Poker is a card game played by two or more players. In the most basic form, each player is dealt five cards. After a round of betting, the best hand wins. Some games allow players to discard cards and take new ones from the deck, while others use wild cards (usually jokers) to determine the winning hand.
The card values are the same as in standard decks of playing cards: Ace, King, Queen, Jack, 10, 5, 4, 3, 2 and 1. In addition to the rank of each card, some games differentiate between suits; for example, a straight might not wrap around (A-K-Q-J-T), and a flush might not include an ace (A-K-Q-J-4-3) or a four of a kind (A-K-Q-J-8-3).
It is important to study and memorize poker rules before playing, but more important to learn the quick instincts required to read the opponents. Watch experienced players and try to figure out how they play to develop these instincts.
Generally, each player must put into the pot at least as many chips as the player to his or her left. Players may call, raise, or drop out of the betting round. When a player drops out, he or she forfeits any chips that have been deposited into the pot and discards his or her cards.
Often, when a player has a weak or marginal hand, he or she will fold, rather than risk losing even more money by continuing to bet on it. This is a good strategy, as it keeps the pot value high and forces stronger hands out of the game.
