I need 8 moves but that’s enough for me at the moment as I can’t figure out something quicker (and do not have the time for a longer search) now.
1. exf8N+, Kh8 [1. -, Bxf8? 2. Qf7+ mate next move]
2. Bxg7+, Kxg7
3. Re7+, Kf6/g6 [3. -, Kf8? 4. Qf7#, 3. -, Kh8 4. Qb2+ … 7. Qg7#]
4. Qf7+, Kg5
5. Qxf4+, Kh5 [5. -, Kg6? 6. Qg4#]
6. Re5+, Nf5 [6. -, Kg6? 7. Qf7#]
7. Qxf5+, Kh4
8. Qh5#
I am curios to see how mate in 6 works and so waiting for the other comments!? 🙂
