Poker is a card game in which players bet by raising or folding their hands. The aim is to win the pot, the sum of all bets made on a single hand. There are a large number of variations of the game. The game is mainly a game of chance, but bluffing, psychology and strategy also play important roles.

The rules of Poker can vary from one game to another, but there are certain things that all games should have in common:

A hand is dealt and betting begins with the player to the left of the dealer. There are usually a few rounds of betting before the flop, turn and river. The player with the highest-ranking poker hand wins the pot. During the betting process, the dealer must distribute any side pots among the players, and may be required to narrate his actions to prevent chip manipulation (palming).

When making decisions under uncertainty, whether in poker or elsewhere, it is essential to estimate probabilities of different outcomes and scenarios. In the case of poker, this involves considering the probability that your opponent has a better hand than you, as well as estimating how likely they are to raise on a particular street. It’s also important to know when to fold, and to have a clear reason for doing so – eg, to push out weaker hands and maximise the value of your own.
