Poker is a card game in which players wager money (or chips) on the outcome of a hand according to the rules of the particular game. The cards in a poker hand are either shared or private, and the object of the game is to win the pot – the sum of all bets made during a single deal. A player wins the pot by having a high-ranking poker hand or by betting so much that no other players call his bet.

There are many different forms of poker and the number of cards in play varies from 2 to 14. But all the variants have at least one thing in common: betting rounds.

During the first betting round, each player must place in the pot the amount of money equivalent to the blind bet plus any other bets made by players before him. This is called the ante.

A player may raise his bet by putting additional money in the pot, or he can fold. He may also bluff by making a bet that the other players think is too high and thus try to force them into folding their cards.

It is important to pay attention to the other players and read them. A good way to do this is by watching the subtle physical poker tells that they have. For example, if a player bets all the time it is likely that they are playing weak hands and can be easily bluffed. Similarly, if a player doesn’t bet he may be holding strong cards like pocket kings or queens.
