The game of poker is played by a group of players around a table. Before the deal, each player is given a card from a shuffled pack, and whoever receives the highest card becomes the first dealer. After that, each player takes turns betting into the pot (the pool of money in the center of the table). The best hand according to the rules of the poker variant being played wins the pot.
A poker hand is made up of five cards, and the value of a card in a particular hand depends on its mathematical frequency (i.e., its probability of appearing). The value of a card can also be enhanced or diminished by the presence or absence of other cards in the same hand. Players may also bluff, in which case they make bets that they do not have the best possible hand, hoping to induce calls from other players with superior hands.
In most poker games, players must place a small bet (the amount varies by game) before being dealt cards. Once the betting is over, the players reveal their cards and evaluate them. The player with the best hand wins the pot. The most common hand is a pair of two identical cards. The highest pair is the Ace, King, Queen, Jack, and Ten of the same suit. Another popular hand is the straight, which is a running sequence of cards of any suit.
