Avoid Obvious Tells
this may seem like a strange thing to put into an article on psychology, but really a tell is a physical manifestation of an emotional state. In other words, tells are you making movements based on your psychology. Don’t believe it? Google the ex-CIA interrogators who served as human lie detectors. They have a list a mile long of movements, gestures, and mannerisms that indicate someone is lying. You should have that, too, for when the other folks at the table are bluffing, excited and every emotion in between.
Once you have that list, make sure that you don’t display any of those tells. Play online poker in front of a mirror and coach yourself to stay dispassionate and stony. Play with sunglasses, a cap, and hoodie if you must to avoid reveal your inner emotional state. Doing so will immediately make you a better poker player. Even if you never master the art of reading tells for anyone else at the table, if you can prevent other people from reading you, you will always be a better live poker player who won’t give the rest of the table information about what you are thinking.
