Strategic move
A strategic move in game theory is an action taken by a player outside the defined actions of the game in order to gain a strategic advantage and increase one's payoff. The key characteristics of a strategic move are that it involves a commitment from the player, meaning the player can only restrict her own choices, and that the commitment has to be credible, meaning that once employed it must be in the interest of the player to follow through with the move. The term was coined by Thomas Schelling in his 1960 book, The Strategy of Conflict, and has gained wide currency in political science and industrial organization.
Strategic moves manipulate the rules of the game to a player's advantage. They can be either unconditional moves or response rules. A response rule is a conditional strategic move which prescribes your action as a response to the others´ moves. Although you act as a follower, the commitment to the response rule must be in place before others make their moves. Response rules can either be threats or promises.
