There are a variety of ways to describe the players’ knowledge and beliefs in an extensive game. The game models vary according to which epistemic attitudes are represented (e.g., knowledge and/or various notions of beliefs) and precisely how the players’ disposition to revise their beliefs during a play of the game is represented. Consult Battigalli, Di Tillio, &amp; Samet (2013); Baltag, Smets, &amp; Zvesper (2009); and Battigalli &amp; Siniscalchi (2002) for a sampling of the different types of models found in the literature.
