Budapest 2003 , 16.04.2003

B33: Sicilian: Pelikan and Sveshnikov Variations

1.e4 c5

The Sicilian Defense.

2.Nf3 Nc6

Contesting the d4-square.

3.d4 cxd4
4.Nxd4 Nf6
Developing another minor piece and winning a tempo. 5.Nc3 Almost always played here,the lost tempo.

5...e5

He immediately displaces her knight at the cost of giving her control of the d5-square. [ Much more popular in my database is to play ...d6 first ie. 5...d6 6.Bg5 e6 7.Qd2 a6 8.0-0-0 h6 9.Be3 Be7 10.f4 Nxd4 11.Bxd4 b5 12.Bd3 Bb7 13.Kb1 0-0]

Feb-13-05  Albertan: 6.Ndb5

Almost always played here.He entices her to play ..a6. The White knight threatens to head for d6 or he could also intend 7.Bg5.

6...d6

Almost always played in my database,he gives support to his e-pawn and opens up the diagonal to develop his queen's bishop.

7.Bg5

Again a move almost universally played here at this stage,developing another minor piece and pinning his knight.

7...a6

Almost universally played in this position in my database,he drives her knight back to a3.

8.Na3

[ Rarely played in my database is 8.Bxf6 ie. 8.Bxf6 gxf6 9.Na3 b5 10.Nd5 f5 11.Bd3 Be6 12.0-0 Bxd5 13.exd5 Ne7 14.c3 Bg7 15.Qh5 e4 16.Bc2 Qc8] Returning to the moves of the game which continued:

8...b5

Again a move almost always played in this position by Black threatening ...b4.

9.Bxf6

The most often played continuation,giving up the two bishops to Leko. [ The other main idea is to take advantage of the d5-square and occupy it via Nd5 ie. 9.Nd5 Be7 10.Bxf6 Bxf6 11.c3 0-0 12.Nc2 Bg5 13.a4 bxa4 14.Rxa4 a5 15.Bc4 Rb8 16.b3 Kh8 17.0-0 f5 ( 17...g6) ]

Returning to the moves played in the game, Leko next played:

9...gxf6

[ Rarely played is 9...Qxf6 ]

10.Nd5

Almost always played here,she occupies one of the most key squares in this opening,d5,which hampers his ability to coordinate his pieces.

10...f5

The most often played move,he attacks the pawn which is defending the knight. [ Also popular is the move 10....Bg7 ie. 10...Bg7 11.c3 f5 12.exf5 Bxf5 13.Nc2 0-0 14.Nce3 Be6 15.Bd3 f5 16.Qh5 e4 17.Bc2 Ne7 18.Rd1 Ng6 19.f4 ( 19.g4) ]

Feb-13-05  Albertan: 11.Bd3

The most popular continuation,she develops her last minor piece and overprotects her e-pawn in the process. [ The other popular idea here is to play 11.c3 ie. 11.c3 Bg7 12.exf5 Bxf5 13.Nc2 0-0 14.Nce3 Be6 15.Bd3 f5 16.Qh5 e4 17.Bc2 Ne7 18.Rd1 Ng6]

Play in the game continued:

11...Be6

Again a move almost universally played by Black in this position,he develops another minor piece and attacks her well-placed knight.

12.Qh5

She aggressively posts her queen,pinning his pawn on f7 in the process.Now she threatens to win a pawn and a tempo via 13.exf5. [ More popular in my database is to castle ie. 12.0-0 Bxd5 13.exd5 Ne7 14.c3 Bg7 15.Qh5 e4 16.Bc2 Qc8 17.Rae1 0-0 18.Kh1 Ng6 19.Bb1 Re8]

Leko's next move in the game was:

12...Rg8

He leaves his h-pawn enprise and attacks her g-pawn,offering to exchange a pair of pawns. [ More popular in my database is to fianchetto the king's bishop: ie. 12...Bg7 13.0-0 f4 14.c4 bxc4 15.Bxc4 0-0 16.Rac1 Rb8 17.b3 Qd7 18.Rfd1 Kh8 19.Qh4 Bxd5 20.Bxd5 ( 20.Rxd5) ]

Feb-13-05  Albertan: 13.g3

The most popular move,declining the exchange of pawns.

13...Rg5

Attacking her queen winning a tempo.
[ Slightly more popular in my database is the move 13...Rg4 ie. 13...Rg4 14.f4 exf4 15.Nxf4 Rxf4 16.gxf4 Qf6 ( 16...fxe4; 16...Qa5+) ]

The next move in the game was:

14.Qd1

The lost tempo.
[CC: 14.Qxh7 Bxd5 ( 14...Rc8 15.h4 Rg4 16.c3 Rg7 17.Qh5 fxe4 18.Bxe4 Bg4 19.Qh8 f5 20.Bg2 Kf7 21.Ne3 Qf6 22.Bd5+ Ke7 23.Bxc6 Qg6 24.h5 Qg5 25.h6 1-0 Jorge Bort,E-Linares Quero,A/Albacete 2001/EXT 2002 (25)) 15.exd5 Ne7 16.0-0-0 Qb6 17.Kb1 Qxf2 18.Rhf1 Qc5 19.c3 e4 20.Be2 Nxd5 21.Nc2 Rc8 22.g4 Nxc3+ 23.bxc3 Qxc3 24.Nd4 Bg7 25.Rxf5 Rxf5 26.Qxg7 Rf2 27.Qh7 Qb4+ 28.Ka1 Qc3+ Bauer,C-Komarov,D/France 1997/EXT 99/1/2-1/2 (29)]

Feb-13-05  Albertan: 14...Bxd5

He finally decides to eliminate her well posted knight. [ The only other move in my database is 14...Rg4 ie. 14...Rg4 15.f3 Rg8 16.Qd2 Rc8 17.c3 h5 18.Nc2 h4 19.a4 Na5 20.Qe2 Bh6 21.axb5 Kf8]

Polgar now played:

15.exd5

Winning a tempo unless he now plays ...Ne7.

15...Ne7

Threatening to win her d-pawn.

16.Nxb5!?N

This move may be a theoretical novelty.She offers to give up the exchange. [CC: 16.c3 e4 ( 16...Bg7 17.h4 Rg6 18.Nc2 e4 19.Be2 Qc7 20.a4 b4 21.h5 Rh6 22.cxb4 Qb7 23.b5 Bxb2 24.Rb1 Bc3+ 25.Kf1 a5 26.Ne3 Rf6 27.Rc1 Be5 28.Rc6 f4 29.gxf4 Rxf4 30.Nc4 Nf5 31.Rg1 Sideif Sade,F-Yurtaev,L/Dnepropetrovsk 1980/EXT 2002/1-0 (42)) 17.f4 Rg6 ( 17...Rg8 18.Be2 Qb6 19.Nc2 Bg7 20.Qd2 Bf6 21.a3 Kf8 22.Kf1 Kg7 23.Kg2 Rgc8 24.Rhg1 a5 25.Kh1 Rg8 26.Bh5 Qc5 27.Rad1 Kf8 28.Rg2 Rb8 29.h3 Ng6 30.Qe1 Qc8 31.Qg1 Bd8 32.Be2 Bezgodov,A-Tolstikh,N/Samara 2000/CBM 78/1-0 (80)) 18.Be2 Qb6 19.Qd2 b4 20.cxb4 e3 21.Qc2 Qxb4+ 22.Kf1 Bg7 23.Nc4 Rc8 24.Rd1 Kf8 25.Qd3 Rc5 26.Nxe3 Bxb2 27.Bf3 Rc3 28.Qe2 Qa3 29.Kf2 Bc1 30.Rxc1 Rxc1 Bezgodov,A-Smirnov,P/Samara 2000/CBM 78/1/2-1/2 (88)]

Feb-13-05  Albertan: 16...Qb6

Attacking her knight. [ Taking the knight would be a bad mistake as the following variation shows: 16...axb5?? 17.Bxb5+ Nc6 18.Bxc6+ Ke7 19.Bxa8 ]

17.Na3

She saves her knight. [ Fritz 7: 17.Qd2 e4 18.Qxg5 exd3 19.Nxd6+ Qxd6 20.cxd3 h6 21.Qh4 Bg7 And Fritz evaluates Black as having sufficient compensation for the two pawns.]

Feb-13-05  Albertan: 20.Rb1

Feb-13-05  Albertan: 22...Qf6

35...Nxe2

36.Kxe2

[ 36.Rxg5 a fruitless try to alter the course of the game 36...Rxg5 37.Kxe2 f4 ( ‹37...Qxd5 38.Qb3 f4 39.Qxd5 Rxd5 40.h6 ) ] The game continued:

[ 40...exf3?! is clearly inferior 41.Qxd6+ Kg7 42.Rhxf3]

Jul-30-05  Queens Gambit: I really like this game!!!!
Aug-04-05  Queens Gambit: I would like to hear opinions of this wonderfull and uncommon game.
Aug-05-05  SEMENELIN: Judit Polgar was not sure how to break the defense of Leko. She justs wastes pieces and breaking her own defense. observe her threats it is really meaningless and has no possible good outcome.
Sep-28-05  Caissanist: Albertan: thank you very much for your thorough and articulate annotations. I have always wondered why more games are not annotated in this move-by-move manner, you learn more and enjoy the game more when everything is explained.
Nov-24-12  Atking: Yes <Albertan> you did here a great work! Thanks. <SEMENELIN> I wonder if 21.f4 was not a key move of Judith great concept. 21...cxB simply 22.cxd R moves and 23.Qa4+ Just an idea to keep Judith story beautiful.

  plang: 16 Nxb5!? is an aggressive innovation that has not been repeated; later in the tournament Acs played the more restrained (and popular) 16 c3 against Leko and went on to win a nice game. Almasi thought that 19..Rd8!? was too passive recommending 19..e4 20 f4..Rg6 21 Be2..Rc8 instead. White went wrong with 21 Be2?..f4; instead 21 f4 was necessary when after 21..Rg6 (21..exd? 22 cxd..fxg? 23 Qa4+ wins) 22 Rb3..Qf6 23 Be2..Bg7 24 Kg2 and White has some advantage. Leko was critical of 30 h5?!(weakening g5) and 31 Be2?! but did not offer alternatives. After 34..f5! Black was winning. Also strong would have been 38..Bxh4 39 Rxh4..e3.

I often find games with the Sveshnikov difficult to understand. Leko and Almasi both analysed this game and had very views on where White went wrong.
