Poker is a card game played by two or more people. It is a game of chance with many mechanisms for players to misinform other players and to protect themselves. The game can be played in a variety of ways, but it always involves betting. Players must decide whether to call, raise or fold. The player with the best hand wins the pot of money.
The game is played from a standard pack of 52 cards (some variants use more). There are four suits (spades, hearts, diamonds and clubs), and an Ace (high or low), with the highest suit breaking ties. There may also be jokers, which can take on any rank and suit. In most games, a complete hand is dealt to each player, with the exception of some variants that require one or more forced bets before the deal begins. Players then bet in rounds, with raising and re-raising allowed. At the end of a round, all bets are collected in the pot.
As a writer, the most interesting part of the game is not the cards, but the reactions of the players and the by-play between them. This is what makes the game exciting, so focusing on writing about a series of cards will be lame or gimmicky. It is much better to focus on the interactions between the players, including how they talk to each other and their tells. This can make the story more interesting and help keep readers engaged.
