Not as trivial as people would think. The UTG raiser has passed, yes?
I am leaning towards the fold but it's close imo - we can't really assume the bb is a total nit and he could just be thinking that you are 3-betting light against the young kid, surely?
JJ I pass, QQ is borderline. It just seems too strong in this position to pass. Yet I probably do...
Readless middle aged Asian guys aren't at this level of thinking - a 4-bet from the BB is one, possibly two hands.
Middle aged/old guys - assume ABC players unless you've seen evidence otherwise.
