Poker is a game of cards played by two or more people. It is a card game that requires skill and strategy. Although the outcome of a hand significantly involves chance, the long-run expectations of players are determined by decisions chosen on the basis of probability, psychology, and game theory. The goal of the game is to win money by making bets that have positive expected value or by bluffing other players for strategic reasons.

When a player has the best hand, they win the pot. This is called a straight or a flush. A straight consists of five consecutive cards of the same suit, such as spades, hearts, diamonds, and clubs (from highest to lowest). A flush consists of three matching cards of one rank and two unmatched cards of another rank.

In addition, you must be able to read body language to see whether your opponents are lying or bluffing. Finally, you must be able to make smart calls and fold when necessary.
