Poker is a card game played between two or more players and involves betting. It can also involve bluffing. The object of the game is to make a hand with five cards that ranks higher than those of your opponents, and you win if you have the best hand. Poker is played in casinos and private games. It has gained worldwide popularity, and it is a major source of income for professional players.
The game starts with an ante or blind bet, which must be made before the dealer shuffles and deals the cards. The player to his right cuts the deck, and then the initial dealer begins dealing cards. Each round is followed by one or more betting intervals, with the players’ hands developing between rounds. After the final betting round, all players reveal their hands and the player with the highest ranking hand wins.
During each betting interval, a player may choose to make a bet, or “open,” by placing chips in the pot equal to the amount of money placed there by the player before him. He may also say, “I call,” to match the previous bet and place the same amount of chips or cash in the pot.
A player who does not call a bet is said to have folded his hand. He cannot raise his bet later, but he may increase his own previous bet or place new chips into the pot. He may also pass on his turn, but must remain active in the pot by either calling or folding his hand at the end of a betting interval.
