Anand,Viswanathan (2772) - Carlsen,Magnus (2861) [C42]
Tata Steel Wijk aan Zee, 17.01.2013
1.e4 e5 2.Nf3 Nf6
Sorting the database by the rating of the Black player reveals that Vladimir Kramnik is the highest rated player who has played the Russian Defense, or Petroff. That changed today. It may be a very long time before another player rated higher that 2861 plays 2...Nf6.
3.Nxe5 d6 4.Nf3 Nxe4 5.d4 Be7 6.Bd3 Nf6 7.0–0 0–0 8.h3 Re8 9.Nc3 Nbd7
They have deviated from the main line, but in the Russian Defense, the so-called main line has been subject to revision quite a bit lately. Of the nearly three dozen games that have reached this position, only two were played before 2000.

10...Nf8 11.d5 c6N
Possibly the game's novelty. A prior game was won in 100 moves by White after 11...N6d7 12.Ne4 Ng6 13.Nd4 Nf6 1–0 Horvath,A (2473) -- Kovacs,G (2498) Hungary 2012
12.Bf4 Bd7
The players transposed in a game between lesser masters that continued 12...cxd5 and Black won in 39 moves 0–1 De Dovitiis,A (2347) -- Gibson,T (2252) Villa Martelli 2008

So, we have an isolated queen pawn.
17.Qd3 Qb6
Update 5:42 am PST
18.Nxd5 Bxd5 19.Bxd5 Nxd5 20.Qxd5
The isolated queen pawn is gone, but does Anand get two isolated pawns on the queenside?
Black to move
Update 5:57 am PST
White's b-pawn looks safe, at least for the moment.
Update 6:15 am PST
20...Qxb2
Carlsen disagrees with my assessment.
21.Rab1
Anand considered the position for five minutes and then played the move that we expected.
21...Qxc2 22.Rxb7 Red8
A few moves were played rapidly. Now the clocks seem backwards on the website again. Anand is about fifteen minutes ahead on time, but the live feed displays the reverse.
Update 6:30 am PST
I have been awake since a bit before 5:00. I checked the games on my iPad before getting up. I rose from the warmth of the covers at 5:00, but did not start my coffee till after 6:00. Now, I am drinking that first sip as the player fire off rapid moves.
23.Qb3 Qxb3 24.axb3 1/2-1/2
I was planning to type something calling for predictions concerning who would offer the draw (as I'm fairly certain that I could hold either side against Rybka). But, I glanced over at my iPad and noticed that the players were analyzing the game.
Moving on Other Games
Update 6:40 am PST
There are other interesting games to watch. Houdini 2.0 that is running on the website thinks that Hou -- Nakamura is dead even, but the players do not know that.
Pentala Harikrishna is playing aggressively against Loek van Wely's Hedgehog.
Update 6:45 am PST
It appears that Aronian can win some material against Ivan Sokolov, but it is complicated. Sokolov gives up two queens in the sequence (because a pawn captures Aronian's queen and promotes) But White's bishop is en prise and retreating it gives Black a rook for a bishop.
Update 7:05 am PST
Sokolov gave up the bishop to keep his rook a stick two connected passed pawns into Aronian's face. We need to follow this game now. Time will be a factor. Twenty moves need to be played in a few minutes. Sokolov has less than fifteen minutes on the clock.
Sokolov,Ivan (2663) - Aronian,Levon (2802) [D91]

On to Hou -- Nakamura, where the American appears to have good winning chances.

Houdini 2.0 considered this position dead even. Stockfish is less certain. Note to self: get Houdini 3.0.

Is Nakamura letting another win slip from his grasp? Are computers wrong?
37.Re2 Rh4 38.Nb6 Rd8 39.Rc2
It is 7:47 am PST, which makes it 16:47 in the Netherlands. Play has been going for more than three hours.
39...b3 40.Rc3
Yifan makes the time control.
40...Rb4 41.Rc8 Rxc8 42.Nxc8 Kg7
I like Nakamura's position.

Time to watch the en passant videos as the players leave the playing room.
