Many hours (spread over several days as I need breaks in case I get stuck and/or tired): I need to find an idea first but then also have to rearrange pieces again and again because either there is an unforeseen defence or other moves besides the intended one win, too. I have to experiement until only one single, clear and aesthetic solution remains.
Thank you! Do you (or maybe any of your friends) have an idea what could be the solution of my riddle? :)
It's hard and not so hard at the same time because you say it's forced mate in 6.
Unusual moves means a sacrifice. Promoting to both c8 and g8 is checkmate so how to deflect those two rooks was the first I noticed.
Answer is Qe6!
After that everything makes sense.
Then Qxg6! Removing one of the rooks and if Nxg7 then Qxd7 and mate should follow
Well, after 1. Qe6 Nd6 2. Qxg6 Nxg7 3. Qxd7 is impossible, but I guess you mean the correct move.
So what after 1. Qe6 Nf6?
Yes, now I'm getting confused. But yeah Rxf6! as Rook can't take f6 because of Qxd7#
Yes, I think you found the most important variations, congrats!
Soon I will add an example solution to this post.
How long did it take you to create this as there are so many variations I didn’t even see after Qe6
