Poker is a card game in which players compete for an amount of money or chips contributed by the other players (called the pot). Each player tries to predict what cards their opponents may hold, and how they might behave. Players then make bets based on these predictions. A player who has the best hand wins. Players also try to force other players to fold by bluffing.
A hand consists of two personal cards in your hand plus five community cards on the table. You can win by making a pair, three of a kind, four of a kind, a flush, or a straight. A straight is five consecutive cards of the same suit, such as 3 hearts and 2 diamonds. Three of a kind is three cards of the same rank, and a pair is two matching cards of any rank.
In the game of poker, players wager against each other for an amount of money or chips contributed by themselves and other players (called the pot). The dealer is responsible for shuffling the deck and dealing each player a set number of cards. The dealer is usually a non-player, but occasionally a player takes on this role. A dealer chip is passed around to indicate who is the dealer for each round.
Expert players use sophisticated models to analyze their opponents and make bets. This has transformed the game from an intuitive game of feel to a detached quantitative analysis.
