first series : Takedown on one leg entry
The partner undertakes its activities with a direct kick from the front leg, followed by a roundhouse kick to the body. Yukinobu Shimabukuro reacts initially, controlling and blocking with its folded back in the first leg kick. The second attack, he immediately makes a small withdrawal back and grabbed the leg. It uses the inertia of a second side and the input displacement for folding the leg and perform a turning. This control facilitates takedown of his partner who is belly down. YukinobuShimabukuro continues to hold the leg and finalizes with a high heel strikes down.
second series : Absorption of the path for deflecting the attack, followed by a scanning and a key
Yukinobu Shimabukuro control the first leg with a simultaneous attack blocking. On the second kick, it absorbs a total withdrawal and the opportunity to deflect while grasping the handle trajectory. The partner is reflected back and is destabilized. Yukinobu Shimabukuro continues its work with internal scanning. Once on the ground, it performs an armbar and ends with a hammer.
