Interesting problem. It's definitely possible to get a safe promotion, but that seems to always lead to a drawn game.
An original puzzle


Thats an interesting safe promotion! Using a pin to keep the queen away. The ones I found just restricted her access

Brilliant, you've done it.
It sure looks simple now, doesn't it? but all of us couldn't do it. All it took to lift the stalemate defence was a small adjustment of the pieces.
I'm certainly pleased with this solution.

i know solution its so easy
you said its black move and white wins the game:
i dont know who introduce this puzzle to you but that is not true
black should be foolish to force white do this checkmate.black has 1 queen that can check white king forever or sacrifice his queen to opponent,s pawn
perhaps solution is mate black with 1 knight and 1 king!!!!!!
The original problem:
I think this is solution that arrives at previous puzzle:):
Nice try but 1.Nd5 only leads to a draw. Try again.
My deear friend let me ask u if u ask yourself what will do white on move 11?
