I actually tried to make a very nice mate in 12 however because there were too many variations I had to change it to this quite simplistic mate in 8 instead.
What does the mate in 12 look like? Generally, I consider anything longer than five moves to be (slightly too) ambitious to place on this application... but this one might have a chance
I am probably mistaken but it MAY have been a simmiler position to this. It might even be mate in eleven but when I think about it, even that is not very difficult.
