Poker is a game of chance in which players bet on the outcome of a hand of cards. The player with the best hand wins the pot, which is a sum of all bets made by all players in a single deal. The winnings are usually divided equally among the players.
Poker has a number of variations, each of which is played with different rules. However, most versions of poker share certain common features.
The basic goal of any poker game is to have the highest-ranking hand of five cards. A poker hand is ranked in inverse proportion to its mathematical frequency; the more unusual the combination, the higher its rank.
Standard poker hands consist of two or more cards of the same rank, called a “high card,” and two or more cards of different rank, called a “pair.” Pairs can be of any rank; in addition to high cards, the most common pairs are two sixes, two sevens, and two nines.
Other common hands include three of a kind, four of a kind, five of a kind, and straight. A straight is made up of five cards in sequential order, while a flush is made up of five cards of the same suit, but not in sequence.
A poker game typically begins with a bet called the blind or ante. This is the first bet by a player and serves as a signal that he is ready to play. Unlike some other games, such as Pinochle, Poker is played clockwise around the table, with each player putting in a bet after the previous player.
