少打无谓之仗 does not end when you decide to enter. After 始计 and after 作战, the next judgment is 谋攻 — Attack by Stratagem. The question is no longer only “is the ground clear?” It is “must force meet force, or can the aim complete without a clash?”
Sun Tzu’s order is blunt. 上兵伐谋，其次伐交，其次伐兵，其下攻城. Highest: attack the plan. Next: alliances and relationships. Next: the army. Lowest: walls and siege. The highest good is 不战而屈人之兵 — complete the aim without fighting. Whole resolution outranks breaking. On sun-tzu.ai this is a stay-cheap checklist, not a script for pressing a counterpart: change the plan and the relationship before you spend force.
Read the live chapter after this note: Attack by Stratagem.
What 谋攻 actually asks
The chapter opens with completeness. 全国为上，破国次之. Taking a state whole is better than breaking it. Winning a hundred battles is not the highest excellence; breaking resistance without fighting is.
That line is easy to quote and hard to use. Before you mobilise, quote, or argue, ask whether the other room’s plan is the real object. If their plan is wrong, a cheap answer only funds the wrong plan. If the plan can be rewritten, force never has to leave the yard.
sun-tzu.ai keeps four moves: 先察, 先谋, 再动, 复盘 — look first, plan first, move only with a stop date, then write three sentences. 谋攻 is the middle of that loop. 始计 decides whether to enter. 作战 counts the burn once you have entered. 谋攻 asks whether the clash itself is necessary. Skip it, and you spend people, lead time, and goodwill on a fight a clearer window could have dissolved.
The preference order, written so you can use it
Do not treat the four levels as poetry. Write one line for each on the job in front of you. If you jump to the bottom without writing the top two, you are already in siege mode.
伐谋 — attack the plan. What assumption, scope, or operating window is driving the collision? Can it be named, checked, and rewritten so both sides keep the next cycle intact? Fighting on price while the plan stays fog is not 伐谋. Changing the plan is the first move.
伐交 — alliances and relationships. Who else has to agree for the job to stay whole? If one relationship can carry the constraint into the room, you do not need a letter that starts a fight. 伐交 is not vanity networking. It is using the path that already exists so force does not have to invent one.
伐兵 — the army. Only after plan and relationship have been tried. Force here is mobilisation: a rush quote, a discount war, a legal letter, a public post meant to pressure, a crew sent before the window is written. Sometimes force is required. The chapter ranks it third.
攻城 — walls and siege. Worst. Three months for shields, three more for the rampart, then anger sends men up the wall and a third are lost while the city still stands. In industrial work the siege is the long tender you cannot exit, the price war that empties trust, the lawsuit that “wins” a number and loses the next five years. Use it only when nothing cheaper remains.
Those who keep the preference order finish with force intact. Those who skip to siege spend force and still leave the aim broken.
A fight that should have been a plan rewrite
An inquiry arrived that looked clean: size, quantity, delivery wish. The first instinct in many rooms is to answer fast and fight on price if another number appears. That is 伐兵 before 伐谋.
We did not open with a number. We asked for the operating window — the facts that decide whether the job is even the same job. Some lines filled in. One did not. That missing line was the plan. Answering into fog would have been a small siege: invent a figure, watch another invent a lower one, then “win” work whose ground was never named.
伐谋 here meant changing the request from “answer now” to “window first.” 伐交 meant putting the ask to the person who owns the facts, not only the person chasing a date. Only after those two moves would 伐兵 — a real answer with a real stop date — make sense. If the window never clears, staying out is still 始计. See also: Do not enter when five factors are unclear.
How to write the four lines before you spend
Open a blank page. Title it with the object, not with your hope of winning.
- Object: the inquiry, the dispute, the meeting, the well.
- Goal: the change that would make the next cycle better — not “beat them” and not “close this week.”
- Resistance: the real block. Often an unwritten window, a missing signer, or a false assumption about what the other room needs.
- Four lines: 伐谋, 伐交, 伐兵, 攻城. One sentence each.
- Judgment: which level are you on, and why. Verify only the next cheaper path.
If you cannot write 伐谋 and 伐交 in ten minutes, you do not need a fiercer answer yet. You need to admit you are about to spend force on a guess. 知彼知己，百战不殆 — know them and know yourself. Knowing here is not spying for sport. It is refusing to attack a fog you refused to name. Laying Plans is the stay-out checklist that belongs before this one. If the burn has already started, Waging War asks for the stop date.
Do not turn the four levels into a scorecard for humiliating the other room. 谋攻 is not a license to manipulate. Keep force whole so the next cycle still has people left.
What “without fighting” is not
不战而屈人之兵 is not passivity, and it is not a pose. If the plan cannot change, the relationship cannot carry the load, and the aim is still worth the cost, you may have to use force — with a stop date, with 法 that will hold, with a review written before anger arrives. The chapter calls siege the lowest path, not an illegal one. The calamity is the commander who cannot hold his anger and sends the wall climb too early.
Without fighting is not “win by deception in the sales deck.” This site does not teach you how to press people. It asks whether the clash is necessary, and what would make the next cycle better.
Read the chapter, then stop
Go to Attack by Stratagem. Write the four lines for the job in front of you. If 伐谋 and 伐交 are blank, do not spend force yet.

谋攻 is the chapter that saves force after you have already decided the ground is worth standing on. The kindness to people nearby, and to people under heaven, is the same move: change the plan and the relationship before you spend the army.
