Optimal play refers to the strategy of making the best possible moves in a game to maximize the chances of winning. This concept is often applied in games like chess, where players analyze positions to determine the most advantageous actions. The goal is to minimize mistakes and exploit the opponent's weaknesses. In many games, optimal play can be mathematically calculated, leading to a theoretical understanding of perfect strategies. For example, in tic-tac-toe, if both players use optimal play, the game will always end in a draw. Understanding optimal play helps players improve their skills and decision-making.
