I find that my defencive style has evolved to be mostly parrys (moving the punch away) and cuffs (where you stop the punch with your palm). I want to know if there is a way to make my cuffs and parrys so strong it can hurt my oponents hands. I know it hurts when i smack down hard on the thumb, espesialy when my oponent is wearing regualar boxing gloves! mu ha ha ha. Also just a thought is this cheating in any rule system?
