Villain is a nitty reg running 18/16 with a 3b of 6.2 over 200 hands, but seems aggressive post-flop
a few hands ago I saw him nearly pot the flop on a paired low board (something like 775) against a fish so I just assumed that he cbets big in general

I know that 4bing here would be EV+ based on fold equity and I'd have to call it off getting the right odds vs. QQ+,AK
but since I didn't 4b him yet, and expect him to nearly pot the flop as the PFR and we're IP, is flatting > 4b/get it in here?
