At the conclusion of the betting round, a player must place the player's hand face upward on the table at the showdown as follows: (1) If there has been a bet on the final round, the player who made the bet must show first; (2) If there have been one or more raises on the final round, the player who last raised must show first; (3) If the final round has been checked by all the players, the player who acted first must show first; (4) The subsequent order of showing hands is clockwise around the table from the player who must show first; and (5) Suits of cards do not count in the ranking of hands at the showdown.
