Motto: "Die Schlacht"

K.Fabel schreibt: "vor 1910" (vermutlich das Datum einer Sekundärquelle). Da Sardotsch bereits 1898 gestorben ist, dürfte das Original-Publikationsdatum noch weiter in der Vergangenheit liegen.
Englischsprachige Problemzeitschriften schreiben den Vornamen des Komponisten übrigens "Nicholas" und lassen ihn Österreicher (aus Triest) sein, der zeitweise in Italien lebte.

Longest problem with both sides castling

Henrik Juel: Popeye 4.61 with 'opt thr 1' found no flaws (2020-11-04)
James Malcom: I've managed a small extension, so do not computer test this yet. (2020-11-04)
Olaf Jenkner: Semi-finished problems should not be published. (2020-11-05)
James Malcom: I agree-this was a severe lapse in my judgement. (2020-11-05)
A.Buchanan: I think you’re being too hard on yourself, James. It’s hard to know when a problem is “finished”. Unless a position is just thrown together for a discussion, I tend to wait another sleep cycle to see if any more ideas pop up. But it’s not the end of the world if an electronically published problem gets improved a couple of days after the first post (2020-11-05)
James Malcom: I had had the previous position for a while now, but only yesterday did I see how to improve it. And the new position has now been entered. There are definite duals in the sidelines, but there is a forward, main, defense plan for Black. (2020-11-05)

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)
