The Attacker. One of the strongest women players of her era, Graf challenged Menchik twice for the World Championship. Sharp, aggressive, and uncompromising. She played chess like a street fight.
Sonja Graf was one of the strongest female players of the 1930s and 40s, challenging Vera Menchik twice for the Women's World Championship. Sharp and aggressive, she played chess with a combative intensity that set her apart. Opponents had no time to breathe. After World War II she emigrated to Argentina and later to the United States, where she continued playing and teaching. Her autobiography 'Schach, mein Schicksal' (Chess, My Destiny) remains one of the most vivid accounts of chess life in the pre-war era.
Notable: One of the first women to write a chess autobiography. Her aggressive style earned her the nickname 'The Attacker' among contemporaries.
