Henrik Juel: The motto is very apt
Why did you not frame the problem as a standard s#16, James? (2021-01-15)
James Malcom: It's probably because it was my first great leap at a long selfmate, and I didn't quite know all the conventions just yet. A color reversal should suffice for a C+ test. (2021-01-15)
SCHRECKE: C+, Gustav 4.1d, Brute Force (color reversal + rotation by 180 degrees) (2021-01-15)
A.Buchanan: In preserving this problem for future ages, I might tend to log the flipped version, and then record that the original was BTM, but up to you... :-) (2021-01-16)
