good man
Can you Solve this Puzzle ... I don't think
You cannot legally promot to a black piece if you are white. Sorry
it says "One very Important role : the Pawn can promote to any Chess Pieces ... any one ....remember ... any one"

I don't see the problem with 1. b8=Q+ Kxb8 2. Qd8++
The problem is that you took 2 moves when the stipulation was 1.
White to move any mate in one ..... Do not get angry .... just think and think and think .... In the end, you can regsin
One very Important role : the Pawn can promote to any Chess Pieces ... any one .... remember ... any one
