This is really cool, the fact that the whole world can share the same game, the same table. But the massive dominant style these days is the maniac loose aggressive one, and more than never players open raise pre-flop, 3 bet, 4bet..., quite different from the old school poker.
But, depending on the players mood, at a certain game, they will play tight, aggressive, tory, maniac, no matter which country or region they come from.
I refer it by even observing myself. How many times I play intentionally bad, like a maniac, no matter which cards was dealt to me. If a player plays not as good as it should, it doesn't really mean he/she is a weak or a beginner player or even which place it come from. It may be be just the mood she/he is having at certain moment, also sometimes playing in a hurry, wanting to get off due to another task that must be accomplished, compromise etc etc. It's difficult to judge, better to judge ourselves first to get a good bottom line.
