Analysis from the 6th round
round6analysisDear chess lovers, you can find some spectacular moments of the sixth round below;

, Marie - Foisor, Cristina-Adela


White's position is clearly better, as in addition to kingside pawn majority their pieces are much more active. 48.e6! fxe6 49.Rxe6 Bh5 50.Re7! Rf8


.Rg7? Missing a chance to decide the game with [51.Ke5! Rg8 (51...Rf7 52.Rxf7 Bxf7 53.Kf6 Bh5 54.Ke7+-) 52.Bf4 Rg1 53.Ke6! Rf1 54.Rxc7+ Kd8 55.Rh7! Rxf4 56.Rxh5 Re4+ 57.Kf7+-] 51...Rf7 52.Rg8+ [52.Rxf7 Bxf7 53.Bh4!? (53.Ke5 Bh5! Only move to secure the draw! 54.Ke6 Bg4!) 53...c6 54.Ke5 b5 55.Kf6 Bh5 56.Ke7 (56.axb5 cxb5 57.cxb5 Kb7 58.Ke7 Kb6 59.f6 Kxb5 60.Be1 a4=) 56...bxc4 57.bxc4 Be2 58.f6 Bxc4 59.f7 Bxf7 60.Kxf7 Kb7=] 52...Kb7 53.Rd8 Bg6 54.Rd5 Bh7 55.Re5 Kc6


In this position with only few seconds left on the clock White has played 56.Bh6 and made an offer Black couldn't resist :)[However, White's position still looks winning to me - 56.Re6+ Kd7 57.Bf6! Black is practically paralyzed! A possible plan for White is illustrated in following line: 57...Bg8 58.Kg5 Bh7 59.Re3! Kd6 60.Rd3+ Kc6 61.Rd8 Kb7 62.Re8 Kc6 63.Re7 Rxe7 64.Bxe7 Kd7 65.f6 Ke8 66.Kh6 Bg8 67.Kg6! Bf7+ 68.Kh7! c6 (68...Be6 69.Kg7 Bf7 70.Bd8!+-) ] 1/2

 12.f3 [12.Qa3 Ne4 13.Rc1 g5 14.Bg3 Qb6 15.Nf3 f6 16.Nd2 Nxg3 17.hxg3 a5 and Black is fine, Ponomariov,R (2737)-Smeets,J (2651)/Nice 2010/] 12...Nh5 13.Ne2 Nxf4 14.Nxf4 Rb8 15.Qa3 Rb5 16.Rxc6


...Qb8? [16...Ra5 17.Qb3 Qb8 18.0–0 Rb5 19.Qa3 Rxb2 20.Rfc1 h6 21.Rc7 Rb7 22.Rxb7 Qxb7 23.g4 Bb1 24.Qb3 Qxb3 25.axb3 Ba2 26.Ra1 1/2 Vaisser,A (2568)-Tkachiev,V (2645)/Besancon 2006/] 17.b3± e5 An attempt to complicate the position, otherwise white is just a pawn up. 18.Ne2 Bd3 19.Qd6


...Qe8 Black switches to "all-in" mode, keeping the queens and hoping to get some attacking chances. Surprisingly enough, this method worked just fine! [19...Bxe2 20.Qxb8 Rfxb8 21.Kxe2 doesn't promise much for the pawn.] 20.dxe5 d4 21.exd4 Qa8 22.Rc7 Rd5 23.Qe7 a5 24.e6 White is playing good enough to keep the position winning, but [24.Nf4! Rxd4 25.Ne6 would just win more material without giving any counterplay!] 24...Rf5 25.Qd6 fxe6 26.Ng3 R5f6 27.Nh5 R6f7 28.Rxf7 Rxf7 29.Kd2 Bf5 30.Rc1


Well, White is still completely winning... 30...a4 31.b4 Qe8 32.Ng3 [32.g4! Rd7 (32...Bg6 33.Nf4) 33.Qe5 Bg6 34.Nf4 Bf7 35.b5+-] 32...Rd7 33.Qf4 Bg6 34.Rc5 Qd8 35.Ke3 h6 36.Ne2 a3 37.Qe5 Bb1 38.Nc3 Bf5 39.g4 Bg6 40.Ne4 Kh7 41.g5 h5


.h4?! [42.Qxe6!? Rxd4 43.Rc8 Rxe4+ 44.fxe4 Qxg5+ 45.Kf3+-] 42...Qb6 43.Rb5 Qa6 44.Qb8 Rf7 45.Nd2 Qa4 46.Nb3 Rf8 47.Qb7 Rf7 48.Qb8 Rf8 49.Qb6 Qa8


Black's position has significantly improved and White is already facing some technical problems. 50.Qb7 Qd8 51.Qc6?! Be8 52.Qc2+ Bg6 53.Qc3 Qe7


.Ke2?! It has to be said that White's task is already far from being easy, as both [54.Kf2 Be4 55.Nd2 Bd5; and 54.Re5 Qf7 would offer Black descent compensation for material.] 54...Rf4 55.Rb8?! [55.Qe1 Qd6 56.Ke3 Bc2! 57.Re5 Rxd4 58.Nxd4 Qxe5+ 59.Kd2 Qxd4+ 60.Kxc2 Qb2+ 61.Kd3 Qxa2 62.Qe4+=] 55...Rxh4 56.Qc8? Based on miscalculation. [56.Qc5! was the only move to keep the position balanced.] 56...Rh2+ 57.Ke1 Bc2?! [57...Bf5! 58.f4 Rxa2 59.Na5! Planning Nc6 and Ne5. 59...Ra1+ 60.Kf2 a2 61.Nc6 Rf1+ 62.Ke3 Re1+=] 58.Nd2?! [58.Nc5!? Bf5! 59.Nd7 Rh1+ 60.Kf2 Rh2+ with perpetual, as White has to avoid 61.Kg3? Qxg5+ 62.Kxh2 Qh4+ 63.Kg2 Bh3+!–+] 58...Rh1+ 59.Kf2 Rh2+ 60.Ke1 Rh1+ 61.Kf2 Rh2+ 62.Ke1 Bd3


.f4? Final mistake! [White could survive with artificial 63.Qh8+! Kg6 64.Rg8, restricting black queen‘s possibilities] 63...Qd6! Finally black queen reaches her goal - to go on date with White's monarch! 64.Qg8+ Kg6 65.Nf3 [65.Qe8+ Kf5 66.Qf8+ Qxf8 67.Rxf8+ Kg4 and White is helpless.] 65...Rh1+ 66.Kf2 Rf1+ 67.Kg2 Rxf3! 68.Kxf3 Qd5+ 69.Kg3 h4+! 70.Kxh4 Qh1+ 71.Kg3 Qe1+ 72.Kh3 Bf5+ 73.Kg2 Be4+ 74.Kh3 Qh1+ 75.Kg3 Qg2+ 76.Kh4 Qf2+ 77.Kh3 Bf5# 0–1

Hoang, Thanh Trang - Girya, Olga


White had played 36. Ne5-d7, pretending she's got some tactical treats... 36...Qb5? Perhaps made in a timetrouble, this move leads to very hard endgame. [There was nothing wrong with 36...Qc6 37.Nf6+ (37.Ne5 Qc5=) 37...Kg7! 38.Qxd6 Qc2+ 39.Kf3 Kxf6=] 37.Qxb5 Nxb5 38.fxg5 Nc3+? [More resistant would have been 38...hxg5 39.Kd3 Nd6 (39...Nc3 40.a4!+-) 40.Ne5 f6 41.Nc6 Nb7 42.f4±, nevertheless I believe White should be able to win this.] 39.Kd3 Nxa2 40.gxh6 Kh7 41.Ne5 f6 42.Nc6 Kxh6 43.Nxa5 The rest is easy. 43...Kg5 44.Nc6 Kg4 45.Kc4 e5 46.Nxb4 Nxb4 47.Kxb4 e4 48.Kc4 Kf3 49.Kd4 f5 50.Ke5 1–0

Lahno, Kateryna - Ziaziulkina, Nastassia

1.c4 Nf6 2.Nc3 e5 3.Nf3 Nc6 4.g3 Bb4 5.Bg2 d6 6.0–0 0–0 7.Nd5 Bc5


.d4?! A dubious attempt to complicate matters. [Indeed, routine 8.e3 a6 9.d4 Ba7 doesn't promise White too much.] 8...Nxd4 9.Bg5 [9.Nxd4 Bxd4 10.Bg5 c6 11.Nxf6+ gxf6 is somewhat similar to the game.] 9...Nxf3+ [9...c6 10.Nxf6+ gxf6 11.Bh6 Nxf3+ 12.exf3 Re8 13.f4 Qd7 14.Qd2 Qg4 15.b4 Bd4 16.Rac1 Be6 17.b5 Rac8 18.fxe5 dxe5 19.bxc6 bxc6 20.c5 Red8 21.Qa5 f5 22.Kh1 Kh8 23.Bxc6 Rg8 24.Qa4 Qh5 25.Bd2 Bd7!! 26.Bxd7 Qf3+ 27.Kg1 Rxg3+! 0–1 Adorjan,A (2565)-Miles,A (2570)/Linares 1985/MCL] 10.Bxf3 c6 11.Nxf6+ gxf6 12.Bh4 Kg7 13.e4 Be6


14.Bg4? Logical follow up of the previous strategy - White is trying to complicate the game as much as possible. However, this move could lead to disaster... [Modest 14.Rc1 was objectively better, even taking into account White's compensation seem doubtful - 14...Qd7 , followed by f6-f5 under favorable circumstances.] 14...Qd7? [Black could grab a second pawn - 14...Bxc4! 15.Bf5 (15.Re1 Be6 16.Bxe6 fxe6 17.Qg4+ Kf7 18.Qh5+ Ke7 19.Qxh7+ Rf7 20.Qh5 Qh8 and Black has a huge advantage.) 15...Bxf1! 16.Qg4+ Kh6 17.Rxf1 Rg8 and I failed to find anything concrete for White - 18.Qh3 Kg7 19.Qg4+ Kh8 20.Qf3 (20.Qh5 Rg6–+) 20...Rg7 followed by Qe7, Rag8, Rg6 and Kg7.] 15.h3 d5? Not the best idea, as now white rooks getting a nice occupation on open "c" and "d" files. [15...Bxg4! 16.hxg4 Qe6 17.Qf3 Rg8! 18.Kg2 Kf8 19.Bxf6 Rxg4 and Black keeps an edge.] 16.cxd5 cxd5 17.Rc1 b6 18.Qf3 Be7 19.Bxe6 fxe6 20.Qg4+ Kh8 21.exd5 f5 22.dxe6 Qxe6 23.Qh5 Bxh4 24.Qxh4


After a sequence of more or less forced moves White has got a slight advantage as black king's position is a bit more vulnerable. 24...Rf7 [Black could try to swap a pair of rooks with 24...Rac8!? ] 25.Rfd1 Rg8 26.Rd8 Qe7 27.Rxg8+ Kxg8 28.Qh6 Qd7 29.Rc6 Black has no counterplay, so it's really hard to defend this kind of positions, especially being short on time. The rest of the game was affected by mutual timetrouble. 29...e4 30.Rd6 Qe7 31.Qd2 f4 32.gxf4 Qh4 33.Rd8+ Kg7 34.Rd7 Qf6 35.Rxf7+ Kxf7 36.Qd5+ Kf8 [36...Qe6!? 37.Qb7+± (37.Qxe6+? Kxe6 38.Kg2 Kf5 39.Kg3 b5–+) ] 37.Qxe4 Qxb2 38.Qa8+ Kg7 39.Qxa7+ Kg6 40.Qa4 Kf5 41.Qd7+ Ke4 [41...Kxf4 42.Qg4+ Ke5 43.Qg7+–+] 42.Qe6+ Kd3 43.Qe3+ Kc4 44.Qe4+ Kc5 45.Qe5+ 1–0
