“He will win who knows when to fight and when not to fight; who handles both superior and inferior forces; whose army is of one spirit; who is prepared and waits for the unprepared; who has capacity and is not interfered with.”

The five conditions are repeatable and learnable; master them and wins stop being lucky.
Chapter 3 closes its argument with the checklist of who wins: the one who knows when to fight and when not to; who handles both superior and inferior forces; whose army is of one spirit; who is prepared and waits for the unprepared; who has capacity and is not interfered with. Five conditions, each learnable — the chapter’s final claim is that victory is a discipline, not a gift.
A startup scores itself honestly: strong on timing (knows when to fight), strong on spirit, mediocre on preparation, weak on handling inferior forces (it bungles the small competitors it dismisses), and bleeding on the fifth — a board that interferes weekly. The scorecard’s value is not the diagnosis but the ordering: the board problem caps everything else, and no amount of spirit compensates for condition five being broken.
The five are not equally weighted at all times — that is the point of scoring rather than reciting them. Which one binds changes with the season: a young team’s binder is usually preparation; a mature one’s is interference or spirit. The discipline is re-scoring when the situation changes, not laminating last quarter’s answer.
