Defence

Checking turns the shin outward and lifts the knee so an incoming low kick lands bone against bone rather than bone against muscle. It is the only defence that actively punishes the attacker: a properly checked kick hurts the person who threw it more than the person who received it, and a fighter who checks consistently makes the low kick an unprofitable trade.

Catching a body kick and sweeping the standing leg turns the opponent's own committed technique into a fall. The catch itself is a scoop: the arm on the side the kick arrives goes under the shin, the elbow tucks, and the leg is trapped against the ribs. From there the sweep takes the supporting leg out with a step-through or a kick to the ankle while pulling the trapped leg across.

The long guard extends the lead arm toward the opponent's face with the elbow slightly bent and the palm turned in, creating a physical frame between the two fighters. It is a defensive structure rather than a strike, and its job is to occupy the space an opponent needs in order to close.
