When he called my 4bet I put him on AA, KK and VERY doubtfully QQ or AK.

If this is the range you put him on then a call looks in order to me.

Personally I would discount AA (tries to get it in PF) and weight AK higher, and would therefore raise this river.

his line post flop can be aces. I don't see any reason why he'd check any pair on the turn besides aces (discounting 44/55). I think this is a value bet from a poorly played AK/AQ hand.

check on flop and turn is fine for pot control. i would just call the river with the range you put him on in mind. When you take AK into account i would shove river.
