Weak Points and Strong
WEAK POINTS AND STRONG [Chang Yu attempts to explain the sequence of chapters as follows: "Chapter IV, on Tactical Dispositions, treated of the offensive and the defensive; chapter V, on Energy, dealt with direct and indirect methods. The good general acquaints himself first with the theory of attack and defence, and then turns his attention to direct and indirect methods. He studies the art of varying and combining these two methods before proceeding to the subject of weak and strong points. For the use of direct or indirect methods arises out of attack and defence, and the perception of weak…

Key Quotes & Analysis
"Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle, will arrive exhausted."
Context: Opening contrast between the commander who chooses timing and the one who is forced to react
First arrival is rest; forced march is exhaustion before contact. Initiative in time and place is already a form of strength.
In Today's Words:
Whoever reaches the field first waits fresh; whoever rushes there second arrives exhausted, Sun Tzu opens, and that gap shows up everywhere. In hiring, sales, or product launches, the team that picks timing and terrain early sets the terms while rivals scramble to respond on unfavorable, costly ground they never chose.
"Therefore the clever combatant imposes his will on the enemy, but does not allow the enemy’s will to be imposed on him."
Context: Immediate follow-up on initiative after the first-in-field advantage
The clever combatant sets the agenda. Once you are answering the enemy's prompts, you are fighting on his schedule and his ground.
In Today's Words:
The clever combatant imposes his will and refuses to have the enemy's will imposed on him, Sun Tzu says, which is the difference between setting and answering the agenda. If every release, salary negotiation, or public debate is a reaction to their move, you are already conceding timing, framing, and what counts as winning.
"Hence that general is skilful in attack whose opponent does not know what to defend; and he is skilful in defence whose opponent does not know what to attack."
Context: Middle section on attacking undefended points and keeping dispositions concealed
Sun Tzu compresses the whole art of war into one line: create uncertainty about where force will land, and the enemy must divide or mis-guard.
In Today's Words:
The skilful attacker is the one whose opponent does not know what to defend, Sun Tzu says, and the skilful defender is the one whose opponent does not know what to attack. Unpredictable entry points and concealed roadmaps force bigger rivals to spread attention until your push hits an undefended seam.
"So in war, the way is to avoid what is strong and to strike at what is weak."
Context: Closing water metaphor after tactics compared to water flowing downhill
Like water, strategy succeeds by finding low resistance. Strength against strength is the amateur's mistake; the master flows to the gap.
In Today's Words:
In war the way is to avoid what is strong and strike what is weak, Sun Tzu closes, like water that runs from high ground toward the lowest path. Do not match a competitor's flagship feature or legal team head on; enter the neglected segment, broken workflow, or support gap they treat as too small to defend.
Thematic Threads
Adaptability
In This Chapter
The formlessness of water as the model for strategy
Development
Adaptability becomes a recurring theme—no fixed tactics
In Your Life:
Are you flexible enough to change approach when circumstances change?
Deception
In This Chapter
Being 'formless' prevents the enemy from targeting you
Development
Unpredictability as a form of protection
In Your Life:
Are you too predictable? Could competitors easily anticipate your next move?
You now have the context. Time to form your own thoughts.
Discussion Questions
This is not a test. Five prompts guide you through the chapter, from how it opens to how it closes, so you notice context and rhythm rather than facts to memorize. Sit with each question in your own words. When you see "One way to read it," treat it as a starting point, not the only answer.
- 1
What does Sun Tzu mean by attacking weak points and avoiding strength?
analysis • surfaceOne way to read it
Engage where the opponent is unprepared or thin, refuse fights on their strongest ground.
- 2
Why does he compare strategy to water?
analysis • mediumOne way to read it
Water adapts to terrain; effective competitors shift shape and target as conditions change.
- 3
What competitor weakness could you exploit that you currently ignore?
application • mediumOne way to read it
Slow support, legacy tech, neglected segment, or talent drain in a unit they assume is secure.
- 4
Why do teams insist on head-to-head fights they are likely to lose?
reflection • deepOne way to read it
Ego, metric envy, and mistaking bravery for strategy when avoidance or repositioning would win.
- 5
How can you become more 'formless' without losing internal clarity?
application • deepOne way to read it
Vary timing and channels while keeping a private map of priorities so unpredictability serves purpose.
Critical Thinking Exercise
The Weakness Map
Map competitor weaknesses in your field.
Consider:
- •Where do they underperform? What do they do poorly?
- •What segments do they neglect? What needs do they ignore?
- •Where are they slow, expensive, or inflexible?
- •Which of these weaknesses could you attack?
Journaling Prompt
Describe how you could 'be like water' in a current competitive situation—flowing around strength to attack weakness.

Chapter 7: Maneuvering
Chapter VII tackles maneuvering: turning the devious into the direct, keeping supply lines intact, and using signals so large forces move as one. Execution bridges strategy and results.
