12.e4 [Here was very serious alternative 12.Bd2 preparing recently popular blockading plan with b2-b4.] 12...e5 13.dxe5 [Another main theoretical move was 13.Bg5 exd4 14.Rxd4 Ne5 15.g3 Nxf3+ 16.Bxf3 Be5 17.Rd2 Rad8 18.Rad1 a6 19.Bg2 c5 20.Nd5 Bxd5 21.exd5 Qd6 22.Be3 Nd7 23.b3 Rc8

New and good positional move,Black is not ready yet for tactical counterplay [15...Nf3+ 16.Nxf3 Qxf4 17.g3 (17.e5!?) 17...Bxf2+ 18.Kxf2 Ng4+ 19.Ke1 Qe3 20.Rd3 Qf2+ 21.Kd2 Nxh2 22.Nxh2± Nosenko,A (2509)-Savinov (2482)/Chernigov 2005; Another option was immediate counterplay on d file 15...Rad8 ] 16.Bg3 [Good positional move ,as other two tempting move candidates were more aggressive 16.Nf5 ; 16.Rac1] 16...Qb6
17.Nf3?! [Nothing special promised 17.Nb3 Bf8 18.a4 a6; But much more agressive was 17.Nf5 but Kubra did not like 17...Re6 but she did not calculate the developments 18.a4 a6 19.axb5 axb5 20.Rxa8+ Bxa8 21.Qd2 with much better play.] 17...Nfg4 [Here was possible forced trtansfer into equal Rook end 17...Nxf3+ 18.Bxf3 Bd4 19.Ne2 c5 20.Nxd4 cxd4 21.e5 Bxf3 22.gxf3 Rac8 23.Qd2 Nh5 24.Qxd4 Qxd4 25.Rxd4 Nxg3 26.hxg3 Rxe5 27.a4 a5!] 18.Bf1 a6 [Not logical was to strenghten Whites center 18...Nxf3+ 19.gxf3 Ne5 20.Bg2 Bd4 21.a4 a6 22.Ne2] 19.Nxe5 [Better was to centralize Rook first 19.Rac1 ] 19...Nxe5 20.Rac1 Bf8 21.h3 Whites plan is to roll her pawn majority on the Kings flank ,as try to dominate d file would be unsuccessfull [21.Rd2 Rad8 22.Rcd1 Rxd2 23.Qxd2 Bc8] 21...Rac8 22.Kh2 c5 23.f4 Risky,here it was possible to disturb opponents pawn chain [23.a4] 23...Nc6 24.Nd5 [Very sharp position would arouse after 24.e5 Nd4 25.Qf2 f6 26.Bd3] 24...Qd8 25.Qf2 Nd4
26.b4 White tries to weaken opponents pawn,but another way was probably better [26.a4!?] 26...Rxe4 27.Nc3 Re7 28.Bh4 f6 29.Ne2 Rd7 30.Nxd4 Rxd4 31.Be2! In difficuly situation White best chance is to try to use the weakness of White squares 31...Qe7 32.Bg4 Rcd8?! [More precise was 32...Rxd1 33.Rxd1 Rd8 34.Rxd8 Qxd8 35.bxc5 Qc7] 33.bxc5 Rxd1 34.Bxd1 Rc8?! [Possible was to stop White passed pawn and to try to use d file 34...Bc6 ] 35.Bb3+ Kh8
36.Qd2? [Correct was 36.Qg3 Rxc5 37.Rxc5 Qxc5 38.Bxf6 Qf5 39.Be5 with powerfull positions of both Bishops] 36...Qe4 37.Bc2 [Tempting 37.Re1 was powerfully met by 37...Rd8] 37...Qd5 38.Qe2? [White nad not to avoid slightly better endgame 38.Qxd5 Bxd5 39.Bf2 Bxa2 40.Bf5 Rc7 41.c6 Bd6 42.g3 Re7 43.Ra1] Now Black wins a pawn 38...Re8 39.Qf1 Bxc5 40.Bb3 Qd6 41.Rd1 Qc7 42.Bg3 Be4 [Possible was principial attack of the weakness 42...Bd6 ] 43.f5 Qb6 44.Be6 Rd8 45.Qe2 Rxd1 46.Qxd1 Bd4 47.Qh5
47...g6?! [More technical way of realization of advantage was 47...Qd8 48.Qf7 Bc5 49.h4 Bd6] 48.Qh6? [It was necessary to open Black King with sufficient counterplay 48.fxg6 Bxg6 49.Qd5] 48...Qc5 49.Qf4 [Once more better was 49.fxg6 Bxg6 50.Qd2] 49...Bg1+! 50.Kh1 Be3 Now Black threats become deciseive 51.Qb8+ Kg7 52.Kh2 Qc2 53.Qc7+ Qxc7 54.Bxc7 Bxf5 With two extra pawns endgame is easily won 55.Bd5 Bd3 56.Kg3 Bc4 57.Bb7 b4 58.Kf3 Bc5 59.Ke4 Bxa2 60.Bxa6 Kf7 0–1
