and i still like calling the flop because i do think there's air in his range. given he has been aggressive and this is a board that he knows you know hits his range, i'd expect him to bluff raise the flop. I'm not sure he would run a bluff for stacks though, because i don't think he'd expect you to fold QQ+. though because he may not continue his bluff past the flop you may be correct to fold the flop.
