hand

both players unknown

Always a spot I'm not sure about. On the one hand isolating myself vs a stronger range, specifically T9 is a threat, OTOH I don't wanna flat and even entice the BB to come along with all sorts of hands when most turns will significantly hurt the value of my hand, even more when he pots it. I was asking myself if fishes would ever think about not paying off at least the raise with any overpair.
If this is just a call, how do I play an offsuit 2 or Q on the turn if the BB folds?
