All war is deception.
Do not press an enemy at bay.
When you are ignorant of the enemy but know yourself, your chances of winning or losing are equal.
Use humility to make the enemy haughty. Tire them by flight. Cause division among them. When they are unprepared, attack and make your move when they do not expect it.
Concentrate your energy and hoard your strength.
It is according to the shapes that I lay the plans for victory, but the multitude does not comprehend this. Although everyone can see the outward aspects, none understands the way in which I have created victory.
