A card game in which players compete for a sum of money (called the pot) by betting on the value of their hands, poker can be played socially for pennies or matchsticks or professionally for thousands of dollars. It is the most popular card game in the United States and has become a fixture on television, in casinos, and in the pages of newspapers and magazines. It is also one of the most common games played in private homes. Many variants of the game exist.
A standard deck of 52 cards is used for the game, but some games include extra cards called jokers. A standard pack contains four suits: spades, hearts, diamonds and clubs, and all are ranked as follows from high to low: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3 and 2. The card rank is determined by the number of matching cards in the hand. The highest hand wins the pot. Some games also have wild cards, which can take on any suit and rank (dueces or one-eyed jacks).
Most forms of poker are card games, but some are board games. A number of rules govern the way in which the cards are dealt and a specific rule determines how much may be wagered during each round. The rules of each game vary considerably, and some are subject to local customs and preferences. These variations are known as house rules and are not binding.
While no poker game is perfectly uniform, the rules that are agreed upon by a group of players are generally followed by everyone. This helps to create a sense of fair play and ensures that the outcome of each hand will be based on skill rather than luck. The rules of official poker do not restrict individual clubs or groups from making their own house rules, but these should be standardized and well-documented for clarity.
All players must keep their hands visible to all others at the table. A player’s chips must not be concealed under the hands or held so that they cannot easily be seen. A player’s chips must be above table-level, and larger denominations should be easily visible to all players at the table. A player who is absent from the table for 30 minutes or more will have their chips removed by a floorperson. A player’s absence may be extended with advance notice to the floorperson.
The dealer has the right to name a form of poker, and he is responsible for opening the betting in that game. He also has the right to require a player to ante more than another, but he may not force any player to ante at all. The game’s minimum and maximum bets are set by the dealer, who may not be required to accept any bet lower than his minimum and no higher than his maximum. The dealer is also responsible for setting the limits for a game, and he may not require that any player antes more than the maximum bet in the first few rounds of play.
