Defining the Side Checking Kick
The Side Checking Kick (Yopcha Momchugi) is a specialized defensive technique characterized by its dual function. Its two primary purposes are: 1) to block the attacking foot directed at the defender’s low section, and 2) to impede or check the opponent’s movement. A checking kick (Cha Momchugi) is unique because, unlike most kicks, the kicking foot is kept momentarily on the target during the block. The primary blocking tool used for the Side Checking Kick is the side sole (Yop Bal Badak). The side sole is formed when the toes are properly bent upward while the ankle is bent slightly upward.
Execution Mechanics and Targeting
For the Side Checking Kick, the target areas are typically the tibia or knee area. Critically, the blocking tool must reach the target in an arc motion. This circular trajectory ensures the block is a true checking motion rather than an attack. If the kick is performed such that the blocking tool reaches the target in a straight line, it is considered incorrect, resembling an attack rather than a blocking motion. Additionally, the blocking tool (side sole) is listed among the tools that play an important role in middle blocks, along with the side instep, footsword, ball of the foot, and back sole.
Strategic Purpose and Counter-Attack Readiness
In both of the Side Checking Kick’s functions—blocking a low attack or checking movement—the foot must be ready for a counter-attack or any type of consecutive action. This prepares the defender for immediate offensive follow-ups. The Side Checking Kick is used in sparring contexts, such as Foot Sparring (Bal Matsogi), where the defender (Y) may use a Side Checking Kick with the right foot to respond to the opponent's (X) low front snap kick. In a sequence against a low front snap kick, the Side Checking Kick with the right foot is executed, followed by a high side piercing kick with the same foot.
Training and Related Techniques
The Side Checking Kick is used in combination with other techniques in training drills. For instance, in a walking stance drill, after striking with the under fist, the practitioner executes a Side Checking Kick with the opposite foot. The technique is also used in advanced training methods like Dodging Kick (Pihamyo Chagi), where the defender uses the technique while flying away from the opponent. The Double Side Checking Kick (I-jung Yopcha Momchugi) is also noted, though only a vertical kick is possible for this sequential technique. The Side Checking Kick is related to the Front Checking Kick (Apcha Momchugi), which uses the back sole supported by the ball of the foot and targets the chest and solar plexus.
