Viswanathan Anand [Images] showed immaculate preparation to score a stunning win over Lev Aronian in the second round of the World Chess Championships in Mexico City on Friday. Also scoring a finely crafted win was his arch-rival Vladimir Kramnik, who beat Alexander Morozevich in another second round.

The other two games ended in draws with Peter Svidler splitting points with Peter Leko and Boris Gelfand held by Alexander Grischuk.

With a win apiece for Anand and Kramnik, the stage was set for a riveting third round clash between the two leaders. Anand, who has won 18 times against Kramnik and lost 14, will have the advantage of white pieces. The two have also drawn 86 times.

Kramnik beat Morozevich in a mere 27 moves following a Catalan opening.

In the first round Anand started the championship with a draw against Gelfand, while Kramnik drew his first round with Svidler.
