Poker is a card game where players bet money into a pot based on the rank of their hand. The game is over when one player wins all the money that was put down as buy-in at the table. The remaining players may then share in the pot as well, depending on the rules of the game.

The game begins with one or more players placing an initial forced bet (either blind or ante). A player can match the amount raised by the preceding active player (called calling) or raise it further (called raising), or he can fold, losing all his chips in the hand and dropping out of the round.

Once a player has his cards, he can make a “showdown” to determine the best hand. A showdown can also be a draw, in which case the pot is split amongst all the players with the best hand. The pot can also be a side pot, in which case a player is only eligible to win a pot to which he or she has contributed.

Poker is a fascinating game with many different strategies and psychological nuances. It can be used as a metaphor for many aspects of life, and its inherent unpredictability can mirror the twists and turns of a compelling narrative. In addition, the concept of a poker face can be a powerful tool for characters who conceal their true intentions. This, in turn, can add layers of depth and intrigue to a story.
