Often called the national card game of the United States, poker is a card game played with a deck of cards. It is usually played with chips, and can be played by any number of players. The objective of the game is to make the best hand possible.
Depending on the variant, each player may use one, two, or three cards from their hand, and may also bet on the hand. If a player bets, other players must also match the bet. If no other players are willing to match the bet, the pot is won.
Poker is played in clubs, casinos, private homes, and online. The earliest version of the game in Europe is probably the 17th-century French game poque. It evolved along with the German game pochen and the Spanish primero. It spread to the New World with French settlers.
The first betting interval occurs after a round of dealing. The dealer deals the first three community cards face up. The remaining players receive one downturned card and one upturned card.
In this round of betting, the player to the left of the big blind is first to act. He may check or raise the bet.
If the player to the left of the big blind does not raise the bet, the player to his left declines to fold and the player to his left may do so.
The betting interval is then repeated. This process occurs three times, with the fourth and final betting interval occurring after the dealer has shuffled the cards. The player with the best hand wins the pot.
