 As pointed out earlier on, this entry will only mention how knowledge is implicit in game structures but will not delve into the study of epistemic preconditions of rational play. Related entries devoted to  epistemic logic  (Hendricks &amp; Symons 2006),  dynamic epistemic logic  (Baltag &amp; Renne 2016), and in particular  epistemic game theory  (Pacuit &amp; Roy 2015) explore in depth the role of knowledge in decision-making. A treatment of modal logics for games which focuses instead on the role of information is Hoek &amp; Pauly 2006.
