I regulary play NLHE in my local club (2/2 blinds, min buy in 30) and enjoy it, I'm not crushing the table there but I'm doing fine.
I play online mostly on 1/2 shorthanded, ocasionnally on 2/4 full ring.
And 3 weeks ago I experimented Las Vegas.
I stayed at the MGM so I tried their brand new poker room.
I begun at 1/2 NL with a max buy in of 100$ (thats not a lot) and I felt quite confortable.
I tried also the 2/5 NL max buy in 500$ and I did well also on it.
Some things amazed me a lot, mostly because it doesn't exist at online table, and because in my local french clubs it's very different.
a) preflop raises are huge

In france you are respected most of the time with a 5BB raise preflop. my table was mad or it's usually the case in vegas ?
b) all in are by far more frequent, people don't hesitate to rebuy, in france people usually come to the table with a lot of cash and don't want to rebuy, here people seem to come short-stacked and gamble !
So I wanted your thoughts about the difference between online and vegas !
