Summary

This chapter is about attack selection and adaptability. The skilled strategist chooses where and when to engage, attacking weaknesses rather than strengths. They impose their will rather than reacting to the enemy's.

Sun Tzu emphasizes speed and first-mover positioning. Whoever arrives first controls the terrain; whoever arrives second is already at disadvantage. The skilled general 'marches swiftly to places where he is not expected.'

The chapter's most famous passage describes water: 'Water shapes its course according to the nature of the ground over which it flows.' The successful strategist is similarly adaptable, formless, responding to circumstances rather than following rigid plans. There are no fixed tactics; everything depends on reading and responding to the situation.

Why This Matters

Strategic Attack Selection

Most people lose by fighting where the opponent is strongest because that is where attention already lives. Sun Tzu says arrive first and impose your will, then attack undefended points so the enemy cannot guess what to guard, like water that avoids heights and strikes low ground.

Map where rivals are stretched thin, refuse their chosen battlefield, and adapt your next move to what is actually in front of you, not last week's plan.

Coming Up in Chapter 7

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 This chapter addresses the complexities of moving forces into position, the operational level between strategy and tactics. Maneuvering is difficult because it requires 'turning the devious into the direct', making complex movements appear simple to the enemy..

Winning Without Fighting

The clever combatant imposes his will on the enemy but does not allow the enemy's will to be imposed on him. Like water finding the path of least resistance, the skilled strategist attacks weakness and avoids strength. Be formless—adapt to circumstances rather than following rigid plans.

Key Insight

Don't compete where competitors are strongest. Find the gap, the weakness, the undefended point. Flow around the rocks rather than fighting them.

“Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards.”

Full analysis

Varying Tactics Under Pressure

Weak Points and Strong compares tactics to water, which runs from high places and hastens downward. The skilled commander imposes a will on the situation instead of accepting the form the opponent prefers. Be formless enough that yesterday's successful method is not tomorrow's habit.

Key Insight

Repeating last quarter's winning move is how a strength becomes a tell. Ask where the other side is not defending, then move there, even if the last success happened somewhere else.

“Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards.”

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…

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?

Journaling Prompt
