A strategic move is one that influences the other person's choice, in a manner favorable to one's self, by affecting the other person's expectations on how one's self will behave. One constrains the partner's choice by constraining one's own behavior. The object is to set up for one's self and communicate persuasively to the other player a mode of behavior (including conditional responses to the other's behavior) that leaves the other a simple maximization problem whose solution for him is the optimum for one's self, and to destroy the other's ability to do the same.

DEFINE: Defines strategic moves in game theory as self-constraint that shapes an opponent's expectations rather than direct action.
