Poker is a card game in which players place chips (representing money) into a pot to compete for the best five-card hand. Each player attempts to control the amount of money in the pot based on the strength of their own hand and their prediction of what their opponents are holding, which may include bluffing.

Professional poker players rely on a combination of innate card sense, psychological conditioning and an understanding of probability to read their opponents and profit from their superior instincts. They are also masters at extracting signal from noise across multiple channels, including visual and verbal cues such as eye contact and body language, and integrating this information both to exploit their opponents and protect themselves.

The basic ranking of a poker hand is determined by its mathematical frequency: the higher the chance that a given hand will occur, the higher the rank. Ties are broken on the basis of the highest card outside the pair or three-of-a-kind (in a full house). There are, however, many variations on this basic rule in games with wild cards or other anomalies.

When describing a poker game, focus on the nuances of the scene rather than the specific mechanics of the game. Details such as who flinches, smiles and chews gum can all be telling and transport readers into the world of your story. In addition, the player’s reactions to their cards can provide a rich source of dramatic tension and plot conflict.
