Poker is a card game that requires players to make decisions on the basis of probability, psychology, and game theory. While the outcome of any hand significantly involves chance, it is not impossible to win at a high level by employing a well-defined strategy.

The best poker strategy includes an understanding of the basic rules, the ability to recognize different types of betting patterns, and a strong sense of poker etiquette. Beginner players often lose, while more experienced players frequently become winners.

Basic rules

Poker begins with a player or group of players making some form of forced bet, usually called the ante or blind. The action then proceeds clockwise, with the last player to bet either matching (or “calling”) the previous bettor’s bet or raising his own, or else folding and thereby losing all of his money.

In some variants, the ante is not a fixed amount and can be raised at any time before the first betting round ends. Once all of the bets have been placed, there is a showdown, in which the players reveal their cards and evaluate their hands.

Winning hand identifiers

The highest possible hand is the royal flush, which contains ace, king, queen, Jack, and ten, all of one suit. If two or more players have this hand, a high card breaks ties.

Pair, flush, straight, and full house are other winning poker hands. A pair is made up of two cards of the same rank and two cards of another rank; a flush is a set of five consecutive cards, all from the same suit; straights are a sequence of five cards, not necessarily in sequence, from any suit, except clubs; and full houses are a set of three matching cards of one rank, plus another pair or three unmatched cards.
