I have no idea how this generated such a huge thread. This is the easiest fold ever. Pot odds are irrelevant when you're beaten every single time. The ace was a great scare card on the turn so any bluffing from villain would have been in the form of a double barrel. Villain's turn play is pot control, indicating a hand with showdown value, and nothing has changed on the river to suddenly turn it into a hand that needs to launch an insane c/r bluff against an opponent whose range includes a ton of sets and top twos.
