The Basics of Poker

Poker is a card game played by two or more players. The aim is to win the pot, which consists of all bets made during the course of a deal. While the outcome of any individual hand largely involves chance, in the long run it is determined by a player’s actions chosen on the basis of probability, psychology and game theory. Money is placed into the pot only when a player believes it has a positive expected value or is trying to bluff other players for various strategic reasons. A player may also “drop,” meaning that he puts no chips into the pot or discards his hand, and thus relinquishes any rights to the original or side pots.

A round of betting begins after each player has received two hole cards. Depending on the rules of the game, one or more players may place an initial amount into the pot before the cards are dealt, which are called forced bets and come in the form of antes and blinds.

After the flop is revealed, a further round of betting takes place. After this the dealer reveals one more card, which is called the river. Then there is a final round of betting and the player with the highest-ranking hand wins the pot. Players may also exchange their own cards for replacements after the flop, but before the river. This is known as a “showdown.” During a showdown, each remaining player shows their cards face up and must then make a decision to raise or drop.
