Armenian Gets 4th Round's Sole Win

LAS VEGAS -- Top-seeded Vladimir Kramnik was forced into a tiebreaker, and only one player was able to win in the fourth round of the World Chess championship.

Vladimir Akopian of Armenia, the 31st seed, defeated veteran Bulgarian grandmaster Kiril Georgiev, seeded 23rd, in an endgame that lasted 90 moves Tuesday.

Kramnik tied against Veselin Topalov of Bulgaria, while sixth-seeded Vassily Ivanchuk of Ukraine tied against Liviu Nisipeanu of Romania.

Second-seeded Alexei Shirov of Spain, who won a marvelous game Monday, secured a draw Tuesday against 10th-ranked Nigel Short of England and therefore earned one of the eight spots in Thursday's fifth round.

The other six matches saw draws for the second straight day. Two-game sets of tiebreaking matches will be held Wednesday.

The Federation Internationale des Echecs tournament is being held at Caesars Palace and the winner will receive $660,000 of the $3 million prize fund.

Judit Polgar of Hungary, the only woman remaining in the tournament, was on the verge of elimination in her game with Russia's Vadim Zvyaginsev. Polgar was forced to sacrifice a bishop but her counterattack forced the Russian to give up a piece of his own.

The youngest player, Sergei Movsesian, 20, of the Czech Republic, managed a draw against Alexei Fedorov of Belarus, the third seed. Fedorov gained an early advantage, and Movsesian was forced to give up his queen for only a rook and knight.

Fedorov was winning handily but played inaccurately. Movsesian, the 27th seed, was able to build a fortress and salvage the draw.

The other four games each ended in 30 moves or less.

England's Michael Adams, the fifth seed, played an uneventful draw against Alexei Dreyev of Russia. Israel's Boris Gelfand did the same against Alexander Khalifman of Russia.
