Wieviel Bauern muß man entfernen, damit die Stellung legal ist?

Zero - the position is legal.
A.Buchanan: Isn't this a legal position? In each of the 4 pairs of adjacent files, one cross-capture suffices. So a total of 8 captures is necessary, with up to 14 available. (2022-03-17)
Henrik Juel: Yes, any master of the 20 bishops problem can see that the position is legal
The diagram must be wrong (2022-03-17)
A.Buchanan: Maybe it's a correct composition, with a humorous solution: "zero"? All that's wrong is that it shouldn't be tagged with keyword "illegal position". I will fix that (2022-03-17)

HBae: Originalaufgabe siehe P0502695, Quelle 'feenschach' kleingeschrieben!! (2021-05-24)
A.Buchanan: So this was Niemann's own correction, I guess. When was FEENSCHACH renamed feenschach? (2021-05-25)
A.Buchanan: Henrik: "Jungle & Garden" is a new perspective in the fairy chess terminology classification campaign. It comes from a frustration I've had in writing glossary entries (not just in chess, but in my professional life) as to what I am trying to achieve with a definition. Is it ever "good enough", or can it be? It basically says that any term is either a *description* of an aspect of the chaotic real world ("Jungle") or it's a *definition* in our provisional model of that world ("Garden"). Words like "love", "game", "fairy", "tempo", "joke" are all Jungle words. The meaning is derived from consensus: like a ship's anchor cable is made up of many fibres, in Wittgenstein's famous image. On the other hand, we are trying to build (in our software & databases) formal models which can classify, solve and compose chess problems (Gardens). The terminology in any one can and must be exact, as it emerges bottom-up from formal mathematics, logical and informational structures. However these terms are only provisional, and different Gardens may have different interpretations. It is acknowledged that they are not the same as similar terms in the Jungle. They are our best shot so far. It is valid to list (in a civil way) perceived shortcomings between the Garden and the Jungle, which can be put in a backlog to be handled later. "Legality" is an excellent example of a Garden concept, which is why I am exploring it currently. Comments welcome. (2021-05-25)
A.Buchanan: A database crosses the divide: it must store accurate "photographs of the jungle". Any transformation of these compositions (e.g. rationalization of the stipulation) cannot over-write primary jungle data. I thought this composition did that, but I think it's Niemann's own correction published later. (2021-05-25)
Henrik Juel: Thanks for the explanation, Andrew (2021-05-25)
HBae: Hello Andrew, renaming of FEENSCHACH to feenschach from January 1971:

play all play one stop play next play all
Cook: e.p. not justified as R: 0.e3xd4 possible
VL: Unjustified ep-capture because of –e3xd4. For correction it suffices e.g. to add bSe3.
This is possibly a unique 2-move helpmate with ep-key and 2 solutions of the type 1.2.1.1 (at least so currently in the PDB).
Publi?ation details. H551 in the Helpmate section of the July issue, with no preview. Here is the text of the solution published in the Nov.-77 issue: “…White may have just played P(e3)xd4. Very few solvers have spotted this. Full marks for claim of no solution with correct reasoning but, in fairness, one mark for composer's intention. White cannot have just played K(a5)a6 in reply to Pxb6+ as too many captures by Black are required.” (2023-12-01)
A.Buchanan: Yes Valery you are right this must be cooked. However, I'm not a fan of +bSe3 because it spoils one of the model mates. Separately, I mildly prefer bPf7 to bPe6. (2023-12-03)
VL: I do prefer bPf7, as well. I don't see any way to save at least one of the properties Kindergarten Problem and Model mate (2) after fixing (what for these keywords have been added just now?). Besides, Andrew, please, refine the specification ((full) number and publication month 07-08). (2023-12-03)
A.Buchanan: Ok have added the publication details. The keywords are useful to indicate the aim, even though the problem is cooked. I guess there is a way to keep the model mates but it’s very clunky and probably +bSe3 is better (2023-12-03)

There is some choice in the retro path, but in the shortest resolution, the sK round trip is uniquely defined: e8-c8(castling)-b8-c8(switchback)-d7-d8-e8. Note that wTa, still stuck in its cage, was captured on c2.
Mu-Tsun Tsai: Can't believe that this one didn't get the 1st prize. The design is really brilliant! (2011-04-17)
Henrik Juel: Thanks for your nice words, Mu-Tsun. In 1997 there were few retro problems in Thema Danicum, and they were judged together with fairy problems, so the competition was stiff. (2011-04-17)
Henrik Juel: Thanks for posting the solution, Andrew

sK could wander around on the queen side while wS pendulates on, say, g4 and h2; but in the shortest resolution the sK round trip is unique (2021-01-17)
A.Buchanan: welcome Henrik - also added the famous sLf8 to the animation (2021-01-18)
Henrik Juel: Six of the pawn captures happen to be uniquely determined, namely
b5xLc6xTd7, c3xDd4
d3xTc2, d7xLe6, g7xSf6 (2021-01-18)

(A. Beine). Für eine Ultraschachzwang-Aufgabe gibt es reichen Inhalt: wB-Minimal, insgesamt 7 D-Umwandlungen, wobei die beiden wD-Umwandlungen durch zwei verschiedene Schlagfälle realisiert werden. Dazu in a) doppeltes Kreuzschach und in b) doppelter Batterieabzug des sK.
Ganz unüblich schwierig. Vom Blatt spielen läßt sich das keineswegs (WW).

(Beine). Dargestellte Themen: Miniatur-Oneliner, neutrale AUW mit Umwandlungswechsel aller drei nBB, im 2. und 3. Zug reziprok vertauscht, Mustermatt. EB: da ich kein Löseprogramm für Ultraschachzwang habe, mußte ich wohl oder über selbst ran. Klar war eigentlich von vornherein, daß nur eine neutrale Batterie mit einer Front-Dame erfolgreich sein konnte. Den genauen Ablauf zu finden, war dann doch recht mühsam. Die b)-Lösung ist dann mehr oder weniger nur ein Anhängsel, um die AUW zu komplettieren.

Erster Züge der schwarzen Bauern: a7xSb6, c7-c6, d7xSe6, f7-f6, h7xTg6
Henrik Juel: The first moves by black pawns who moved were: a7xSb7,
c7-c6, d7xSe6, f7-f6, h7xTg6. Retroplay e.g. -1.Ka4! b6xLc5 -2.La3 c5xTd4 -3.Lc1 c6 -4.b2xDTSc3; bring wK to g1 and wT to f1, and unpromote the uncaptured black officer on e1, e.g. -11.Kh1 Y=e2 -12.Kg1 e3 -13.0-0 f4xDe3 -14.De2 f5
-15.Dd1 g6xLf5 -16.Ld3 h7xTg6 -17.Lf1 c7 -18.e2xLf3 etc. (2006-07-13)
Henrik Juel: A few additional remarks may be necessary
White captured [Lf8] on f8, a2xb3x...xf7, b2xc3, and e2xf3, so all missing black men except for [Lf8] were captured by white pawns
Black captured a7xb6xc5, cxd, d7xe6, and made three more captures
d7xe6 happened after e6xf7, before [Lc8] could exit, implying:
1. [Pa2] captured DTTSS
2. [Lc8] was captured on f3
3. [Ph7] captured hxgxfxe, promoted on e1, and the promotee Y was captured on c3
Early in the retroplay Black must uncapture [Lc1] quickly, so White can retract b2xYc3 before Black runs out of pawn retractions
Later, White must retract [Dd1,Ke1,Lf1,Th1] quickly, so he can retract e2xLf3 before Black runs out of pawn retractions (2017-09-11)
Henrik Juel: This problem was awarded a Commendation (Lob) by judge Klaus Wenda in the informal fairy tourney (including retros) for 2005 (2021-06-18)
A.Buchanan: A terrific problem, and quite recent! (2021-06-19)

Informalturnier 1986 Rest, Preisrichter Gerhard E. Schoen, Preisbericht f-94 S. 252
Eine unscheinbare Stellung mit erstklassisch tückischem Lösungsverlauf, der eine SLTTD-Umwandlung mit Idealmatt als Thema zeigt. Vergleicht man dieses Problem mit ähnlichen aus der Glanzzeit dieses Genres, den frühen siebziger Jahren, dann erkennt man erst diese Leichtigleit der ausgefeilten Darstellung, ohne dabei Komplexität und Lösungsschwierigkeit zu vermissen (G.E.Schoen).

A.Buchanan: While it's true that there is no legal last move for Black, does this make the problem a "Retro"? The reasoning is hyper-trivial. Was this intended as a joke? Or is there some context for the composition? If only I knew a Danish person who might have some knowledge of the culture at the time... :) (2021-10-07)
Henrik Juel: Ha-ha, here goes
Knud Hannemann was the best danish composer in his prime, but this is surely a joke
Possibly the try 1.g8=D#?? was intended
Skakbladet 1972 is not available for me, but it might throw some light on the problem (2021-10-07)

Henrik Juel: White has the move

James Malcom: Is the given retraction unique? (2020-11-08)
Henrik Juel: Unique up to 11.c2-c3, I think (2020-11-08)
Henrik Juel: One of my favorite retros with just kings and pawns
even though the retroplay is not completely unique (so my previous comment is imprecise)
R: 2... h3-h2 3.Lf6-h4 h4-h3 or 3... f5-f4 also work
but not R: 1.e3-e4? or 1.c5-c6?, and White runs out of pawn retractions
nor 2. e3-e4? or 2. c5-c6? f5-f4 3. Le5-g3, and same difficulty (2020-11-09)
Henrik Juel: In the forward play we have several temporal implications, e.g.,
e2-e3 before b7xLa6 before g2xLf3 before g3-g2 before h2xg3
d6xc7 before e7xd6 before b2xLa3 before f4xLg3
Thierry was inspired by P0008574 (2020-11-09)
James Malcom: I see the similarities as well. If Thierry's last 21 moves, stopping at 11. c2-c3 of course, are indeed unique, it seems to be the record for a kindergarten position? (2020-11-09)
A.Buchanan: I think the last 2 single moves are determined. Prior to that it could be f5-f4 or h3-h2, no? (2020-11-10)
Henrik Juel: You are right, Andrew
So, no record, James (2020-11-10)
James Malcom: Ah well then-the linked problem with 16 moves by Gerd oughtta be it then, from what I've searched so far. (2020-11-10)
A.Buchanan: Isn’t the retro record one of the Breyer versions by Thierry Le Gleuher? (2020-11-10)
James Malcom: As far as I know, the TOTAL retro record is, all from P1339006, by Theierry indeed: Type A, 100 moves, Type B, 101 with bP6-h6 & White to move, and, finally Type C, 102 with bP6-h6 and wSc7-a8. (2020-11-10)
James Malcom: For Type B, I meant "bPh5-h6." (2020-11-10)

Mario Richter: 2 Anmerkungen:
1. Danke an "Moldenhauer" für das oft sehr zeitaufwendige Testen!

2. im konkreten Fall scheinen mehr als 39 Stunden für einen 3-Steiner darauf hinzuweisen, daß es in 'popeye' noch Optimierungspotential (zumindest speziell für Aufgaben mit Märchenbedingung "Haaner Schach") gibt [mein eigenes Programm 'rawbats', das normalerweise mit 'popeye' nicht mithalten kann, schafft die Prüfung in 10 min 3 sec!] ...
Vielleicht kann der eine oder andere Problemfreund mit Zugriff auf die entsprechenden Programme mal mitteilen, wie lange WinChloe, Alybadix, jacobi etc. für die Prüfung brauchen?! (2022-09-17)

Teppo Mänttä: Cooked as stated in ST June 1995. imo should be removed from the PDB. (2021-04-24)
Mario Richter: The PDB documents published problems. This problem has been published - so why should it be deleted?

Furthermore, if it is cooked, why does it have the C+-Label? (Can some kind soul please computer-test it again?) (2021-04-25)
A.Buchanan: Hi Teppo, we all have cooked problems in PDB. I personally find it slightly embarrassing, but I try to see the bigger picture that PDB aims to be a comprehensive historical record. Where corrections or improvements followed quickly from the original, there's no point in keeping every version: that would just be distracting. But there's no shame in keeping these efforts.
It is odd that they were marked by Hans Gruber as C+. We should certainly re-test with today's technology. Can we come up with a better syntax for the stipulation? It seems that the (cooked?) solution above is =14.5 (2021-04-25)
Teppo Mänttä: It was supposed to be a length record with at least one dual-free variation. Cooked in this case means that there are not any dual-free variations. (2021-05-02)
