Women's World Chess Championship 2011

The Women's World Chess Championship 2011 was the 35th of its kind. It was organised by FIDE and was played in a match format between the defending champion and a challenger, determined via the FIDE Grand Prix series.

On 8 August 2011 the match was awarded to Tirana, Albania. The prize fund was $200,000. The match took place from 13 to 30 November 2011. Champion Hou Yifan retained her title, defeating challenger Koneru Humpy by 5½ - 2½.

Match format
The match was scheduled to be played over 10 games with classical time controls: 90 minutes for first 40 moves with added 30 minutes for the rest of the game and a 30-second increment per move starting from the first move.

Koneru Humpy played White in the first game. Colours then alternated, except after game 4. The two players were ranked second and third in the world at the time, behind only Judit Polgár.

Should the match have been tied after ten games, tie-breaks would have kicked in. Those were:
 * Up to four rapid games (25 minutes per player with a 10-second increment from the first move)
 * two rapid games (5 minutes per player with a 3-second increment from the first move)
 * One armageddon game that Black only needs to draw to win the match (5 minutes for White and 4 minutes for Black with a 3-second increment from move 61)
