The original problem:

If white first to move then Nf7 is mate. If not then draw

:

I think this is solution that arrives at previous puzzle:):

What's the answer?

You're sure it's not a fool's errand?

???

Nice try but 1.Nd5 only leads to a draw. Try again.

Wow, I have no idea, lol

My deear friend let me ask u if u ask yourself what will do white on move 11?

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

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

White will capture the black queen, of course.

Black to move and lose.

There is no way for black to save that game.

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.

Wow, that's so simple :P

Well done Kacparov... did you work it out yourself?

Cool :-)

Thanks!
