Kicks above the belt line will usually result in your leg being grabbed by your opponenet in a real fight. Use of the hands or kicks to the knees or ankles ar your best bet. Granted on slower opponents a step behind side kick to the stomach is brutal and a fight ender but undersetimate the luck of your opponent. I may be wrong in this, I have been in many real fights but have never used TKD in them. Please feel free to correct me if I am wrong.
