FIDE Women's Grand Prix Ankara, 27.09.2012
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Be7 8.Qf3 Qc7 9.0–0–0 Nbd7 10.g4 b5 11.Bxf6 Nxf6 12.g5 Nd7 13.f5 0–0


Very new modern line,which was developed by the Chinese players.White tried different ways ,trying to launch fast attack 14.Qh5! It is one of the real novelties ,prepared by Tatiana with her older sister Nadezhda after they played few games in this line recently.And they played the same Ju Wenjun,who is World leading expert in this line! [Very logical seems to be 14.Rg1 b4 15.Nce2 e5 16.f6 (16.Nb3 f6 17.gxf6 Nxf6 18.Ng3 Bb7 19.Bd3 a5 20.Kb1 Rfc8? (20...d5!µ) 21.Nd2 Ba6 22.Ndf1 a4 with very sharp play, Bracker,F (2364)-Blomqvist,E (2454)/Barcelona ESP 2012) 16...exd4 17.fxe7 Re8 18.Nxd4 Ne5 19.Qf4 Rxe7 (19...Be6 20.Nxe6 (Nothing promised 20.Kb1 Rxe7 21.Nf5 Rd7 22.Rg2 Rad8 23.Ne3 d5 24.exd5 Bxd5 25.Nxd5 Rxd5 26.Rgd2 Rxd2 27.Rxd2 Rxd2 28.Qxd2 a5 with equal end, Kosteniuk,A (2439)-Ju Wenjun (2543)/Beijing CHN 2011) 20...fxe6 21.Rg3 Rab8 22.g6 h6 23.Kb1 a5 24.a4 Qxe7 25.Bb5 Rf8 26.Qd2 Rbd8 27.c3 bxc3 28.Qxc3 Qh4 Thanking to the powerfull Knight e5,Black has very active counterplay. Groszpeter,A (2481)-Idani,P (2473)/Kecskemet HUN 2012) 20.Nf5 Bxf5 21.exf5 a5 22.Rg2 Rb8 23.Qd4 Rb6 24.Qd5 a4 25.Qa8+ Rb8 26.Qxa4 Nd7 27.Qb3 Nc5 28.Qd5 b3 29.Bc4 (29.g6 bxa2 30.Qxa2±) 29...bxa2 30.Bxa2 Qb6 31.c3 White kept better chances, Kosintseva,T (2536)-Ju,W (2536)/Nalchik RUS 2011; One completely different plan is 14.fxe6 fxe6 15.Qe3 (15.Nxe6 Rxf3 16.Nxc7 Bxg5+ 17.Kb1 Rb8 18.Ne6 (18.h4 Bf6 19.N3d5 Bb7 20.Bh3 Nc5 21.h5 Bxd5 22.Nxd5 Re8 Blacks end is absolutely not worse, Istratescu,A (2627)-Salgado Lopez,I (2621)/Porto Carras GRE 2011; 18.Ne8 Nc5 19.Nxd6 Be6 20.Bd3 Rd8 21.e5 Bf4 22.Rhe1 Bxh2 23.Be4 Nxe4 24.Ncxe4 Bg3 25.Ng5 Bg4 26.Nxf3 Bxe1 27.Rxe1 Bxf3


with such powerfull Bishop,Black pawns must be more dangerous,Antal,T (2356)-Idani,P (2473)/Kecskemet HUN 2012) 18...Bf6 19.Rxd6 Rb6 20.Rxb6 Nxb6 21.Nd5 Bxe6 22.Nxb6 Be5 23.a4 Re3 24.Bd3 Rh3 25.axb5 axb5 26.Bxb5 Rxh2 27.Rf1 h5


once more-passed pawns are more important than material, Huschenbeth,N (2459)-Hamitevici,V (2411)/Chotowa POL 2010) 15...Qc5 16.h4 Nb6 17.Bh3 Bd7 18.Qg3 Qc4 19.Kb1 e5 20.Bxd7 Nxd7 21.Nd5 Bd8 22.b3 Qc5 23.Ne6 Qf2 24.Qh3 Rf3 25.Qf1 Kf7 26.Qxf2 Rxf2 27.Nxd8+ Rxd8 28.Rhf1 Rxf1 29.Rxf1+ Kg6 Black is not worse,because White pawns e4 and h4 are weak. Kosintseva,N (2560)-Ju,W (2536)/Nalchik RUS 2011] 14...b4


[It was possible to try to stop transfer of White Rook to the Kings side 14...Ne5 15.a3 Rb8 16.Rg1 Rd8 17.Rg3! but other Rook can make his way there too!] 15.Rd3! Typical sicilian transfer for direct Kings assault. 15...bxc3 [Very soft defence was 15...Bd8 16.Rh3 h6 17.Rg1 Qc5 18.gxh6 Qxd4 19.hxg7 with mate.] 16.Rxc3 Qb6 [One more option was 16...Qd8 17.Rg1 Ne5 18.Rh3 h6 19.Nc6! Nxc6 (19...Bxg5+ 20.Rxg5 Qf6 (20...Qxg5+ 21.Qxg5 hxg5 22.Ne7#) 21.Rhg3 hxg5 22.Rh3 Qh6 23.Ne7+ Kh8 24.f6!) 20.gxh6 Qa5 21.hxg7 Qe1+ 22.Qd1! with very nasty attack.] 17.Nc6


17...Re8? This move loses the game. [It was incredible lkong forced line ,analysed by the Kosintseva sisters,which would ended with a draw. 17...Bf6 18.e5!


18...g6! (18...dxe5 19.Rh3 h6 20.gxh6 Qf2 21.Kd1 g6 22.fxg6 Bb7 23.g7 Bxc6 24.Qg4 Kh7 25.gxf8N+ Nxf8 26.Bd3+ e4 (26...Kh8 27.Rf1 Qd4 28.Qxd4 exd4 29.Rxf6±) 27.Bxe4+ Bxe4 28.Qxe4+ Qf5 29.Qxf5+ exf5 30.Rf1 with better chances in the sharp endgame.) 19.Qh4 Bxe5 20.Ne7+ Kh8 (20...Kg7?? 21.f6+ Bxf6 22.Qh6+ Kh8 23.gxf6+-) 21.fxg6 fxg6 22.Nxg6+ Kg7 23.Qh6+ Kg8 24.Ne7+ Kh8 25.Ng6+ Kg8 26.Ne7+ with perpetual.] 18.fxe6 [It was possible another winning way 18.Nxe7+ Rxe7 19.f6 Re8 20.Rh3 Nf8 21.e5 Qb7 22.Rg1 Rb8 23.b3 Qa7 24.g6 fxg6 25.Rxg6 Rb7 26.fxg7 Rxg7 27.Rxg7+ Qxg7 28.Qxe8] 18...Ne5 [Other defence would leave White with great material advantage 18...Bxg5+ 19.Qxg5 Rxe6 20.Ne7+ Rxe7 21.Qxe7 Nf8 22.Bc4] 19.exf7+ Nxf7 20.Bc4


20...Be6 21.Bxe6 Bxg5+ 22.Qxg5 Rxe6 23.Ne7+ Kf8


24.Qd5! Simple double attack,which finishes the game. 24...Kxe7 25.Qxa8 Qf2 26.Qb7+ Kf6 27.Qxa6 Qf4+ 28.Kb1 Qxe4 29.Qf1+ Kg6 30.Rg3+ Veru useful conclusions from this game for young players.As great Mark Taimanov used to say -every work will be paid ,sooner or later! It means,that if young player analysed some variation deeply,but his conclusion was that it is not sufficient to achieve more than draw,it is still usefull to play this line.Because opponent ,probably did not put enough efforts into this research.So ,wins that player ,who knows the position better!Simple ,as that! 1–0
