Yuri Bilokin: the idea is not new P1005163 (2022-08-06)
Jean Marc Loustau: ***
The matrix and the mates are indeed the same; but in this problem (P1100532) there is one more significant feature which is, in fact the main idea (which is not on the P1005163):
The 2 white thematic pieces can already play on the mate square in the diagram position: thus we have a kind of "peri-white Grimwhaw" (a 3 moves manoeuvre to reach the mate square which was already reachable).
Of course I did no know the P1005163 when I have composed this one... I would say "fortunately", because if I had knew it, probably I would not have worked on this matrix: my final result, in my opinion, is interesting enough with its new feature to deserve the publication. (2022-08-14)

With the typo wPd5 corrected to e5, the two forward candidate solutions are correct. How about the retro? Assume that White castling rights remain. bBg5 is promoted, and did so on c1 or g1. In either case, there were 6 pawn caps by Black, but in the former case, the blockaded wRh was not consumable. So the promotion must have been on g8, and White can't retract h2-h3. The missing White unit is light B, so was not just captured on e5 or b4. wRf6 is promoted, say wPd, which would have involved no captures.

This leaves b2-b4, preceded by Kb4-c4+ and before that Sd6-b7. Prior to b2-b4, why couldn't bQ have just played e.g. Qa8-a5+ instead? Because there would still be no prior move: wSb7 can't have just come from h5 or e6. Similarly Rc3-a3 has no precedent.

We don't know exactly what happened to sLc, but that doesn’t affect the soundness. It might have enabled wPc or wPd to capture. wPd did promote, but maybe it was wPc that after capturing promoted to T. Alternatively, Sd6xLc7 was possible.

Henrik Juel: Andrew, can you throw any light on this problem? (2022-05-28)
Henrik Juel: Gerald, in AP problems like this one White must castle to legitimize the ep capture key (2022-05-28)
A.Buchanan: Hi Henrik, Gerald. I found this one in WinChloe with the current diagram. It gave the "solution" 1. axb3ep+ Sxa5+ 2. Kd5?? 0-0-0#. However when I tried running the WinChloe solver just now, it said there's no solution. Quite right: Rf5 controls d5. I don't think we can shift Qa5 to e5 though.
My first thought is that wPd5 should be on e5. Check my suggested solution in the solution text. However, as you will see, I think we need a second thought as well! Hope the finest retro minds can figure this out. Failing that, we could ask Igor. (2022-05-28)
Mario Richter: The diagram in the reprint in 'Uralsky Problemist' is exactly as given here. The solution given there without further explanation is: 1. ab+ (e.p.) Sxa5+ 2. Kd5 0-0-0#!
Notice that the second black move doesn't contain a capture sign!

Some typos in Andrew's analysis:
The black potential promotion squares should be c1 and g1.
White's last move couldn't have been b3-b4?? simply because that would give an illegal check. (2022-05-28)
A.Buchanan: Thanks Mario for the careful reading. I’ve fixed the errors. Pd5 may be a typo in the reprint then. It also creates a bogus retraction d4-d5, so I don’t think it can be right. Now for Igor. (2022-05-29)
A.Buchanan: Joaquim Crusats spotted R: 1. b2-b4 Kb4-c4+ 2. Sd6-b7, which I'm sure is the intended retraction. So we diagnose a single typo that occurred in the Uralsky reprint diagram: wPe5 appeared on d5. I suggest correcting it here. (2022-05-30)
A.Buchanan: Author confirmed this was a typo (2022-11-23)

18851 (Jean Lochet). I) 1.S:d7 Dc8 2.Se5 „(entfesselt d5, fesselt f5, verstellt b8, e7 und f6 – was kann man von einem Zug mehr verlangen?)“ (JS) Td4# (MM), II) 1.S:d3 T:f5 2.Se5 De4#. Diese Aufgabe konnte die Löser nicht erwärmen. Die Umsetzung der Idee „gelang nur mit dem behelfsmäßigem Wegschlagen des sTf5“ (VZ), dazu gab es „nur ein Mustermatt. Viel Materialaufwand und schwache Materialausnutzung. Hm“ (KHS), „viel Holz für wenig“ (BK). „Der auszuschaltende Tf5 wird je einmal eliminiert oder – eleganter – gefesselt; nicht ganz gelungen erscheint mir, dass der zunächst die Matt- bzw. Fesselungslinie der weißen Dame freiräumende Sc5 mit seinem nachfolgenden Selbstverstellungszug in Lösung I) nur die Deckungslinien von Turm und Läufer verstellt, die Verstellung der Dame dagegen ohne Belang ist“ (HJä). „Beseitigung weißer Bauern mit unterschiedlichen Linienöffnungs- und Verstell-Effekten. Es gab aber doch einige Unterschiede in der Lösungsstrategie und 1.– T:f5 wirkt auch sehr grob, um den weißen Turm in der zweiten Lösung mitspielen zu lassen“ (FRd). „Zwar gibt es einen Funktionswechsel Dame/Turm und Linienräumungen in beiden Phasen, aber der Rest ist entweder dissonant (Fesselung vs. Schlag) oder monoton (Verstellung auf demselben Feld)“ (MRit).

Gut“ (HJä). „Weiß erwandelt mit tatkräftiger schwarzer Hilfe jeweils eine Dame, die dann mattsetzt, nachdem die schwarze Dame blockt“ (JB), deshalb müssen „die Wege des kleinen Bauern zu den großen Damenfinals genau getimt sein“ (VZ). „Echo-Mustermatt, Exzelsiormarsch, Funktionswechsel zwischen sSh1 und sBd6, Umwandlung in weiße Damen, gute Materialnutzung. Die Aufgaben von RF gefallen mir immer wieder“ (KHS). „Es verwundert nicht, dass es zu diesen Exzelsiormärschen mit Spiegelecho Vorläufer gibt.

"wTb2/wTd4 können auf b8/d8 nicht selbst mattsetzen; erst ihr Ersetzen durch den jeweils anderen wT auf ihren Diagramm-Feldern ermöglicht diese Matts. Grund für diese Paradoxie: Das Opfer von sTb5/sTd5 ist der einzige Weg, diese Matt-Verhinderer auszuschalten." [Autor]
