This was the last game to decide the winner in the Women section of the Blitz tournament in the 1st World Mind Sports Games. As the 2-games mini-match ended in a 1-1 draw, a final game would follow according to the tournament rules. White has got 6 minutes and Black 5 but the latter is getting the crown in a case of a draw.
1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Bc5 6.c3 b5 7.Bb3 d6 8.d4 Bb6 9.a4 Bg4 ( The main alternative is 9... Rb8 and now 10.Na3 as in Dominguez Perez,L-Shirov,A/Foros 2007 or (10.axb5 axb5 11.Qd3!? as in Adams,M-Shirov,A/Elista 2007.))
10.h3 (10.d5 doesn't seems to offer much: 10... Ne7 11.h3 Bh5 12.Re1 Ng6 unclear position Hamdouchi,H-Carlsen,M/Reykjavik 2006.)
10... Bh5 ( After 10... Bxf3 11.Qxf3 exd4 12.Bg5 White's compensation is excellent.)
11.Bg5 ( The main alternative is 11.axb5 but after 11... axb5 12.Rxa8 Qxa8 13.d5 Na5 (13... Ne7 14.Bc2 Bg6 15.Qe2 c6 16.dxc6 Qxc6 17.Re1 O-O 18.Na3 Rb8 19.Bd3 h6 20.Nd2 b4 21.cxb4 d5 22.Bb5 Qb7 23.exd5 Nexd5 24.Ndc4 Ne4 equal chances, quiet position Leko,P-Adams,M/Dortmund 1998) 14.Bc2 c6 15.dxc6 Qxc6 equal chances, quiet position Black should feel happy as in Majdan,J-Stefanova,A/Kusadasi 2006 and Anand,V-Naiditsch,A/ Dortmund 2007.)
11... Rb8 12.axb5 ( In their second match encounter, Kosteniuk chose 12.Qd3 Bxf3 13.Bd5 (13.Qxf3 exd4 14.axb5 axb5 15.Rd1 Ne5 unclear position) 13... Nxd4? (13... Bxe4 14.Bxe4 d5 15.dxe5 Nxe5 16.Qg3 Qd6 equal chances, quiet position) 14.cxd4 Bh5 15.Bc6+ Kf8 16.axb5 axb5 17.dxe5 dxe5 18.Qc2 h6 19.Bh4 g5 20.Bg3 Bd4 21.Nc3 White has a moderate advantage b4 22.Nb5 Kg7 23.Nxd4 Qxd4 24.Ra5 b3 25.Qc1 Qb4 26.Rxe5 Rhd8 27.Rc5 Rbc8 28.e5 Nd7 29.Rc4 Qb6 30.Re1 Nb8 31.e6 fxe6 32.Qc3+ Kf7 33.Qe5 Rd6 34.Qe4 Bg6 35.Qf3+ Ke7 36.Bxd6+ cxd6 37.Bd5 Rxc4 38.Rxe6+ Kd7 39.Bxc4 Qc5 40.Qb7+ 1-0 Kosteniuk,A-Stefanova,A/Beijing 2008.)
12... axb5 13.Qd3 ( In the final game of the their semi-final match Hou Yifan chose 13.Nbd2 exd4 14.Bd5 Ne5? (14... Ne7! 15.Bxf6 gxf6 16.cxd4 O-O 17.Qc2 c5 unclear position) 15.cxd4 Nxf3+ 16.Nxf3 Bxf3 17.Bc6+? (17.Qxf3 Bxd4 18.Bc6+ Kf8 19.Qd3 White has a moderate advantage) 17... Kf8? (17... Nd7!) 18.gxf3 White has a moderate advantage h6 19.Be3 Nh5 20.f4 g6 21.Qf3 b4 22.Kh1 Kg7 23.Rg1 Kh7 24.f5 Qf6 25.Bd5 Rhf8 26.Qg4?! (26.Bxf7 Rxf7 27.Rxg6 White has a decisive advantage) 26...

After this game I congratulated Antoaneta but I warned her not to repeat this variation for the time being. She didn't hear me and she lost both her games against Kosteniuk...) ( The other option is 13.Na3!? Bxf3 14.gxf3 exd4 15.Nxb5 h6 16.Bh4 g5 17.Bg3 dxc3 18.Nxc3 O-O 19.f4 Nd4 20.Bc4 White has a slight advantage Ivanchuk,V-Georgiev,K/Kusadasi 2006 but I am sure that Antoaneta has prepare something new.)
13... O-O? (13... Bxf3 seems to be a good move, transposing to the analysis given after White's 12th move 12.Qd3.)
14.Nbd2 White has a moderate advantage Now White has achieved an ideal position as she can protect her center and enjoy her space advantage.
14... h6?! (14... b4 15.Bd5 bxc3 16.bxc3 Ne7 17.Bc4 White has a moderate advantage looks like the only continuation.)
15.Bh4? (15.Bxf6! Qxf6 16.Qxb5 Na5 17.Bc2 White has a decisive advantage .)
15... g5 16.Bg3 exd4? ( Black's continues a series of mistakes. She should go for 16... Qd7! 17.d5 Ne7 18.Ra6 White has a slight advantage .)
17.cxd4 Bg6 18.Qc3?! (18.Rfe1 Nh5 19.Qc3 Ne7 20.Bh2 White has a moderate advantage was more accurate.)
18... Ne7 19.Rfe1 Ra8! White has a slight advantage 20.Rxa8 Qxa8 21.d5 (21.Bc2 d5! 22.exd5 (22.e5 Ne4 23.Nxe4 dxe4 24.Nd2 Ba5!) 22... Nexd5 23.Qb3 Bxc2 24.Qxc2 Qa4 equal chances, quiet position .)
21... Nh5 22.Kh2?! (22.Bh2 White has a slight advantage was forced.)
22... Nxg3 23.fxg3 (23.Kxg3? f5 Black has a moderate advantage .)
23... Kh7 24.Nd4 Qa5 25.N2f3 Qxc3 26.bxc3 Rb8 Now Black is playing under equal terms as White managed to loose all her advantage.
27.g4 b4 28.c4 (28.Nf5 Bf2 29.Re2 Bxf5 30.exf5 bxc3 31.Bc2 Nxd5 32.Rxf2 Rb2 33.f6+ Kg8 34.Ne1 Ne3 unclear position . )
28... Ra8 (28... f6!? .)
29.Nf5 Ng8 30.e5 dxe5 31.Nxe5 Bxf5 32.gxf5 Re8 33.Nd3 Rxe1 34.Nxe1 The position is more or less equal but time-trouble is on the cards (was always!).
34... Ne7 35.g4 Bd4 (35... c5 36.Nd3 Nc8 was good enough to draw.)
36.Nd3 Bc3 37.c5! Kg7 38.d6 cxd6 39.cxd6 Nc6 40.Ba4 Nd8 41.Kg2 Kf8 (41... Kf6 also keeps the draw in hand.)
42.Nc5 Bd2? (42... Bd4 43.Na6 Bc3 44.Kf3 Nb7 equal chances, quiet position .)
43.Kf3? (43.Nd7+ Kg7 44.f6+ Kg8 45.Nb6 White has a moderate advantage .)
43... Bf4 44.d7 Ke7 45.Ke4 Bd6 46.Nb3 f6 47.Kd5 Bg3 48.Nd4 Bd6 49.Nb3 Bg3 50.Na5 Be5 51.Nc4 Bg3? (51... Bc7 equal chances, quiet position . Black should not allow the white knight to land on a5/b6-squares.)
52.Nb6 White has a moderate advantage Bc7? ( The final mistake. The only option was 52... Nb7 53.Kc6 Nd8+ 54.Kb5 Bf2 55.Nd5+ Kxd7 56.Nxf6+ Ke7 57.Nd5+ Kd6 58.Nxb4 White has a moderate advantage .)
53.Nc8+ Kf7 54.Kc4 Ba5 55.Kb5 Bc7 56.Kxb4 Nb7 57.Bb3+ Kf8 58.Kb5 Nd8 59.Bd5 Bf4 60.Kb6 Bg3 61.Na7 Ke7 62.Be6! Bf2+ 63.Ka6 Bxa7 (63... Kd6 64.Nc8+ Kc7 65.Ne7 White has a decisive advantage . I am not sure if Black resigned or lost on time as it was so crowded at that moment but there is little difference. History will recognize Kosteniuk as the first blitz-women winner of the 1st WMSG 2008!) 1-0
