Dortmund Sparkassen Open

(1) Carlsen - Jakowenko [C67] 02.07.2009 [FM Valeri Lilov] 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 Nxe4 5.d4 Nd6 The beginning of the Berlin defence, which is a very popular weapon in the hands of the modern grandmasters. 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8 9.Nc3 Ke8 10.h3 h5 The main continuation is 10...a5, but this move also deserves some attention since if White goes with g4-hxg4-hxg4, black's rook will get opened. 11.Ne2 An interesting idea by White that has been used several times before. White is getting the knight to the f4 square from where it can support the play on the central files. 11...Be7 12.Bg5 Be6 13.Nf4 Bd5 14.Bxe7 Kxe7 15.Ng5 Nd4 16.Rad1 Ne6 17.Ngxe6 Bxe6 On a first sight, it looks like the position is equal. However, considering black's inactive bishop on e6, we can admit that white has better chances. #0/0 18.h4 a5 19.a3 a4 20.Rfe1 g6 21.f3 Ra5 22.c3 Rb5 23.Re2 Ra8 24.Rd4 Raa5!? 25.Kf2 Rxe5 The following exchange forces the game into a drawish ending but nevertheless, black has to solve problems. 26.Rxe5 Rxe5 27.Rxa4 Rb5 The simple 27...b5 would of guarantee to black an easy draw. 28.b4 It was interesting to play 28.Rb4. The idea is when/if Black exchanges to re-take with the c-pawn and leave the c and a-pawns for the ending. 28...c5 29.Ra7 cxb4 30.cxb4 # 30...Kd7? The beginning of a wrong plan. Black had to neutralize White's knight with 30... Bc4 and then with a move like Kd6 prepare c7-c5. Once c5 is played, Black's rook will get out and the draw is simple. 31.Ne2 Now, white's is being very flexible and makes a lot of problems to black's passive rook and inactive bishop. 31...Rb6 32.Ke3 Bc4 33.Nd4 Kd6 34.Ra5! The rook gets to the fifth rank and is going to exploit Black's advanced h5 pawn to his advantage. An opportunity of g2-g4 looks pretty opened now and White is going to get a passed pawn on the kingside. 34...Ra6 35.Rxa6+ bxa6 36.g4 hxg4 Allowing White to make a passed pawn was not the best decision for Black. It was much better to continue with Ke5 and try to hold the fifth line. 37.fxg4 Ke5 38.Nc6+ Now it's all clear. White's king comes forward and white's knight dominates the bishop. 38...Kf6 39.Kf4 Ke6 40.h5 gxh5 41.gxh5 Bd3 42.Ke3 Bf1 43.h6 Kf6 44.Ne5 Bb5 45.Kd4+- Ba4 46.h7 Kg7 47.Nxf7 Kxh7 48.Ng5+ Kg6 49.Ne6 1-0

(2) Leko - Kramnik [E04] 02.07.2009 [FM Valeri Lilov] 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.g3 dxc4 5.Bg2 Bb4+ 6.Bd2 a5 7.Qc2 Bxd2+ 8.Qxd2 An interesting and pretty much new idea for white. He wants to keep his queen on the diagonal, making b7-b5 a bit more problematic. However, the time lost can be used by black to get equality. 8...c6 9.a4 b5 10.axb5 cxb5 11.Qg5 0-0 12.Qxb5 Ba6 13.Qa4 Qb6 14.Nbd2 # Black is having a bad pawn structure at the moment, but the active pieces which he gets are totally compensating his weaknesses. 14...Bb5 15.Qa3 Nc6 16.0-0 Rab8 17.Rfc1 Forcing equality. It was more ambitious to play 17.Rfd1. 17...Nxd4 18.Nxd4 Qxd4 19.Nf3 Qb6 20.Qxa5 Qxa5 21.Rxa5 Bc6 22.Rxc4 Bxf3 23.Bxf3 Rxb2 24.h4 1/2-1/2

(3) Naiditsch - Bacrot [C89] 02.07.2009 [FM Valeri Lilov] 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d5 Black chooses to play the Marsall attack which is very active and interesting attacking system for Black. 9.exd5 Nxd5 10.Nxe5 Nxe5 11.Rxe5 c6 12.d3!? Bd6 13.Re1 Bf5 14.Qf3 Qh4 15.g3 Qh3 16.Bxd5 cxd5 17.Qxd5 Rad8 The exchange gave Black some advantage in development and more pieces attacking. However, fortunately for White, Black needs to play only the most precise moves. Otherwise he can lose his compensation. 18.Qg2 Qxg2+? The queen had to retreat - 18...Qh5, after which black was keeping the opportunities to attack against white's king. It is obvious now that in the endgame, the pair of bishops won't be sufficient compensation for the extra pawn of White. 19.Kxg2 Bxd3 20.Be3 Be4+ 21.f3+/- Bc6 22.Nd2 Rfe8 23.Nb3 f6 24.Nd4 Bb7 # 25.g4?! It was much better to continue with 25.Nf5! Bf8 26.Bd4 keeping good activity and neutralizing Black's bishops. 25...Bc5 26.b4? That move misses the advantage. Now, the backward's pawn at c3 cannot be repaired. White can never get a passed pawn. 26...Bxd4 27.Bxd4 Rxe1 28.Rxe1 Kf7 29.Bc5 Rd7= 30.h4 Bd5 31.a3 Be6 32.Bd4 Bc4 33.Kg3 Re7 34.Rd1 Bb3 35.Rd2 Re1 36.h5 Rd1 37.Re2 Rd3 38.Kf4 Bd5 39.Re3 Rxe3 40.Kxe3 1/2-1/2
