The NIIT brand ambassador drew his fifth round game after a long drawn out battle, lasting 80 moves, against Russian champion Peter Svidler.

Anand now has three points from five games.

Others leading the field with him are Vladimir Kramnik, Veselin Topalov, Michael Adams and Peter Leko.

Adams and Leko played out 101 moves in a  game that for a some time looked like going Leko's way. Ultimately Adams managed to take a half point and ensure a bunched up leader group.

There is no game on Friday and in the sixth round on Saturday evening, Anand will have white pieces against Alexey Shirov, against whom the Indian mind champion has a heavy score with white pieces. He also beat him in the finals of the NIIT-sponsored World Championships in Teheran in December 2000.

Anand, who realized he had missed a win against Bologan in fourth round, went all out against Svidler. The game was a Ruy Lopez way and Anand made two pawn sacrifices on the 19th and 20th moves, which gave the game an interesting twist.

Anand tried to go for his rival's bishop, but Svidler handled his defence well. He got back one of the pawns, and then it was Svidler who was pushing the Indian. Anand managed to defend perfectly in a queen and pawn ending, where the Russian had an extra pawn on the Queen side.

As Svidler tried to promote his pawn, Anand looked for a draw via perpetual checks. In the end, Anand held Svidler at bay and a draw was agreed after 80 moves.

There were two just decisive games, even though many of the fifth round clashes were long battles. One of the upsets was veteran Jan Timman beating the 2003 Dortmund champion Viorel Bologan. The game lasted 59 moves from a French defence in which Timman had black.

In the only other decisive game, Vladimir Akopian beat Ivan Sokolov in 37 moves of Ruy Lopez game. Vladimir Kramnik with black drew with Alexey Shirov in 25 moves of a Sicilian Rossolimo, while Zhang Zhong of China with white managed to stave of defeat against Evegeny Bareev, who was ahead in material from a French defence. Loek Van Wely and Veselin Topalov played a draw from a Nimzo Indian in 26 moves and Leko was held by Adams in a marathon Ruy Lopez after 101 moves.

Pairings for Round 6: Adams v Bareev; Kramnik v Zhong; Anand v Shirov; Timman v Svidler; Topalov v Bologan; Sokolov v Van Wely; Leko v Akopian.

Results of round 5: Leko drew Adams; Van Wely drew Topalov, Svidler drew Anand; Akopian beat Sokolov, Bologan lost to Timman, Shirov drew Kramnik, Zhong  drew Bareev.

Standings after Round 5: 1. Topalov, Anand, Leko, Kramnik and Adams 3.0 each; 6. Van Wely, Svidler, Akopian and Bareev 2.5 each; 10. Sokolov, Bologan, Shirov, Zhong and Timman 2.0 each.
