  Willem Wallekers: 36. Bc7 was winning.
From http://teletekst.nos.nl/all/876.html
Jan-21-05  acirce: How? Doesn't that just lead after 36..b3 37.Nc3 Bxd6 38.Bxd6 Ra1+ 39.Kf2 b2 40.Kf3 b1=Q 41.Nxb1 Rxb1 to an ending that should be drawn even without the b-pawn (as in the classical Capablanca vs Lasker, 1914)?

  Willem Wallekers: It wasn't my idea, I was obviously overconfident in teletekst's "expert". I tried 37. d7 and 37. Nd1 but that's more or less the same. Has it been proven that Capa played that endgame correctly?
Jan-22-05  percyblakeney: It does feel as if there ought to be a Grischuk win somewhere, maybe 25. Rxc7 would have been a good idea, there was time to take the d4 pawn a few moves later.
Jan-22-05  percyblakeney: 34. Nc4 could be a winning alternative, Fritz gives it +2.62, but both were in severe time trouble and I doubt that it's a clear win in any case.

Analysis of Grischuk-Polgar Wijk aan Zee round 6
I have also included notes from GM Valerij Popov (elo 2588) from this website: "http://www.ruschess.com/". A pgn file of this analysis has been posted in the group's file section (in the annotated games in pgn file).

Grischuk,A (2710) - Polgar,J (2728) Opening:Catalan Opening:Open variation ECO: [E05]
Corus A Wijk aan Zee NED (6), 21.01.2005

In this game Grischuk plays a system of play known as the "Catalan Opening." This opening combines the Queen's Gambit with elements of the English and Reti openings, in order to accentuate pressure on Black's Q4 (d5). It needs delicate handling by White, as a compromise must be made between the demands of development and the aims of positional play. Although an old opening, Tartakower played it in a 1929 Barcelona tournament and then named it after the region. Its adoption is a combined White/Black effort, often transposed in. (source:http://www.eudesign.com/chessops/ca...)

The game began with these moves:

1.d4 Nf6 2.c4

Grischuk indicates a willingness to play a Queen's Gambit.

2...e6

Judith infers that she is going to play a Nimzo-Indian Defense or a Queen's Indian Defense.

3.g3

Intending to fianchetto his king's bishop.

3...d5

This move is the main continuation in my database, she gains more of a presence in the center of the board.

4.Bg2

[ Analysis: In this position the move 4.Nf3 is more popular ie: 4...Be7 5.Bg2 0-0 6.0-0 dxc4 7.Qc2 a6 8.a4 Bd7 9.Qxc4 Bc6 10.Bg5 Bd5 11.Qd3 c5]

The game now continued:

4...Be7

Judit uses the most often played continuation for Black.

5.Nf3 0-0

The most popular move (for Black).

6.0-0

Grischuk also plays the most popular idea.

6...dxc4

By playing this move, Judith defines the variation being played:it is the Open variation of the Catalan. The main continuation in response to her move, he intends to recapture the pawn on c4 immediately.

  Albertan: 7.Qc2 a6

A move almost universally played in my database. She intends to play ...8...b5 to gain a tempo after Grischuk plays 8.Qxc4.

8.Qxc4

[ Analysis:In my database it is more popular for White to play the move 8.a4 ie. 8.a4 Bd7 9.Qxc4 Bc6 10.Bg5 Bd5 11.Qd3 c5 12.Nc3 Bc6 13.Rfd1 cxd4 14.Nxd4 Bxg2 15.Kxg2 Qa5]

8...b5

Gaining a tempo. This pawn advance is the only move Black plays in my database for this position (659 games).

9.Qc2

An idea almost always played by the first player in this position.

9...Bb7

She develops another piece, indicating she is going to fight for control of the h1-a8 diagonal. This is the only move Black plays in my database (654 games).

10.Bd2

The second most popular move in my database, developing another minor piece. [ Analysis:The main line in this position continues: 10.Bf4 Nc6 11.Rd1 Nb4 12.Qc1 Rc8 13.Nc3 Nbd5 14.Nxd5 Bxd5 15.Be3 c6]

Judit now played the move:

10...h6

Polgar creates luft for her king and also prevents Grischuk from playing Bg5. This move has been played in two games before this game.It seems that Grischuk was apparently willing to settle for a quick draw, as the move 10...Be4 leads to a draw by repetition of position ( ie. see the analysis relating to 10...Be4 below). [ Analysis:Usually in this position Black plays 10...Be4 ie. 10...Be4 11.Qc1 Bb7 12.Qc2 Be4 13.Qc1 Bb7 14.Qc2]

  Albertan: For his next move Grischuk played:

11.a3

Grischuk continues to follow known opening theory (preventing Polgar from playing ..b4).

11...Ra7

Again following known theory.Polgar spends a tempo to break any potential pin (against her rook) after Grischuk was to move his knight from f3.

12.Rc1N

Grischuk creates a double-attack against Polgar's c-pawn winning a tempo. This move appears to be a theoretical novelty. [ Analysis: The move 12.Bc3 was played in the following game: Johannessen,L (2538) - Holst,A (2358) [E05] Politiken Cup Copenhagen (8), 24.07.2004 1.Nf3 e6 2.c4 Nf6 3.g3 d5 4. d4 Be7 5.Bg2 0-0 6.0-0 dxc4 7.Qc2 a6 8.Qxc4 b5 9.Qc2 Bb7 10.Bd2 h6 11.a3 Ra7 12.Bc3 a5 13.Nbd2 a4 14.b4 axb3 15.Qxb3 Bd5 16.Qxb5 Rxa3 17.Rxa3 Bxa3 18.Ba5 Nc6 19.Qd3 Be7 20.Bc3 Nb8 21.Rc1 Bb7 22.Nb3 Bd5 23.Bd2 Ba3 24.Ra1 Bd6 25.Ne1 Bxg2 26.Nxg2 Nbd7 27.e4 Be7 28.Rc1 c5 29.dxc5 Nxc5 30.Nxc5 Bxc5 31.Qxd8 Rxd8 32.Rxc5 Rxd2 33.f3 g5 34.h3 Kg7 35.Ne3 Re2 36.Nf1 Nd7 37.Rb5 Kf6 38.Nh2 Kg6 39. Ng4 h5 40.Ne5+ Nxe5 41.Rxe5 Kf6 42.Ra5 Rb2 1/2-1/2]

14.Qe3

GM Valery Popov analyzing the game at the website:

  Albertan: The next move in the game was:

17...Re8

Centralizing her rook, placing it on the same file as his queen. She now threatens to play ...e5.

18.Qd3

Spending a tempo to take the queen off the same file as her rook.By playing the move 18. Qd3 Grischuk prevents Polgar from playing ...c5 and now he threatens to play e2-e4.(GM Valery Popov)

18...Qa8

Creating pressure against his knight.

19.Rac1

After this move GM Popov states: "It is time to admit that Grischuk has a stable positional advantage."

19...Rc8

Overprotecting her c-pawn.

20.b4

He spends a tempo to reduce the mobility of her dark-squared bishop.Judit's position is cramped and her pieces lack mobility and good squares to redeploy to in order to improve her position.
[ Analysis:Hiarcs 8: 20.Nh4 g5 21.Bxd5 Qxd5 22.Ng2 e5 23.Ne3 Qxd4 24.Qxd4 exd4 And White would have compensation for the pawn.]

For her twentieth move Judit played:

A waiting move, although now her rooks can connect themselves. [ Analysis:Hiarcs 8: 20...Ne4 21.Nh4 Nxd2 22.Qxd2 Qb7 23.Bxd5 Qxd5 24.f3 Qb7 ]

Grischuk's next move was:

21.Nh4

He offers to exchange bishops on g2 (which would end her pressure against his kingside caused by her battery of Queen and rook). [ Analysis:Hiarcs 8: 21.Ne1 Bxg2 22.Nxg2 e5 23.e4 exd4 24.f4 Ne8 25.Qxd4 Nf8 26.e5 Be7 ]

Polgar next played:

Grischuk's next move was:

He regains material equality. [ Analysis:Hiarcs 8: 25.e5 Nd5 26.Qxd4 N7b6 27.f5 Re8 28.Rc6 Raa8 29.Bxb6 cxb6 30.Qxd5 Rad8 31.Qa2 Bc5+ 32.R1xc5 bxc5 33.Rxc5 Qd7 34.e6 Qd4+ 35.Kh1 fxe6 ]

28.Rxc5

Grischuk goes up a piece.

The game continued with Grischuk playing:

29.Rd5?!

In his analysis GM Popov gave the ?! [ Analysis: According to GM Popov a better idea was 29.Qc3! (Hiarcs 8 a lso suggested this move) ie. 29.Qc3! Bxc5+ 30.Qxc5 Ra8 31.e5! "And White would have more chances to win than in he does in the game."-GM Popov.]

Play in the game now continued:

32.Ne4 b4?

GM Popov gives the ? in his analysis, stating "It is difficult to understand this move. The black bishop is out of play and also the pawn on b4 is not long for this world now." [ Analysis:GM Popov suggests that a better idea for Judith in this position was to play 32...f5!?: 32...f5 33.d6 Rf8 ( 33...Kh8 34.Nc5 Qc6 35.Ne6 Rg8 36.Bb4 Bxb4 37.Qxb4 Re8) 34.Nc5 Bxc5 35.Qxc5 Rf6 36.Bb4 Rf8]

  Albertan: Grischuk now played the move:

33.d6

Advancing his passed pawn, which frees up the d5-square for his knight.

33...Qb5
34.Qd5

Attacking her rook, winning a tempo unless she exchanges queens.

34...Ra7

[ Analysis:Worse is exchanging queens: 34...Qxd5?? 35.Nxd5 b3 36.d7 b2 37.Nec3 f5 38.d8Q+ Rxd8 39.Bxd8 ]

The game continued:

35.Qxb5 axb5

Polgar now played:

The lost tempo.

Grischuk's next move was:

( Threatening 39.Ndf6+! winning.)

38...b3

Advancing her passed pawn nearer to queendom seems the best idea.

  Albertan: 39.Bb4?

Grischuk makes a mistake. [ Analysis:GM Popov and Hiarcs 8: Best was >=39.Nef6+! gxf6 40.Nxf6+ Kg7 41.Nxd7 f6 42.Nxf6 Be3+ ( GM Popov gives the move 42...b2 here however the move 42...Be3+ is better). 42...b2 43.d7 b1Q 44.d8Q Be3+ 45.Kg2 And white would be winning, ) 43.Kg2 Bxc5 44.d7 Be7 45.Ne4 b2 46.Nd2 Kf6 =]

Returning to the moves played in the game:

39...b2

40.Nec3

Allowing him to play Nc1.

The game now continued:
