👉 Countergambit is a concept in game theory that refers to two players who engage in a series of games, each involving a random selection from a set of mutually exclusive and exhaustive options. The goal of these games is to determine the winner based on their strategy or performance, rather than solely relying on chance or luck. In Countergambit, the rules are designed so that both players can learn from each other's strategies, and there is no inherent advantage for one player over the other.
