Poker is a card game in which players compete for an amount of money or chips contributed by each player to a central pot. Each player places the amount of his bet in the pot according to the rules of the particular poker variant being played. Players place their bets in the pot by either raising or calling. They also make decisions about the value of their own hand and the probability that other players have a particular hand.
Poker has a reputation for being a game of luck. Players often complain about bad luck or rotten cards and agonize over missing flops or getting sucked out on. The reality is that poker, like most other activities, involves taking risks for possible ultimate reward and the luck factor diminishes as the number of hands played increases.
Players play poker with chips that are usually colored (red, black, green, or blue) and assigned a value prior to the start of the game. Cash games are typically fast-paced, and players bet in their turn by placing their chips into the pot. A player may also check during a betting round if he does not wish to raise the bet. However, if another player raises, the player must call or fold. The player with the highest hand wins the pot. The highest hand is a Straight, which contains five consecutive cards of one suit; a Flush includes three or more matching cards of the same rank and two unmatched cards; a Three of a Kind is made up of 3 matching cards of the same rank; and a Pair is 2 matching cards of different ranks.
