The U.S. Women's Open Championship is an open chess tournament that has been held irregularly. From 1934 through at least 1966 it was held in conjunction with the annual U.S. Open Chess Championship. After some years of inactivity, the event was reinstituted in 2009.
History From 1934 through 1950 and in 1954, the women's tournaments were held as a round-robin tournament in conjunction with the U.S. Open. From 1951 through 1978, with the exception of 1954, the women played in the U.S. Open with the title U.S. Women's Open Champion being awarded to the woman with the highest score.
After 1978, the title was not awarded until 2009. That year the event was held again with sixteen players in a six-round tournament, in conjunction with the U.S. Senior Open Chess Championship and two other tournaments. Chess Life incorrectly called it the first U.S. Women's Open Championship. The highest-placing US citizen qualified for the U.S. Women's Chess Championship.
The event was then not held until 2015, when it was held in conjunction with the National Open in Las Vegas. It has been held each year since then, except for 2020 due to the COVID-19 pandemic.
