Showdown and Discarding Irregularities

A: If a player tables one card that would make a winning hand, the dealer should advise the player to table all cards. If the player refuses, the floor should be called. B: If a player bets then discards thinking they have won (forgetting another player is still in the hand), the dealer should hold the cards and call the floor (a Rule 58 exception). If cards are mucked and not retrievable and identifiable to 100% certainty, the player is out and not entitled to a refund of called bets. If cards are mucked and the player initiated a bet or raise not yet called, the uncalled amount will be returned.
