Our first interpretation looks like a form of nachreisen (chasing/following after) where our opponent attempts to leave the bind and we pursue.
Since recording our video on plate 7 (see below) we’ve learned a bit more about the play. Essentially this is a game of leverage.
In terms of power, both fencers start by pushing to their respective lefts. Our fencer needs to be in a slightly stronger bind so that his opponent doesn’t have an easy thrust. While maintaining light to moderate pressure, our fencer slides his sword up towards his opponent’s weak (top half of the sword). Not all the way, just enough that he can then apply then downwards pressure.
This is where our opponent foils himself. If he continues to push inwards while our fencers pushes down, they’ll eventually reach an inflection point. After which, the opponent will unwittingly be helping our fencer sweep his blade down.
This works surprisingly well even when the opponent is sensuously resisting because his direction of force is nearly 90 degrees to ours. We just need to have enough power to get past the inflection point, which can be found using leverage rather then brute strength.
