Poker is a card game in which players bet money against each other with the goal of winning a pot of cash. Players reveal their cards at the end of the round, and whoever has the best hand wins the pot. A player can make a bet (put money into the pot), call (match another player’s bet), or raise (bet more than the last player). This game offers many mechanisms by which players can strategically misinform each other about their strength of hand, such as by using gestures and verbal cues.
In poker, as in life, it is important to weigh risk versus reward and take calculated risks when possible. Sometimes a bad starting hand can be overcome with clever bluffing, as in the case of a novice player with a pair of Aces losing to another player with two 9s on the river who called his flop.
It is also important to keep in mind that poker games can be played over dozens of rounds (hands) and hours, so it’s critical to create tension by showing the gradual increase in odds and tension over time. Describing a few hands at the start may seem lame and gimmicky, so focus most of your description on how players react to the cards they receive, e.g. who flinched, who smiled, etc. This is what makes games like poker interesting and worth watching. Moreover, you can always use the written code of Poker laws as your final arbiter for any disputes during play.
