The teep, or front kick, is an underappreciated tool. Often taught as a defense against a slow roundhouse kick, or a way to create space between combatants, it is often overlooked for its sheer power: firefighters used this technique to kick in doors for years (until being replaced by the Halligan bar, and the huge mechanical advantage it provides); others in the door-kicking business still use this when no Halligan bar is available.
Here is a video of a recent Muay Thai fight that is an excellent display of the direct application of an offensive teep.
That was the end of the fight.
