2/4 holdem question/problem, please comment

[lilkunta2]

Party 2/4 4 handed. im in the BB and both players fold the small blind who completes. I raise with AA

he calls

Flop: 5c-Jc-6h He checks, i bet, he calls
Turn: Qd CHeck, Bet, Call
River: 5d Check, I bet, HE RAISES, I hesitate and
call

My question is..... can one make a case here for just checking behind on the river? i think its wrong but
2) once he check rasies you, is there any point to calling?
was calling wrong? what would he checkrasie me with that didn't beat me? its VERY UNLIKELY that he would check rasie me with out trip fives so is it even worth it to call here. i need feedback from experienced winning players on this one.
