Poker is a card game that involves betting and is played by two or more players. It is considered a game of chance, but the long-run expectations of players are determined by actions chosen on the basis of probability, psychology, and game theory. A player’s decision to call, raise, or fold is based on the perceived value of his or her hand, as well as the expected behavior of other players.

There are typically one or more betting intervals in a poker deal, depending on the rules of the particular game. During the first of these betting intervals, each player must place into the pot (representing money) an amount equal to or higher than the amount placed in by the player before him. Then, the dealer will shuffle and deal each player 2 cards face up. This is known as the flop.

Then there is another round of betting, with the player to the left of the dealer opening the betting. After this, the dealer will reshuffle and draw replacement cards for those in the discard stack.

A player’s best 5 card poker hand is made up of his or her two personal cards in the hand and the five community cards on the table. The highest ranking poker hands win the pot. If two hands have the same rank, the hand with the higher card outside (a pair, three of a kind, straight, or flush) wins. Ties are broken following the rules of High Card.
