There are numerous differences with regards to playing live casino poker as opposed to online poker. One such difference is in how live casino poker games tend to be frequented by players that are usually plugged in for longer sessions. This means that the effective stack sizes are much deeper in live casino games as opposed to online poker games.
There are numerous knock-on effects of that and one such effect is that it is often difficult to win a huge pot of say 600bb or more in online poker. This is to do with a combination of reasons but mainly it is to do with the fact that you rarely get to play long enough and so these huge double ups happen less frequently than they do in other forms of poker. Also, it is easier to be more serious when you play online poker as well because of the fact that there is no interaction involved.
It has been a long time now since I last played live casino poker and to be honest there is really no comparison between that and online poker in terms of the number of hands that you can see per hour. Many live casino fans simply will not trust online poker but these days the big sites are almost as trustworthy as banks (just don’t mention FTP). So it is really horses for courses and you either love one or the other but rarely both.
