Poker is a card game played between two or more players and involves betting in some fashion. The game has many variants, but all share some basic rules. In standard poker a player must either call (match or increase) the highest bet made by any other player in order to remain involved in the hand, or fold, giving up the amount of money bet so far and any chance to win.

A poker hand consists of five cards. The value of a poker hand is in inverse proportion to its mathematical frequency; the more rare the combination, the higher the hand’s rank. The most common poker hands include one pair, two pairs, three of a kind, four of a kind, straight, and flush. Ties are broken by the highest unmatched cards, or secondary pairs (in a full house).

Each player begins a betting round with some form of forced bet, usually a blind or an ante. The dealer shuffles the cards and deals them to each player in turn, beginning with the player on his or her right.

If the player has a high hand, he or she bets to encourage other players to continue betting and possibly improve their own hand. This is called bluffing, and it can be very effective at increasing your winnings. The more you play, the better your instincts will become; learn to read your opponents’ reactions and you can make good decisions faster.
