Best responses
A best response maximizes a player's payoff given opponents' strategies.
Normal-form games
Players, strategies and payoff functions define a normal-form game.
Backward induction
Reasoning backward from terminal choices solves finite perfect-information games under appropriate preferences.
Bayesian games
Players' private types and beliefs extend strategic analysis to incomplete information.
Dominant strategies
A dominant strategy is at least as good against every opponent choice, with strength depending on the definition.
