All warfare is based on deception. There is no place where espionage is not used. Offer the enemy bait to lure him.

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

If your enemy is superior, evade him

An army may be likened to water, for just as flowing water avoids the heights and hastens to the lowlands, so an army avoids strength and strikes weakness.

For them to perceive the advantage of defeating the enemy, they must also have their rewards.

The control of large numbers is possible, and like unto that of small numbers, if we subdivide them.

Know thy self, know thy enemy.
