How not to Play AK?

There's no way he's calling with JJ or TT if you bet.

The average Party .5/1 unknown will call the river unflinchingly with either of those hands.

I think this is where you're going wrong. You're assuming your opponents have the same calling standards you do and are playing rationally and thoughfully, as you are. You are wrong about this. Villain has already showed that he isn't playing rationally; like you said yourself, no matter what hand he flips over, we already know he misplayed it. Why do you automatically assume that a guy who butchered his hand on either the flop or turn will suddenly wake up and play sanely on the river?

(FWIW, I agree that AK is the most likely hand for villain in the sense that AK has been played the least badly out of villain's possible range. We want to bet the river to grab an extra half-bet from the straggler).
