World Cup champion Vishwanathan Anand regained the joint lead after a crushing victory over former world champion Anatoly Karpov of Russia in the fifth round of 65th Corus chess tournament in Wijk Aan Zee, the Netherlands, on Thursday.
Latvia-born Spaniard Alexei Shirov ripped apart the defences of Braingames champion Vladimir Kramnik of Russia and joined Anand and the world's best woman player Judit Polgar at the top of the table on 3.5 points.
Following the three leaders are Dutch GM Loek Van Wely and defending champion Evgeny Bareev of Russia on 3 points each while Kramnik, GM Vassily Ivanchuk of Ukraine and GM Alexander Grischuk of Russia trail them by half a point.
In the Grandmaster "B" tournament, former world junior girls' champion Koneru Humpy suffered another defeat, outsmarted by top seed Grandmaster Zhang Zhong of China in a long-drawn game.
Zhong (4.5 points) maintained his sole lead with the victory. The high point of this section was the victory of 15-year-old local hope Daniel Stellwagen, who beat GM Arkadij Naiditsch of Germany.
An International Master, Stellwagen is now strongly gunning for a Grandmaster norm in the event, having tallied 4 points.
Anand has played more than 80 games against Karpov in various tournaments and holds a plus score against the legendary player. Yesterday too, the Indian ace did not disappoint his fans, playing an exciting game.
Playing white, Anand opened with the king pawn in the sharpest advance variation and faced the Caro Kann that has been serving Karpov well. The middle game was full-bloodied as Karpov sacrificed a piece for three pawns in the initial stage and threatened to roll down the pawns with Anand's King left in an open position.
Once the dust settled down a bit, Anand made steady but definite progress on both flanks. On the 27th move the Queens got traded and thereafter Anand gave little respite to Karpov.
On the 44th move, Karpov finally called it a day.
Anand's brilliant victory was overshadowed to some extent by Shirov's triumph over Vladimir Kramnik for whom this was the second loss in the event, having gone down to World champion Ruslan Ponomariov of Ukraine in the second round.
Kramnik has, in fact, had most number of decisive games so far, with two victories and two losses.
Shirov is the only player in the world who has troubled Kramnik repeatedly with his magical tactical abilities and he proved it yet again. With white, Shirov faced the Sicilian Sveshnikov that has been revived a great deal by Kramnik himself in the past few years.
Kramnik came out of the opening with a dynamically balanced middle game. But as the game progressed the Russian missed the thread of the position, blundered a pawn and lost rather tamely in the end. This game too lasted till the 44th move.
Loek Van Wely accounted for Bulagrian GM Veselin Topalov in an astonishing manner. The Closed structure against the Sicilian gave Topalov, white, a slight advantage as he held firm control in the centre.
Van Wely kept himself much in the game with right deployment of pieces on the kingside and when Topalov went astray by avoiding a forced drawing sequence, he struck hard to create decisive mating threats. Topalov resigned after 37 moves.
The youngest participant in the fray, Teimour Radjabov of Azerbaijan got the better of Dutchman Jan Timman, who misplayed a roughly level endgame.
The white pieces gave Radjabov some initiative after the opening moves of a Queen's Indian defence but Timman sorted out his problems with routine exchanges. However, on the 35th move Timman worked on an illusionary attack and sacrificed his knight for just one pawn. Radjabov defended well to register his first victory in the event in 54 moves.
Overnight leader Judit Polgar achieved nothing with her white pieces against Ivanchuk and took a draw in the middle game out of an English opening by transposition.
Grischuk drew a well-contested game against Ponomariov.
The other game between Polish GM Michal Krasenkow and Bareev also finished in a draw.
