In poker, showdown is a situation where, if more than one player stays after the last betting round, the remaining players expose and compare their hand to determine the winner or winner.
To win any part of the pot if more than one player has a hand, the player must show all the cards face up to the table, whether they are used in the final hand played or not. The card speaks for itself: the true value of the player's hand is valid if the player incorrectly mentions the value of his hand. Because exposing a losing hand provides information to an opponent, players may be reluctant to expose their hands until after their opponents do so and will dirty their lost hands without exposing them. Robert's Rules of Poker states that the last player to take aggressive action with a wager or a raise is the first to show the hand - unless everyone checks (or all) in the last round of the bet, then the first player to the left of the button The dealer is the first to show the hand.
If there is a side pot, the players involved in the side pot should show their hands before anyone who is all just for the main pot. To speed up the game, the player holding the potential winner is encouraged to show the hand without delay. Any player that has been handled can ask to see any hand eligible to participate in the fight, even if the hand has been criticized. This option is generally only used when a player suspects a collusion or some other cheating by another player. When privileges are abused by a player (ie the player does not suspect cheating, but asks to see the card only to gain insight into the other player's style or betting pattern), he may be warned by the dealer, or even removed from the table..
There has been a recent trend in public card rules to limit a player's ability to request seeing lost hand lost at the showdown. In particular, some cardrooms only give the right to see lost hand lost if the player is asking to articulate concerns about the possibility of collusion. Under such rules, the player does not have an inherent right to see the copied hand.
