Poker is a card game in which players independently try to assemble the highest value combination of cards. It is played in casinos, card clubs, private homes, and over the Internet, and is considered the national card game of the United States. It has been described as the game of cards that has come to define American culture, and its play and jargon have spread worldwide.
The rules of Poker differ slightly from one variant to the next, but the basic procedure is always the same: players must either call (match) a bet, raise it, or fold. The amount of money a player puts into the pot during a betting interval is called the ante. A player may also push all of his chips into the pot in a single move called an all-in.
A standard 52-card pack is used in Poker, and the deck is shuffled before each deal. Often two packs of contrasting colors are utilized to speed up the dealing process, and the cards are passed from the previous dealer to the next.
When a player has decided to stay in the hand, he must place in the pot a number of chips (representing money, for which poker is usually played) equal to or greater than the total contribution made by the player sitting on his left. This is called being in the pot. During each betting round the cards are dealt, and at the end of all the betting, the hands are revealed.
Usually, the best Poker hand wins the pot; however, there are a few exceptions. In some cases, a pair of identical high cards will tie; in this case, the kicker determines who wins. In other cases, ties are broken by the highest unmatched card or secondary pairs (in a full house, for example).
In some games, there is a kitty, which contains the low-denomination chips that players have contributed to the pot. This is an important aspect of the game, as it allows players to contribute to the cost of food and drinks, new decks of cards, and other items necessary for a successful game. When a player leaves the table before the game has finished, he is not entitled to take any of his share of the kitty with him.
In most poker games, players must bet to remain in the hand. If a player does not want to call or raise a bet, he can choose to check. This is permitted only if no player has raised a bet before him during the betting interval. If he checks, he must either call or fold the following bet. Alternatively, he can raise the bet himself. This is called sandbagging, and it is an effective way to bolster the strength of weak hands. However, it is not recommended to use this method for long, as it can be a waste of time and resources for the entire poker game. When a player wishes to raise the bet again, he must match the stake of the last raiser.
