Poker is a card game in which players try to make the best five-card hand from a standard deck of cards. There are several variants of the game, but they all share a few important characteristics.
The basic rules of poker involve the deal of cards, a round of betting, and the reveal of the hand. The player who holds the highest hand wins the pot.
A standard poker hand consists of five cards, ranked from high to low. The highest possible hand is five of a kind, which beats any straight flush.
All standard poker hands are ranked on the basis of mathematical probability; the higher the rank, the more likely it is that someone will hold a particular combination of cards. Ties are broken by the highest single card, if no combination is possible.
The game of poker is played by a number of people around a table, each holding their own stack of chips. Each round of betting lasts until one person has all their chips or everyone folds.
Betting rounds can be made during each of the seven cards that are dealt to each hand, or in a sequence, as determined by the rules of the game. The player who makes the first bet in any betting interval is called the “dealer,” and must make another bet after each card is revealed to each hand.
A player may choose not to make a bet in any betting interval, and instead may check (in effect, making a bet of nothing). A check can only be made when no one else in that interval has made a bet.
