Chess problem requiring an out of the box solution...

Do you see the mate in 1!?

Chess legend has this puzzle as a mate in 1, at first glance it looks good for white, with the threat of promotion,
but whatever he promotes the pawn to can be captured by the black king, simultaneously escaping the rook check…

However, at one point the rules didn’t specify that the piece you are promoting to has to be your own colour, leading to the astonishing promotion of the pawn on b8 to a black knight, which deprives the black king of it’s escape square
as it can’t capture its own piece… it’s checkmate in one.

Now unfortunately, it is illegal to promote to an enemy piece, making this mate in 1 impossible.
