I have tangled with him once before when he limp/called preflop with AJ and got it all in on a J high flop.

This one left me really confused. He is raising 10% but there is no way it is going to be this tight from the button. Maybe something like any ace, pair, broadway and some funky connectors and 1-gappers. Because of this I know AQ is going to be a re-raise and not sure if this is disputable. Although, his raise of .75 is less then the usual standard raise and may even represent a bigger pair. I am not sure if he would 4-bet me with big pairs. As for the rest of the hand I struggle to narrow down his range and figure out what he could have.

What does everyone think?
