poker

Any of several card games in which a player bets that the value of his or her hand is greater than that of the hands held by others. Each subsequent player must either equal or raise the bet or drop out. The pot is eventually won by either the player showing the best hand when it comes to a showdown or the only player left when everyone else has dropped out, or “folded.” In this case the winner need not show his hand and could conceivably have won the pot with a lower hand than any other at the table. It is for this reason that poker is described as a game of bluff. Three principal forms of the game have developed: straight poker, in which all cards of the standard five-card hand are dealt facedown; stud poker, in which some but not all of a player's cards are dealt faceup; and community-card poker, in which some cards are exposed and used by all the players to form their best hand. In draw poker, the main variant of straight poker, cards may be discarded and additional cards drawn. The traditional ranking of hands is (1) straight flush (five cards of the same suit in sequence, the highest sequence—ace, king, queen, jack, ten—being called a royal flush), (2) four of a kind, (3) full house (three of a kind, plus a pair), (4) flush (five of a single suit), (5) straight (five in sequence), (6) three of a kind, (7) two pair, (8) one pair.
