Ruan,Lufei - Koneru,Humpy [C45]
FIDE Women's Grand Prix Ankara, 22.09.2012
Game was extremely important ,as two leaders played.For Koneru the price of every game is extremely high,as she fights for the victory in the tournament ,which can bring her close to the World Championship once more. 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Bc5 5.Nb3 For different reasonsa this old line became more popular recently and happened in few games in Ankara.
5...Bb4+ This is IGM Oleg Romanishin old idea how to disturb simple and agressive plan of White with long castle. Old classical way is still played frequently 5...Bb6 6.Nc3 Nf6 7.Qe2 d6 8.Be3 0–0 9.0–0–0 Bxe3+ 10.Qxe3 a6 11.f3 b5 12.g4
12...b4 13.Ne2 Re8 14.g5 Nd7 15.Ng3 a5 16.Bb5 Bb7 17.Bxc6 Bxc6 18.Nd4 Bb7 19.Ndf5 g6 20.Nh6+ Kf8 21.f4 with serious attacking prospects,1–0 Muzychuk,A (2538)-Lahno,K (2536)/Rostov on Don 2011] 6.c3 [Main idea of the variation is to drive White Knights back 6.Bd2 a5 7.a3 Bxd2+ 8.N1xd2 a4] 6...Be7
7.c4 Idea of this move is to obtain structure ,similar to Maroczy Bind,fighting for space advantage. [Here White had few very serious options.the most logical seems to be 7.f4 d6 8.Bd3 Nf6 9.N1d2 0–0 10.Qc2 a5 11.0–0 Nd7 12.a4 g6 13.Nf3 Bf6 14.Be3 b6 15.Rad1 Qe7 16.Rfe1 Bg7 17.Bf2 Bb7 18.Bc4 Rae8 19.Qd3 Nc5 20.Nxc5 dxc5 21.e5 with white serious space advantage, Muzychuk,A-Ozturk,K/Ankara 2012 ; Not so logical here seems to be 7.g3 Nf6 8.Bg2 0–0 9.0–0 Re8 10.c4 a5 11.Nc3? (It is necessary to stop this Black pawn always,if it does not damage own position too much! 11.a4 ) 11...a4 12.Nd2 a3 13.b3 Bc5 14.Nb5 d6 15.h3 h5 16.Kh1 Bd7 17.f3 Qc8 18.Kh2 Ne5 with strong Blacks initiative, Kosintseva,T-Koneru,H/Ankara 2012 ] 7...Nf6 [Very serious line is to try to conduct f7-f5 attack of the White center 7...Bf6 8.Bd3 d6 9.0–0 Nge7 10.Nc3
10...Bxc3! 11.bxc3 0–0 12.Nd4 f5 13.f4 Nxd4 14.cxd4 fxe4 15.Bxe4 d5 16.cxd5 Nxd5 17.Ba3 Rf7 18.Qb3 Nf6 19.Bd3 Qxd4+ 20.Kh1 Be6 21.Bxh7+ Kxh7 22.Qxe6 Kg8 23.Rad1 Qa4 24.Qh3 1/2 Movsesian,S (2647)-Landa,K (2550)/Tripoli LBA 2004] 8.f3 [Simpler is to start with logical piece development 8.Nc3 0–0 9.Be2 Re8 10.f3 a5 11.a4? (Strange-even the top players allow this! 11.0–0 a4 12.Nd4 Bc5 13.Be3±) 11...d6 12.0–0 Nd7= 13.Be3 Bf6 14.Qd2 b6 15.Nd5 Nc5 16.Ra3 Bd7!„ 17.Nc1 Nb4! 18.Bd1 Nxd5 19.cxd5 c6! and Black starts to destroy opponents center, Ivanovic,B-Petrosian,T/Tallinn 1979] 8...0–0 [Possible is simple development 8...d6 9.Nc3 0–0 10.Be2 Ne8 11.0–0 f5 12.exf5 Bxf5 13.Nd5 Nf6 14.Nxe7+ Qxe7 15.Bg5 h6 16.Bh4 Ne5 17.Nd4 Bh7 18.Bf2 Rae8 and Black completes development with balanced position, Cioara,A-Godena,M/Nova Gorica, 2000 ] 9.Be2 [Better way to fight for some advantage was 9.Nc3 a5 10.a4! Despite weakening square b4,much more important fact is to stop opponents space agression 10...Bb4 11.Be2 d6 12.0–0 Ne5 13.Qc2 c6 14.Be3] 9...a5
10.0–0? No!As it was mentioned ,it is necessary to stop such pawns at any price [10.a4] 10...a4 11.Nd4 Bc5 12.Be3 Qe7 13.Nc3? [Correct was 13.Qd2 Nxd4 14.Bxd4 Qe5 15.Rd1 d6 16.Nc3 Be6 17.Rac1 Bxd4+ 18.Qxd4 Qxd4+ 19.Rxd4 Bd7 20.Kf2 with more comfortable end.Now Black obtain the possibility to create some weakness in Whites position.] 13...a3! 14.b3 [After 14.Rb1 axb2 15.Rxb2 b6 weaknesses a2 and c4 will become decisive factor in future fight.] 14...Qe5 15.Ncb5
15...d5!! This powerfull blow reverts the course of the game and destroys Whites center. 16.Qd2 [Chances for survival promised just Queens exchange 16.Kh1 dxe4 17.Nxc6 bxc6 18.Bxc5 Qxc5 19.Qd4 Qxd4 20.Nxd4 Bb7 21.Rfd1] 16...dxe4 [Black could chose more active continuation 16...Bb4 17.Qc1 dxe4 18.Nc2 Ba5 19.Kh1 Qe7 20.Ncxa3 Ne5 21.Nc2 exf3 22.Bxf3 c6 23.Qa3 Qxa3 24.Nbxa3 Nxf3 25.Rxf3 Bg4 with strong threats.] 17.Nxc6 [More chances to save the game would offer blockading plan 17.f4 Qe7 18.Nxc6 bxc6 19.Bxc5 Qxc5+ 20.Qd4 Qb4 21.Nc3 Bg4 22.Rad1 Bxe2 23.Nxe2 h6 24.Qe3 Rfe8 25.h3 Rad8 26.Nc3] 17...bxc6 18.Bxc5 Qxc5+ 19.Qd4 Qg5
Black obtained similar position as in annotation to 16 move,but with one tempo up. 20.Nc3? [Once more ,better was to try to block the position 20.f4 Qg6 21.Nxc7 Bh3 22.Rf2 Rad8 23.Qc5 Bg4 24.Re1 with some chances for survival.] 20...Bh3 21.Qf2
21...Bxg2! Tactics ,which involves double attack with deflection of the White Queen. 22.Qxg2 Qe3+ 23.Kh1 Qxc3 24.fxe4 Rad8 25.Bf3 [No chances for survival promised 25.Rad1 Rfe8 26.Bf3 Rxd1 27.Rxd1 g6 28.Qe2 c5] 25...Rd2 26.Qg3 Nd7 [Strong attack obtained Black after 26...Re8 27.Qxc7 Nd7 28.Qxc6 Qb2 29.Kg1 Qe5 30.Bg2 Re6 31.Qc8+ Nf8 but still it would not be so easy.] 27.Qxc7
[Dominating position of the Knight would decide game in Blacks favour after 27.Rad1 Rxd1 28.Rxd1 Ne5 29.Bg2 Qc2 30.Rf1 f6] 27...Qe5 [Very strong and logical seemed 27...Ne5 28.Bg2 Ng4 but Koneru decides to go into endgame ,which is more sofisiticated decision.] 28.Qxe5 Nxe5 29.Kg1 [Completely helpless was 29.Bg2 Rfd8 30.Rf5 f6 31.Kg1 Rb2 32.Rf2 Ng4] 29...Rfd8 30.Rf2 Rb2 31.Kf1 Nxf3 32.Rxf3 Rxh2 Very technical play of World Vice Champion! 0–1
