Henrik Juel: Black makes 15 captures.
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)

Mit dieser Aufgabe hat BoL vermutlich erstmals den Begriff der ZeroPosition eingeführt. Hier zeigt die Verwendung der ZeroPosition auch thematische Geschlossenheit insofern, als bei Versetzung des wS auch UW in S erfolgt, bei wT auch UW in T etc. Es besteht also ein Zusammenhang versetzte Figur zu Umwandlung (eb).

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 :"

No. 8889 HN
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)

Cook: 1. Sf7!

BsS4 IM

Im Nachdruck im 'Geill. Courant' ist in die Forderung die Bedingung eingeschlossen: "De witte koning mag niet gespeeld worden" (der wK zieht nicht).
Wird damit evtl. der reklamierte Cook 1.Sf7 vermieden?

Im Nachdruck von Alexandre mit der Bedingung "sur la meme case" (auf dem gleichen Feld).
In Oscar Korschelt "Der gereinigte Alexander" jedoch berichtigt: "Ohne Bedingung".

5-fach Schlag derselben Figur im Rex-Solus-Wenigsteiner
(Autor).
Toll! (Hans Gruber).
Amüsantes Abseilen des schwarzen Läufers, bevor der weiße
König im Tunnel unter dem schwarzen Turm entkommt (MS).
Sehr lustig, der weiße König bewegt sich wie eine Nähnadel
auf der h-Linie (BG).
Nette Idee (TS).
Offenbar kein Rekord, aber schön (HB).
Im Fahrstuhl abwärts, feine Idee (Klaus Funk).
Wow, er holt den Läufer von seinem "`Hohen Ross"' (NG).

Last move?

play all

BTM the game is stalemate, WTM the game is dead.
If Black moved last it was R: 0. Kh4-h3 g2-g3+ retropat. So White moved last.
All missing pieces were captured by wP, and none can be undone immediately, even wPb3 & wPh7. However there is a try R: 0. Be8(f7)-h5? Kh4-h3 1. g2-g3+ Kh5-h4 2. B~-e8+. But then 0. ... Kh4-h3 was mandatory into DP, as White can't relieve the looming stalemate. The only solution is R: 0. ... 0-0 1. Kg2-h3, with many alternatives: basically anything but Kf1, Rg1 or Ne3, as Black must be allowed to respond Kg2. There is unique shortest “ghost play” h#1.5 living alternative to castling.

Objective: Type A Last move with uncastling
Henrik Juel: I see that retracting a2xb3 or g6xPh7 is no good
But R: 0.Le8-h5 Kh4-h3 1.g2-g3+ Kh5-h4 2.Sf7-e5+ Kh4-h5 3.e5xDf6 seems OK
Where is 'the looming stalemate'? (2022-04-09)
A.Buchanan: Retracting 1. Le8-h5 Kh4-h3 puts us in a position where Black’s move is mandatory and whatever White then plays, the position is stalemated (2022-04-10)
A.Buchanan: So in this line, the initial dead position was two single moves ago. One single move from dead position would suffice to show that Le8-h5 is not possible. (2022-04-10)

Cook: Leicht in 4 Zügen zu lösen: 1. Sb6 Ke8 2. Sg6 Kd8 3. Tf7 Ke8 4. Tf8#
Die Forderung ist daher zu ändern in: Matt in genau 6 Zügen.

Felber, Volker: Im Handbuch von Lange steht: 'Ohne die, von den alten Autoren auch wirklich versäumte, Bestimmung des Mattfeldes würde das Ziel schon in vier Zügen (...), welche zugleich eine andere Art der Schlussstellung illustriren, erreicht werden können. Bei Guarinus erscheint übrigens die Aufstellung so gedreht, dass sich der schwarze König auf h5, der weisse Thurm aug g8 etc. präsentirt.'.

Die Forderung beim Diagramm im Handbuch lautet: 'Matt auf c8 in sechs Zügen.'. (2020-04-21)
SCHRECKE: Nach 1.Se7 Ke8 2.Seg6 Kd8 3.Se6+ Ke8! geht zwar 4.Te7#, aber die Forderung 'Matt auf c8 in sechs Zügen' ist nicht zu erreichen. Damit ist das im Sinne der Aufgabenstellung UNLÖSBAR! (2020-04-22)

Arnold Beine: Die angegebene "Korrektur" von milan funktioniert nicht. Wenn der sK im 4. Zug nach d8 und im 5. Zug nach e8 zieht, kann Weiß die Forderung mit Matt auf c8 nicht erfüllen. (2024-02-18)

Jedes Fluchtfeld 4-mal gedeckt durch alle 16 weißen Steine

Stelle den schwarzen König in der Brettmitte und 16 weiße Steine so auf, daß jedes Fluchtfeld genau 4-mal gedeckt ist. Jeder Stein muß wenigstens ein Fluchtfeld decken, und der sK darf nicht im Schach stehen. Es sind keine Umwandlungsfiguren erlaubt.
Die Stellung ist legal unter der Annahme, dass Schwarz am Zug ist.
In dem fs-Artikel "Exakte Vielfachdeckung schwarzer Königsfluchtfelder" (fs-59 S.386ff) gibt C.Vaughan ausführliche Erläuterungen.

Original-Quelle lt. Autor: "Fairy Chess Problems, 11/1979"
A.Buchanan: Our Codex, says in Article 6 Special Types:
Additionally, and independent from the classification according to Article 5 [the regular genres: studies, directmates, helpmates & selfmates] there are a number of special types, including:
(a) Retroanalytical chess compositions
(b) Mathematical chess compositions
(c) Constructional chess compositions
But we don't have constructional chess problems as a class. Instead these are miserably and arbitrarily scattered across fairies, retro, mathematics and blank. Effectively the genre gives 0 information, and as a result they are hard to find. There aren't many constructional problems, but why not put them in the box that Nature & the Codex Committee designed for them. Yes they need to be legal, but as we well know, "legality does not a retro make". What do you think? Shall we ask Gerd to create a new genre for these? (2023-08-15)
James Malcom: That feels apt, yes. (2023-08-16)
A.Buchanan: Thanks James - you may have seen the Discord discussion on this in the *new* construction-tasks thread. Of course in PDB there have been a couple of keywords (construction tasks/records) used inconsistently. But that doesn't mean there shouldn't be a genre.
Also, suggest that the stipulation should not give the game away. A #2 with knight-wheel would not blurt "knight-wheel" in the stipulation. Here another bad effect of the lack of genre is that the thematic content is given as the stipulation. I don't know whether the stip here is actually then one used in the article, but we can keep it as "originalforderung". However for solving I suggest the stip should be the neutral "What is curious about this position?" This is in keeping with normal practice of providing the diagram & asking the solver to figure out the theme. (2023-08-17)

as part of the Chess Player's Chronicle, 1885 tourney (probably unfinished),
where the position appeared under the motto "Bresgar II"

A curious detail is that another competitor in the same tournament used
the motto "Equist" (at least that is how C. P. C. printed it), which is
remarkably close to Öhquist, another of the composers associated with the same position (P1173816).
But at the same time, that would be worthless for hiding the identity of the composer ... (2022-11-09)

Henrik Juel: Missing Joke keyword, I guess (2020-05-11)
A.Buchanan: Curious that retro a7-a8=sT discomforts the animation still - maybe you should report to Gerd? (I trouble him with enough stuff already - don't want to be the only one emailing him! :-) (2020-05-11)
A.Buchanan: Maybe +sBe7f7 to refute R. ... e8=sK/fxe8=sK :-) Note this "cook" is actually prevented in the original. (2020-05-11)
A.Buchanan: Oops and a more major cook R: 1. Se8/g8-f6+ (2020-05-11)
James Malcom: This problem was only half-finished before I fell asleep. It’s fixed now. (2020-05-11)
A.Buchanan: Great! You could save another piece I think -sLg6, -sBf7, + sDf7. This also removes the obtrusive promotion (2020-05-11)
James Malcom: Yes, that is true. Position edited. (2020-05-11)
James Malcom: I see nothing wrong with fiddling if it improves economy. (2020-05-11)
A.Buchanan: If promotion to Bl unit is allowed, can’t Bl just have played e8xd7+ or g8xh7+? Can replace bPd7 with bR but eliminating bPh7 is more complicated. Need +wPh7 +bPg6h6. And also bRb7 to prevent discovered check by bPc8 prior to e7-e8=bK. I think that’s watertight now! :-) (2020-10-13)
A.Buchanan: The issue is that there are two or three levels of Bl promotion joke: this problem relies on the "basic" joke where black officers can be created. But where's the line to stop us promoting to Bl pawn or king? If we go that far, then a position like this 2kr3K/1r1r1qrR/7p/8/8/8/8/8 is required. Oh dear: sorry to have brought it up :( (2020-10-13)

Within hours, the English problemist Michael McDowell sent me a Belén problem that was both a Meredith and a three-mover.

(diagram)

"Or start Na4 on c3 for a 9-piece setting if you don't mind a flight-taking key," he added. Man for man, that setting was later independently also sent to me by Joshua Green. (The key is then 1.Na4)." [P1380105]

A.Buchanan: The castling & e.p. conventions are not inherently retro, although they may combine with other content. We don't enough about the history of the game, so the convention simply decides (2020-09-21)
James Malcom: Wrong problem to comment on, Andrew? (2020-09-21)
A.Buchanan: Hi James - I should have said: this problem was marked Retro not #3, so I changed the genre. My earlier comment is an explanation (2020-09-22)
