Regarded as a Chessic Corps d’armee, the Pawn at its normal post marches
as infantry and cavalry. Should an adverse corps, however, take post
within the kindred side of the Chessboard; that Pawn upon whose altitude
the adverse Piece appears, at once loses its equestrian attributes and
marches and attacks exclusively as infantry.
Located at any other point than at its normal post, the Pawn is composed
exclusively of infantry and never acts either as cavalry or artillery.
From one to eight Pawns may be present in any Strategetic Horizon;
and whenever present the effect of its co-operation mathematically is
outlined as follows:
At its maximum of efficiency the Pawn occupies the vertex of a triangle
of two points. Its offensive power is equally valid against both of these
points; but its defensive power is valid for the support of only one
point.
