Very important game of 1 and 2 seeded players in the tournament. Anna told, that she did not win against Hou Yifan for a long time - last victory was in Krasnoturjinsk in 2007! So, the game was very principial and Anna decided not to play main lines, but to chose side line, which promised White good results recently. Even World Champion Anand lost twice here.
