I dont concern myself with "timing tells" nearly as much because with more multi tabling going on than ever before - its easy for players to get hung up on other tables. That being said -- when you face the good old "tank/raise" its generally NEVER a bluff. If someone runs their time bank down and raises you out of nowhere, its almost always nutted - to be quite honest, i cant remember an example where it wasnt lol.
3Bet sizing -- click back 3bets are annoying and i find the majority of them to be VERY strong hands, like QQ+
PFR Variations -- your PFR bet sizings should NOT EVER CHANGE - but i see villans all the time going from 2x all day to 3.5x or 4x out of nowhere -- that gets immediately noted and is generally a hand of considerable strength -- we exploit this by over folding and ONLY playing the top of our ranges - larger bet sizes cause players to "condense" their calling range - thus making them much tighter -- so if you are one of these players who always raises bigger with your AK and AQ, all you are doing is chasing out worse and getting same or better to call. I see this one ALOT.
These are the ones that come to mind most for me off the top of my head.
That being said - i think rather than actively looking for tells, we make much more $$ by understanding how to play well post flop, properly ranging our villans, and understanding why we are betting and what size we are using -- IE: betting for value or as a bluff - and value = whats worse that can call and how much? // bluff = whats better thats folding, how much will it take to get that hand to fold?
