A "Pure Strategy" in game theory refers to a strategy where a player consistently chooses a specific action or decision in a given situation. This means that the player does not randomize their choices but instead follows a fixed plan. Pure strategies are often used in games where the outcomes are predictable based on the players' actions. In contrast to mixed strategies, where players may randomize their choices, pure strategies provide a clear and straightforward approach. They are particularly useful in scenarios like chess or tic-tac-toe, where players can anticipate their opponent's moves and respond accordingly.
