A change in rhythm to delay or disrupt your opponent’s reaction time. You establish a certain rhythm so the opponent is used to it and then suddenly change it. It may be as simple as moving rather slowly and defensively for a while, and then suddenly attacking with a blitz of techniques. For example, for a few times use a jab-jab-cross, then use a jab-jab-hesitation-then the cross.
A movement, facial expression, or words that give gives the opponent a false sense of security. This type of deception is used mostly in street situations. Gestures may include looking or turning away from your opponent, cowering, acting scared, acting sick, pretending to be frail, or saying. "I'm leaving." Immediately after the gesture, you fiercely attack.
In magic's "Theory of False Solutions," the spectator is directed from one solution to another. When the spectator thinks he or she has the solution, the magician proves it wrong. By proving all the solutions wrong, the audience is left with no logical answer. When sparring, when the opponent thinks he or she has figured out your attack sequence, change the sequence a little. Then, when the opponent thinks he or she has figured out your new attack sequence, change the sequence a little. Etc. After a few cycles of this, the opponent will lose confidence in his or her ability to figure you out.
