When I come to the guard in the narrow cover, if I cannot wound with a cut, I use the point. If I cannot injure with either of these, I will strike with the cross guards or pommel. This is done according to what I decide. And when I am in the narrow play, and the player believes I want to use the sword, I am going to grapple if it gives me the advantage. And if not, I am going to strike him in the face with the cross guards as I said before.
Having made the master cover, the scholar needs to flow on to another technique. When cutting and stabbing are not options, pommel striking and grapping come under consideration. In the end, the 7th scholar opts for a cross guard strike.
The master cover has swept your opponents sword off to your right side. The very close range and the mechanics of the play mean that it is safe to move in false time. Keep your left hand reasonably still in space and step your right foot past it. As your toes touch the ground, begin the strike with your right hand. It will feel something like you are punching your opponent in the forehead. Pivot the blade around the left hand and make contact as your weight sinks onto your front foot.
There is no need to try and drive this technique through your opponent. Stop the sword at vertical and then transition to something else. Eyes are particulalry vulnerable to stabbing attacks. At the very least, your opponent will be momentarily blinded, allowing you a free shot. In a perfect hit, it is possible to drive the cross guard straight through the eyeball and socket and into the brain, causing your opponent to collapse dead at your feet. Most likely is they will suffer a fractured eye socket and be unable to either see or continue fighting.
