Ive never really played live but been playing online for a year. The games are faster paced in the sense you will see more
hands in the same period of time IRL.
You can’t read faces and there’s not as much talking
So you don’t read people the same way as you would IRL.
Instead reading a person is how quickly they are betting, raising, checking, etc... if you get an instant 3-bet it could be strong but a slower 3-bet might be a semi-
bluff.
You have to look at bet sizes, how often they’re playing in the pot, the time it takes for them to make their play, how they play the flop, turn, river.
Calling down to the river, then shoving quickly probably means they had a draw and hit the nuts on the river.
Just subtle things you will have to learn to pick up in a little different than live tables since you are not looking at a face
