Regarded as a Chessic Corps d’armee the Queen marches and attacks as
infantry, cavalry and artillery.
Either, neither, or both Queens may be present in any given Strategetic
Horizon; and whenever present the effect of her co-operation
mathematically is outlined, viz.:
At her maximum of efficiency the Queen occupies the common vertex of one
or more unequal triangles, whose aggregate area is from a minimum of 21
to a maximum of 27 points. Her offensive power is equally valid against
all of these points; but her defensive power is valid for the support
from a minimum of one point to a maximum of five points.
