I haven't played live poker for a while, but as I remember it's very difficult compared to online poker, because you have to hide your feelings but in the same way it could be easier because you can see how people act under pressure
Playing live is more expensive than online, but issues such as variance and bad bets are lower. Particularly playing live is my long term project and possibly I will be at an event of this level.
If you plan to play live to have a great time, you'll be fine...if you think that this could turn into a fulltime job...think again...for every player who makes a living at poker, there's 5,783 who go broke.
I played live poker. You're overwhelmed with emotions, especially when bluffing. And to be honest, it's much more pleasant to play live, but it's still more difficult. We need to control ourselves.
