What is Poker?

Poker is a card game in which players wager money on the outcome of a hand. The game has hundreds of variations, but most share a common framework. At the start of a round, one or more players make forced bets, called “antes” and “blinds.” The dealer then shuffles the cards and deals each player two cards face up (or, in some games, face down). Depending on the game, the cards may be revealed during multiple betting rounds, with bets collected into a central pot. The game offers many mechanisms for players to misinform their opponents about the strength of their hands, such as revealing a small number of cards in the early rounds to signal weakness, or making large bets before “showdown,” when all remaining players reveal their cards and the player with the best five-card poker hand wins the pot.

In both poker and life, you must weight risk against reward. Playing it safe means missing out on opportunities to take a chance and potentially win big. It also means bluffing less frequently, which can be exploited by an opponent who knows that you are unlikely to call their bets unless they have a good hand.

Historically, poker has been a game of intuitive feel and experience. In recent times, however, the game has evolved into a form of detached quantitative analysis. Professional poker players use models to calculate the probabilities of their opponents’ actions, and they hone their strategies by running thousands of simulations.
