Anand-Kramnik: Game 6

World Championship matches are grueling affairs. The players and their seconds are in a contest that tests endurance as much as chess skill. Dedicated fans can also find the battle exhausting. I'm getting a late start this morning because I set my alarm for 6:00am--the time the game was scheduled to begin. Of course, it is late afternoon in Bonn because they are nine hours ahead of the west coast of the United States.

By the time I had my computer up and running, and my coffee poured, observers on Playchess were already discussing the novelty in game six: Anand's 9.h3.

I found seven other games that reached the position after 8...O-O. All of them continued 9.e3. Two seem worthy of mention: a blindfold game in which Anand had Black, and the most recent high level game.

6:47am PDT update

If the sort of game that comes out of this position is a long hard-fought draw, it bodes well for Kramnik. He needs wins even with Black if he can manage it. But Kramnik's specialty is extracting wins from positions that seem to offer nothing. Throw some minor pieces down and scatter some pawns on the board and sit down against Kramnik, it's his game.

9...b6 10.g4 Qa5 11.Rc1

On the other hand, Anand's 9.h3 and 10.g4 might portend another tactical melee, and so far he's been crushing Kramnik in such games.

11...Bb7

7:12am PDT update

I took a few moments to discuss engines, databases, and "the cynical age of chess" in the forums at ChessWorld. When I came back to the game, several moves had been played.

12.a3 Bxc3 13.Bxc3 Qd5 14.Qxd5 Nxd5 15.Bd2

Anand has the bishop pair, but we may be in for an endgame. I have not lost faith in Kramnik. The odds are against him, but he can come back.

15...Nf6



16.Rg1 Rac8 17.Bg2 Ne7

They have been playing a little more than an hour and a half.

7:58am PDT; 4:58pm in Bonn

On the Playchess server, Nigel Short offered a pithy comment:
It is all very clever. You leave your king in the centre, in preparation for the endgame, and connect your rooks via the third rank. 21st century chess!
18.Bb4 c5 19.dxc5

After two hours of play, each player has used approximately an hour.

Missing FoidosChess

I bought a ticket to watch game three through Foidos, but not the whole match. Had I bought one for today, however, I might have caught an interesting interview with one of the true gentlemen of the game, and one of the best players that ever pushed pawns--Anatoly Karpov. Dennis Monokrousses has a summary of some of the highlights of this interview at his The Chess Mind blog.

It appears that Kramnik has been studying this position for twenty minutes or so.



8:17am PDT update

A flurry of moves

19...Rfd8 20.Ne5 Bxg2 21.Rxg2

So much for Anand's pair of holy men. The clerics that play on white squares are gone. Now, it is bishop against knight with rooks still on the board. Two principles of endgame play seem significant.

1. Bishops work better with rooks, and are generally slightly better than knights when there are pawns on both wings.
2. Kramnik is the best endgame player alive.

8:45am PDT; 5:45pm in Bonn (time for some to think about dinner, while I fix my breakfast)

22...Ne4 23.Rxc8 Rxc8 24.Nd3 Nd5



Rolling Pawns has a nice chess blog and is following the game both here and at Crestbook, where Sergei Shipov is offering commentary.

25.Bd2

It appears that Kramnik lacks compensation for the pawn, but that doesn't mean he will lose this game. Earlier today, a discussion at Playchess reminded those of us that have forgotten that colors switch at the midpoint: Kramnik has Black today, and again in the next game. At least he hasn't lost with the Black pieces . . . yet.

25...Rc2 26.Bc1

That bishop on c1 anchors a nice pawn chain.

After Three Hours of Play

Kramnik's clock shows that he has about one-third of the time the players have left to get to move forty.

9:15am PDT

A lot of action while I was frying some eggs. I should have eaten hours ago, but I have this chess addiction.

The Playchess game clocks show Anand with twenty minutes and Kramnik with sixteen after

38.e5 Nd5 39.f6

Kramnik is in trouble

39...Kf7 looked to me like the best of some bad choices

40.Ne4 Nc4

Now that they've made the time control, a resignation is probably in order for Kramnik.

They've been playing almost four hours.

Kicking the Dead

As if it matters, Hiarcs 12 favors the obvious 41.Rxg7+ and White is more than +5.00

Anand, however, just played

41.fxg7

Hiarcs 12 now says +2.32 with 41...Rg8.

41...Kg8

If my chess engine can be believed, both players have made inaccurate moves. On the other hand, humans tire; computers less so.

10:10am PDT; 7:10pm in Bonn

Rumors on Playchess circulate that Kramnik has resigned.



The rumors prove false, as more moves were blitzed off moments ago.

42.Rd3 Ndb6 43.Bh6 Nxe5 44.Nf6+ Kf7 45.Rc3 Rxc3 46.g8Q+ Kxf6 47.Bg7+ 1-0

And now Kramnik gives up.

It is 10:22am PDT; 7:22pm in Bonn

Thank you Vishy for another terrific novelty. Vlad, my heart is with you and I remain hopeful even though reasons for optimism seem to be vanishing.

  1. How the computer estimate it after 17. Bg2 ?

  2. 0.16 after about a minute of analysis. Initially the engine preferred Ne4, but it quickly switched to Ne7, which Kramnik actually played.

  3. Thank you, so it's about equal for now.

  4. After twelve minutes of analysis, my Hiarcs 12 still favors the move Kramnik played and gives it 0.23, so White retains the advantage of first move and nothing more.

    I think that Kramnik has chances any time they reach an endgame.

  5. GM Shipov (on crestbook) says this is the time to do something for black, that's why Kramnik is thinking so long.

  6. I meant after 21. Rxg2, so he finally played 21. ...bxc5

    ReplyDelete
  7. After 41.fxg7 Shipov says Anand is too confident now to recalculate anything.

    ReplyDelete
  8. Dennis Monokrosses says that Anand has several ways to win, and this move tortures Kramnik a bit longer.

    Bad day for Kramnik and his fans (myself included), but Anand's play so far is this match is cause for excitement for the world of chess!

    ReplyDelete
  9. Yeah, Anand plays very well. I also support Kramnik, but even in soccer getting back after 0:3 is rare, and this is not soccer. I actually remembered Korchnoi getting 5:5 after 2:5 with Karpov, but ...

  10. There have been comebacks from -3 in World Chess Championship contests, but not in any of such a short duration as this one. Twelve games are too few for this level of match, and too few for Kramnik's chances.

    ReplyDelete
  11. Yeah, you need a long distance to do that. Kasparov "came back" from -5 in unlimited match with Karpov.
    I think 12 games format definitely affected today's game.
    Thanks for adding me to blogroll, I added you too.

  12. Half way thru and Anand leads with 3 points. This means that Anand only needs two more points (four draws) to take the match while Kramnik will have to take risk now to save the match.
