RULE
1. If the principal adverse Corps of Position are situated upon points of a given color, and if the principal Kindred Corps of Position are situated upon points not of the given color, then:
That army which has the more Corps of Evolution able to act against points of the given color, and the equality in Corps of Evolution able to act against points of the opposite color, has the relative advantage in Topography.
2. To utilize the relative advantage in Topography, construct a position in which the kindred Corps of Position necessary to be defended shall occupy a point upon the sub-geometric symbol of a kindred Corps of Evolution; which point shall be a Tactical Key of a True Strategetic Horizon of which the kindred Corps of Evolution is the Corps of the Centre and of which either the adverse King or an undefendable adverse piece is the second Tactical Key.
3. To neutralize the relative disadvantage in Topography, eliminate that adverse Corps d’armee which is able to act simultaneously by its geometric symbol against the principal Kindred Corps of Position upon a given color; and by its sub-geometric symbol against points of opposite color.
Perfection in Defensive Topography is attained whenever the ground occupied nullifies hostile advantages in Time, Organization, Mobility, Numbers and Position.
Perfection in Offensive Topography is attained whenever the ground occupied accentuates the kindred advantages in Time, Organization, Mobility, Numbers and Position.
