Poker is a card game in which players bet on the strength of their hand. The player with the highest ranked hand wins the pot, which is all of the money that has been bet during the hand. If no one has a high ranked hand, the dealer wins the pot.

A standard deck of 52 cards (some variant games use multiple packs or add jokers) is used to play poker. There are four suits (spades, hearts, diamonds and clubs) and each suit has a different rank. The ace is the highest rank, followed by the king, queen and jack.

There are also various types of poker hands, each with its own probability of winning. The most common hand is a pair. A pair is two matching cards of the same rank, such as a pair of kings or a pair of fives. A flush is a sequence of 5 cards of the same rank, which can be in consecutive order or in a straight. A full house is three matching cards of one rank and two matching cards of another rank, such as a pair of jacks or a trio of queens. A straight is five consecutive cards of the same suit, such as a 5-3-2. A single card, known as a hole or community card, can be added to any poker hand to improve its value.

When a round of betting is over, the players reveal their cards and decide whether to stay in or fold their hand. If they remain in the hand, they bet again on the chance that their hand will be the best. The player who has the highest ranked hand when all of the other players have folded wins the pot.

During each betting round, the players can choose to call, raise or check. When a player calls, they place their chips into the pot equal to the amount raised by the last player. Raising is the same as calling except that a player raises by an amount greater than the previous bet.

After the second betting round, a third community card is dealt face up. There is a new round of betting, starting with the player to the left of the dealer. The fourth and final betting round, called the river, reveals the fifth and final community card.

While poker involves a certain degree of chance, the long-term expectation of a player is determined by the actions they take, which are chosen on the basis of probability, psychology and game theory.
