A85 Chernyshov Konstantin (RUS) - Hoang Thanh Trang (VIE) Budapest (Hungary) 2003

[#]In the beginning, I had to play against a young woman grandmaster from Vietnam. It turned out during my preparation that she was readily choosing a variation where I 'accidentally' found an interesting idea. 1.c4 f5 2.¤c3 ¤f6 3.d4 g6 4.h4 ¥g7 5.h5 ¤h5 6.e4 ¤f6 7.ef gf Previously White tried many continuations there except the following one:

8.¥g5!? e6 9.¥d3 ¤c6 10.¤f3 £e7 11.£d2 b6 It is quite difficult for Black to find a precise move order here. 12.O-O-O ¥a6 The black king is already prepared to evacuate to the queen's side, but... 13.¤d5! Just in time! If the e-file opens then the black queen perishes. 13...£d8 14.¤e3!?

[I understand that many players would have chosen 14.¦he1 , but this rook has to be on the king's side in order to participate in White's impending attack there.]

14...¤e7 15.d5 O-O 16.£c2 £e8 17.g4! A simple and efficient continuation. Then it all goes on all by itself. 17...¤e4 18.gf ed 19.¥e7 £e7 20.¤d5 £c5 21.¥e4 ¥c4 22.b4 £b5 23.a4 £a6 24.f6! It is all over. Perhaps, I successfully refuted the variation? [1:0]
