Chess: Grandmasters throw a spanner in works

WHAT makes life difficult for the fancied runners in the Interzonal in Biel, Switzerland, is the presence of several grandmasters who have little hope of taking a top place, but whose aggressive styles threaten even the best. One such is the Australian Ian Rogers, who played the best game of round five.

In the Benko Gambit, which Rogers adopts here, Black usually finds compensation for his pawn along the Q-side files. White's 5. e3 and 7. a4 is designed to make that difficult, but allows another plan of central play. After luring the c-pawn to b5, it is natural to play e6 and exploit Black's central pawn majority; Rogers combines that idea with a K-side attack.

When White decided to fight for the initiative with 25. Nxc5 he immediately succumbed to a very neat mating finish. After 26 . . . Bxg2+] 27. Kxg2 Rxf2+] Black forces mate with Qg3+ whether the rook or king captures on f2.

After five rounds in Biel, the lead is shared by Anand, Bareyev, Gurevich, Salov and van der Sterren on 4 points. Jon Speelman has 31 2 .
