World champion Viswanathan Anand bounced back with an emphatic victory over Norwegian Magnus Carlsen in the third round of the Morelia-Linares chess tournament in Mexico.
Anand, who started off with a victory over Alexei Shirov of Spain, played his third decisive game on the trot after losing the second round game against Morelia-nemesis Levon Aronian.
The victory over Carlsen kept Anand's score with black at 100 per cent and also helped elevate himself to the sole second spot on two points out of a possible three.
Former World champion Veselin Topalov of Bulgaria came up with an impressive preparation to down overnight joint-leader Vassily Ivanchuk of Ukraine. Bulgaria's best player emerged sole leader on 2.5 points following the victory.
The third place is jointly held by Ivanchuk, Aronian and Peter Leko of Hungary, who all have 1.5 points each.
Teimour Radjabov of Azerbaijan, Shirov and Carlsen are now joint sixth with a point each in this Category-21 event being played on a double round-robin basis between eight players.
Anand outclassed Carlsen in all departments of the game. Recently during the Corus chess tournament the Indian ace had beaten Carlsen also with black pieces but at that time Carlsen had a few drawing chances that he missed amidst wild complexities.
The third round match, however, was different, as Anand played in copybook fashion in the Semi Slav defense and the Moscow variation failed to yield anything worthwhile for Carlsen.
Exchanging the queens, Anand won a rook for bishop and the technique shown by Anand thereafter was a treat to watch for the spectators.
With awesome ease, the world champion liquidated to reach a winning position that involved slowly pushing the white king away from one of the supported pawns. Carlsen resigned after 59 moves.
Topalov also displayed high quality entertaining chess that he is known for the world over. Playing the white side of a Sicilian Najdorf, Topalov went for the English attack and uncorked a fine Novelty on the 16th move to leave Ivanchuk in a spot of bother.
By the 20th move itself, the Bulgarian was ruling the roost and Ivanchuk could only find solace in a pawn sacrifice after which Topalov reached a better endgame. It was technique-Topalov thereafter that completed the formalities in 46 moves.
Shirov, had to defend for some time against Leko but the Latvian-born Spaniard was never in any serious troubles in this Najdorf defense game. Leko went for a quiet set-up and after regulation exchanges the game was eventually drawn after 37 moves.
The other game of the day between Aronian and Radjabov also ended in a draw in just 24 moves.
Results round 3: Magnus Carlsen (Nor, 1.5) lost to V Anand (Ind, 2); Veselin Topalov (Bul, 2.5) beat Vassily Ivanchuk (Ukr, 1.5); Peter Leko (Hun, 1.5) drew with Alexei Shirov (Esp, 1); Levon Aronian (Arm, 1.5) drew with Teimour Radjabov (Aze, 1).
