play all play one stop play next play all
1.exf3e.p. Bc2# is the only possible solution, but this necessitates R: 1.f2-f4. Can we prove this?

(13+13) with 1+2 pawn captures. Bf8 captured at home, so to satisfy White appetite, the missing Black pawn (a or b) must have promoted via c2 on c1. Two more White units must be captured to allow this.

The kings cage can only be unlocked by retracting WPc2. But the clock is ticking as there are only 6 black moves which can be retracted.

The promoted piece was captured on e3 or h3. If either capture is undone, then a White bishop square is cut off, so WB must be replaced prior to this.

Now the order of the early moves is: WdP moves, WQB & WQR escape, BP promotes on c1 to X (capturing WR at some point), X captured by WP.

So the first White capture must be dxNe3 and the second White capture releases gxXh3. The second White capture releases WKB & WKR. WKR captured by original BfP.

The clock starts ticking with gxh3. Black has 6 pawn moves. WKB has 3 moves to reach h7. WR has 3 if it goes via d file, or 2 if it starts on g1 (in which case WfP or WQB must also move once). So certainly at least 6 White moves. Last move was therefore White (even if the stipulation didn't tell us), and it can only have been WfP coming from f3 or f4. If it had been coming from f3 it would have blocked WKB in its progress, so the last White move was indeed R: 1.f2-f4.

WKR did therefore move from g1-g4-e4, and R: 1. ... fxRe5 2. Rg4-e4. Prior to that, move order not unique, but counting still exact.

Note that WN loitering on b4, pretending to be part of the cage, is present on the board just to make up the numbers.
Jeliss: "Obstruction of passage square f3 to Bishop of same colour."

"Version 'Pittsburgh Leader' 08.06.1913"
Yoav Ben-Zvi: Appears as the first problem (D445) in the booklet on Dawson's RA problems by G.P. Jellis. The obstruction that occurs in the Try -1.Pf3-f4?, by WP of WB, is described as "obstruction of passage square". It is not considered by Dawson and his disciples to be a Retro opposition. Dawson's conception of RO was quite broad, it included cases where the interference was not by occupation of the target square, so the only valid reason that I can see to exclude this case is that the 2 pieces involved are both of the same color. Fabel's definition explicitly excludes "Monochrome RO". I conclude that it would be preferrable to interpret RO as a bi-chromatic interference. The keyword Retro opposition should be removed. (2018-04-07)
A.Buchanan: To my mind, RO involves some kind of parity-tempo issue between the sides, not just some kind of race-tempo. If it was just about "bi-chromatic interference", one might say that bPe4 blocks wBh7 from an immediate retreat, so it has to be wPf4 that retreats first, legitimizing the ep key. So I agree this is not RO. (2024-01-06)

White's last move was certainly one of the two double pawn hops. The last move couldn't be d2-d4 because Black's pawns had already captured 10 of White's pieces, and playing d2-d4 would have resulted in wBc1 being White's 17th piece. So, the only solution is 1.gxf3 e.p.
Viktoras Paliulionis: The last move couldn't be d2-d4 because Black's pawns had already captured 10 of White's pieces, and playing d2-d4 would have resulted in wBc1 being White's 17th piece. So, the only solution is 1.gxf3 e.p. (2023-12-30)

A.Buchanan: Can shift bQd5 to c4, while replacing bRg5 with bP to reach Meredith status. bBh4 can also be downgraded to bP. But probably even more economy is possible by shifting pieces one file to the right, keeping the ep, White tempo & model mate, which seem to be the main features (2022-11-30)

C+ Popeye 4.61, except for the promotion dual (2020-08-03)
A.Buchanan: There's no keyword for an untolerated dual promotion! (2020-08-03)
Henrik Juel: Yes and no, Andrew
What about the cooked label? (2020-08-03)
A.Buchanan: Hi Henrik: this is obviously intentional. I tried to replace the pawn promotion with wDh8-h7+ but I ran out of pieces. I guess that Bebesi had the same difficulty. The word "cooked" seems too strong to me, but it's obviously a significant defect though (2020-08-04)
A.Buchanan: The bar is higher for helpmates than other problems, and this is unsound. However it’s not cooked but dualled. Yet all we have is “cooked” so I suppose it is in PDB-speak. I’ve added that and removed the 2.1… (2023-08-07)
Joost de Heer: Is there an 'unsound' keyword? (2023-08-07)
A.Buchanan: Hi Joost: no there isn't. It can be added, the challenge for any new common keyword would be populating it for more than a few values. (2023-08-07)
A.Buchanan: This time round, I've managed to find a fix. Bebesi's correction in WinChloe 66992 has non-standard wL. I have a feeling I've seen a similar one by Andrey Frolkin & someone else recently with a different matrix, and also non-standard wL. I've sent my effort to Joaquim Crusats at Problemas for his assessment (2023-08-08)

Yuri Bilokin: The fifth solution is not necessary, the author has kept it, so after adding the white pawn to the b4 square and without removing the black bishop, we fully preserve the author's intention.

Benkö in 'My Life': "Creating a double Queen sacrifice like this is quite an achievement, yet the judge in the Schach Echo helpmate contest didn't appreciate it and only awarded the problem an honorable mention. Later, this problem became one of the most popular examples of the bad judging that is so common in publications."
TLi: a) There are no sacrifices, only captures.
b) The wQ can be omitted without changing the solutions.

Bad judging, indeed! (2023-02-16)

Es war zum Abschlus noch ein ganz besonderer Gag - "zum wiederholten Male stellt der Autor die Löser mit einem Retro-trick auf die Probe".
"denn eine rückshauende Betrachung der Stellung ergibt daß Weiß nicht zuletzt gezogen haben kann, mithin also am Zuge ist."
"aber da gibt es wohl jede Menge Variationsmöglichkeiten bei den Läuferzugen.
In diesem speziellen Fall blieben sie unbewertet, zumal es ja auch eine spezielle Spielart, das sog. "Varianten Hilfsmatt" geben soll."
"Fazit: eine gute Mischung!"
"Durch die Hilsmatt-chwemme war es eine recht einfache, aber nicht uninteressante Angelenheir, vor allem die Nr. 13412 und natürlich der Retro-Witz haben mir gefallen."
Dennoch "Ein kleines Selbstmatt dazwischen (so in neun Zügen oder mehr) ware schon gang recht gewesen."

Some retro tries h#6 but not distinct.
Cook: The 6 helpmate variants seem to be intended.
A.Buchanan: If one wanted a unique solution, -wLc4 +wBd6 seems the only way (2023-04-24)

„2 x 3-fache konsekutive Rückkehr von sSc8 und damit laut PDB Erstdarstellung“ (Autoren). „Originelle Inszenierung zweier analoger Springerausflüge mit Rückkehr“ (KR). „Toll! Zweifache Rückkehr – habe ich so noch nicht gesehen“ (HR). „Da hat sich die Elite getroffen“ (WaM).
(MD1825)

Rolf schreibt dazu: Zweimal dreifache konsekutive Rückkehr von sSc8 (und damit, laut PDB, Erst-Darstellung), auf verschiedenen Wegen, mit Beseitigung weißer Masse (g3/h4) zwecks jeweils zweimal Linienöffnung für den weißen Turm, davon je einmal nach Hinterstellung weißer Turm/schwarzer Springer. Verschiedene Wege des weißen Turmes von h3 nach b7. Identisches Mustermatt. Identische weiße Züge eins bis drei; aber alle (!) fünf ZWEIfachen konsekutiven schwarzen Rückkehren in der PDB (alle mit jeweils VERSCHIEDENEN schwarzen Thema-Figuren) haben in allen (!) Lösungen sogar identisches weißes Spiel von Anfang bis Ende, also in allen SECHS Zügen! :-) - DOPPEL-Setzung der EINphasigen P1396043, vom November 2021.
