The Basics of Poker

Poker is a card game in which players wager money on the outcome of a hand. It is a game of chance, but the long-run expected value of the players’ decisions are determined by factors such as probability, psychology, and game theory. Players may choose to bluff, believing that their hand is superior to the other players’, or they may fold when they know that their hand is weak.

A poker dealer is responsible for shuffling the deck and dealing cards to each player in a round of poker. This person is usually a player, but in some cases it can be a non-player who has been given dealer responsibilities for an entire round or multiple rounds. A dealer chip is used to designate the dealer, and this chip is passed on to a different player after each round of betting.

Players must place an amount of money into the pot (representing money, for which poker is almost invariably played) at least once during each betting interval according to the rules of the particular poker variant being played. This amount is called an ante or blind bet.

After all players have revealed their hands, the winner is declared based on the best poker hand. The highest-ranked hand consists of five distinct cards of the same suit, or one pair with two distinct cards and a high card. If there is a tie for the highest hand, then the highest card breaks the tie.
