The most important concept in Game Theory is the notion of strategy.
A strategy is a complete contingent plan for a player in a game.
A complete contingent plan is a full specification of a player’s behavior, which describes the actions that the player would take at each of his possible decision points. In other words, a player’s strategy describes what they will do at each of their information sets.
