@UnityChess
Judit Polgar, pictured here, was the highest scoring member of her team. Following the defection of Elena Akhmilovskaya Donaldson after the tenth round, the Hungarian team triumphed, winning the tournament by half a point. Akhmilovskaya would later become a three-time U.S. Womenβs Chess Champion (1990, 1993, and 1994).
