Everything is stupid lately, and when everything is stupid also swordsmanship is stupid. I do not feel like I am going anywhere, which contradictorily makes me put in less effort, which obviously does not help much, and, well. You get the point.
This picture shows a strike to the chest after a parry over the dagger(1).
You are in extended terza with the dagger over the wrist.
He is in low quarta with his sword withdrawn(2) and his dagger extended high.
Begin to feint above his dagger(3), remaining in terza and keeping your dagger at the wrist. He will parry upwards with his dagger and will attempt to strike on you the same tempo, in quarta or in seconda.
When he does, disengage under(4), parry his attack(5) at the same time, and strike him in quarta.
(1) Don't you wish he'd say at these points whose dagger it is, instead of having you figure it out from the context?
(2) I have to say it looks like I was correct when about the dagger position pictures I said that what strikes me as the common denominator for the positions beyond the solo sword is how the arm is withdrawn. I also have to say it is not clear to me at all what the benefit of that withdrawing is supposed to be.
(3) Oh! Thanks, Mr CF.
(4) Under his dagger, one assumes. Then again, the picture shows the attackers sword below everything else.
(5) Picture shows the parry to happen with your dagger, not with the sword.
