Poker is a card game that is played by two or more players and involves betting. The goal is to win the pot, which consists of all bets placed during one deal. The pot can be won by having the highest-ranking hand, or by making a bet that no other player calls.

A poker game is normally played with a minimum of two and a maximum of seven players. The cards are dealt face down, and a round of betting takes place. The first player to act has the option of calling, raising or folding. A player can raise the amount he or she bets on each street (the preflop, the flop and the turn).

Each betting round ends when the dealer reveals the final fifth community card, known as the river. At this stage, players must reveal their hands and the player with the best hand wins.

The most common poker hands are pairs, three of a kind, four of a kind, and straights. Pairs consist of two matching cards of the same rank, three of a kind contains three cards of the same rank and two unmatched cards, and a straight consists of five consecutive cards of the same suit.

The game of poker has a large element of luck, but most professional players understand that the long-run results are determined by skill. This skill is based on a combination of probability, psychology, and game theory. If you want to become a good poker player, it is important to develop a tested and trusted strategy.
