Anand -- Carlsen, Game 10

World Champion Magnus Carlsen leads challenger and former champion Viswanathan Anand 5-4 after nine games. The match is being played at the Olympic Media Center in Sochi, Russia. Yesterday's game 9 started with the variation of the Berlin Defense to the Spanish Opening that appeared in game 7. Game 7 was on the verge of setting the record for longest World Championship game ever played, but fell short by two moves.

With three games remaining, Anand is under pressure to produce a win. Both players have demonstrated exceptional opening preparation for this match. Both are confident.

Following these games live and blogging them while in progress is both enjoyable and exhausting. The games start at 3:00 pm in Sochi, which is 4:00 am my time. Because of the importance of game 10, I set my alarm for 4:00 am for the first time during this match. I also prepared the beginning of this post last night.


I predict the game's first moves: 1.d4 Nf6 2.c4.

Every time that Anand has had White, these have been the moves. Will they vary today?

1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Qb3 dxc4 6.Qxc4 0–0 7.e4 Na6 8.Be2 c5 9.d5 e6 10.0–0 exd5 11.exd5 Re8

These moves were played rapidly, and now Anand begins to think. Carlsen opted for a Grunfeld Defense, as in game 1 of this match. However, Anand varied from that game on move 4.

After Carlsen's 11...Re8

I have played the Grunfeld and have played against it. However, I have no experience  with 5.Qb3 and subsequent moves.

12.Bg5

Anand spent about ten minutes. 12.Rd1 is the most popular move, and was Anand's choice when he had the diagram position twenty years ago. 12.Be3 and 12.Bc4 have also been played by Grandmasters.

15.Nxe4

When the reference game was a long Black win, it dawns on me that Carlsen could be seeking to bring this match to a rapid conclusion. If he manages a win with Black, he needs only one draw in the last two games to secure his title.

15...Bxe4

Peter Svidler, who with Sopiko Guramishvili is providing live commentary for the official site, thinks that it is likely both players are still in their preparation.

16.Qc1

Anand spent fifteen minutes on this move.

Svidler, who plays the Grunfeld, thinks that Anand's advanced central pawn is strong. I find it reminiscent of a game Garry Kasparov played in his youth, which he comments upon in some depth in Kaparov on Kasparov, Part 1: 1973-1985 (2011).

16...Qf6

I expected 16...Kh7. Anand had been thinking for eight minutes as Svidler and Guramishvili return from a short break.

Svidler is confessing that he considered Carlsen's move, although he did not mention it earlier.

After Carlsen's 16...Qf6

17.Bxh6 Qxb2

A queen swap here followed by exchanges of bishops for knights to double the opponent's pawns seems to make the d-pawn less of a threat. Black should hold the position.

18.Qxb2 Bxb2

Although 19.Bxa6 is tempting, keeping the bishop pair on the board offers better prospects for applying the sort of pressure that could lead to a win.

In general, I like having the Black side of the Grunfeld with a two to one pawn majority on the queenside. However, in my experience, Black's c-pawn usually gets exchanged for White's d-pawn. Here, that d-pawn is a potential monster.

19.Ng5

Susan Polgar suggested this move in a tweet while Anand was contemplating 18.Qxb2.

Anand has 51 minutes remaining. As Carlsen is thinking, I notice that he is a player who tips his head from side to side while calculating potential exchanges. It is subtle, which helps to explain why I had not noticed it before.

Carlsen has been thinking for twenty minutes.

"The gloves are off," Fabiano Caruana tweeted.

After thirty minutes of thinking, Carlsen played.

19...Bd4

Problems with the delay, feed, or hackers caused Svidler to briefly perceive that 19...Bxg2 had been played.

20.Nxe4 Rxe4 21.Bf3 Re7 22.d6 Rd7 23.Bf4

I had these moves in my database before they were played.

After Anand's 23.Bf4

White's d-pawn is blockaded and Black's knight may now have time to find a more useful square, perhaps Na6-b4-c6. Would Anand snap it off on c6? Perhaps, Carlsen needs to slide the other rook to c8 first.

23...Nb4 24.Rd2

Surely White cannot let the a-pawn drop. Or, can he?

24...Re8

This move must be much stronger than my idea.

Svidler has introducing a guest, an expert on the Grunfeld, when the live commentary feed died. Perhaps the broadcast is working elsewhere in the world.

Refreshing my browser brought it back, so the problem seems to be local.

25.Rc1

Anand has 22 minutes to get to move 40.

25...Re6 26.h4

Anand avoids backrank checkmates and also prevents g6-g5.

The problems I was having listening to the commentary continue, so I am missing interesting Grandmaster analysis. These problems seem to stem from my notebook computer, which often has connectivity issues. It is a nice box, but the internal WiFi seems substandard. The video works fine on my iPad, but the battery needed charging so I switched to my notebook.

I suppose that I could move the charger to where I am sitting in the living room. These First World problems with technology are soo troubling.

26...Be5

The analysts are not optimistic concerning Anand's ability to play for a win in this position now.

After Carlsen's 26...Be5

27.Bxe5 Rxe5 28.Bxb7 Rxb7 29.d7 Nc6 30.d8Q+ Nxd8 31.Rxd8+

White looking at the position after 26...Be5, I entered some moves in my database. These moves were soon played on the board.

31...Kg7 32.Rd2 1/2-1/2

I did not get as far as the last move by each player in my guess-the-move.

The draw should be considered a victory for Carlsen in terms of the match situation. With two games remaining, Carlsen leads 5.5-4.5.

In the press conference, Anand mentioned 24.Re1 as an alternative to 24.Rd2. The commentators seemed to suggest that Anand lost control of the position near that point in the game.
