In the middle bind I will put your arm so that you will not make me any trouble. And if I want to slam you to the ground it is little bother to me, and you will not escape without difficulty.
As the 1st scholar, you are applying a ligadura mezana (middle bind). Start as the 1st Master with a hooking block to the wrist of your opponents attacking hand. Where the Master grabs and controls the hand, however, you apply the bind.
At the end of the hooking block, your forearm and upper arm form a 90 degree angle. Your elbow should be no further than a hand span from your ribs, and your hand should be level with your shoulder. This is structurally the strongest position for you to be in.
Without pausing, keep the momentum of your movement going. Move your hand in an anticlockwise circle, pivoting around the elbow to arrive back at the position just described. This should strip the weapon from your opponents hand. The picture shows the scholar mid way through this movement.
As much as possible, keep your elbow still, relative to your body. You will have to extend it a little to twist it over your opponents arm, however, if you overextend your elbow, it will weaken your structure, leaving you open to a counter. To keep the motion smooth, on the downward arc roll your hand palm down, and then roll it palm up on the upward arc.
As you are doing this, step up with your back foot, and then forward with your left, stepping into your opponent. This will push them off balance and maintain your advantage. As you lock your arm back into position and the bind takes effect, your opponent will arch their back and tip off balance to your left side. This will leave them exposed all down the front for you to deliver a strike.
Your most dangerous point in this technique is the moment in time captured in the drawing. The two players are structurally quite equal here. As the scholar, you hold the advantage by virtue of your momentum and capacity to return to a strong position. The whole play (essentially two consecutive hooking blocks) needs to be completed in a single smooth action.
