Number one rule: There is NO rule number 14. There is NO "after initial hit" attack. Hit and run. RUN. Basically, no woman can afford to stay and try to hurt more somebody outweighing her by forty kilos. Use the initial surprise and RUN. Number two rule: If you do the thingie under 15, and if you do it really quickly, you'll probably break the guy's fingers. Apply rule number one then. Sensitive targets: The upper part of the foot, instep. Stomp on it. Knee. Kick it. Groin. Kick as hard as you can. Really REALLY hard. But, the groin is really not a good place. The pain starts only after a time, so the attacker has time to react. And if you try to kick in the groin, be aware that you can be relatively easily unbalanced. The instep and knee are closer to the ground. Aim for them. And they hurt much earlier.
