{There are essentially three candidate moves, the "a" pawn push,
the push of the "g" pawn and the activation of the white king. All fail, but it is necessary
play a "stupid" move ("mazette sees check, makes check!") after which, depending on
where the Black King is placed, the three candidate moves occur.
White's plan is to force Black's Bishop to sacrifice himself against a
pawn, but he must take care that the square c2 (which his own bishop must
control) is on the same diagonal as his remaining pawn, to avoid that
wB is deflected by the c3-pawn. They must therefore allow the sacrifice of the
bB against the "g" pawn only if the other one has remained on a4.} 1. Bb3+ $3 {This check
is the only winning plan, preventing the coordination of the two black figures.
It could be made elsewhere, but the other moves are just
wastes of time, as the heptocephalic monster confirms.} (1. a5 $2 {
(allows for a change of function: the bK takes care of the now weakened 'a' pawn
