In card games, players have an incomplete information about the other players’ cards. This is actually the case in most games. WebIn game theory, a Bayesian game is one in which information about characteristics of the other players (i.e. payoffs) is incomplete. Following John C. Harsanyi 's framework, a …

Suppose that player 2 is uncertain whether
In game theory, a Bayesian game is a game that models the outcome of player interactions using aspects of Bayesian probability. Bayesian games are notable because they allowed, for the first time in game theory, for the specification of the solutions to games with incomplete information.
