Poker is a game that requires players to think through the consequences of their actions. It also teaches you to bet with uncertainty, which is a crucial lesson for decision making in other domains, like business or investing. The ability to bet with uncertainty is one of the biggest reasons why poker is superior to other games of skill.

The game starts with one or more forced bets, called an ante and a blind bet. The dealer shuffles the cards, and then deals each player a number of cards (either face up or down). Players can then choose to place additional bets into the pot, called raising. These bets are made when a player believes their hand has positive expected value or wants to bluff other players for strategic reasons. A player wins the pot, or total amount of money bet in the round, by having a strong hand at showdown, when all remaining players reveal their hands.

The game is played online, eliminating in-person knowledge of the other players such as physical tells, but professional poker players are experts at combining information from multiple channels, including their own intuition, to make decisions about their opponents. They can use software to build behavioral dossiers on their opponents and even collect or buy records of the other players’ “hand histories.” They are masters at extracting signal from noise and using information about their opponent’s history to make informed betting and calling decisions.
