Hardest mate in 1 puzzles

Unfortunately, the position can be reached with white to move, and there is no mate for white.

But your position has given me some inspiration for something else. Again, add a white knight, then mate in 1 (now the knight can escape, but which square allows the mate in 1?):

this time add a white bishop then mate in 1

does it work?

SRY BUT IT IS MATE IN 3 MOVES

Add wBh8 and black to move and mate with Qxc1. But wQc1 can move too without affecting the parity. If wQc1 = wN and wNh2 = wB then the problem is solved, but then it is clear that a bishop promotion must have happened as there would be 3 white bishops.

the pieces are the distractions

Easy

this position is not mate's it's white winning.

Where did all Black's pieces come from?

Where did all White's pieces come from?

"i know mate in 1" but i need mate in 2

Correct, but every move including giving away the queen appears to win and there are at least three mates in four, none beginning exf7+. You don't even mate. How do you expect anyone to come up with your solution?

Apart from that, what on Earth does it have to do with the topic?

Also this position in #457 (beside being irrelevant to the topic and illegal) doesn't look remotely like a White win at the end of your moves - Black is two pieces and two pawns up - and if Black advances the f pawn first in the initial position it's a mate for Black in six moves.
