Hit him on the nose with your fist, hit him hard, hit him on the nose with your best strength. If he is normal, his nose will bleed and then he will be punched in the heart.
Kick both sides of his knee, preferably the outside.
If you are pinched by him, hit him on the chin, kick him in the crotch and hammer him on the back with your right hand.
Hmm. How interesting
