As you can see, the scholar who came before me wounded the player in the face with the cross guard of his sword, and I can readily wound him with the pommel in his face as you see below.
This play can be used either as an alternative to, or a continuation of, the 7th scholar of sword in armour. You have already used the master play to cover your opponents attack and close the distance between you. Take a second step with your right foot to move in to very close range. Cover yourself with your sword as you step through, using it to jam your opponents movement. At this point, you can make the play of the 7th scholar if the opportunity is there. Whether you make that play or not, continue your movement so that the axis of your sword lines straight up at your opponents face, and your right elbow points over their shoulder as shown.
Keeping your elbow still, pivot your hips clockwise and swing your forearm up into your opponents face. It should feel a lot like making an upwardly angled roverso strike with a dagger.
This will cause a great deal of damage against an opponent with an open faced helmet. Even striking against a visor or bevor will, at the very least, disrupt your opponents balance and win you the initiative to make the next move. This play can smoothly transition to the 9th scholar to throw your opponent.
