90% of Brasilians are bad and terrible players... All-in with any Ace, give him just 1 card, I mean 1 Ace and Brasilian will say "It's enough, I don't need the second card, I'm ALL IN".
Very weak bluffers, most of them play like they're scared, many times seen the situation where Brasilian player re-raises on flop having a unbeatable monster hand like full house or quads... instead of just calling the bet with such monster
hands and try to involve more players for a bigger pot, they re-raise and isolate players from turn and river cards...
And OMG so many times I have seen final tables where hundreds of Brasilian observers chatted and cursed opponents of their Hero of the table... It was like a horde from favella attacked a poor British guy who won the pot vs Brasilian guy...
But at higher limits I observed few experienced players who played a really nice poker. However that's too bad that majority of Brasilians don't play good poker like some of their neighbors and don't behave well at the tables.
Well
brasil is a big and nice country, with it's own positive and negative sides, and i believe that majority of Brasilian player that I've met at the tables are playing HoT version of poker because the climate is hot there
