White to move and mate in 1.



Black has only two possible last moves: g7-g5 and f6xg5.

6 black pawns promoted on a white square. Suppose the f- and h-pawn didn't
promote. Then the other pawns needed 6 captures (a-pawn one, c-pawn one, e-pawn
one and g-pawn three)


why do you say the g-pawn would need 3 captures to promote on a white
square??

Because f1 and h1 are clearly unavailable as promotion square. How would the
bishop leave that square?
