Bulgarian grandmaster Veselin Topalov defeated Rustam Kasimdzhanov of Uzbekistan in a hard-fought rook and pawn ending today to retain a two-point lead after seven rounds of the scheduled fourteen-round FIDE World Championship Chess Tournament in San Luis, Argentina.
It was the fifth win in a row for Topalov and his sixth of the tournament. This gives the Bulgarian 6½ points in seven rounds. The only blemish on Topalov's score is a second-round draw against Viswanathan Anand of India. A player is give a full point for each victory while draws are worth a half-point each.
Topalov has a two-point lead over Russian Peter Svidler, who today defeated Judit Polgar of Hungary, the strongest woman player in history. Tied for third with 3½ points each is Anand, who lost today to Alexander Morozevich of Russia, and Peter Leko of Hungary, who defeated Britain's Michael Adams.

The winner of the tournament will be given the FIDE version of the world title. It is hoped that the winner will play the classical world champion, Russia's Vladimir Kramnik, to end a schism in organized chess that dates back to a dispute between FIDE, the governing body of international chess, and then-world champion Garry Kasparov in 1993. Kramnik's claim to the title comes from his defeat of Kasparov in a match held in 2000 in London.
