The game of poker is a card game in which players place chips into a pot voluntarily for strategic reasons. While the outcome of any individual hand largely involves chance, long-run expectations are determined by the actions chosen by each player on the basis of probability, psychology and game theory.

There are 52 cards in a standard deck, divided into four suits of 13 ranks each. The cards have equal value and no suit is higher than any other. The highest ranking hand is the royal flush, which consists of a 10, Jack, Queen, King and Ace of the same suit in sequence (clubs, diamonds, hearts or spades). A straight is 5 consecutive cards of the same suit. A full house is three cards of one rank and two matching cards of another, while a pair is 2 cards of the same rank plus two unmatched cards.

New players tend to get tunnel vision and focus solely on their own hand when playing poker. This is a mistake because you also need to think about what your opponent might have in his hand.

A common mistake is calling every time someone else raises the stakes when you have a mediocre hand. This is usually a bad idea because your opponents will know that you have trash in your hand and they will be much more likely to fold to your bluffs on the turn and river. Instead, you should always bet when other players check/limp and hope that you can make a good hand on the flop.
