Poker is a family of card games in which players bet over which hand they believe is best. It is played in private homes, casinos, and on the Internet.
Rules vary among games, but the basic structure is the same. A complete hand is dealt to each player, and a round of betting takes place.
Each round of betting may be repeated, with each bettor able to raise or call (match) the previous bet. The betting round ends when all players have either called or folded their hand.
The game begins with one or more players posting forced bets called blinds, which are small and big bets that all the players have to make before the cards are dealt. These are required to give the pot a value right off the bat and ensure that there will be some level of ‘action’ on every hand.
After the cards are dealt, each player is dealt a complete hand of five cards. The player who has the highest hand wins the pot.
In pot-limit games, a player may not bet or raise more than the amount in the pot at the time of the bet or raise. The bet or raise is then matched by the next player in the betting round, who can then bet or raise more than the original bet or raise.
In a poker game, a player who does not want to compete for the pot must drop or fold his hand by placing it face down on the table and losing whatever he has bet so far. This is usually done when a player thinks that his hand is too weak to compete for the pot against other players.
