re: Poker & 2nl - nut flush on Turn, bet ?
I find that always betting your big hands is by far the way to go at these limits. Players will call with just about anything, and the times you get paid off vastly outway the times everyone folds. Just keep betting and eventually some calling station will hand you their stack with a 'I hate money' post-it attached.
Incidentently someone just gave me their stack after running their pocket eights into my quad kings after i raised every street, just reinforces the keep betting strat.
