Anand,Viswanathan (2783) - Leko,Peter (2751) [D47]
Miskolc Rapid (3), 04.06.2009 [Meszaros/Berkes]

1.d4 d5. Of course, Peter didn't want to play again his favourite Grunfeld defence because of his lost second game. 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 5.e3. Peter has chosen the Anti-Meran System, which is Anand's prefered weapon but with Black! 5...Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 Bb7 9.a3 b4 10.Ne4 Nxe4 11.Bxe4 bxa3 12.0-0 Bd6 13.b3 Nf6 14.Nd2!? This is a well-known position where White sacrifices a pawn to sharpen the fight. 14...Nxe4 15.Nxe4 Bxh2+ 16.Kxh2 Qh4+ 17.Kg1 Qxe4 18.f3 Qg6. While the target of White are the black squares around the black king Leko starts immediatly counterattack against the g2 square. 19.Bxa3 h5!

20.Qd2N. A harmless novelty. Black has more dangerous threats, which is why Anand has to exchange the queens. [20.Bc5 h4 21.e4 Qg3 22.Qe1 Qxe1 23.Rfxe1 a6 24.f4 f6 25.Re3 1/2-1/2 Czarnota-Balogh, Baden Baden 2009] 20...Qg3 21.Bc5 [21.Qb4?! 0-0-0 22.Bb2 (22.Rf2 h4) 22...a6 23.Rfc1 h4 24.Rxa6 h3! 25.Raxc6+ Bxc6 26.Rxc6+ Kd7 27.Qb7+ Ke8-+] 21...h4 22.Qf2 Qxf2+ 23.Rxf2 a6 24.e4 f6 25.Ra4 Rd8! 26.f4 Kf7 27.Kh2! Rd7 Inaccuracy. Thought the position is very close to equal, Black could have more hopefully continuations, for example: [27...Rh5!? 28.Kh3 Bc8; 27...Rh6!?] 28.Ra3! with the idea b4, Rh3 28...Bc8 draw.

Leko,Peter (2751) - Anand,Viswanathan (2783) [D97]
Miskolc Rapid (4), 04.06.2009 [Meszaros/Berkes]

1.d4 Nf6 2.c4 g6 3.Nc3 d5 An intresting "provocation": Anand is not afraid to play Grunfeld with black! 4.Nf3 Bg7 5.Qb3 dxc4 6.Qxc4 0-0 7.e4 a6 8.Be2 b5 9.Qb3 c5 10.dxc5 Bb7 11.0-0 Nbd7 12.e5 Nd5 13.Nxd5 Nxc5 14.Nxe7+ Qxe7 15.Qa3

15...Rfe8N. Novelty: the rook gives his place for the queen but Leko finds the weak point of this plan. [15...Rac8 16.Bf4 Rfe8 17.Rac1 Bxf3 18.Bxf3 Bxe5 19.Be3 Bd6 20.Rcd1 Qf6 21.Rd5+/= Alterman-Pelletier, Bad Wiessee 1997] 16.Bg5 Qf8 17.Bd2! +/=. This unpleasent "comeback" of the dark squared bishop does not give other choice to Anand to play a worse endgame. 17...Bxe5 [17...Rac8 18.Bb4 Bxf3 19.Bxf3 Bxe5 20.Rac1 Qh6! 21.g3 Na4 22.Rxc8 Rxc8 23.Bb7 +/=] 18.Nxe5 Rxe5 19.Rfe1 Rae8 20.Bf1 Rxe1 21.Rxe1 Rxe1 22.Bxe1 Ne6 [22...Ne4 23.Bb4 Qb8 24.Qe3 +/-]

23.Qg3! Keeping the queen is the strongest plan. At same time in my opinion (IM Meszaros) changing the queens was a reasonable possibility. The pair of bishops means a serious advantage in positions like this (symmetrical pawn structure, the central pawns are absent) and Black cannot easily build a fortress on the queenside because of the too advenced a6-b5 pawns. We have to mention that the time pressure helped neither the attacking nor the defending side! Time-wasting calculations of variations or a sure and longtime advantage in the endgame? Peter chose the first option. 23...f6!? 24.Bc3 Qd8 25.h4 Kf7 26.Qe3 h5 27.a3 Qd5

28.Qb6? [28.Qh6 Bc6 (28...Qe4 29.Qh7+ Ng7 30.Bd2!+/-) 29.Qh8 Ng7 30.Qc8 Nf5 31.Bb4 +/-] 28...g5! Anand begins counterplay on the king-side, reason is changing the pawns. 29.hxg5 fxg5 30.f3 h4 31.Qe3 h3! 32.gxh3 Qxf3 33.Qxf3+ Bxf3 34.Kf2 Be4 35.Ke3 Bf5 36.Be5 Kg6 37.Bg2 [37.b4 +/=]

37...Nc5!=. After this move White cannot save his pawns from the change on the queenside. 38.Bd6 [38.b4 Nd3 39.Bg3 Nb2! 40.Kd4 Be6 41.Bb7 Nc4 42.Bxa6 Nxa3=] 38...Nd3 39.b3 Ne1 40.Bb7 Nc2+ 41.Kd2 a5 42.Bg2 b4 43.axb4 axb4 44.Bc5 Na1 45.Bd5 Bxh3 46.Bxb4 Bf5 47.Bc5 Nxb3+ 48.Bxb3 Be4 49.Ke3 Kf5 50.Ba4 Bh1 51.Bc2+ Ke6 52.Kf2 Kd7 53.Kg3 Kc6 54.Be3 Kb7 55.Kg4 Ka8

56.Kxg5 Bg2 draw.
