Fold. You might be ahead but I just can't see myself calling off a healthy stack with AQ given how you've described the situation. You have characterized yourself as tight (even though raising 3 times in an orbit might suggest otherwise). You also say that he likes to limp a lot pre-flop and is aggro when heads up on the flop. There's no mention of him being aggro and coming over the top like this pre-flop. There are very few hands you are ahead of here. Even an aggro person probably doesn't risk his tourney with Ax or KQ and you're obviously behind AK and all pairs.
