The 'Queen of Chess' who defeated Kasparov
Hungarian chess champion Judit Polgar started playing chess from a very young age and almost immediately it became clear she had a special talent for the sport.
As a young girl, she soon swapped playing people of her own age to experienced adult professionals around the world.
Initially, Polgar was dismissed by many in the sport as not up to the challenge of playing against men.
Then world champion Garry Kasparov was the most renowned player to question whether a woman could beat a man.
However, during the 2002 Russia versus the Rest of the World tournament, Polgar got the ultimate revenge by beating Kasparov. She was the first woman to do so.
Judit Polgar spoke to Witness about their rivalry and that historic moment in the sport of chess.
Witness is a World Service programme of the stories of our times told by the people who were there.
