A card game of betting and skill, poker is among the most popular forms of gambling in the world. Its history dates back centuries and continues to evolve with new games, variations, and players.

In poker, players use chips to represent their values for a hand. A white chip is worth one bet; a red chip is usually worth five whites; and a blue chip is worth 10 or more whites. Players can check, call, raise or fold in turn as they play a round of betting, adding money or chips to an ever-increasing pot.

If you hold a strong hand, you can increase the value of your chips by forcing other players to call your bets and forfeit their hands. You can also try to bluff. If you make a bluff and succeed, you can steal a pot. But don’t be too obvious about what you have — if your opponents know what you have, it will be difficult to deceive them.

Advanced poker players understand that a hand’s value is relative to the situation. They study their opponent’s range, the set of hands they are likely to show in a given situation, and act accordingly. For example, you might have kings in your hand, but if the player to your left has A-A, then your kings are losing hands 82% of the time. If you play them, your chances of winning are slim to none. Instead, you should fold.
