All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

[Use when]

Someone is optimizing their own strength and ignoring what the other side believes about them.

[Why it matters]

This is the book's master key, stated in chapter one before a single tactic. Everything in the thirteen chapters is downstream of it: the feigned disorder, the baits, the secrecy, the spies. The point is not that lying is clever; it is that the enemy's decisions are made from his picture of you, so the picture is the battlefield. Control what he believes and you control what he does, before a blow is landed. Hold out baits to entice him, feign disorder and crush him, pretend to be weak that he may grow arrogant. The fight starts in his head.
