This is another pommel strike. And if you are quick, you will doubtless find the face uncovered. This can be done armoured and unarmoured. I have proven that four teeth will be knocked out of the mouth with such a play. And the sword can be wrapped around his neck if you want, as you will be shown in the play after this by the next scholar.
In the master play, both combatants have their right foot forward with the blades crossed in the middle. Similar to the 2nd scholar, lunge through with your left foot. At the same time, roll the handle of your sword in an arc under your opponents blade. Use the crossing point of the blades as the centre of the arc. This will provide you with cover as you cross to your opponents outside and enter the narrow play.
When the axis of your sword lines up with your opponents face, drive it forward, aiming just under the base of the nose. This strike works best if you visualise the sword handle as a dagger blade, and strike much as you would with a dagger. The power comes from the right hand, and your left only provides direction.
Fiores comment that four teeth will be knocked out is a very interesting detail. It is a very specific number, especially when coupled with the claim that he has proven this. We know from the books introduction that Fiore fought and won five formal duels. His statement here might imply that this was the play which finished one of them.
With both hands in position, and your momentum already moving to the outside of your opponent, wrapping your sword around their neck is a nice smooth way to continue from here.
