Villain has been playing fairly loose (27/20). Though he hasn't done anything exceptionally aggressive/spewy in the time i have played with him (~100 hands).

I feel that villain is holding a hand like 9-8 or MP+ FD enough that i should felt this hand once i c-bet the flop. Given that he raised my c-bet from UTG into 2 other players though, i think i need to discount those hands somewhat though. Should i felt the flop as played?

Is checking the flop an option - bet/folding the turn if checked around or calling a bet and bet/folding the turn? Do you prefer this line?
