@greatwolf, you saved my chess problem!
Actually when I composed it I only had one solution in mind, the one which you found! And yes, I thought I had checked it well enough. However, when @juanmi96 posted his idea, I suddenly thought "Damn, there is a second solution, but I have to accept that, and it looks nice, too!"
(I didn't check it thoroughly enough to verify it before I declared his solution as 'correct', too, neither by 'biobrain' nor by chess software - sorry for the confusion caused. :-) )
But you are completely right: After 1.Kf8 f6 black wins, and to be honest, I am happy that my little chess problem has one solution only ...
