Chess: Nunn takes it steady

WITH three rounds left to play at Hastings, the early leader, Mikhail Krasenkov of Russia, has been overtaken by John Nunn and only these two players still have a realistic chance of first place. Both men usually have combative and entertaining styles, but in this year's tournament, where only nine of the 30 games played so far have ended in draws, they have looked the steadiest of the players.

John Nunn took the lead in round six with a powerful win against Dibyendu Barua. In the opening, a line of the Four Knights' Game that Nigel Short brought back into serious use, Barua played too simply by exchanging knights on move 6. This gave White a nagging lead in development and the time to open the f-file with 12. f4.

The moves that turned White's promising position into a real attack were 19. g4] opening lines for the rooks and 23. Rg1] choosing the right files to put them on. The lazy way to play such a position is automatic doubling on the f-file with 23. Raf1, but Nunn's move saw far deeper into the possibilities. If Black had met 25. Ng3 with Nf4, White could have played 26. Nf5]? gxf5 27. Rxf4] exf4 28. Bd4 when 28 . . . f6 is met by 29. Bxf6 and the attempt to buy off the attack with 28 . . . Qg6 is most powerfully answered by 29. exf5.

As the game went, White barged through on the open files and finished it off neatly.

By contrast to this smooth performance, Krasenkov's win in the fourth round was a fine piece of bludgeoning. Catching Ian Rogers in a complex line of the Queen's Gambit, the Russian went for tactics from the start. Hanging on to the gambit pawn for long enough to create drastic imbalance, he gave White a huge central pawn majority in exchange for two fast runners on the wing. White's 11. d5?] did not turn out well and Black's pawns soon looked the harder to keep blockaded, but 18. Bg4? was based on a complete miscalculation.

Rogers must have overlooked the neat 20 . . . Bc6, defending against Qd7+ and giving Black time to regain the piece with Qxg2. After that, there was no way to defend the white squares. At the end, the threat is Rxa5 and needing to defend against mates on d1 and e2, there is nothing White can do about it.
