23rd Chess Olympiad

The 23rd Chess Olympiad (Spanish: La 23a Olimpíada de ajedrez), organized by FIDE and comprising an open[1] and a women's tournament, as well as several other events designed to promote the game of chess, took place between October 25 and November 12, 1978, in Buenos Aires, Argentina.

After the boycott two years earlier, the Eastern Bloc countries were back, including the Soviet team who, as usual, were huge favourites——but in the end they had to settle for the silver medal.

Hungary, led by Lajos Portisch, caused quite an upset by taking the gold medals by a full point.

The Soviet team was back, and led by newly crowned world champion Chiburdanidze they secured the gold medals in a superior display, as well as all four individual board prizes.

On the reserve board, Akhmilovskaya won all of her ten games, the only perfect score in Olympiad history.
