He Who Is Prudent And Lies In Wait For An Enemy

He will win who knows when to fight and when not to fight

If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.

Knowing the enemy enables you to take the offensive, knowing yourself enables you to stand on the defensive.

Attack him where he is unprepared, appear where you are not expected.

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 .

Thus the expert in battle moves the enemy, and is not moved by him.
