Lunging front kick to attack pressure points to the lower part of the attacker’s body groin, liver or floating ribs.
Scissors, to attack pressure points in the upper body of the attacker. This kick is done from the spot as the attacker is lunging forward with a low knife hold in the rear hand. The name scissors comes from the first lift of the base foot and dropping it down as the kicking leg moves up.
That scissors motion facilitate ease in a torso twist placing both heels on the same line to the target and letting a slight backward tilt of the torso, yet keeping balance with both feet off the ground. Note that scissors kick is done from the spot for defense and ease of timing. You can run and do it but then it becomes a jumping kick. Also in any case with this kick the jumping leg is the kicking leg.
Of course you can also sprint and execute a jumping front kick where the kicking leg is not the jumping leg. You can also kick with the cross leg(the leg that is behind the front leg). But from a still motion in a lunging range, kicking with the front foot is always preferable, as it is closer to the target and gives better control and speed without opening the centerbody leaving it defenseless for a moment.
Heart Stomp Kick, to attack the chest bone. This kick is done similar to the lunging front kick, only the knee of the kicking leg is swung above the waist in the direction of the attacker’s neck.
Defensive kicks against kicking where the center instep of the kicking foot is aimed at the thigh, knee, ankle of shin of the attacker’s kicking foot, or his tail bone. When aimed to narrow limbs like part of the legs, the instep is being positioned at 90 degree to the limb to avoid slippage with impact.
This type of kicking entails (lifting the knee to 90 degrees and extending the foot prior to impact, either 45 degree to catch limbs usually legs at the shin or thigh or heel or tailbone if the opponent is turning his back.
The ease of executing this kick is achieved by leaving the ground with both feet prior to the kick to facilitate natural re-positioning of the torso and base foot to for body weight and balance supporting these kicks. The impact is achieved by a static position of the defensive kick and the momentum of the attacker!
