There are a number of different ways to win at poker, including bluffing, stealing bets, and raising with the best possible hands.

Despite the fact that the outcome of any particular hand in poker is heavily dependent on chance, a skillful player can improve his chances of winning by using a combination of probability, psychology and game theory.

A high poker hand consists of any five cards of consecutive rank, while a straight contains five cards that skip around in rank or sequence and a flush contains five cards of the same suit. The high card breaks ties.

A poker game usually starts with a forced bet, called an ante. The player to the left of the dealer places the ante and then players can bet on their hands. After the betting rounds are over, players must show their hands and the winner is determined. Often times there are side pots, with the winner being determined by who placed the bet that caused other players to drop out of the original pot.
