Even though you have only 144 hands, he seems tight. Lets say his raising ranges is a bit looser than what you said --AA-TT, and AK or AQ. Given that you have AK:

1. There are 6 combos you're way behind (3 other AA combos, and 3 other KK combos)

2. There are 12 combos you're strongly ahead of (12 other AQs)

3. There are 27 combos you're around even with (6-QQ,6-JJ, 6-TT and 9 other AK)

given the above (that the range of hands you are up against is at worst equal with you), and that you have position for the rest of the hand, and that a 3-bet should take the blinds money as well, its a definite 3-bet
