Pawn Storms: Ivanchuk - Radjabov

Wijk aan Zee: Corus Chess 2009, Round 3

Vassily Ivanchuk is storming Teymour Radjabov's King's Indian Defense with every available pawn.

Corus Chess (3), Wijk aan Zee 2009

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 O-O 6.Nf3 e5 7.O-O Nc6 8.d5 Ne7 9.b4

Black to move

This position is common enough to lead chapter four in Joe Gallagher, Starting Out: The King's Indian (2002), where he writes:
Over the last six or seven years the Bayonet Attack has been one of White's main success stories in the King's Indian.
Gallagher, Starting Out: KID, 61
I'm not certain that in the six years since Gallagher made that statement it has continued as White's most successful line, but we see that the top rated competitor at Wijk aan Zee thinks it is good enough. It appears as the most popular move in my database of master level games since 2003.

9...Ne8 10.a4 f5 11.a5 Nf6 12.Bg5

Black to move

This move appears to be the novelty. 12.Nd2, a6, and exf5 appear in the ChessBase online database. 12.Nd2 was played in the only high level game among these four: Miroshnichenko-Nataf, Kapuskasing 2004. White won.

12...Nh5 13.exf5 gxf5 14.Qd2 Nf6 15.c5 Bd7 16.b5

Black to move

16...Be8 17.c6 b6 18.Nh4 Bf7 19.Bd3 Bg6 20.f3 Qe8 21.Kh1 Kh8 22.Bc2

I started following three other games, but this one has absorbed my interest (and my weak typing skills creates certain limitations for multi-tasking). Two of the other games were drawn, and Kamsky defeated Morozevich.

Back to Ivanchuk - Radjabov


White to move

23.g4 Nfg8 24.Ra4

In the other games in the Corus A group, the two Dutchmen, Van Wely - Smeets, drew in thirty moves. Adams - Dominguez, and Karjakin - Wang Yue are still in progress. My kibitzer, Fritz 9, thinks Karjakin might be gaining a slight edge, but is more confident that Adams has winning chances. It also likes Ivanchuk's position in our main game.

24...Rae8 25.axb6 axb6 26.Ra7 Rc8 27.Nxg6+ Qxg6 28.Rg1

Black to move

It is 8:04am PST, and I really should get some breakfast. I also need to decide whether I'll blog to the end of the game, or go downtown and join the Martin Luther King, Jr. Day parade. My son is meeting a bunch of his school friends for the parade, and asked me yesterday if I was going, too.

28...Qf7 29.Rg3 e4 30.Ne2 Nf6 31.Nf4

8:21am PST. Breakfast is ready.

31...exf3 32.gxf3 Nfxd5 33.Rxf3 Nxf4 24.Qxf4 Bf6

White to move

35.Bb3 Qh5 36.Bxf6+ Rxf6 37.Be6

Black to move

37...Rcf8 38.Rxc7??

Ivanchuk's game from the early moves has been leading to this point, but 38.Rg3 must be played first. Time pressure provoked an error again, as it did in round 1. Bad day for Chucky.

Black to move

38... Rxe6 39.fxe6 Rxf4 40.Rxf4 Qd5+ 41.Kg1 Qg5+ 0-1

Time for me to go to a parade.


  1. Time for Ivanchuck to sit at his board and play during photo taking otherwise he will lose more games thanks to lack of time.

  2. I think I'm still fast asleep during the start of the round when the photographers do their business. Is Ivanchuk too busy posing, or is he away avoiding the commotion?

  3. He's away to avoid all the flashes and such. Doesn't like all those photography.

  4. The flashes would give me a headache. But, he could wear sunglasses if that is the issue.
