Poker is a card game played in casinos and private homes around the world. It has many variations. There are high-low games, low-high games, stud poker and more. However, the basic rules remain the same.
Cards are dealt in a round, face up, and then each player is given a turn to bet. During a betting interval, players may check or raise. If a raise occurs, the player must call or fold.
If no one calls the bet, the pot is won. Players can also win the pot by bluffing or betting the best hand. In some versions of the game, the pot is split between the highest and lowest hands.
The first player to make a bet is known as the bettor. The other players must either match or raise the bet.
The dealer is the one who shuffles and deals the cards. Typically, two decks of different back colours are used. Before the game begins, the dealer assigns values to the chips.
Each player is dealt five cards. A pair is formed when two of the same cards are dealt, and a straight is a combination of three cards of the same suit. Two pairs, one pair and two singles are considered a hand.
One of the major differences between poker and other card games is that the value of a poker hand is determined by a mathematical frequency. For example, a pair of aces beats a straight flush.
