Learning Fiore De Liberi

This pairing is interesting because of what Fiore says about di Fenestra: "And of covering and of wounding it is Master", while of Porta di Fero he says "This is also an excellent ward for exchanging the thrust, and thrusting yourself.". So the obvious thrust that di Findestra has will not work against Porta di Fero. Porta di Fero will easily be able to exchange the point or break the thrust.
Fiore also says "that it is always ready with malice and deceit. And of covering and of wounding it is Master." of Finestra, and this is the key to winning vs Porta di Fero, deceit. The key for Porta di Fero to win is to not be deceived into moving too early. While it may seem that Porta di Fero has the ability to exchange the points while the opponent is lying in di Finestra, this is not the case. Posta di Finestra is an instabile ward, and so any attempt at the point can easily be deceived.
If Posta di Finestra can advance traverse, while Porta di Fero's blade is too close to the line, Porta di Fero can easily be defeated here. Keeping the blade off the line for Porta di Fero is the opposite of what di Finestra must do. Finestra taking it's point off line removes the threat, and can give Porta di Fero an opportunity for it's own thrust.
However, in order for Finestra to make any cut other then a thrust, it's point must move off line. Combining that cut with footwork could deceive Porta di Fero into making a mistake. This is the game, di Finestra must deceive while Porta di Fero must be iron willed to not be deceived.
