Poker is a card game in which each player places a bet before the dealer deals 2 cards to each. There are then one or more betting rounds, depending on the game. In each round players reveal their hands and the highest hand wins the pot. There are a number of different rules and variations to poker but the most important thing is to know when to call and when to raise.

The game of poker is based on chance but the outcome of any particular hand depends to a large degree on player choices made based on probability, psychology and game theory. There is no compulsion to place any money into the pot and any bet is made only if a player believes it has positive expected value. However, players will usually bet more often and aggressively when they have a good hand, especially if they are first to act in the betting round.
