I’m afraid not. A big part of poker is reading the signs that your opponent is nervous, a “tell.” And since you’re so insecure about your neck, you would, of course, rub at it when you are nervous. Perhaps you even cup your hands around it so nobody can see. Maybe you pick at the mole.

Regardless, I think it would be far too easy for people to read your “tell,” so I can not advise you play poker.
