From Breaking Through by Susan Polgar and Paul Truong, page 126.
"I think (and my parents agree) that Sofia is the probably most talented of the three sisters. She was only 5 years old when she won her first national title at the under 11 Girls' Championship in Debrecen.
However, her problem always has been that she was somewhat lazy, and would give up fights more easily." This is apparent in her last game at Rome 1989 where she had won 8 games in a row, stood better in Game 9, drew and still, as an IM, achieved the fifth highest performance rating ever seen, 2879. According to Susan, the only thing she noticed that was different about Sofia in this tournament, was,
"Everything seemed normal during the tournament, except that Sofia had an exceptional appetite. She would eat a huge plate of some kind of pasta as an appetizer, followed by the main course (some kind of meat/fish with potato/rice and vegetables) and dessert each lunch and dinner for ten consecutive days."
It is reasonable to assume that the extra calories were coursing through her brain.
