 when 29.f5+ followed by fxe6 gives a formidable attack. But 28...Rd2+! invited 29.Kh1 Bd4! 30.Qxe6+ Qxe6 31.Rxe6+ Kf7 when Black wins a piece.

Ledger must have hoped for 29...Bd4 when 30.Rxe2! Bxe5 31.Nxe5+ is good for White, but as the game went he did not obtain enough for his piece.
