Round five report

According to regulations Hou Yifan had white pieces for the second time in a row

World Champion Anna Ushenina having less trouble with black than with white

Hou Yifan has just deviated from the previous game and played 8.h4, leaving Anna Ushenina pondering

The Ukrainian GM, ranked number 17 in the (female) world, has a daunting task ahead of her:

Anna, above with her seconds Alexander Khalifman and Anton Korobov, needs to win at least two
of the next five games against world's number two, who is rated more than 100 points above her

19-year-old challenger Hou Yifan has three black games left to play, but can coast to victory

Going into game five Hou Yifan gets white again. The reason for breaking color every four games is to prevent the same player getting white after every rest day. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 Ushenina employs her preferred Najdorf. She has a lot of experience in the line and a good feel for it. Besides it is one of the more daredevil lines for Black, a need of the hour for Anna. 6.Be3 e6 7.g4 h6 8.h4 In game four Yifan tried 8.Qf3 Qc7 9.h4 h5!?N Black got a comfortable game and it ended in a draw without much trouble 8...Nc6 8...h5 The interesting idea of countering White's h4 with h5 works better when White's queen is committed on the f3 square, as in the previous game. Here it doesnt work as well as White can deploy pieces better. 9.g5 Ng4 10.Qd2 Nc6 11.Nxc6 bxc6 12.Bf4 Qb6 13.0-0-0 Qxf2 13...Nxf2?? 14.Be3+- 14.Bxd6 Qxd2+ 15.Rxd2 Bxd6 16.Rxd6 With a nice endgame for white 9.Nxc6 bxc6 10.Qf3 h5 11.gxh5 11.g5?! Ng4 12.0-0-0 Rb8 and Black will generate play on the queenside, while its more difficult for White to do her bit against the black king. 11...Nxh5 12.0-0-0 Rb8 A gentle reminder to be slightly worried. 13.Bc4 Qf6 14.Qg2 Nf4 15.Qg5 e5! 16.Qxf6 gxf6 17.Bxf4 exf4 Three islands including tripled pawns (Jonathan Rowson called it a train without an engine)! Black clearly doesn't have the most gorgeous pawn structure. However the bishop pair, the open files and Whites weak h-pawn can balance it out, if Black creates quick counterplay. So it was crucial for Ushenina to play actively to neutralize the structural disadvantage. And...she does it well! 18.Ne2 Rb4 19.Bd3 f5!? A nice break 20.exf5 20.c3 Not sure what Anna had in mind for c3 but it possibly could have been Rxe4!? 20...Ra4 Possible but not delightful after 21.Nd4 Rxa2 22.Kc2 Avoiding rook enchange so as to create attacking possiblities on blacks king fxe4 22...Bd7 23.Nxf5 23.Bxe4 c5 24.Bd5 Looks dangerous for black 21.Bxe4 fxe4 22.Rde1 d5 23.f3 Bd6 The strong central pawns and double bishop is enough compensation. Enough to intimidate Hou Yifan too. 20...f3 21.Nc3 Computer suggestion 21.Ng1 Also leads to a comfortable position for black Bh6+ 22.Kb1 Bg7 23.b3 Rbxh4 24.Rxh4 Rxh4 25.Nxf3 Rf4 Though holdable but black's dark squared bishop wont make life easy for white 21...Bh6+?! 21...Rbxh4! This was Ushenina's chance! Keep it simple. The natural capture gives black to fight for some real advantage. 22.Rxh4 22.Rhe1+ Kd8 23.Ne4 Rh2 22...Rxh4 23.Re1+ Kd8 24.Ne4 d5 25.Nd2 Rh3 26.c3 Bc5 27.Rf1 Ke7 And if nothing else, black will trouble white for a long time. 22.Kb1 d5 23.a3 Rf4 24.Rde1+ Kd8 25.Nd1 a5?! 25...Bxf5 26.Bxa6 26.Bxf5 Rxf5 27.Ne3 Re5 28.Ng4 Rxe1+ 29.Rxe1 Bg7 is fine for black too 26...Rg4 27.Reg1 Rxg1 28.Rxg1 Bf4 29.Rh1 Bg5 Black will regain the pawn, but not much more. 26.Ne3 Rg8 27.h5 Bd7 28.Reg1 White goes in for a series of exchanges leading to perfect balance. A practical choice by Yifan. Rxg1+ 29.Rxg1 Rh4 30.Ng4 Rxh5 31.Ne5 f6 32.Nxd7 Kxd7 33.Rg3 Rh2 34.Rxf3 Even though the game continued for almost another 30 moves, its difficult to imagine any real chances for either side. Bg5 35.Ka2 Bh4 36.Kb3 Bxf2 37.Ka4 Bb6 38.b4 There you are, draw could have been agreed here. axb4 39.axb4 Kd6 40.Rg3 Rh1 41.c3 Bf2 42.Rf3 Rh2 43.Kb3 Ke5 44.Bc2 Kd6 45.Bd3 Kd7 46.Bc2 Rg2 47.Rd3 Rg4 48.b5 Rf4 49.bxc6+ Kxc6 50.Rd1 Rf3 51.Bd3 Bg3 52.Kc2 Kc5 53.Rf1 Re3 54.Ra1 Be5 55.Ra5+ Kc6 56.Ra6+ Kc5 57.Ra5+ Kc6 58.Ra6+ Kc5 59.Ra5+ Kc6 60.Ra6+ Kc5 61.Ra5+ Five more games to go and Hou Yifan has a commanding 3.5-1.5 lead. Anna gets white next game so expect some no-compromises fighting chess! ½–½
