Vladimir Kramnik continued his winning ways in Wijk aan Zee with a powerful victory against Boris Gelfand. With four out of four, Kramnik is now a point ahead of the field. Scores: Kramnik 4; Anand and Topalov 3; Timman and Adams 21/2; Karpov, Gelfand and Polgar 2; Shirov and Nijboer 11/2; Piket, van Wely, van der Sterren and Salov 1.

Kramnik's win was a typically energetic performance, unnerving the usually solid Gelfand by switching his attack from Q-side to K-side and back again, never letting his opponent settle down. The most attractive game of the day, however, came from Michael Adams against the Dutch grandmaster Friso Nijboer.

When White avoided Adams's favourite Marshall Gambit with 8.a4, the game settled into a characteristic type of Ruy Lopez manoeuvring, with White trying to create weaknesses among the black Q-side pawns. Perhaps White had thought 28...bxb5 unplayable because of 29.Nc7, but 29...Qc8! is then good for Black. The real fun, however, came with 30...Nf6! and 31...Nxe4! when both 32.Bxf8 and 32.Bxb8 are met by Qxd5. As the game went, Black's bishop and two pawns were too much for White's rook. At the end, 39.hxg3 Qh4+ leads to mate next move.
