From the grip made by the scholar before me, I can feel the sword has fallen to the ground. It is no lie to say that I can injure you greatly.
Having completed the play of the 16th scholar, keep moving so as to not lose any momentum. As your body weight moves forward, put all your weight onto your left foot. Pivot 180 degrees on the ball of your left foot.
As you do so, pull your right foot back, so that your feet are together. You will be facing the same direction as your opponent. Bend your knees and push your left hip under their right, so stealing their centre. With your left arm, try to catch your opponent as high up the forearms as possible, and lock your left elbow down against your ribs with your forearm across your belt.
You should be right underneath your opponent at this stage. Everything momentarily contracts down into your own core. You want to lift your opponents hips up and pull their elbows down into your centre, forcing them off balance. Do not bend over. Make sure you keep your back upright. As you drop your weight, your own sword hand will drop as well. Ensure the handle of your sword crosses the blade of your opponents sword just above the hilt.
This contraction is the crux of the two plays. You will need to practice it slowly, smoothly and often in order to be able to be able to do it at speed with confidence. It is in many ways mechanically the same as a throw, and relies on timing and flow more than strength.
Continuing on, drop your right foot behind you and keep pivoting on the balls of your feet. In total, you will have spun in almost a complete circle, and be facing roughly the same direction you started in. The whole thing has the sensation of spinning through your opponent like a whirlwind, and catching them up in your movement. As you pivot on your feet, scoop your hand down and then up again to posta de fenestra.
Your opponent will have their elbows pinned together and will be swept along as you spin past them. As their arms are locked shut, their hands will tend to pop open. The scoop of your sword will rip their sword from their grasp and fling it dramatically behind you somewhere. You should find yourself more or less as depicted.
Drop the tip of your sword to the pit of your opponents throat and push.
