The game of poker involves betting and raising chips (representing money) in a circle to make the best hand possible. The highest-ranking hand wins the pot, and winning hands are typically comprised of a combination of hole cards and community cards. In addition to being a game of smarts, mental toughness, and attrition, poker is also a numbers game, and the understanding and application of probability is crucial.

To begin a hand, each player must “ante” – place an initial amount of money in the center of the table – to get dealt two cards. From there, players can choose to call, raise, or fold. Players must always place the same number of chips into the pot as the person to their left if they are calling. In the event that a player raises, they must then match the previous raiser’s bet in order to continue raising.

If a player does not have a good hand, they may wish to “stay” or “fold.” To stay, the player must put a certain amount of chips into the pot that is equal to or greater than the total contribution of the person to their left. If a player wishes to fold, they must drop out of the betting until the next deal.

The highest hand in poker is a Royal Flush (10-Jack-Queen-King-Ace of the same suit). A straight flush consists of five consecutive cards of the same rank, while three of a kind is made up of two cards of the same rank and one card of another. High card breaks ties when no other hand qualifies.
