i am pretty sure that those who have been playing poker traditionally are well versed with reading opponents in person and that is what gives them the edge that is how they find profit from playing poker
analyzing other factors do not matter much when it’s live
Reading opponents in person or guesing the cards player? I don't think it can help you to know if you have a winning card than the opponents because nowadays they usually use their expression as a bluff to win. That is, in my opinion, the advantage of online poker over live poker, which usually involves reading other players in person, because in an online casino, you do not have to hide your emotions, and other players cannot use them to make better decisions but the real problem is in online poker you can't determine the authenticity of the distributed cards I mean, I rarely see them shuffle the cards before distributing them, whereas in live poker, after the shuffle, you have the option to cut them before the card are distributed.
