EYES - no matter how big your opponent is they cannot withstand a shot to the eyes or something thrown into the eyes.
NOSE - Any time the nose is hit, it will make them water and allow you time to either escape or follow up.
GROIN - No need to explain this one
THIGH - A good hard kick to the thigh leaves most attackers laying on the ground.
