World number two Viswanathan Anand kept himself in reckoning for his sixth title on the trot, winning the sixth game against Grandmaster Teimour Radjabov of Azerbaijan in the Grenkeleasing World Rapid championship at Mainz Classic Chess.
With scores tied at 3-3 in the eight-game contest, the stage is set for a nail-biting finale, reminiscent of 2003 edition when the Indian came back from behind three times against World's top rated women Judit Polgar to eventually take the match on the final day.
Anand will be hoping for an encore but Radjabov is certainly proving out to be one of the toughest contestants for the Indian in his own forte - the rapid chess.
Anand has so far played three games with white, scoring just one point while with black his performance has been much better in which he netted two points out of three games.
It turned out to be a similar story in the other big match being played under Chess960 rules in which the position of the pieces is shuffled just before the start of the game.
After another engrossing day here, Russian GM Peter Svidler and Armenian challenger Levon Aronian remained tied at 3-3 score with just two games to one.
The third day provided one victory each for the contestants of this Chess960 world championship match.
In the Ordix Open being played simultaneously, Chess 960 junior champion P Harikrishna showed tremendous fighting spirit to win all the five games of the opening day.
Showing no signs of tiredness despite playing 19 games in four days prior to the Ordix Open here, Harikrishna gave a fine lesson to Grandmaster Sergey Erenburg of Israel in the fifth round game to be among nine leaders.
Others in the lead include former world champion Rustam Kasimdzhanov of Uzbekistan and two-time world junior champion Shakhriyar Mamedyarov of Azerbaijan.
Anand knew he had to win the sixth game to remain in the match as a draw or a loss would have put Radjabov in command because the latter already had a full point lead to back him.
The opening was a Semi Slav defense and for once Radjabov did not go for his pet complexities, opting for a more positional variation.
As a result, Anand equalised comfortably and unleashed an attack on the white king forcing Radjabov to enter a slightly inferior endgame after which it was a treat to watch Anand who marched his king side pawn to score a smashing victory in 46 moves.
Earlier, Anand started the third day with scores tied at 2-2 and was hoping to do better with his white pieces.
However, as the fifth game progressed the Indian ace was in for a big shock as almost nonchalantly, Radjabov got the dynamics rolling in his favour after employing the Sicilian Sveshnikov for the third time in this match.
Playing one of the main lines, Anand got no advantage and in his own words "was worse barely two moves out of the theory".
Radjabov, to his credit, carried out his endgame plan to perfection after getting two passed pawns and Anand lost a piece for effectively no counter play. Interestingly, this game also lasted 46 moves.
Results: V Anand v/s Teimour Radjabov 3-3; Peter Svidler v/s Levon Aronian 3-3
