Poker is a card game where players place bets on the probability that their cards are better than those of their opponents. The game is popular for its social aspect and the ability to win big money with bluffing. A game of Poker usually consists of a series of betting rounds, with each player having the opportunity to raise or fold. The game is played with a minimum of two players and a maximum of seven.

A professional poker player is a master at extracting signal from noise across multiple channels, including eye contact and body language. They are adept at integrating this information into their decision making process, both to exploit their opponents and to protect themselves. Online poker eliminates in-person knowledge of players, but the best players compensate for this by analyzing data on past play and building behavioral dossiers of their opponents.

The game has many variations, but all involve a centralized pot, a sequence of betting phases and a showdown phase where players reveal their hands. Each hand starts with a forced bet, usually an ante or blind bet, made by players to the left of the dealer. Once the players have committed their resources, a set of 5 cards are dealt to each player. The player’s hidden cards are called their hole or pocket cards.

After each round of betting, another set of 3 cards are revealed at the center of the table. These are called the flop and they are community cards that can be used by all players to form their 5-card poker hands.
