World Champion Viswanathan Anand suffered a shock defeat at the hands of Etienne Bacrot of France in the fourth round of the Pearl Spring Chess tournament here.
Just when he was sitting pretty with a black-piece win against arch-rival Veselin Topalov of Bulgaria, Anand was in for the biggest surprise of this season as Bacrot, once the youngest Grandmaster in the world, played energetically to catch the Indian ace off guard and score one of the biggest wins of his career.
Meanwhile, Magnus Carlsen of Norway salvaged some anxious moments and finally played out a draw with Vugar Gashimov of Azerbaijan, while in the other game of the day Topalov too could not make any headway and had to split the points with Wang Yue of China.
With six rounds to come in this six-player double round robin tournament, Carlsen took his tally to three points and he is now followed by Bacrot a half point behind. Anand now stands sole third on two points while Topalov, Wang Yue and Gashimov are sharing the fourth spot on 1.5 points apiece.
It turned out to be a tough day for Anand in the Slav defence game wherein the Indian went for a well-analysed piece sacrifice variation. As is typical of the opening, Anand got four pawns in exchange for his piece, but the nature of black pawns remained fragile.
To Bacrot's credit, he went for a relatively less played system, which should have been equal but Anand was caught off-guard in the exchanges that took place intermittently leading to a two pawn deficit for the Indian.
