The Problemist problem. Mate in 24 moves

This is The Problemist chess problem. Hope you will enjoy it! :)

Hints for White: Only one piece can move, if you move any other you will let the king escape or check your own king.

Hints for Black: No piece can move except for the pawns, else the checkmate will be shortened.

After seeing enough compositions by Blathy, it's clear what the first 20 or so moves will be. The end I had to think about a wee bit. Too bad about the dual on the very last move. (24.Bc6#)

The last move can be either by moving 24.Bc6# which was the main square for the bishop to find and the other is the pawn 24.b3#. If black does everything right he can prolong the checkmate to a maximum of 24 moves but it's pretty hopeless for black either way.

I'm pretty sure the last moves must be 22... Nd2+ 23. Bxd2 23... e1=Q 24. Bc6#. No dual.

Why must Black play 22...Nd2+? Seems 22...Nxe5+ is a defense as well.

Black isn't forced to play 22...Nd2+, but that must be the move in the puzzle to have only one correct continuation.

That helps with the chess.com viewer but not with chess problem standards. :)

This is not a problem that I made. It was made from a person in a newspaper called The Problemist. I found it in a youtube video that was explaining this problem. Here is the link to the video if you want to see more about it: https://www.youtube.com/watch?v=1BuLsK2o6XM

But then white does 7. Bb4 and unstoppable checkmate with 8. b3#.

That's why the bishop shouldn't move at all.
