I also frequent a norwegian pokerforum: pokersiden.no. The posters there mainly suck and likes to post badbeat histories or brag about how they turned their 50$ deposit into 250$ in one session. But there are also some high quality players, and most of them play high stakes limit.
I'm not sure if HU is their speciallity, but I know they play shorthanded
edit: I came across this site
http://www.smartgambler.com/index.php?/smart/the_team yesterday and the guy named Lagerbord supposedly busted another high stakes limit player named Bengt for about 20.000$ playing HU a couple of days ago. I guess he can play some HU, hehe [img]/images/graemlins/smile.gif[/img]
