QQ BUvsCO

Hi guys. So CO is 20/17/7, with a 4bet of 8.5% (4bet range 2.9% in CO) over 16k hands.
- Is it better to get it in preflop in this spot or is he too tight?
- How to play postflop, do we just fold flop? Call flop fold turn?

I am having trouble with similar spots all the time, not sure what the better line is and when to give up (if at all).

mjq.

P.S.: I guess I should be posting NL100 hands in Low Stakes from now on ha?
