Poker is a card game with many variations. Four-card hold’em, for instance, is a variant of the game that requires players to use two hole cards and three board cards. The goal of this game is to have a pair of cards that is larger than a community card on the board. In each round, a player at the table passes the dealer button to the other players in the table, who are then dealt their cards.

In casual play, the right to deal a hand rotates among the players in a clockwise rotation. The dealer button, also known as the “buck”, is a white plastic disk that indicates the nominal dealer. A player must bet at least the required minimum in the first betting interval to get the right to bet. In later betting intervals, the player may check.

In the event that no one wins the pot, a player can bet an all-in bet. This bet, which is often the last option, requires the player to place all of his chips in the pot. Depending on the type of poker, the all-in bet has special rules. When all of the players in the game have checked, folded, or called, the round of betting ends.

In a standard poker game, a player must ante before playing. This amount varies from game to game. Players then make a bet in the middle of the table, called the pot. The winner of the pot is the player with the best hand. Betting occurs in a clockwise fashion.
