Americans and Canadians
bluff a lot...(not all, but I keep an open eye on their betting)
Some are very strong, and that comes from longer experience...!
Russians, have an aggressive style, because they like to make money fast and think it's going that way.
(Some are stronger, but they play not too aggressive)
Italians, I agree..!!! Have seen some and they bet on any two like they have AA!!!
Some south Americans play aggressive too, but not bad(so I am careful with those guys!)
Met less french players, but the ones I played think are pretty good players.
In the end, it really doesn't count from where a player comes from.
Be respectful and play them as they are strong, until you know they are not.
Anyways I think more respect on the tables would be good for all.
You don't need to be an a-hole to win...
