I'm having serious troubles putting villain on a hand that doesn't fold to the push on the river. Even if he does call with AQ/AJ, I would guess it would usually be a mistake against fv. (Let him correct me if I'm wrong.) I would probably move in against a decent player (much less vs donk.) I do have doubts about it though, since I also have troubles assigning villain hands that just keep calling (I'm pretty sure set/2pair raise somewhere.) Except mentioned AQ/AJ hands, maybe 5d4d, QdJd JdTd? He would raise with Kdxd, would he?

This of course can be way off, as you both seem on a loose side, so recent history might affect this a lot. Same with the river bet size, it just depends...
