• Given an extensive game form, an equilibrium concept and a behavior strat- egy pro¯le, what parts of the game form are never relevant to check if the outcome of the strategy pro¯le is an equilibrium outcome of a game with that game form? What is left after removing the irrelevant parts is what we call essential. In this paper we essentialize a wide variety of equilibrium concepts and present several applications of our analysis.
