In fact, this reminds me of a hand of mine from a few months ago. Check out hand #1 in
this thread.
My mistake was not re-popping the turn with so many "bad" cards out there. The difference in our two hands is only that one of the few "safe" cards came for me and I could call the bluff, and a scare card came for you and you couldn't call.
In fact, the more I think about it, the more I like your overbet on the turn given the fact that so few rivers are safe.
P.S. If you look at hand #3 you'll see me limping A5s. Heehee.
