Agree with betting turn but I'd fold to a check raise (double x/r with air at 25NL, yeah ok).
OP, what is it about AA specifically that makes you fear a x/r? I feel many players are overwhelmed by an entitlement to get to rivers/showdown with their entire value range, then somebody renamed it
Pot Control to make everybody feel better. Value hands that I would fear a x/r with OTT are hands that are drawing live vs BB value range. Something like K
T
. AA is drawing near dead v BB value range so what's the big deal?
A class of hand you didn't suggest he could have on the turn is something like yeah K
T
, a bluff that paired, in addition to hands like 8
x. Betting gets value from those and if he double x/r'ed on a turn that many would perceive as better for your range then frankly the least he deserves is for you to get go of AA.
