If you call the c/r on the flop I like the turn call because I makes so little sense for a random donk to double barrel when the K hits (is he really calling your raise with K6/K7? or 67 oop?). If you think this guy is a donk and that he keeps c/fing I don't think he is the type of individual with value bet A7 relatively thin.

I like a river fold (gross if you spike a 5 or 6 tho). In my experience random donks don't mind the c/r when it looks like you may be cbetting with air and then turn bet again when the "scare" overcard hits, but they won't follow through with the third barrel.
