Poker is a game where you have to make bets with chips or cash. You can call, raise or fold when it is your turn. The object of the game is to win the pot, which is the sum of all the bets made by players in a single deal. You can win the pot by holding the best possible hand, or by making a bet that no other player calls.
Professional poker players are experts at extracting signal from noise and integrating information from many channels to both exploit and protect themselves against opponents. They do this using a combination of in-person cues and behavioral dossiers, which they build by studying the actions of other players. They also use software to track the history of other players’ hands and to identify tells.
This approach allows them to gain a competitive edge by understanding their opponent’s range of hands and working out how likely it is that their own hand will beat their opponent’s. This is known as putting an opponent on a range and can be done by observing an opponent’s betting patterns.
