Anand-Topalov Round 4

Today was round 4 of Anand-Topalov, and it was very exciting! Anand used the Catalan again, and Topalov tried yet another c4 Pawn-grabbing variation (interestingly, a variation that he used against Kramnik in their world championship match in 2006), but out of a very complicated position, Anand found a nice sacrifice (23 Nxh6+) that invaded Topalov's insufficiently protected King (Black had only one Rook in the King side, while a Queen, Rook, two Knights, and a Bishop were all in the Queen side!) and quickly forced a win. Wow, what a game! Who said the Catalan is a boring opening leading to boring games?

It must be painful being Topalov right now. His attempts at creating unbalanced complications out of a Catalan as Black by playing Pawn-grabbing variations have so far not succeeded in his favor. We shall see how he tries to stop Anand's momentum in the upcoming rounds.
