Depending on our M ratio, I might either make a call with anything and play back at him postflop if he seems weak, or if our Ms are low enough, I'll go over the top or push with some pretty marginal hands to resteal. I hate these buggers too (I myself am one of them alot of the time ) and you CAN'T let him keep stealing from you. You have to take a stand and let him know he's messing with a guy who won't give up his blinds easily, and he'll back down.
