The Draughtsmen Clash(Le damier)

This film tells the story of the president of a fictitious African nation who spends a sleepless night playing checkers with a pot-smoking vagabond who claims to be the all-round champion. However, the rules of the game entail the opponents howling vulgar and foul obscenities at one another. The champion proceeds to insult, and trounce, the President. His reward, and his fate, will not surprise anyone.
