The Kick Stance is for use at slightly longer ranges. Basically any time you cannot step and hit your opponent with your punching technique, you should be in Kick Stance. The Kick Stance is more upright, keeping your head neck further away from potential knees and kicks and making it more difficult for your opponent to break your posture and own you in the Thai Clinch (Prumb), or set you up for neck cranks and chokes further down the line. The upright posture also makes it easier to defend against leg kicks.
