Kateryna Lahno Vs Yifan Hou, Round 9 Women’s Grand Prix 2011 in Rostov, Russia: Ukrainian GM Kateryna Lahno played a great tournament, eventually finishing in clear 2nd place with 7/11 to Yifan Hou’s unstoppable performance with 8/11. This round 9 match-up made things interesting as Lahno gave the Chinese phenom her only loss of the tournament to try to catch up late. Hou’s opening led her to a difficult position as she was unable to achieve the dynamic compensation necessary for her inferior pawn structure. It’s tough to say exactly where black went wrong, although the forced complications after 17. …h4!? certainly did not work out well. Maybe a better plan for black would have been to double the rooks on the e-file, however white would be able to force through with e4 and achieve a dangerous space advantage and attack. Instead of the greedy 21. h3?! to hold on to the extra pawn, Lahno chose the aggressive 21. e4! and achieved a decisive kingside attack due to black’s lack of coordination. A great game and tournament by GM Lahno, although she was unable to catch up to Hou at the end.
