I don’t smoke, and I know that many players are irritated by opponents smoking at the poker table. I don’t want to get into the debate about smoking. I do want to advise you, though, that if you’re in a game where smoking is allowed, there is a powerful tell that often surfaces.
If a player who’s smoking bets and then exhales a cloud of smoke, that player is relaxed and probably holds a big hand. If, on the other hand, the player swallows the smoke, lets it out in barely noticeable wisps or doesn’t exhale at all, there’s a very good chance you’re facing a bluff.
