Хоу Ифань
Beginning from 2010, the Women's World Chess Championship would be held annually in alternating formats. In even years a 64-player knockout system would be used, in the odd years a classical match featuring only two players would be held. The 2011 edition was between the 2010 champion Hou Yifan and the winner of the FIDE Women's Grand Prix 2009–2011. Since Hou Yifan won the Grand Prix, her challenger was the runner-up, Koneru Humpy.
