Following the Eastern Bloc boycott of the 1976 Chess Olympiad, Soviet-aligned nations including the USSR returned to compete in 1978. The Soviet team entered as heavy favorites, having dominated previous Olympiads, while Hungary assembled a strong squad under grandmaster Lajos Portisch to mount a serious challenge.
The 23rd Chess Olympiad, organized by FIDE, was held in Buenos Aires from October 25 to November 12, 1978. Hungary won the open tournament gold medal by a full point ahead of the Soviet Union, a significant upset. The United States claimed bronze. China made its Olympiad debut, finishing 20th with six untitled players.
Hungary's victory over the Soviets was one of the most notable upsets in Chess Olympiad history. China's debut, though modest at 20th place, marked the beginning of its development as a chess power; the country would go on to win the Chess Olympiad in 2014 and 2018, demonstrating the long-term impact of early international participation.
