i think you've got to bet-fold. it sucks, because you're going to fold worse hands and also open the possibility of getting bluff raised by them, and you're ahead of more of his range than you're behind. however, i don't think he bluffs both streets often enough for check-calling down to be profitable, and i also don't think he bluffs you off the best hand often enough for there to be anything wrong with bet-folding. so i guess you've got to go with the lesser of 2 evils.

of course, we don't know that he'll bet the turn after we check.
