Poker is a game in which players try to make the best possible poker hand using only the cards in their hands. It is a popular gambling game with a history that extends back to the Renaissance and bluffing (the practice of making up a hand in order to win) has long been a part of the game.

A basic strategy for winning a hand of poker involves betting with the correct frequency and hand ranges. The best poker players are able to make optimal betting decisions with their hands in all situations, regardless of the odds being against them.

The main forms of Poker are Draw Poker and Stud Poker. Both involve a deck of cards, which is dealt face down to each player and then some of the cards are dealt face up as the betting progresses.

Dealing of the cards: In most games, a dedicated dealer deals one card to each player. The dealer may be a house dealer, or another player.

Betting intervals: The first bettor in each betting interval must make a bet at least the minimum established. He can choose to call the bet, raise it, or check.

Rank of standard poker hands: The highest hand wins the pot. A straight is the best hand, followed by a flush and four-of-a-kind. Tied hands are split equally.

The flop: Each player receives two facedown cards and one faceup card; the player to his left in the hand is the first to act by folding, calling, or raising.
