Basic Rules of Poker
Poker is a card game in which players try to form the best possible hand of cards. There are many different variants of the game, but they all share certain important features.
A standard pack of 52 cards (sometimes with a few jokers) is used in most games. The cards are ranked from highest to lowest. They have four suits: spades, hearts, diamonds and clubs.
The rank of a hand is inversely related to its odds, that is, the higher its odds are, the lower its value is. The hand’s value is also inversely related to its mathematical frequency, that is, the more unusual it is, the higher its rank is.
Each player receives one facedown card and one faceup card. The deal is interrupted for a betting interval and then continues until the last bettor shows his hole cards.
After the cards have been dealt, players can either fold, which means not playing this round; check, which means matching their bet; or raise, which means adding more money to the betting pool.
Each betting interval begins when a player to the left makes a bet by putting into the pot the same number of chips as any preceding player. The next player to the left must call that bet by putting into the pot the number of chips required for the previous player to have called; or raise, which means adding more than enough chips to the pot to make the previous player raise.
