How much respect do I give this guy?

Granted the king doesn't make my hand invulnerable or anything. But what should my line have been? Check fold? That seems too weak. Better to block bet the turn to give everybody a chance to define their hands and get more information. If I am beat and I check, I'll probably have to face a bigger bet than what I put out there so unless you're advocating folding the turn it seems like a feeler bet was called for there.
