Poker is a card game that is played for money. It is a game of skill, but also has elements of chance. Players play against each other and the dealer, and the goal is to get the best hand possible.
The first player to act (the “dealer”) deals five cards face-down, and begins a betting interval, which is followed by a showdown. Alternatively, the dealer can deal two packs of cards, or draw cards from the top of the deck and replace those in the hand.
One or more jokers are sometimes added to the standard pack, and players may use them in place of any other card. This practice is particularly common in stud poker and Canasta games.
Typically, the player to the left of the dealer, referred to as the small blind, pays the ante and is seated in the first-to-act position. This position is to the immediate left of the big blind and pre-flop, to the left of the button for subsequent betting rounds.
A betting round follows each dealer’s deal, with each player putting in the amount of his ante. The player then may call a raise from the person to his right, increase his ante, or fold.
The pot, or sum of the bets, is won by the player with the highest-ranking poker hand, and/or by making a bet that no other player calls. This decision is made on the basis of probability, psychology, and game theory.
