It feels like you're behind on the river to AA-KK, AQ, KQ. I could see him occasionally checking behind the flop for pot control and deception with AA-KK, although I agree I wouldn't normally expect it. On the other hand, I could see him checking AK behind on the river a lot.

Was your plan to play it passively post-flop if low cards hit? I don't understand: why didn't you at least bet the turn to protect your hand? I would have bet either the flop or the turn.

Finally, I'm not crazy about playing this passively if you're going to call the turn and fold the river. That is, as played, while I think it's a fold on the river, that probably means it is on the turn, too (again, though, I would have bet the turn).
