WGP Geneva: Lahno in the sole lead

[Event "Fondation Neva Women's Grand Prix"] [Site "Geneva"] [Date "2013.05.06"] [Round "4.4"] [White "Hou, Yifan"] [Black "Cmilyte, Viktorija"] [Result "1-0"] [ECO "B52"] [Annotator "MIKHALCHISHIN"] [PlyCount "69"] [EventDate "2013.??.??"] [WhiteClock "0:03:09"] [BlackClock "0:01:04"] {Hou Yifan lost in round three against an outsider from Mongolia, got a strong reprimend from her mother, who accompanies her to most tournaments and was ready to strike back. But she had not played too convincingly against Viktoria Cmilyte in the past - we remember fantastic win of Viktoria in a Sicilian last year in Kazan. Viktoria used the same approach as I taught my pupil Betul Yildiz in recent years: Hou Yifan is fantastic, fine technical player, and the only way to play successfully against her is to challenge her from the start. It means to attack as soon as possible. But it is tremendousely difficult. You have to show her that you are not afraid of her.} 1. e4 c5 2.
