After the shot, the position is draw (database).
But if you put the man 35 at 40, then you have a winning position.

I like this very much! It is very sharp to see this. At first the engine gives a win, but after more time it slowly drops to a draw. We will change it so thank you very much!

Btw: The fact that the solution ends in a draw in itself is not wrong. In some situations the best move is an only defense not to lose. Those puzzles could get in. But here, this is not the case. Black could play different moves that are ok.

You're welcome :)
