W: 1. c8=Q 2. Qg8 3. Bd5 (Rg8) #

* White and Black side must make the consecutive moves indicated by the formula: here it is B: 7 + 2#: 7; but nothing is impossible, in this condition (e.g.: B1, W5, B56, W2#).
** On moving, a piece leaves behind a Pawn of opposite color on its departure square. The rule does not apply to Pawns, or to pieces moving from the 1st or 8th rank, nor does it apply if there are 8 Pawns of that color already on the board. If White plays with a neutral, half-neutral, etc. piece, it will leaves behind an orthodox (not neutral, half-neutral, etc.) black Pawn, while Black playing with neutral, half-neutral, etc. piece will leave behind a white Pawn.
*** Every man is decomposable as follows: Q=R+F; R=F+P; F=PP. The decomposition is actuated with the mere removal of one of the components: the other remains on the square. No suspended Pawns (i.e. in ranks 1 or 8) allowed.
