What to do with this guys large raises

[iceman5]

I have a guy who I play with all the time. Hes a small winner in the game and I dont have a real problem beating him, but I have one question.

He really likes to slowplay. He only raises like 2%. he limpes big pairs all the time, but every now and then he will raise to $110-$130 after 1 or 2 limpers. Ive seen his cards twice when he did this and he had AQ both times. I suspect he does it with AK also, but not every time obviously since he rarely raises.

He wil always have a full buy in or more because he reloads if he loses a bit.

The question is this:

How do you handle these raises?

Would you be willing to push all in with any pair knowing he probably wont call? I really doubt he ever does this with a big pair, but anything is possible.

Would you push in with any 2 cards? He cant call with AQ. I have no idea if he would call with AK.

What would you do with AA, KK, QQ? Flat call and play the flop assuming he doesnt have big pair?
