Pretend inferiority and encourage his arrogance.

And therefore only the enlightened sovereign and the worthy general who are able to use the most intelligent people as agents are certain to achieve great things.

You can ensure the success of your attacks if you only attack places that are undefended. You can ensure the safety of your defense if you only hold positions that cannot be attacked. Therefore, that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.

If you fight with all your might, there is a chance of life; where as death is certain if you cling to your corner

Thus those skilled in war subdue the enemy's army without battle .... They conquer by strategy.

Attack is the secret of defense; defense is the planning of an attack.

Bring war material with you from home, but forage on the enemy... use the conquered foe to augment one's own strength.
