To pick your pocket, a pickpocket will bump into you hard enough that you feel a slight pain and are distracted enough that you do not notice that the pickpocket has picked your pocket. Therefore, to distract and confuse your sparring opponent, use a painful but quick less effective attack to one area while striking to another area with the finishing blow. A hard block to an opponent's attack may also distract enough so a finishing blow may be delivered.
Do not step into an incoming attack
Do not mistakenly step into an attack. It hurts. You may step inside or outside an attack if you have an effective counterattack planned.
Fakes and combinations
Use fakes to set up other attacks but make the fake realistic enough that the opponent must react to it. In fact, if the opponent does not react, the fake should be effective enough that it may score. Always attack in combinations of kicks and punches, high and low, left and right, up and down. Always keep you opponent off-guard and confused. Fakes should be used sparsely and only when there is an intention to attack.
