Poker is a card game that is played around the world. Millions of people play it either live or over the internet and its popularity has been boosted by television.

The rules of Poker vary among games, but in general a player receives one or more cards and is required to make bets to compete for a pot. The game is divided into multiple betting rounds, which begin when a player places the number of chips needed to make his total contribution to the pot equal to or greater than the amount contributed by all players before him in a particular betting interval.

When a bet is made in a betting round, all the players in that round who are still in the pot have an opportunity to call the bet or raise it if they have not already done so. If all players check, the betting interval is over and all players in the pot remain in the game.

Players must also decide if they want to continue playing until the next betting round. If they do not, they must discard their hand and may no longer compete for the pot.

If a player has a strong starting hand, it is a good idea to up the stakes as soon as possible. For example, a pair of Kings, Queens or Aces is a very premium opening hand at a 6-max table. In this case, a good strategy is to raise and reraise to give your opponent a chance to see a few more cards before they fold.
