(Hmm, kind of a mobster-y title there - but at least the Sicilian wasn't then quartered.)
I think the likelihood that Viswanathan Anand reads my blog is extremely close to zero, and the odds that someone on his team reads it is only infinitesimally greater. But it's still a happy coincidence that he acted in accordance with my advice to scrap the whole Berlin business and try a Sicilian with 2...e6. Magnus Carlsen, as chess fans everywhere surely expected, went for a sideline - in this case 3.g3. Soon Black had an isolated d-pawn, which is, I think, a nice structure for this match, as both players get what they want. The side facing the isolani can hope to positionally massage the opponent until the pawn eventually drops - just the sort of thing Carlsen likes to do (though not the only thing he is adept at, obviously) - while the side with the isolani gets to play actively and to fight for the initiative - the kind of chess Anand thrives on.
As far as I can recall, this is their first IQP (isolated queen's pawn - the d-pawn) game against each other, at least in a world championship, and it wound up drawn. First Anand was a tiny bit better, and then Carlsen had a slight edge, but ultimately neither player experienced any serious problems before they split the point after 47 moves. Thus this match, like their previous one, was tied 2-2 heading into the second rest day.
After the game Anand was basically satisfied with his play, except for a late oversight in his calculations that he was able to correct beforehand, while Carlsen seemed fairly disgusted by his own play. Does this mean that Carlsen will head for this line again, thinking he should do better next time? My advice to Anand & co. is that they repeat this. The opening was fine, and a return trip will let them work out the details even more effectively. As White objectively achieved nothing from the variation, and didn't saddle Anand with the kind of position where he must morosely and passively defend forever, there's no obvious reason why he shouldn't go for a second dose of this. And if Carlsen goes for an Open Sicilian, that's definitely playing to Anand's strength. So my prediction is that Carlsen will switch first moves next time, maybe going for the vague world of 1.Nf3.
