Chicken payoff ordering ($T>R>S>P$)

The Chicken payoff ordering describes a symmetric two-player bimatrix game in which aggression earns temptation $T$ against yielding, mutual yielding earns $R$, yielding to aggression earns $S$, and mutual aggression earns $P$, with the displayed strict ordering. Aggression is a best response to yielding, and yielding is a best response to aggression. Thus the two asymmetric action pairs are pure strategy Nash equilibria. The Hawk-Dove game has this ordering in its positive-resource regime where the damage cost exceeds the resource value. In the prisoner's dilemma, the ordering of $S$ and $P$ is reversed, making defection a strictly dominant strategy instead.
