Cut kick, normally if i fight with my partner in sparring I kicked near the neck area and when i do again so my oponent keep blocking the upper body and forgotten to block the leg, to bock the low kick one way is to stand your feet both face the oponent not the side or your oponet will low kicked your thigh back leg or inner thigh, or bring your front leg as a muay thai guard the same time but not the shin bit or you'll knocked each other shins, also if you fake a kicked a mt will blocked then you can do a cut kick.
