Posta di Bicorno

Posta di Bicorno, meaning "Two-horned Guard", is a posta instabile featured briefly in the beginner's plays. It is similar to Posta Breve in that is entirely a thrusting position, but the blade is held with the edges facing horizontally rather than vertically, adding (almost ironically, it would seem) more stability in thrusting than Posta Breve, even though the former is classed as instabile and the latter is stabile.
