How to Bluff in Poker



Poker is a card game in which players bet on the strength of their hands. A hand consists of five cards (or seven for some games). Each player assesses the value of their hand relative to that of other players, and then wagers chips in a betting round. It is possible to win a pot without having the best hand, by bluffing. To be effective, a bluff must be made with confidence and at a frequency that makes opponents suspect it is genuine. In a simplified experiment, von Neumann demonstrated that, with the right mix of bet sizes and frequencies, it is possible for skilled players to make a profit in long runs.

To play poker, each player must first place an ante to the pot, which is usually twice as large as the small blind. A player may then choose to call the previous bet or raise it, and must continue to act in turn until they have all folded. If a player chooses to fold, they forfeit the chips bet so far and any further involvement in the hand.

When betting, players can use “tells” to help identify whether an opponent is bluffing. These include shallow breathing, sighing, nostril flaring, blinking rapidly, and an increasing pulse in the neck or temple. The most common tell is staring down the opponent, but a player can also look nervous or anxious by placing a hand over his mouth or shaking it.
