Best response (game theory) is the best strategy a player can do given what the opponent plays.
It is important to note that a player’s best response entirely depends on the other player’s action.
Per Suzuki (2025), player 1’s action is a best response to player 2’s action if player 1’s action maximises player 1’s payoff given player 2’s.
