Ponder and deliberate before you make a move.

When I have won a victory I do not repeat my tactics but respond to circumstances in an infinite variety of ways.

All men can see these tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved.

Do not press an enemy at bay. Prince Fu Ch'ai said: "Wild beasts, when at bay, fight desperately. How much more is this true of men! If they know there is no alternative, they will fight to the death.

Factors in the art of warfare are: First, calculations; second, quantities; third, logistics; fourth, the balance of power; and fifth, the possibility of victory is based on the balance of power.

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

Appear weak when you are strong, and strong when you are weak.
