This thread is interesting...
I hope the following comments will not be misconstrued as "hard discriminating stereotypes". They're not intended to be...
I am simply interested in cultural values. The following are just my thoughts on how those values seem to come out at the table...
BY FAR, the loosest and most aggressive players I have ever encountered (live) are: young, drunk, white, American, male, NL players who have decided to play LHE for the night, for free drinks.
A close second in the LAG department: young, Asian (particularly Chinese), males. Loose, aggressive, and tricky... Not at first, they come out of the gate ABC but as they enter more pots with certain opponents they start playing more aggressive/tricky against those opponents.
The Japanese that I have played with seem to play loose/aggressive when "it's fun" to do so but aren't the type to c/r, or even value bet, you on the river. It seems cultural... Almost like it would be "unsportsmanlike" to bet the best hand on the end.
A broader generalization is that people from Asian cultures tend to have "more gamble". Males leaning towards LAG, females towards loose/passive... If this is true, it could be because
gambling doesn't have the same "negative" connotations in those cultures as in some others.
Games in the "Bible Belt" tend to be more TAG (more conservative values) than say the LAG games in California...
I'd be interested in hearing how others would stereotype the typical "white American male" NL player. For me, that's a bit of a boot strap problem...
