His minraises are stupid, weak, and give no information. He looks scared so I'd be really careful when he does get all in. Anyways, I like your reraise and I feel better about getting it all in here because he was the PF raiser so its not as likely he has 45, 33, 66, or 77. Two pair is a hand thats best decided on the flop in my opinion because theres a lot that can go wrong if you wait. If he does have you beat, pay it off and walk it off.
