All warfare is based on deception. Pretend inferiority and encourage his arrogance. Even though you are competent, appear to be incompetent. Though effective, appear to be ineffective.

To a surrounded enemy, you must leave a way of escape. Build your opponent a golden bridge to retreat across.

Speed is the essence of war. Take advantage of the enemy's unpreparedness; travel by unexpected routes and strike him where he has taken no precautions.

If your opponent is of choleric temperament, seek to irritate him.

-Sun Tzu
