Today's game wasn't terribly impressive, to put it mildly, but apparently both players got what they were looking for. Magnus Carlsen varied from his previous games with White and played 1.e4, and Viswanathan Anand played...the Berlin Defense. Had Carlsen headed for the ending it might have been interesting, and even 4.d3 can give Black some chances for a full game - if that's what Anand was after - but 4.0-0 Nxe4 5.Re1 is a super-safe approach. Black needs to exercise a little caution, and if he does that the result is a very level position. Anand did his job, while Carlsen played immediately throughout, swapped all the pieces, and in a dead drawn pawn ending 33 moves in the players called it a day. (The game can be replayed here, with my light notes.)
So Anand appears to be putting all his eggs in one basket, and will give it a go with White in round 9 on Thursday, after the rest day.
