A.Buchanan: I don't see how to correct this pleasant problem, while retaining miniature status, the retro logic + the model mates. With an extra Black pawn, I found 8/2p5/2N3K1/8/4BkN1/3R4/5P2/8. With just 7 units, I seemed to need non-standard material, e.g. 8/5B2/5K2/8/4BkN1/3R4/5P2/8. If anyone manages to salvage this one successfully, pls let me know. (2021-10-08)

Hans-Jürgen Manthey: ein wBc5 repariert die Aufgabe

Nightrider: Obwohl die Unlösbarkeit bereits bei der Lösungsbesprechung vermerkt wurde, hat Ahues die Aufgabe offenbar nicht korrigiert. Es ist unwahrscheinlich, daß ihm die Möglichkeit +wBc5 entgangen sein sollte (aber wahrscheinlich hat er sich dabei an der doppelten Deckung von d6 und an dem Wegfall einer Nutzung der Turm(ent-)fesselung auf der c-Linie gestört?). - Eine Möglichkeit, die möglichst viel aus der Originalversion beibehielte, bestünde aus der Vertauschung von Verführung und Lösung vermöge Ersetzung des sSh3 durch sBh3. Dann hätte man: 1...d3+ 2.Dg4#, 1.Db8? d3+ 2.Sd4#, 1...d5! (pikfeine Widerlegung, die Entfesselung des sTc4 nutzend!, eben nicht 1...d6? 2.Dc8#), 1.Da8! d3+/d6 2.De4/Dc8#. (2021-11-27)

Originallösung (1880, S. 213):
Dalla posizione apparisce che il Nero deve avere lamossa, perchè nessuno de'suoi pezzi può avere avuto l'ultimo tratto.
Cioè:
a) Il R nero non può coll'ultimo tratto esser venuto da 5 A pr; allora l'ultimo tratto del Bianco dev'essere stato C 6 D, ciò che fa supporre , o che il tratto penultimo del Nero sia stato A 2 A sc. (ma di dove è venuto in tal caso l' A?), o vhe il C ha preso un pezzo nero a 6 D; ma i Pedoni 4 R, 4 A, 4 C hanno preso tutti i pezzi neri che si trovano nel diagramma.
b) Il P 7 TD che è venuto da 6 C es ha preso tutti e due i pezzi bianchi mancanti non può essersi mosso nell'ultimo tratto.
c) Il P 3 R che è venuto das 2 R (perchè non pu`aver preso nessun pezzo) non ha fatto l' ultimo tratto; il che si può vedere dalla posiziopne di A 2 A (che non può essere il P A R trasfigurato).
d) La posizione del R bianco mostra che il C 5 T non s' è mosso ultamente.
Dunque da tuttociò apparisce che il B ha fatto l'ultimo tratto, e ora il Nero giuoca: 1. P 8 T fa D sc. 2. T 4 D C 6 A sc.m."
[Sinngemäß: Aus der Stellung geht hervor, dass Schwarz am Zug sein muss, da keine seiner Figuren den letzten Zug ausgeführt haben kann.
Nämlich:
a) Der schwarze K kann mit dem letzten Zug nicht von b5 gekommen sein, denn dann müßte der letzte weiße Zug Sd6 gewesen sein, was bedeutet, daß der vorletzte schwarze Zug Lc7+ gewesen sein muss (aber woher kam in diesem Fall der sL?); oder wenn der wS auf d6 einen schwarzen Stein schlug; aber die Bauern e4,f4 und g4 haben alle im Diagramm fehlenden schwarzen Figuren geschlagen.
b) Der sBa2, der von b3 und zuvor von der c-Linie kam und dabei die beiden fehlenden weißen Steine ??nahm, kann im letzten Leg nicht gezogen haben.
c) sBe6 kam von e7 (weil er keine Figur hätte nehmen können), kann aber zuletz nicht gezogen haben, was aus der Position des sLc7 ersichtlich ist (der kein aus dem sBf7 entstandener UW-L sein kann [letzterer konnte nicht schlagen und deshalb kein schwarzes UW-Feld erreichen]).
d) Die Position des weißen K zeigt, dass sich der sSa5 nicht zuletzt bewegt hat.
Aus all dem folgt also, dass W zuletzt zog, und jetzt spielt Schwarz: 1. ... a1=D+ 2. Td4 Sc6#

(Daß Autor, Löser und PR übersehen haben, daß der fehlende sLc8 nicht als Schlagobjekt für die wBB zur Verfügung stand, ist umso erstaunlicher, als ja andererseits eine analoge Analyse R: sBe7-e6 als letzetn Zug ausschloß.)
Cook: Illegal position in retro = unsound = "cooked, in crude PDB terminology"
Originalforderung: "Chi comincia a giuocare dà scaccomatto in 2 mosse. Dalla posizione dei pezzi come pùo scuoprirsi chi debba avore necessariamente il tratto?"

The problem is cooked in the diagram position with 1.Txg6!. Adding a bl. Knight a6 (+sSa6) is not a valid fix, since it would destroy the set play 1.--- 0-0-0. Therefore I suggest the correction +sBh7 (add a black Pawn h7). (2021-05-25)

1) Weiss zieht und setzt in 2 Zügen matt
2) Schwarz zieht und setzt in 2 Zügen matt

Lösungsbesprechung 10/1913, Seite 159: '1. g5-g6 mit Weiß am Zuge und 1. Dd6 mit Schwarz am Zuge. Das # soll durch den Anzug des w. K. gegeben werden. D i e s e L ö s u n g s c h e i t e r t a b e r an 2. f6-f7! Offenbar kann das # nur erfolgen, wenn Weiß schon g5-g6 gezogen hat, indem der schw. K. den Bauer f6 schlägt. Dieser Autosuggestion, daß auch mit Schwarz am Zuge, schon g5-g6 geschehen wäre, sind fast alle Löser zum Opfer gefallen, ebenso der Problem-Redakteur. Der Fehler wird wohl am besten behoben durch Versetzen des Lg8 nach f7.'
Hans-Jürgen Manthey: das weiße Matt scheitert Nicht(!) an f6-f7(?) sondern banal an Sf2xg4 !
versetze Sf2 nach e1 und alles ist Schick... (2021-10-24)

If Black preserves castling rights, there is insoluble retro-opposition between sSg8 (unpinned by wS uncaptured at c5) and wTTK, none of whom can triangulate in this position. Apparently "the stars are right" for the sSf7 to allow wKg6 to shift, but the sS route must pass through c6, and retracting c7-c6 means "the stars are wrong". Black must spend his last spare tempo a7-a6 to rectify the situation, and that means there is no possible move while waiting for wLh5-g6 to be retracted.
Cook: There is an easily fixed error in this version: wTa1 can't retract home at all if Black castling rights are retained, rendering irrelevant the subtle timing considerations.
Korrektur zu P1390750
A.Buchanan: Under opposition idea, if Black had an extra tempo (e.g. sBa6 on a5 instead) it would be ok for Black to castle. But that still wouldn't work. We need to unlock the cage with e2xf3, following the retraction wLf1. However wRa1 is locked out! Am I right? Can this be fixed e.g. by starting wBa2 on a4 instead? (2021-06-15)
Mario Richter: So the correction still is not perfect, because the need to bring wRa1 back home already makes black 0-0-0 illegal. But with your suggested modification everything seems to be ok. (2021-06-15)
A.Buchanan: Thank you, Mario. I considered today some new possibilities for Black queenside, but the fundamental challenge always seems to be: prevent Black retracting c7-c6 *before* the retro-opposition phase is entered. So the version I propose is more modest: r3k1nR/1p4pR/p1p1p1KB/2p3PB/6Pb/5Ppb/2P2pP1/7N. It does at least save three pawns, but does it work? (2021-06-16)
Mario Richter: I think r3k1nR/1p4pR/p1p1p1KB/2p3PB/6Pb/5Ppb/2P2pP1/7N doesn't work, because the saved pawns can be used to provide an extra tempo for White: before the black Knight shields on f7, he can uncapture a White pawn eg. on b6 ... (2021-06-16)
A.Buchanan: Oops haha and I was doing so well on this one - thanks. And there is no restriction on sS moving around, because the wT can vibrate indefinitely. Well in that case the earlier suggestion of wBa2 on a4 instead is the simple correction. (2021-06-16)

Henrik Juel: Yes, Mario (2022-09-12)
A.Buchanan: Could it be that bRb6 is meant to be on a6? (2022-09-13)
A.Buchanan: The point being that with bRa6, 1. d8=sL? La5! (not Lc7/Lb6 2. Sd7#/Te6#) So bishop promotion becomes a thematic try. (2022-09-13)
Mario Richter: I have access to the original issue of 'Shakhmatna Misl', so I can confirm that the black rooks are on a7 and b6. I checked some of the following issues to see, if there was a mentioning a of the cook and/or a correction, but without success.
Changing the cook 1. d8=sL! into a try would be nice, but I think the purpose of black Tb6 is to prevent the defense 1. ... Db3!, so unless I'm missing something, Andrew's suggestion doesn't work. (2022-09-13)
A.Buchanan: Thanks Mario - I didn't check enough. If further one swaps bQb8 with bRa7, and pushes wK to h2 further out of harms way, then I think the =S solution & =L try are sound: 1r6/q2Pp1P1/r4k1N/2N3R1/5p1P/8/4R2K/8 (2022-09-13)
James Malcom: Nice find, Mario; sweet fix, Andrew. (2022-09-14)
A.Buchanan: Thanks James. r7/q2Pp1P1/r4k1N/2N3R1/7P/8/8/4RK2 further saves a pawn and has better positions for the remote units. I suggest attribution is MM correction HJ,MR,AB. (2022-09-15)
A.Buchanan: Alternatively r7/q2Pp1P1/r4k1N/2N3R1/5p1K/8/8/4R3 economizes a wP rather than a bP. I don't know which version my esteemed co-creators would prefer to record this momentous achievement for posterity. I don't see a way to reach Meredith (2022-09-17)
