Poker is a card game that can be played by two or more players. It is played in casinos, private homes, card clubs, and on the Internet. It has become an international sport with its own World Series of Poker, and its play and jargon have spread into popular culture. It is considered a mind game and has been called the national card game of America.

Poker combines strategy, mathematics, and luck to produce a game of skill for its players. The goal is to win the “pot,” the total of bets made in a betting interval. A player may choose to check, call, or raise. In fixed-limit games a player may not raise his bet more than twice the amount of the previous bet.

Unlike many other card games, suits have no rank in poker, and identical hands tie and divide any winnings equally. The highest hand is five of a kind (any four cards of the same rank, plus a pair). Other high hands include three of a kind, straight, and flush. Ties are broken by the highest unmatched cards or secondary pairs (a full house consisting of three of a kind and a pair, or two pair).

The best poker players use a combination of raw technical skill and luck to maximize their edge in the long run. They learn to identify optimal frequencies & hand ranges, and use that information to make the best decisions at the table no matter what situation they find themselves in.
