An advantage is a relationship.
Reading weakness and strength as changing conditions, rather than permanent qualities.
Editorial interpretation for review. Separate from the creator's translation.
It is tempting to call one side strong and the other weak, then treat those labels as an explanation. Chapter 6 gives us a reason to look more closely: at the place, the moment, and the distribution of what each side has.
Start with a place, not a total
In the passage beginning 我专为一，敌分为十, the text describes one side concentrating while the other is divided across ten places. The comparison is local. A total tells us how much exists; a distribution tells us where it can be used.
This distinction is easy to miss when reading a memorable sentence in isolation. Read the surrounding discussion of making the other side defend multiple locations. The distribution is part of the problem, not a free advantage that appears by itself.
A diagram makes the assumption visible
Our exploration begins with 60 units on one side and 90 on the other. If the second side is evenly divided across three fronts, each front receives 30 units. Concentrating 70% of the first side's resources puts 42 units at one front: a local ratio of 1.4 to 1.
Nothing was added. The other two fronts now have only 9 units each. Concentration changes both the place you strengthen and the places you leave less supported. Move the controls and examine both effects.
The conditions do not stand still
The model holds the opposing allocation fixed. The text does not give us permission to expect a real opponent to remain still. Information, travel time, coordination, and responses may change the situation.
Later in the chapter, water is used to discuss changing form. This is a useful check on our interpretation: a successful arrangement is not necessarily a reusable recipe. Ask what has changed before reusing it.
If the other side could immediately move resources to your chosen front, which part of the example would stop working?
