No fake smile is weak
Lots of chips is weak especially adding some just before betting
Throwing chips at you is weak
Web you ask why they are bluffing and they voluntary say they are not bluffing or I'm sorry but I can't fold this one or something
Quietly mentioning the bet amount to the dealer
Looking at the clock is usually strong
All the italics I do naturally with all my hands, just something I do. The throwing chips toward the person is so true. Just watch out for the things like that people do. When i first started playing live i avoided giving anything away, now i focus on other people. Works a lot better and its amazing how much you pick up, like cutoff looks like he is folding pre until it folds around to him etc. People generally have a solid tell with their hand position, ie when they know they are folding they have their hand a certain way, ready to flick the wrist and have the cards in. Watching the very corner of peoples mouths is rock solid, it shows your true emotion for a split second.
I like folding the turn here i think, but I don't hate peeling another off.
