After felling an opponent, you should control him and deliver a combat-ending strike

Two effective tactics against Kick-Boxers are to strike their legs when they kick, and to fell them onto the ground before they can effectively withdraw their kicking legs. It is important not to strike or block a sweeping kick. Strike a sweeping kick following its momentum, or avoid it and immediately move forward to fell the opponent when his leg has just past. Control him on the ground and apply a combat ending strike.
