Fold, is that the answer you were looking for. I don't know if I play this hand OOP, then I'm never checking this flop (But then again that's me, I'd rather find out, where my oppent is). Checking this flop does not help us out by gathering any sort of info from the player, does it? It's actually opening them to bluff us out (I really doubt your ahead though, so In all fairness there not really bluffing you out, if that helps make you feel any better).
But like I said you should've just folded that B.S preflop
