Poker is a card game in which players compete to win the pot, or the sum of bets placed during a hand. The game has many different variants but all share some core principles.
In most forms of the game there are six to eight players and the object is to have the highest-ranking poker hand at the end of a betting round. Players may also bluff in an attempt to win the pot without having the best hand.
Each player is dealt five cards. A poker hand consists of any combination of five cards that ranks higher than the other hands. If more than one player has the same hand, then the one with the highest card wins.
There are two suits, spades, hearts and diamonds; the higher the rank of a card the more valuable it is. The Ace is the highest card and can make or break a hand. In most games, the highest pair beats a high two-pair and so on. Some games use wild cards or jokers to change the value of a hand.
A betting round begins when the first player, in turn, places chips into the pot. Each player to his left must either call the amount of chips being put into the pot, raise it or fold. If a player declines to call the amount being raised he must discard his hand and is said to “drop.”
After a betting round ends the dealer deals three more cards face up on the table, known as the flop. These are community cards that everyone can use. The flop can change the strength of your hand so it is important to pay attention to what other players do.
Once the flop is revealed the third betting round begins. In this round the players will usually check, call or raise. A player with a strong hand may want to raise in an attempt to scare off other players.
As a general rule of thumb, your bet should never be less than half the size of the pot. However, the standard for amateur players is to bet between three-quarters and full pot size. Your position at the table is also an important factor. Late positions allow you to play a broader range of hands and can help you protect your hand from aggression from early position players. On later betting streets, you should always try to avoid calling re-raises with weak hands. This will often lead to bad results.
