Kuhn's Theorem

Kuhn's Theorem states that in dynamic games with perfect recall—where players remember all past actions and information—any decision-making strategy can be represented as if players choose their actions ahead of time, rather than adjusting them based on new information. Essentially, it allows analyzing complex, evolving decision scenarios by considering equivalent "pre-planned" strategies, simplifying the study of strategic behavior without losing the richness of how players might adapt during the game. This helps in understanding and predicting strategic interactions in situations like negotiations, auctions, or competitive contests.
