Kibitzer's Corner
Nov-07-04  patzer2: Zsuzsa Polgar demonstrates that the Taimaov variation of the sicilian still has sting left in it for Black. Her play after 30...f6! is very impressive.
Nov-07-04  patzer2: 47...Bb3! makes for a great Rook, Bishop and pawn endgame study. Despite a two year rest from rated games, Susan Polgar's game looks as sharp as ever. I wonder if she is working with her sister Judit to sharpen her skills?
Feb-14-05  Albertan: Hi Patzer, the Taimanov is a great opening for Black it is flexible:it can be dynamic and also very solid,depending upon which lines you play. Susan Polgar is as strong as ever.I hope that she can find more time to play in tournaments so that we can enjoy her games.
Feb-14-05  Albertan: Here is some analysis I have done of this game.

anchez Castillo,S (2141) - Polgar,Z (2567)
36th Olympiad w Calvia ESP (1), 15.10.2004
Opening:Sicilian Defense,Scheveningen classical variation. ECO:B85

1.e4 c5

'Polgar returns to competitive chess, by playing the opening her sister also loves, the Sicilian Defense.Zsusa, unlike Judit, has used the moves 1...c5 and 1...e5 almost the same percentage...against an opponent who starts a game by playing 1.e4.

2.Nf3 e6


She decides to develop a second minor piece,rather than continuing with an open game via the move 3.d4.'


Beginning to develop her minor pieces and fighting for control of the d4-square.'

'Sanchez-Castillo returns to main opening theory.'


5.Nxd4 Qc7

'Influencing the e5-square and overprotecting her knight.'


'According to my database, this is the most popular continuation for White in this position.'


'Preventing her opponent from playing a knight into b5 (or her bishop), and beginning some queenside counterplay.'

Feb-14-05  Albertan: 7.0-0 Nf6

'The most often played idea by black in this position.'


'Taking her king off the a7-c5 diagonal (as she intends to play the move f2-f4 on move 9).White plays this move to avoid problems relating to the move...Bc5 after White has advanced the f-pawn to f4..' [ The main line of this variation continues: 8.Be3 Bb4 9.Na4 Be7 10.Nxc6 bxc6 11.Nb6 Rb8 12.Nxc8 Qxc8 13.e5 Nd5]


'Polgar develops another minor piece and prepares to castle on the kingside.' [ It is more popular for Black to capture on d4 on move eight ie. 8...Nxd4 9.Qxd4 Bc5 10.Qd3 b5 11.f4 Bb7 12.Bf3 h5 13.e5 Ng4 14.Bxb7 Qxb7 15.Ne4 Be7]


'Sanchez Castillo plays aggressively. this is the most popular move in this position, gaining space on the kingside.'


'A move almost universally played by Black in this position. Polgar creates a "little center" the Black e- and d-pawns occupy and influence key central squares. Black waits until an optimum moment to play the pawn break ...d5.'

10.Bf3 '

She spends a tempo to overprotect her d-pawn, this bishop move prevents the move 10...d5.' [ In my database two moves are more popular than the move Sanchez Castillo played, these being: (a) 10.Be3 ; and (b) 10.a4 ]


'The most popular idea for Black to play on move ten.' [ Rarely played in this position are two other moves: (a) 10...Bd7 and (b); 10...Nxd4]


'Sanchez Castillo uses a rarely played idea for her next move.She reduces the tension in the center. By doing so however, she also gains the opportunity to use her half-open d-file to pressure Polgar's weak d-pawn.'


'Polgar spends a tempo to centralize her rook before she develops her bishop. She intends to play the move ...e5 and develop her bishop on e6. 'Polgar spends a tempo to centralize her rook before she develops her bishop. She intends to play the move ...e5 and develop her bishop on e6. We can now identify the opening variation being used...Polgar is playing the Scheveningen variation of the Sicilian Defense (made popular by Kasparov in one of his World Championship matches against Karpov). Polgar has a flexible position. She intends to be patient and see what plan her opponent has before she develops her bishop and redeploys her pieces). This move of ...Rd8 tranposes the position to another variation of the Scheveningen . According to my database.Black has played the moves 11...b5. 11..Rb8. 11...Bd7 in this position. [ Usually in this position, Black plays another move either : (a) 11...b5 ; or (b) 11...Nd7 ]

Feb-14-05  Albertan: Patzer 2 it is interesting that my chessbase programs defined this variation as the Scheveningen variation and not the Taimanov.
Feb-14-05  Albertan: 12.Qe1N

Sanchez-Castillo takes her queen off the same file as Polgar's rook. Now the White queen can be transferred to the kingside using the ....d1-h4 diagonal. [ According to my database, prior to this game, White has always played the move 12.a4 in this position ie. 12.a4 b6 13.Qe2 Bb7 14.Be3 Rab8 15.Rad1 Nb4]


Polgar takes her rook off the same diagonal as her opponent's bishop and prepares to advance her b-pawn. [ Analysis:Hiarcs 8: 12...d5 13.e5 Nd7 14.Bd2 Nb6 15.Rb1 Nc4 16.Qf2 Bd7]


Spending a tempo to prevent Polgar from playing ...b5. [ Analysis:Hiarcs 8: 13.Be3 b5 14.Rd1 b4 15.Ne2 e5 16.Qg3 Be6 17.f5 Bc4 18.Rfe1 a5=]


Polgar intends to play the pawn break ...d5. So she advances her b-pawn to b6 so that she continues to cover the c5 square. [ Analysis:Hiarcs 8: 13...d5 14.e5 Nd7 15.Be3 Nb6 16.Bxb6 Qxb6 17.Qg3 f6 18.Bh5 Bd7 19.Bg4 fxe5 20.fxe5 Qc7 21.Qh3 Qxe5 22.Rfe1 Qd6 23.Bxe6+ Bxe6 24.Rxe6 Qf4 =]

Play in the game continued:


The move Hiarcs suggested in "its" analysis, Sanchez Castillo forces Polgar to use a piece to defend the Black b-pawn.


Polgar takes advantage of the fact that her opponent has advanced her a-pawn in order to launch her own atttack against the undefended White c-pawn (winning a tempo.) [ Analysis:Hiarcs 8: 14...d5 15.e5 Nd7 16.Qf2 Bb7 17.Rad1 Rbc8 18.Bh5 Bb4 19.Na2 Be7 =]


The lost tempo.


Occupying a key central square and creating a pawn lever..This pawn advance prevents the White knight from returning to d4 in the future. This comes at the cost of giving up influence over the key d5-square. [ Hiarcs 8 gave a better evaluation to the move ...d5 ie. 15...d5 16.a5 bxa5 17.e5 Nd7 18.Nxa5 Nc5 19.Bd4 Bd7 =]

Sanchez Castillo next played the move:


Preventing Polgar from playing her knight or bishop to b5. In addition Sanchez Castillo gives some luft to her king. [ Analysis:Hiarcs 8 16.a5 bxa5 17.Nxa5 Rd7 18.g3 exf4 19.gxf4 d5 20.e5 Ne4]


Polgar gains more influence over the d5-square...intending to play ...d5. Now her two rooks are also connected. [ Analysis:Hiarcs 8: 16...Be6 17.a5 bxa5 18.Nxa5 d5 19.Ba7 dxe4 20.Bxb8 Rxb8 21.Nxe4 Nxc2]


Centralizing her rook which results in more pressure against Polgar's backward d-pawn.

Feb-14-05  Albertan: 17...Bc4

Attacking the White rook winning a tempo. [ Analysis:Hiarcs 8: 17...Nd7 18.fxe5 dxe5 19.Bg4 Bc4 20.Be2 f6 21.Bxc4+ Qxc4 =]


The lost tempo. [ Analysis:Hiarcs 8: 18.Be2 Be6 19.Bf3 Rdc8 20.f5 Bc4 21.Rfe1 Re8 22.g3 Red8 =]


When the player of the Black pieces in the Sicilian can play this move at the appropriate time, she or he is viewed as having equalized the position. In fact Hiarcs 8 evaluates this position as completely equal =.0.05.


Sanchez Castillo opens up the f-file and forces Polgar to recapture on e5 with her queen.



Winning a tempo. [ Hiarcs gave a better evaluation to the move 20.Nd2: 20.Nd2 Bd6 21.g4 Rdc8 22.Bd4 Qf4 23.Nxc4 Rxc4 24.Be3 Qe5 25.exd5 Nxc2 26.Bc1 Nd4 =]


Creating the dangerous threat of 21...dxe4. [ Analysis:Hiarcs 8: 20...Qc7 21.Nd2 dxe4 22.Ncxe4 Nxe4 23.Bxe4 Be6 =]


Sanchez Castillo ends the threat, and closes the center. This comes at the cost of allowing Polgar's knight to gain an outpost on the e4-square in the future. [ Analysis:Hiarcs 8: 21.Rge1 dxe4 22.Nxe4 Nfd5 23.Nbd2 Ba2 24.Nf1 Bh4 25.Neg3 Qc7 26.Be4 g6 ]


Attacking her opponent's queen. [ Analysis:Hiarcs 8: 21...Nd7 22.Nc1 Nxe5 23.b3 Bd6 24.N1e2 Bxe2 25.Nxe2 Qf5 26.Bxd5 Qxf2 27.Bxf2 Nxc2 And White lacks sufficient compensation for the pawn.]

Returning to the moves played in the game, Sanchez Castillo next played the move:


Allowing for the exchange of queens at the cost of giving Polgar the two bishops.


23.Bxf2 dxe4

Hiarcs 8 evaluates this position as .

Feb-14-05  Albertan: Next Sanchez Castillo moved her knight:


Centralizing her knight and creating the future threat of Nc6 if Polgar moves her knight from b4.
[ Analysis:Hiarcs 8: 24.Rxd8+ Bxd8 25.Nd4 Bc7 26.Re1 Bxe5 27.Rxe4 Bxd4 28.Rxd4 Rc8 =]

Attacking Polgar's unprotected bishop winning a tempo. [ Analysis:Hiarcs 8: 25.Nxd5 Rxd5 26.Nc6 Rxd1 27.Nxe7+ Kf8 28.Rxd1 Kxe7 29.Rd4 Nxc2 30.Rc4 Na1 31.Rxe4 b5 =]

[ Analysis:Shredder 6: 26...Bc6 27.Ncxe4 Nxc2 28.b3 Be7 29.Rgf1 Bd7 30.Rd2 Nb4]

The game now continued with the two players playing these moves:

Winning a tempo. Now Sanchez Castillo has to decide which knight she is going to keep on the board.


Retaining her knight. [ Playing a moves like 37.Ne2 or 37.Na2s is not desirable as it will result in an advantage to Polgar: (a) 37.Ne2?! Rxf8 38.Ng3 Bc6 39.Kh2 Re8 40.Nf5 Kh7 41.Bc5 Re6 42.Ne3 b3 ; (b) 37.Na2 Rxf8 38.Rd2 Rc8 39.Re2 Bd5 40.Nc3 Bb3 41.Nb5 Rd8 ]

[ Analysis:Shredder 6: 53.h4 Kh7 54.g3 Ra2 55.h5 Ra7 56.Bd2 Rd7 57.Bc3 Rd3 58.Be1 Rd5 59.g4 Rd7 ]

Polgar now queened her pawn which
resulted in the gaining of the exchange after:

71.Bxe1 Bxf3

Feb-14-05  Albertan: 2.gxf3

Leaving Polgar up the exchange.
However now Polgar also errs by playing the move:


[ Analysis: Better was 72...Kg6 73.Bb4 Rd5 74.Ke2 Kf5 75.Ke3 Rd1 76.Kf2 h4 77.Kg2 Rd4 78.Ba5 Rc4 79.Kf2 Rc2+ 80.Ke3 Rh2 81.Bc7 Rxh3 82.Kf2 Rh1 83.Kg2 Rc1 84.Bd6 Rc6 85.Bb8 Rc2+ 86.Kg1 h3 87.Bd6 Rg2+ 88.Kh1 Rf2 89.Bc5 Rxf3 90.Kh2 g4 91.Bd6 Rf2+ 92.Kh1 Ke4 93.Bg3 Rg2 94.Be5 g3 ( 94...Kxe5??

Returning to the moves played in the game, both
players now exchanged pawns:

73.hxg4 hxg4

and then Sanchez Castillo made
another mistake when she played the move:


According to endgame tablebases this move leads to a forced checkmate in 27 for Polgar! [ Sanchez Castillo could have drawn by playing the move 74.Kg3: 74.Kg3 gxf3 75.Bf2 Ke6 76.Bd4 Kd5 77.Be3 Ke4 78.Kf2 Rf8 79.Bc5 Rf7 80.Be3 Rf5 =]

The moves of the game end here.Either Sanchez Castillo resigned or lost on time. The game could have concluded with checkmate in this fashion.
