So, Anand bounced back in game 2, and the way he did so should be worrisome to Topalov. Anand avoided Topalov's home preparation and then outplayed him from what was probably a sligtly inferior position. The move to pay attention to is 15.Qa3. At bottom, it's just two games and too early for a lot of generalization.
On another note, do you find Topalov's unilateral decision to invoke the Sofia Rule in this match annoying? I confess that I do. The Sofia Rule requires draw offers to go through the arbiter, with granting based only upon repetition, perpetual, or theoretically drawn positions. I like the fighting spirit, but there are other ways to accomplish the end rather than by imposing a condition without agreement. The gesture strikes me as clumsy. It will be interesting to see how his decision plays out. I doubt that Anand will be intimidated. In fact, it might be more intimidating to have one's draw offers declined at the board.
