Women's World Chess Championship

The Women's World Chess Championship (WWCC) is played to determine the women's world champion in chess. Like the World Chess Championship, it is administered by FIDE.

Unlike with most sports recognized by the International Olympic Committee, where competition is either "mixed" (containing everyone) or split into men and women, in chess women are both allowed to compete in the "open" division (including the World Chess Championship) yet also have a separate Women's Championship (only open to females). Notably however, the top-rated female player for over 20 years (with the highest FIDE rating in history of any woman), Judit Polgár, has never competed for the women's title.

The Women's World Championship was established by FIDE in 1927 as a single tournament held alongside the Chess Olympiad. The winner of that tournament, Vera Menchik, did not have any special rights as the men's champion did—instead she had to defend her title by playing as many games as all the challengers. She did this successfully in every other championship in her lifetime (1930, 1931, 1933, 1935, 1937 and 1939).

Menchik died, still champion, in 1944 in a German air raid on Kent. The next championship was another round-robin tournament in 1949–50 and was won by Lyudmila Rudenko. Thereafter a system similar to that of the men's championship was established, with a cycle of Candidates events (and later Interzonals) to pick a challenger to face the reigning champion.

The first such Candidates tournament was held in Moscow, 1952. Elisaveta Bykova won and proceeded to defeat Rudenko with seven wins, five losses, and two draws to become the third champion. The next Candidates tournament was won by Olga Rubtsova. Instead of directly playing Bykova, however, FIDE decided that the championship should be held between the three top players in the world. Rubtsova won at Moscow in 1956, one-half point ahead of Bykova, who finished five points ahead of Rudenko. Bykova regained the title in 1958 and defended it against Kira Zvorykina, winner of a Candidates tournament, in 1959.
