Poker is a card game where players place bets, called chips, into a central pot, with the goal of making the best five-card hand. There is significant luck involved in the outcome of individual hands, but the long-run expectations of players are determined by their decisions chosen on the basis of probability, psychology, and game theory.
A dealer shuffles the cards, then deals two cards to each player, face down (except in some games where one or more of the players are dealt a full set). The first bet is placed by the player on the chair immediately to the left of the dealer, called the button. Each subsequent player must either call the bet or raise it. The raised amount is known as the ante. The betting continues in a series of rounds until all players have shown their cards.
Some poker variants allow players to exchange their cards for replacement cards during or just after the betting round, while other games require that a player discard his whole hand and start over again. The player who has the highest-ranked poker hand when all players have discarded their hands wins the pot, which contains all of the money bet during that particular round.
