Hi guys, for some reason this hand bothered me, not sure if it should.

Live 4-8 game, the villian is a beginning player based on my observation of him fumbling with chips and having to ask what the bets sizes were. He did play some strange hands, offsuit junk, etc. Haven't seen him raise much, but only playing with him 45 minutes so no other solid read besides the above.

I have AA preflop in the big blind. Villian is in MP2.and limps. A few other limpers. I raise and all call. I think there were 6 players total so $48 preflop, decent sized pot already.

Flop:

I lead out, villian calls, everyone else folds.

Turn:

I bet, villian raises..........what's my line for the rest of the hand? Do I get aggressive or go into call down mode? Can I fold to a 4 bet if I threebet the turn?

I just called and then the river was .

I now ????????

edit: so to be clear what I am asking on the river, since theoretically the river 4 reduces the chance somewhat that he has the case 4, do I bet out, check/call, check/raise? Will he check behind with a Q or other pocket pair? I don't think I can fold to a raise here.
