“Be where your enemy is not.”

“To know your Enemy, you must become your Enemy.”

“Know the enemy and know yourself; in a hundred battles you will never be in peril. When you are ignorant of the enemy, but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and yourself, you are certain in every battle to be in peril.”

“If ignorant both of your enemy and yourself, you are certain to be in peril.”

“If you wait by the river long enough, the bodies of your enemies will float by.”

“The spot where we intend to fight must not be made known; for then the enemy will have to prepare against a possible attack at several different points;”

“If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected .”
