Abstract 

In traditional game theory, strategies are equivalent with actions and mixed strategies are the only extension. As a new extension, strategies are interpreted as plans. Although most plans are not very interesting (like doing a certain action), some conditional plans are. For example, they enable cooperation in the Prisoners’ Dilemma.
