Poker is a card game that has been played worldwide for over a century. It is a popular game played in casinos, private homes and on the Internet. It is a game of skill, which means that players who follow a sound strategy win over the long run.
There are many different variants of poker, each with its own rules and specific betting intervals, but the basics remain the same. In most games, each player is dealt a hand of five cards facedown and one faceup. The cards are then used to make the best possible poker hand, which is then compared with the cards of each other player. The best hand wins the pot, and if two or more hands have the same hand the prize is split evenly.
In draw poker each player’s entire hand is concealed until the showdown; in stud poker some but not all of a player’s cards are exposed and used to form his best hand; and in community-card poker some cards are exposed for use by all players.
All players are required to post small and big blinds before a hand is dealt; these blinds require players to contribute money or chips before the deal begins. The blinds ensure that there is action on every hand, so that the game doesn’t become boring.
An ante is a forced bet that all players are required to pay before the hand commences, giving the pot a value right off the bat and encouraging players to play their hands rather than to fold before the hand starts. The ante usually involves a single unit, but can be a proportion such as a half or quarter of the minimum bet.
A player may call the bet, which matches it or folds, in which case he doesn’t make any further contributions to the pot. He can also raise the bet, which increases it by more than what he originally paid.
When all active players have made a bet, the round ends. If a player folds before the end of the round, he can’t be called in any subsequent betting interval; the opponent who bet before him is in effect a winner of that pot.
If a player calls, he adds his bet to the existing bet of the person in front of him. If he folds, he withdraws his bet and loses all his chips in the pot.
In most games, the lowest-ranking poker hand is 7-5-4-3-2 in two or more suits; however, in some variations such as Omaha a player may have two different low hands, for example 6-4-3-2-A. The highest-ranking hand is a straight, which consists of five consecutive cards in the same suit.
The nut flush is a pair of aces and a single card of a different suit, such as a 7-6-6. It is the best possible hand in any poker game, regardless of the suit.
