Dangerous Moves (1984)

Two masters of chess duel each other not only in their game but also in their different ideologies. The veteran Akiva is a Soviet Jew and ferocious Communist, master of his game but also dealing with a declining health while the young and restless genius Pavius has defected to the West to escape from the Communism tentacles. Their differences will be put to test while they're both competing in the World Chess Championship, with a huge prize at stake just as much as the political ideologies behind those characters.
