Strategies in game theory

Main article: Strategy (game theory)

In game theory, a strategy refers to one of the options that a player can choose. That is, every player in a non-cooperative game has a set of possible strategies, and must choose one of the choices.

A strategy must specify what action will happen in each contingent state of the game—e.g. if the opponent does A, then take action B, whereas if the opponent does C, take action D.

Strategies in game theory may be random (mixed) or deterministic (pure). That is, in some games, players choose mixed strategies. Pure strategies can be thought of as a special case of mixed strategies, in which only probabilities 0 or 1 are assigned to actions.

Strategy based games all have a similar objective where the player thinks through a sequence of solutions to determine the preferred favorite in order to defeat the opponent. Chess is a common strategy game played throughout the world.
