Pick a spot and push back. You don't need the nuts to bust him, you need a hand thats better than his. If he's doing this constantly, he doesn't have crap most of the time, and he has weak holdings a good portion of the time. You dont need to make top set or the nut strait to bust this guy, check raise him AI with TPTK or bottom two pair and your hand will probably be good or he will fold and you will send the message to him to stuck f'n around with you when you're in a pot.
