R: 1. Ke2xLf1 ~ 2. Kd3xLe2 ~ 3. Kc4xLd3 ~ 4. Kb5xLc4 ~ 5. Kb6-b5! ~ 6. Sa6xSb8, dann 1. Sc7#
S N Ravi Shankar: This problem is not mine. (2019-01-02)
Mario Richter: My first guess for the solution was:
R: 1. Ke2xLf1 2. Kd3xLe2 3. Kc4xLd3 4. Kb5xLc4 5. Ka6xLb5 Lc6-b5+ 6. Sd7xLb8, dann 1. Sb6#, but that doesn't work because of 5. ... Ld7-b5+!
Does someone see (or know) the correct solution? (2019-01-03)
Henrik Juel: No, because with 1... Lh3-f1+, 5.Ka6-b5 thr. 6.Sd7xLb8 fails similarly on 5... Ld7-h3 (2019-01-03)
S N Ravi Shankar: Does adding a black knight on e6 cure? 1. Ke2xLf1 2. Kd3xLe2 3. Kc4xLd3 4. Kb5xLc4 5. Ka6-b5! followed by 6. Sd7xLb8 and now 1. Sb6#. (2023-02-20)
S N Ravi Shankar: The problem appears to be sound. 1.Ke2xLf1 2.Kd3xLe2 3.Kc4xLd3 4.Kb5xLc4 5.Kb6-b5! followed by 6.Sa6xSb8 and now 1.Sc7#. (2024-02-18)
A.Buchanan: WinChloe also gives the same composer. A curious situation, but at least the problem attributed to you appears to be sound! (2024-02-19)
Adrian Storisteanu: Above the "diagrammes" diagram there is: R. SHANKAR, Inde. In the volume index, under RETROS: this is the only problem of a composer named (just) "SHANKAR" (one original), while "RAVI SHANKAR" is a different author (with two originals). (2024-02-20)
A.Buchanan: I suggest that S.N.Ravishankar check the reaponse to the query (A='Shankar' or a='Ravishankar') AND NOT A='Shankar Ram, Narajan' as there are many other similar retros which are attributed to Ravishankar. If he can state here which ones are not his, I will happily modify the data. (2024-02-21)

Henrik Juel: In parts a and b Ta1 has moved (because Kc2 just came from b1), so White may not castle
These parts are C+ Popeye 4.61
Part c is not clearly defined; if it is Bb3-a3, then it also is C+ Popeye 4.61 (2022-02-19)
A.Buchanan: I agree about part (c). I wonder though about (b) - it seems pointless. If there is also a part (d) which combines (b)&(c), then it does have a unique solution (with checking key) 1. De2+ Kb3 2. Sc5# (2022-02-20)

Across these two cases, both castling rights are demonstrated.
If we can assume that none of the White pieces in the first row has yet moved, then we must assign the move to Black. When this was published in The Problemist, opinions were divided. "White, to prove that the move is Black's, begin by claiming the right to castling on each side: and as they cannot in fact make both castles at once to establish this claim, it is sufficient to make one in each variation." "The solution consists of all the variations, and it is sufficient to have 0-0 in just one variation, since the small castling is enough to show that the move is Black's". "Since White claims the right to kingside castling, Black is forced to offer the opportunity" "No solution on 0. ... Rh1"
Si nous pouvons assumer qu'aucune des pièces blanches de la première rangée n'a encore joué, alors il faut attribuer le trait aux Noirs. D'où: 0. ... Rf3: 1,O-O+1 Re4 ou e3 2.Tae1# 0. ... Rhl: 1.Dd2I Rgl 2.O-O-O# Quand cela fut publié dans The Problemist, les avis furent partagés. "Les B., pour prouver que le trait est aux N., commencent par revendiquer le droit au roque de chaque côté: et comme ils ne peuvent de fait effectuer les deux roques à la fois pour établir cette revendication, il suffit d'en éxécuter un dans chaque variante". "La solution se compose de toutes les variantes, et il suffit d'avoir O-O dans juste une variante, puisque le petit roque suffit à montrer que le trait est aux Noirs''. "Comme les Blancs revendiquent le droit au petit roque, les Noirs sont forcés d'en offrir l'opportunité""Pas de solution sur 0. ... Rh1 :"

A.Buchanan: My feeling is this doesn’t work, sadly. In an adversarial stipulation, Black can simply avoid ever playing the line that allows White to “prove” that Black had the move. In a helpmate on the other hand I suppose if PRA-AP is expressed properly, there should be no problem playing multiple parts. (2022-02-15)

A.Buchanan: What's the idea? If it's a length record, can't we shift all the pieces up and put wK on a1 to increase the solution length by one. (2022-03-15)
SCHRECKE: Andrew, it's look like an "A" for "Annemarie". (2022-03-15)
Henrik Juel: This is not the best-looking A, I have seen, so it should not be Keyword'ed Letter problem
Incidentally, the problem can also be tested by Popeye, in a flash (2022-03-15)
A.Buchanan: Thanks all! Letter A must be the concept, although I must admit I didn't see it. It's certainly closer to A than any other letter (excepting the Cyrillic alphabet) to it would be churlish to refuse it the keyword. I hope that, in the unlikely event that Hans ever dedicated a letter problem to me, he would use a less wispy font :) (2022-03-16)

A.Buchanan: A small group of similar problems forces some short Round Trip across past and forward play. The last move is not uniquely defined (it may be a capture) and is not mentioned in the stipulation. However the genre includes retro. This means that an aesthetic criterion (e.g. existence of Round Trip) can define whether a composition is subject to 50 move rule or dead position rule! (2021-10-31)

Dazu wurde in BuB 2/2021, f 246, 07-09/2021, S. 191 geschrieben: "Dieser Rekord (C+) leidet an der illegalen Stellung mit Weiß am Zug."
t/Erhaltungen, t/Rex solus
Max Witte: Ich sehe keinen letzten schwarzen Zug. Versetzte man den Tf7 nach h7, sähe ich einen. (2021-07-08)
Max Witte: Aber dann ist 1.Lg7 kein kein Patt. (2021-07-08)
A.Buchanan: Maybe position legality is not considered a concern for this task (2021-07-08)
Mario Richter: Usually, there a separate record lists for legal positions and illegal ones.
So I think legality plays a role ... (2021-07-09)
HBae: Stellung mit wTh7 siehe P1103734 (2021-07-09)
HBae: Das dürfte inkorrekt sein, mit C- zu kennzeichnen. Der Rekord ist gleichzeitig materialbezogen vgl. P1103735 mit 7 Steinen. Rekord für illegale Stellung mit 4 Steinen siehe P1237827 (2021-07-09)
HBae: Allerdings ist die Stellung aus der PAS erspielbar nur dass Schwarz am Zuge ist. Vermutlich hat EB gesehen, dass Weiss nicht am Zuge sein kann. (2021-07-09)
HBae: Vgl. auch P1108944 P1182404 (2021-07-09)

As such it was a correction of a problem published up to June 1871, when the tourney
was announced. The tourney book does not identify the original problem, unfortunately.

Der Autor meint, es wird immer schwieriger, einen äußerlichen Effekt zu implizieren, je weniger Steine auf dem Brett sind. Effekte sind hier vorhanden: Schlüsselzug, der "ins Nichts stößt", und zwei Idealmatts. Dennoch: sommerlich leichte Kost.

The first 13.0 moves are correct by Euclide 1.0, but it takes some 4 minutes, so a complete test would probably take more than a day (2014-12-09)
paul: Jacobi checked the last 16 moves (in about 20 min). (2018-05-10)
Mario Richter: I would like to label this problem as a "Massacre PG", but the current definition of that term only knows of two-sided MPGs. Perhaps we could make the same differentiation as for "Homebase"?!
Btw., wasn't "popeye" best for such massacres?
rawbats confirms complete correctness of the problem after approx. 25 minutes. (2018-05-11)
Henrik Juel: Yes, Mario, Popeye is fairly good at this type
C+ by Popeye 4.61 in 57 minutes (2018-05-11)
A.Buchanan: @Mario: yes I agree it would be good to make massacre more specific. There are 69 massacres currently, almost all 2-sided, but maybe also some series-movers (unique or non-unique) which are currently not counted? (2018-05-12)
