Poker is a card game in which players wager chips (representing money) against other players and the dealer. It is a game of chance, but skill can minimize losses with weak hands and maximize winnings with strong ones. The game is played in many forms from two to 14 players, but most games are limited to six or eight players. The object of the game is to win the pot, the sum of all bets made during one deal. Players may call a bet (match it), raise it, or drop it. The player who has the best poker hand wins the pot. Players may also bluff, betting that they have a superior hand when in fact they do not.
A poker hand consists of five cards, with each player holding two personal cards in their hand and a shared community card in the center of the table. The value of a poker hand is in inverse proportion to its mathematical frequency; thus, rarer combinations rank higher. The highest rank of poker hand is a pair of aces, followed by three of a kind and then straight. In some variants, wild cards can be used to make up poker hands.
The rules of a poker game may require each player to place an initial contribution, called the ante, into the pot before the cards are dealt. After the ante is placed, the dealer will begin dealing the cards one at a time, face up, until he deals a jack. At the end of a betting interval, the dealer will reveal a fifth community card, called the river. After the river, players will either show their hands or fold.
