If a bet has been made and everybody else folds than no, but if the river card has been shown and more than one person stays in for the pot than as I have ever played if a person wants to collect that pot than they must show their hand. If I am wrong than please somebody let me know. If I have made a bet on the pot and no one else calls Than I never show my hand only for the fact that I don't like to give out anymore information than I absolutely have to.
