Poker is all about outsmarting your opponents. But in a game that requires you to perform under pressure, if you don't keep your emotions in check and your concentration on point, your opponents will be able to outsmart you. Poker psychology is all about keeping slip-ups off the table.
Additionally, a person addicted to poker may exhibit an inability to control their gambling behavior, continuously increasing the time and money spent on playing. They may become restless, irritable, or anxious when attempting to cut back or stop playing.
