Yes--check fold. The prflop capper has an Ace or KK most likely. Maybe he has JJ---either way you're beaten. You could try to bet the flop and see if he'll fold given the large pot but if that does not work check fold the turn. A check-raise on the flop is probably not going to work and since he reraised your check-raise he has a set in all liklihood.

Either bet the flop or check-fold. I'd prefer the latter in a muli-way pot while the former would be a legit option heads-up. A check-raise is not in my playbook here.
