We study incomplete information games with ambiguity averse players. Our focus is on equilibrium concepts satisfying sequential optimality each player's strategy is optimal at each information set given opponents' strategies. We show sequential optimality, which does not make any explicit...

Since at least de Finetti [7], preference symmetry assumptions have played an important role in models of decision making under uncertainty. In the current paper, we explore (1) the relationship between the symmetry assumption of Klibanoff, Mukerji and Seo (KMS) [21] and alternative symmetry...
