Poker is a card game in which players bet into the pot during each round, raising and re-raising as they see fit. The highest hand wins the pot. While Poker is primarily a game of chance, good players make decisions based on probability and psychology to call or fold their hands in ways that maximize long-term profit.

To begin each round of betting, two mandatory bets called blinds are placed into the pot by the players to the left of the dealer. Once everyone has received their 2 hole cards, a second round of betting begins.

The poker game is usually played with a standard 52 card pack (although some games use multiple packs or add one or two jokers). The cards are ranked from high to low: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, and 3. The game may also specify wild cards (dueces, one-eyed jacks, etc).

Once all players have raised their stakes in the pot once, the dealer deals each player a complete hand of five cards. Once the hand is dealt, players begin betting in clockwise order. Players may ‘check’ (pass on their turn to raise), call a bet or raise it themselves.

A player wishing to stay in the pot must match the total stake made by the last player and may further raise it. If he is unwilling to do either, he must fold. This equalization method is the basis for all modern vying games, including Brag (17th – 18th centuries), Bouillotte (19th century) and Poker.
