 Virtually all aspects of game theory provide contacts between logical and probabilistic perspectives. Clearly, this is true for the different representations of knowledge, beliefs and their dynamics just discussed. Other contacts occur at the level of game forms, cf.  Section 2,  where probabilities enrich the space of strategies. The resulting mixed moves require players to expand their preferences to mixed outcomes, cf.  Section 3.  Finally, at the level of reasoning about game play, cf.  Section 4,  probabilistic beliefs play a role in solution techniques such as dominance or expected utility based reasoning.
