Description of high chin kick
To perform this kick properly one raises the back knee and releases the leg toward the opponent with the heel impacting his chin. The force of the kick comes from the pelvis and straightening of the knee - which should be sent forward along with the leg. The kick's force makes it quite quick and since it is meant to hit the face and not the torso it is difficult to block.
