Having done the hard work, Viswanathan Anand fumbled and lost to Sergey Karjakin of Russia in the sixth round of Shamkir chess tournament here on Saturday.
Playing the black side of a queen's gambit declined, Anand came up with some spectacular preparation that should have been good enough for a draw but Karjakin pressed hard where it mattered and went on to secure a rare victory against Anand.
Karjakin joined Magnus Carlsen of Norway in lead on four points out of a possible six following an unexpected victory.

Anand shares the third spot with Ding Liren, Topalov, Radjabov, Grischuk and Topalov all having three points each while Mamedyarov and Giri are struggling on two points from six matches.
It was not a game for Anand to lose, a long opening variation where in the Indian had done the hard work led to an absolutely equal endgame with a knight and a double rook. Karjakin however pressed on for a long time in an equal position and Anand could not find the right way out.
As it happened in the game Anand lost a pawn on the king side and called it a day.
