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. Strategic moves can either be unconditional moves or response rules. 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. Credible moves should also be observable to the other players.
Strategic moves are not warnings or assurances as they are merely statements of a player's interest, rather than an actual commitment from the player.
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.
Famous quotes containing the words strategic and/or move:
“Marriage is like a war. There are moments of chivalry and gallantry that attend the victorious advances and strategic retreats, the birth or death of children, the momentary conquest of loneliness, the sacrifice that ennobles him who makes it. But mostly there are the long dull sieges, the waiting, the terror and boredom. Women understand this better than men; they are better able to survive attrition.”
—Helen Hayes (19001993)
“There is not a subject in which I take a deeper interest than I do in the development of Alaska, and I propose, if Congress will follow by recommendations, to do something in that territory that will make it move on.”
—William Howard Taft (18571930)
