If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.

Thus the skilful general conducts his army just as though he were leading a single man, willy-nilly, by the hand.

The skilful employer of men will employ the wise man, the brave man, the covetous man, and the stupid man.

If you are far from the enemy, make him believe you are near.

The expert in battle seeks his victory from strategic advantage and does not demand it from his men.

One who sets the entire army in motion to chase an advantage will not attain it.

If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, 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.
