Women in chess

Women represent a small minority of chess players at all ages and levels. Female chess players today generally compete in a mix of open tournaments and women's tournaments, the latter of which are most prominent at or near the top level of women's chess and at youth levels. Modern top-level women's tournaments help provide a means for some participants to be full-time professional chess players. The majority of these tournaments are organized by the International Chess Federation (FIDE) and revolve around the World Championship cycle, which culminates in a match to decide the Women's World Chess Champion. Beyond those events, among the most prominent women's tournaments are women's and girls' national and continental championships.

Women were generally not permitted to join chess clubs until the early 1900s. Once allowed in, they were largely limited to competing against other women. Around this time, Vera Menchik became the inaugural Women's World Chess Champion and was the first woman to compete in top-level tournaments with the best players in the world in the late 1920s. After her death, the Soviet Union dominated women's chess, winning every Women's Chess Olympiad they played from its inception in 1957 through 1986. Soviet players Nona Gaprindashvili and Maia Chiburdanidze from Georgia became the first two women to earn the Grandmaster (GM) title, and were the next two women after Menchik to compete in high-level open tournaments.

The Polgar sisters ended Soviet domination of women's chess as Susan Polgar became No. 1 in the world among women in 1984 and all three led Hungary to a gold medal at the 1988 Olympiad. Judit Polgar established herself as the strongest women's chess player of all time, reaching No. 8 in the world overall. The turn of the century saw a substantial increase in the number of women to earn the GM title. Among these new GMs, Hou Yifan has been the only other woman to reach the overall top 100 and regularly compete in high-level open tournaments. Since the 1990s, China has dominated the Women's World Championship with six different champions, including the reigning champion Ju Wenjun.

The low number of women to reach the top level of chess has created a lot of interest as to why women historically have not had more success. There is no evidence that women are innately disadvantaged at chess. It has been demonstrated statistically that the low numbers across all levels can largely account for the lack of women at or near the top. The general paucity of women in chess has contributed to women commonly being the subject of sexism, harassment, and sexual harassment, factors also thought to contribute to women achieving less or leaving chess early. Beyond playing chess, women also take on other roles such as being a coach or an arbiter. Two chess professions with a smaller participation gap are commentators and live streamers.
