Just to confirm...
Is difference between the two simply that the glance strike (schielhau) steps with only the right foot while the thwarter (zwerch) steps completely to the opponent's left?
The "step fully" part with the glance strike kinda threw me off a bit since the zwerch says "strike to close by stepping full to his left side."
These can be found in Joachim Meyer on longsword, pages 11 and 12.
Thanks!
