Judit Polgár (born 23 July 1976) is a Hungarian Chess Grandmaster. She is generally considered the strongest female chess player of all time. In 1991, Polgár achieved the title of Grandmaster at the age of 15 years and 4 months, at the time the youngest to have done so, breaking the record previously held by former World Champion Bobby Fischer. She was the youngest ever player to break into the FIDE Top 100 players rating list, ranking No. 55 in the January 1989 rating list, at the age of 12. She is the only woman to qualify for a World Championship tournament, having done so in 2005. She is the first, and to date only, woman to have surpassed 2700 Elo, reaching a career peak rating of 2735 and peak world ranking of No. 8, both achieved in 2005. She was the No. 1 rated woman in the world from January 1989 until the March 2015 rating list, when she was overtaken by Chinese player Hou Yifan; she was the No. 1 again in the August 2015 women’s rating list, in her last appearance in the FIDE World Rankings.
