my suggestion
imagine beating the shit out of him savagely...over and over again...until you start to like it...then if you still get that twinge...embrace it and let the fool have it and after you throw the first punch, dont stop....dont stop until he is on the ground, just keep swinging, grab his hair and let a few haymakers go into his face and after a few of those he will probably be dazed so let off a few elbow shots.
dont fuck with body shots, they dont do much.
if he somehow gets behind you...dont let him....but if he does....hes probably going to try and choke you out...if he does...dont try getting his arms away from your throat because youd just be wasting energy...instead, just keep elbowing him in the gut.

and above all....dont get into a pattern, go crazy on the muthafucka
