　　1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Qxd4 Nf6 5.Bg5 e5?

　　We must say that Nana was not in good shape, after feeling not well during previous night and only this is a reason not to criticize her for this move!

　　[In last period GM level players played few interesting games 5...Nc6 6.Bb5 Bd7 (6...Qa5+?! 7.Nc3 Qxb5 8.Nxb5 Nxd4 9.Nfxd4 Rb8 10.Bxf6 gxf6 11.Nxa7 Bd7 12.c4 Rg8 13.g3 f5 14.Nxf5 d5 15.Nb5 dxc4± White have clear advantage 16.Nc7+ Kd8 17.Nd5 Rg6 18.0–0–0 ......1–0 Zhigalko,S (2540)-Negi,P (2515)/Kirishi 2007/ CBM 118 ext (45)) 7.Bxc6 bxc6 8.Nc3 Qb6 9.Qd2 h6 10.Bxf6 gxf6 11.b3 f5 12.e5 Bg7 13.0–0 dxe5 14.Rad1 Qc7 15.Na4 e4 16.Nd4 c5 17.Nxf5 Bxf5 18.Qd5 e6 19.Qxa8+ Ke7 0–1 Vescovi,G (2648)-Ghaem Maghami,E (2558)/playchess. com INT 2004/CBM 099 ext]

　　6.Bxf6 gxf6

　　[Worse is 6...Qxf6 7.Qe3 Qd8 8.Nc3±]

　　7.Qe3 Be6 8.Nc3 Nc6 9.Be2 a6 10.a3?!

　　It's difficult to understand such a prophylactic! why? If white is going to make castle on long side then "a3" looks not so good.

　　10...Rc8

　　[Black has an interesting alternative 10...h5!? 11.0–0 f5 12.exf5 Bxf5 with similar play like in Sveshnikov system]

　　11.0–0–0 Bg7 12.Kb1 0–0 13.g4!

　　This is good move! fixing black week point and this is black color bishop

　　13...b5

　　Of course black must push pawn "b", hoping to organize contra attack

　　[13...Bxg4?! 14.Rhg1 f5 15.exf5 Bxf5 16.Ne4 Nd4 17.Nxd4 exd4 18.Rxg7+ Kxg7 19.Qxd4+ f6 20.Bd3 and white have fantastic compensation for exchange]

　　14.Rhg1 b4 15.Nd5

　　Everything is under control!

　　15...Qa5 16.a4!

　　Xu Yuhua is playing very well, like in 2006, when she become a world champion [Why not 16.g5 ?, Maybe Xu don't like, that black must play only moves and it's easy to find them? 16...f5 17.Nf6+ Kh8 18.exf5 Bxf5 19.Bd3 e4 20.Bxe4 bxa3 21.Qxa3 Qxa3 22.bxa3 Rb8+ 23.Kc1 Bxf6 24.Bxf5 Bb2+ and also in final position white has just small advantage!]

　　16...Qxa4 17.b3 Qa3 18.Bc4

　　[If 18.Nb6 Black have a very strong move 18...Na5 19.Nxc8 Rxc8©; If 18.Nd2 then 18...Bxd5! 19.exd5 Nd4 20.Nc4 Nxc2!! 21.Kxc2 Qa2+ 22.Kc1 e4©; 18.g5 f5 19.Nf6+ Kh8 20.Rxd6 Na5 21.Nxe5]

　　18...Na5!?

　　This is not a best move, but in time trouble sometimes such a move is bringing victory!

　　[Best move in this position is 18...Bxd5 But not easy to make, when especially you have short time]

　　19.Ne7+ Kh8 20.Bxe6?

　　[Better is to take exchange 20.Nxc8 Nxc4 21.bxc4 Qxe3 22.fxe3 Rxc8 23.Rxd6 Bxc4 24.Rgd1 With clear advantage for white]

　　20...Rc3 21.Rd3 fxe6 22.Rxc3

　　[Of course all chess programs show this move, but for players during game and time trouble it's extremely difficult to see such a possibility! 22.Nh4! h6 23.Rxc3 bxc3 24.Nhg6+ Kh7 25.Qxc3 Rb8 26.Rg3 White is defending "b3" and there position is much better]

　　22...bxc3 23.Qxc3 Nb7

　　This is typical zeitnot mistake

　　[23...d5! 24.exd5 Nxb3 25.Qxb3 Qxe7 26.dxe6 Qa7! With attack!]

　　24.Rd1?

　　White is answering also with mistake

　　[White can win game in one move! 24.Nh4!! threatening Ng6]

　　24...d5 25.Nc6 d4 26.Qb4 Qxb4 27.Nxb4 Nc5 28.Re1?

　　[Better was 28.Nd2 but anyway black has much better position 28...Bh6 29.Nd3 Nxd3 30.cxd3 f5 31.gxf5 exf5 32.exf5 Bxd2 33.Rxd2 Rxf5]

　　28...f5

　　[Nana missing this simple move! 28...Rb8 29.Nd3 Nxd3 30.cxd3 Rxb3+µ]

　　29.exf5 e4 30.Ng5?

　　[In 20seconds it's difficult to make this move 30.fxe6 ]

　　30...exf5 31.gxf5 d3!

　　This is Dzagnidze! she feel initiative very well

　　32.Ne6?

　　[Better is 32.cxd3 Bc3 33.Nxa6 Nxa6 34.Rxe4]

　　32...Nxe6 33.fxe6 Bc3 34.Rd1

　　Rest it's clear

　　34...Bxb4 35.cxd3 exd3 36.Rxd3 Rxf2 37.Rd8+ Kg7 38.Ra8 a5

　　Very exiting game, which bring full point to Lider!
