Poker is a card game that involves betting and requires a certain level of skill, probability, and psychology. In the early stages of the game, players must ante (a small amount, typically a nickel) to receive cards; this money is put into a central pot. Once the cards are dealt, betting begins; each player may choose to call (match the last bet made), raise (adjust the amount of his bet), or fold.
Once the betting is over, a showdown occurs in which each player shows his hand. The best hand wins the money in the pot. If there are multiple best hands, the pot is shared among the players with those hands. Some players will also bluff, raising their bets in hopes of convincing others that they have a good hand.
The highest possible hand is a royal flush, which contains a King, Queen, Jack, and Ace of the same suit. A straight is five consecutive cards of the same suit, such as 5-6-7-8-9. A full house is three matching cards of one rank and two matching cards of another rank, while a pair is four matching cards of the same rank.
To start the next round, the dealer shuffles the cards again and deals them to each player in rotation, starting with the player to his left. In many games, the first player to the left has the right to cut. A player may also volunteer to shuffle and deal, in which case he becomes the dealer for that round.
