Shin Choke

This is a very simple choke performed after a throw or other sort of take down (preferably while still holding onto the arm or wrist of the opponent) and being close to the opponent on the ground you drop your knee so that your shin lands on their neck, crushing the windpipe. Using the shin like this channels a huge portion of your body weight into the choke on their throat leaving them with little they can do to avoid it before they pass out from lack of air or become compliant with the defender. If the opponent is much larger than you and they may have the arm strength to lift you off of them before the pressure on their throat becomes too much a quick downward punch or hammer fist to the solar plexus will disrupt the diaphragm in combination with the choke depriving them of air.
