If he is that tight, in NL25 you can probably be pretty sure you're up against aces. From what i've seen, tight players at that level normally reraise 3x with the hand range KK/AA only. You could try to min reraise his reraise...if he goes all in or reraises you 3 times again you can pretty much be 100% he has AA (outside chance of KK...i've had AA vs AA before tho so it is possible).
Unless both your stacks are very large, in which i say call and hope, i would probably just push. Today i was AA vs KK, and as soon as the guy reraised my reraise all in i typed "aa vs kk hf" and called so it really isn't that hard to tell what cards tighter players have. HOWEVER, yesterday i was also AA vs KK, i typed the exact same thing, because it was that obvious, and i got rivered. So even in the worst case scenario you're still going to suck out 20% of the time.
I think i would raise it to 5$, and see what he does. If you reraise his reraise, unless he has aces that is what he will be thinking you have. So with KK or anything else he will hopefully just call (or push all in lol pretty hard to tell). It's a hard hand to get away from, because presuming you are right, you still have decent odds
to suck out. If he is tight, i personally would only feel the hand he will raise it up to 10$ or all in with would be aces.
Another question is: what is your PFR%? If you raise alot he might reraise you with somewhat less than AA.
