Befor i started playing online i was like "hell no, i can only play live, online there is no info beside's person's bet"

Wll i have picked up a few tells from my short hand games. And im sure if you play over .5-1nl these tells will suck.

1. slight delay in reaction to a card
This is usually when im in a HU cash game. The opponent usually cheks or bets turn/river/flop with consistant timing (say .2 secons after the card hits) but many times they will hesitate for .05-.1 seconds when a nice card hits. usually their delayed reaction in cheking or betting, tells me something is up.

2. also in HU when a tigh/weak/shitty (sorry i dont know whats that called LL?) decides to raise pf (after showing that he limps with QQ, AK..) pretty much tells me he gunna try to take this pot down no matter what. if they uncharacteristicly bet hard on flop, i dont take it for top pair or protecting op.

3. HU also i guess.
Flop: 6KK, i chek and he bets the pot. Usually a novice player with K would slow play this hand, so if he fits the profile, i assume he dosnt have k. If he is fairly smart, i will smooth call his bets representing a slow play.

im not sure if these were tells or reads or watever, but the first two really help me beat players when i play HU.

no, i mean when im playing HU and we are flying through hands at fast rate, and i notice a fraction of a second difference in his click, like .05 or 1/10th of second.

long delays are a good tactic to make them think you are thinking (when slow playing a nice hand i will take extra 6-10 seconds "thinking). hence they can be desieving.

If there is no "deafault reaction time" due to multi task, multiple tables, poor connectiuon, i wont give a minor delay any credit.

a 10th of a second! the only time a 10th of second makes a difference is in track and swimming

I use the check fold a lot myself, but I balance this by using the auto check button when I want to slow play the nuts. pretty effective trick

The long delay followed by a bet is a pretty good tell that it's a weak player who is acting to show weakness but has a monster. I don't always trust it, but I'm not going to call down with marginal holdings.

Someone who normally plays quick but suddenly hesitates a bit before a check or bet usually means strength as well. I've put a few people on sets in multiway pots this way that turned out to be right.

Online tells though are very marginal... I'm not laying down TPTK because of one... just if it's a marginal call anyway I may use one in making a decision.
