excerpt from:
Sun Tzu: The Art Of War
I. Laying plans
verse 17: According as circumstances are favorable, one should modify one's plans.
verse 18: All warfare is based on deception.
verse 19: Hence, when able to attack, we must seem unable; when using our forces,
we must seem inactive; when we are near, we must make the enemy believe we are far
away; when far away, we must make him believe we are near.
III. Attack By Strategem
verse 2: …to fight and conquer in all your battles is not supreme excellence, supreme
excellence consists in breaking the enemy's resistance without fighting.
verse 3: Thus the highest form of generalship is to balk the enemy's plans; the next
best is to prevent the junction of the enemy's forces; the next in order is to attack the
enemy's army in the field; and the worst policy of all is to besiege walled cities.
