Viswanathan Anand must win the sixth game of his match against Anatoly Karpov if his hopes of becoming the world chess champion are to stay alive. After a draw in the fifth game, Karpov maintained his lead and now needs only a draw in the final game to hold on to his Fide world title. A win for Anand, who will be playing White, would take the match into a series of quick-play deciders.

Both men approached the fifth game with considerable caution. Karpov knew that he could finish the match at once by winning the game, but he did not want to risk losing his lead. Anand knew that his best chance to save the match would come with the white pieces in game six, but he first needed not to lose game five. The result was a game in which Karpov maintained a nagging pressure from the start, but it never really looked like assuming the sort of proportions when he could claim to have serious winning prospects.

Perhaps the most interesting moment came with Anand's 19...g5, a brave and potentially weakening move to drive the White queen away from the vicinity of his king. Karpov's response was to exchange queens and hope to exploit the weakness of the f5 square in the endgame, but Anand held the draw without great difficulty.

White: Anatoly Karpov

Black: Viswanathan Anand

When this match is over, the real business of the world championship will begin. If Anand manages to win, negotiations seem sure to begin for a proper match for the world title between him and Garry Kasparov. Not a chancy knock-out tournament with a six-game final, but a good, old-fashioned contest over 20 or 24 games lasting a couple of months.

If Karpov wins, however, the matter becomes more complicated. First we shall hear renewed protests about Karpov's easy ride in the current event, in which he was given a bye directly into the final. Indeed, the campaign to discredit both the new Fide title and Karpov personally has already begun. Sadly, it looks as though the long-running chess wars are still some way from a negotiated peace settlement.

Hastings: Matthew Sadler coasted into first place in the Premier Tournament at Hastings, drawing his last two games to finish one-and-a-half points ahead of the field. Final scores: Sadler 7; Relange and Rozentalis 51/2; Tkachiev 5; Plaskett 41/2; Nunn and Hebden 4; Rausis 31/2; Ward and McShane 3. We shall be catching up on the games from this event next week.
