Poker is a card game that pits players against one another in a battle of bluffing, strategy and luck. It can be played in many formats, with a wide variety of rules. Often, the cards are dealt face up in the center of the table, and each player must place a bet (called an ante) before any cards can be revealed. The highest hand wins the pot of money.
In poker, the players know that there are 52 cards in the deck divided into four suits with 13 cards each, and they can calculate the probabilities of certain cards being in their opponent’s hands or on the table. But they can never know these probabilities for certain, and the choices they make around whether to fold, call, or bet depend on these probabilities and their anticipation of how their opponents will play.
Professional players are experts at extracting signal from the noise of their environments, using multiple channels to both exploit their opponents and protect themselves. They do this by reading and interpreting signals from their opponents—including visual cues, betting patterns, verbal cues, and the tone of voice used—and incorporating these insights into their decisions. They also use software to build behavioral dossiers on their opponents and collect or purchase records of their opponents’ “hand histories.” This is a form of deconstructive analysis that is crucial for poker success. In life, the same principles apply—you need to balance risk and reward in order to achieve your goals. Pursuing safety leads to a low return on investment, while taking a moderate amount of risk can lead to great rewards.
