AA River Decision against TAG

[_Kevin_]

Villian is a TAG (15% VP$IP, 6% PFR, 2.25 post flop aggression over 400 hands). I've put him on a big pocket pair. Is my flop and turn play OK or should I have slowed down at some point? I've ruled out J's since he slowed down. I'm thinking K's or Q's after the turn play. A's seem extermely unlikely but possible and T's seem even less likely. I believe he would call down with KK or AA and go for a check raise with QQ ot TT. I really only see 2 options based on my reads: 1) Take a free showdown, 2) Bet/Fold to a reraise. Am I wrong to think bet/call is not an option? I suppose based on the likelyhood of hands bet/fold is the best option. Is my thinking way off here?
