Using a deceit presupposes contempt for your enemy - and overconfidence is a path to sure death. However, it is also necessary to know of the advantages and disadvantages of deceits, so that one can see through them more clearly. Also deceits and false blows are part of the game of skirmishing for exercise and pastime. False attack - drawing a parry or dodge, followed by striking at the newly open area by either disengaging the first weapon or by striking with a weapon in the other hand. Misdirection - as a card trickster will make a grand gesture with his right hand to draw the eye while subtlety exchanging cards with the left, so it is possible to distract in one direction while striking in the other.
Any false attack presupposes a predictable reaction from the opponent.
Through careful observation, you will be better able to judge how your opponent will react. My general advice regarding falses is, if you start with the intention to false, if your opponent does not ward you must be ready to make your false true, and hit home instantly. With the Single Sword falses are almost infinite - thrust, cut, high low, within , without. The blow is different from the false only by intent. It is a common error to strive to encounter the weapon, and focus on that objective without regard to time or advantage.
