Poker is a card game with a long history and diverse traditions. Despite its prevalence in popular culture, it is not simply a game of chance: it has significant roots in probability theory, psychology, and decision making. Professional poker players develop meta-skills that allow them to cultivate and protect their sources of relative advantage in the game.

Players place bets into a central pot by calling, raising, or folding. Once each player has revealed their cards, the betting round ends. The player who has the highest hand wins the pot.

The first step to understanding how to play poker is knowing the basic rules. Then you can make more informed decisions when playing poker online and in person. Learn how to read other players’ behavior and watch for tells. These aren’t just cues like fidgeting or wearing a suit, but how a player plays the game—whether they flinch at a big raise or bluff.

You can find many resources for learning poker strategy and tactics. One of the best is Maria Konnikova’s book The Biggest Bluff. She’s a super smart, PhD-level psychologist who learned to play poker as a way to understand uncertainty and the role of luck in life. Her book is both a memoir and meditation on the role of luck in our lives. It’s a must-read.
