Why not bet/call? PFR could easily have AK. I don't like a 3-bet because once you are beat you are getting 4-bet 99% of the time, and maybe not even called some of the other times. It's good that you are confident enough to fold to a 4-bet though.

With that said, I'd say that I never even make it to the river. I maybe fold preflop depending on the lineup, and more probably fold on the flop. I don't condemn the OP for calling preflop however, because some people play cards like this better than I can.
