Since most of us won't ever play directly against each other, be bold and share one or two of the biggest tells that you have seen in yourself.

I have two. When I am making a risky or ill advised move (a bluff, or a very wide raise or call), my nose itches and I scratch it. Also, when I have a made hand, I act faster than when I am bluffing or on a draw.

Common, but my hands are incredibly shaky when I have a good hand.

When I start getting chatty at the table, it's a countdown to a spewy blowup. Starting to tilt and somehow it seems like I talk more to tell myself I'm fine when I'm far from it.

Should quit session soon or will punt off a couple buyins.

-Talking in general during the hand, it just gives away what i have literally...
&
-Acting too quickly with nutted hands vs. acting too slowly taking marginal decisions (timing tells)

1) The motion of a hand towards the face/head/ear is a very common 'worry/weakness' tell.
2) Acting fast is usually sign of weakness as well. But Zach does a great job breaking this all down in his book when you look at different 'spots' ... opening bet, facing a bet, facing a raise and waiting to act are all different and the same 'common' tells can actually mean different things.

3) I rely less and less on the shaky hands. I look for changes in something, not just 'the something' in general. If a really good chip riffler all of a sudden starts spilling his stacks then there must be something else on his mind ... like a weak hand.

4) With talking it's again a change in 'the norm' for a player. If a chatting player all of a sudden stops talking PF ... it's probably because he has a decision to make (strong hand). Folks with strong holdings don't want to draw attention to themselves so they quiet down (and hide) from their opponents.

5) Timing tells along with a player staring at the board usually mean weaker/drawing type of hands. A player wants to make sure (double check) he know how many outs he, or his opponent, has before acting. Not as common with flush draws since those are easy to spot, but the more a player studies the potential draws out there the more you can try to read into it.

I had a player tell me that he had me figured out for sure ... When I would flip my chips out for a bet/call I was weak, but when I stacked and slide my chips out there I was always super strong. What he didn't know was that I am very aware of this and purposely use it 'against' different opponents in whatever manner I wanted at the time. But basically if there's more than 8 chips involved in the action I'm stacking and sliding (or cutting) just to make it easier on the dealer. GL

I THINK this is my biggest tell as well.....

I hands shakes whenever I'm in a hand so it's all good.
I like to look at my cards as soon as I get them and have an idea about if I'm play the hand, I guess that doesn't help with my table presence.
