Poker is a card game of strategy, skill, and chance. It can be played in a casual setting for pennies or matchsticks, or professionally in the world’s most famous casinos for thousands of dollars. There is a huge amount of luck involved in the outcome of a poker hand, but the game also requires a great deal of specialized knowledge of probability, psychology, and games theory.
Players make betting intervals (called “rounds”) by putting chips into the pot. Each player must either “call” that bet by putting the same number of chips into the pot as the player to their left, or “raise” by putting more than the minimum amount into the pot. A player may also “drop” (fold), in which case they forfeit the chips that they have already put into the pot.
The economics of a poker hand are analyzed in terms of “equity,” which is the percentage of the pot that a player would have if all the players bluffed equally and the rules were fixed. Although equity does not address the specifics of a particular hand, it is useful for comparing players’ play styles. For example, a higher degree of tightness is often viewed as an indicator of improved play.
In addition to the money that each player puts into the pot, a special fund is usually established called the “kitty.” This fund is used to pay for new decks of cards or for food and drinks. At the end of a poker game, any chips that were part of the kitty are divided equally among the players who remain in the game.
