A closing sequence from the sen no sen tradition - moving at the same instant the opponent decides to move, so their strike lands in the space you just left.
Cross the danger zone against a puncher and secure a controlling tie.
A striker owns the outside. Cross their danger zone in one continuous motion: no stutter step, no test punch.
Time your entry to their exhale. On the exhale, their next combination is a beat away, and that beat is your window. Post your lead hand high, palm out, covering the temple and the jab line.
Enter behind the shield, chin tucked, hips low. Attach at the elbow, not the wrist. Wrists slip; elbows control the shoulder, and the shoulder controls the punch.
