Lösungsbesprechung: “Der Autor erweitert eine lang bekannte Mattführung durch ein frühes, überraschendes L-Opfer. Hat seine Daseinsberechtigung, doch eigentlich müsste es heißen: ‚nach C. F. Jaenisch‘, P1171799 von 1837!” [BK] Die Ursprungsidee ist sogar noch älter: “Die zweitlängste Darstellung des 1-Springer-Idealmatts in der Ecke. Es gibt viele Bearbeitungen dieser Mattführung, zuerst gezeigt als #5 im Manuskript 'Bonus Socius' vom Ende des 13. Jahrhunderts (P1129965 oder P1156023). Den Rekord hält die P1124546 von Günther Jahn 1983 mit 16 Zügen! Ansonsten sind mir nur Fassungen bis zu 10 Zügen bekannt.” [Klaus Funk] Eine “schöne Miniatur” [BL], “bei der sogar der wL noch geopfert werden kann!” [JB]

Henrik Juel: C+ Popeye 4.61 also
Asymmetry, but not very striking because of the proximity to the a-line
Still a very nice problem, which is solvable by hand (2021-02-07)
A.Buchanan: Nice to have an empty board for the nightriders to canter around in unblocked. That they are line pieces makes the uniqueness of the solution even more impressive. Someone must have already done tablebase for this endgame (2021-02-08)

A.Buchanan: Please forgive me but I think “under-promotion” is only meaningful for directmates and studies. That’s why I had put in promotion as a keyword, not under-promotion. In helpmates, promotions need to be distinguished of course, and we can put in the officer type in the parameter slot. Under-promotion would still need such a parameter because it’s inexact itself: the worst of all worlds. Even for directmates and studies of course some people consider knight promotion not to be an under-promotion at all, but I wouldn’t go that far myself. There are far too many keywords covering promotion, and at some time we should clean them up, but in the mean time I am open to considering another opinion if it is explained to me. Thank you.
