Anand faces Peter Svidler challenge next

Anand secured a fantastic victory with black, but also missed an opportunity and had to be content with a couple of sedate draws in the first four rounds of the competition.

Four players8212;Levon Aronian of Armenia, Russians Alexander Morozevich and Alexander Grischuk and Israeli Boris Gelfand8212; share third spot on 2 points apiece.

Svidler and Peter Leko of Hungary are currently at the bottom of the tables on 1.5 points each. Still 10 rounds remain in the premier event.

Anand had a good start which could have been excellent had he won from a much better position against Morozevich in the previous round.

After starting out with a draw against Gelfand, Anand had tormented Aronian and then drew a difficult endgame against Kramnik.

The Indian could have been in sole lead and so could be Kramnik, who also misplayed a promising position against Grischuk in the fourth round.
