The chicken game, also called the hawk-dove or snowdrift game, is a two-player game in which each player chooses whether to yield or persist. Each prefers that the opponent yield, but the outcome in which neither yields is worst for both.
The game has two asymmetric pure-strategy Nash equilibria, in each of which exactly one player yields, and a mixed-strategy Nash equilibrium. Unlike the prisoner's dilemma, neither player always prefers persistence regardless of the opponent's choice.
