Sofia Polgar: A Winner on Board
The Polgar sisters consist of Susan or Zsuzsanna (April 19, 1969), Sofia or Zsofia (November 2, 1974), and Judit (July 23, 1976). Judit is still active and is the highest rated woman ever. Susan was the Women's World Champion (1996-1999). Despite the FIDE president's recent claim that politics and sport should be separate, women other than Susan Polgar were given 100 rating points in order to knock Susan out of her number one rating among woman (1987). Later FIDE stripped Susan of her world title. Sofia had very good results by the age of five when she won the Hungarian Girls' Under-11 championship (1980). She continued as a winner for about 20 years until pursuing other interests, although she still teaches chess. Here is an example of her play in 1984 when she was nine years old. The site was Teteven, Bulgaria where a tournament was held annually in the summer. Her opponent was, I believe, Stefan Stefanov (not Sergei, as one source has it). The opening is the Sozin Variation of the Sicilian Defense.
