aa vs someone better than myself (150bb stacks)

[mkflsam]

Guy is a good very aggressive TAG. He appeared to be 27/20 at the time, but later stats show to be 25/10. Still a little inconclusive. I'm almost embarressed to post this hand, but I really need to work on playing overpairs.

Only problem is my hand is a little transparent with the turn call. His river bet almost looks like a block, but why would a possible smaller overpair block this river when may be obvious I have one too? Wouldn't he be better off check/folding here with smaller overpairs, say 88-JJ. I could see betting with QQ/KK because he does have some showdown value and I could've been stubborn with TT/JJ myself but could make it hard for him if I bet big with AA.

Looks more like a value bet after further reflection. I really don't want to be overrun by 30/20 types, but I'm not sure if this is the right spot to pick a stand.
