Michel Piccoli plays Akiva Liebskind, a Russian chess genius in the Swiss-filmed Dangerous Moves. He is pitted against Soviet exile Pavius Fromm (Alexandre Arbatt), who, since childhood, has dreamed of nothing but defeating Liebskind. Both men soon become obsessed with winning. Already suffering from a weak heart, Liebskind courts a coronary, while the increasingly paranoid Fromm is convinced that his opponent is spying on him from every corner. The KGB enters into the game by attempting to sabotage Fromm, hoping that by doing so they will discredit everyone who's ever publicly opposed the Soviet government. Dangerous Moves was the 1984 recipient of the Best Foreign-Language Picture Academy Award.
