The Art of War is self-explanatory

Unless you enter the tiger's lair, you cannot get hold of the tiger's cub's.

With regard to ground of this nature, be before the enemy in occupying the raised and sunny spots, and carefully guard your line of supplies. Then you will be able to fight with advantage.

Pretend to be weak, so your enemy may grow arrogant.

Do not swallow bait offered by the enemy. Do not interfere with an army that is returning home.

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

Use humility to make the enemy haughty. Tire them by flight. Cause division among them. When they are unprepared, attack and make your move when they do not expect it.
