Hardest Mate In 1 Puzzle Ever.

Why can't the pawn be promoted to d8?

#7 nice! Took way too long for me!

There are two mates. Q A3 if white is to move; Q H5 if black is to move...

Good puzzle! I think Lichess should add difficult mate-in-1 or mate-in-2 puzzles to its tactics training.

In an actual game, I would've played Qxe5 (Be6 Qexe6#). Still a mate in 2!

Why on earth would you take a harder route???

I spent 6 minutes on it. What game is it from? I suggest to play this games towards such position, so captchas (which are taken from very recent games) will consist of such mates in 1. We will make everyone crazy, who wants to post something.

It is a composed position by Leonid Kubbel. I gave another one in post #7 which is my composition.

And another of mine, yet again white to mate in 1:
