Adrian Storisteanu: Is the star "*" in the stipulation supposed to indicate a kind of "set play" in the retro part -- in effect a "-1s dann h=1"? Because there is one:
- 1.Ke2xQf3 & 1.Ke2-e1 Qf3-d3=. (2015-08-02)
A.Buchanan: That's a clever interpretation Adrian, I am sure you are right, and it's sound according to Deadpos (2024-01-13)
Adrian Storisteanu: A more precise stipulation would be something like: (-w -s)*, dann h=1 (2024-01-14)
A.Buchanan: Good idea. The convention is that * promises at least one set play instance. (2024-01-15)

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)

Mit folgender witziger Begründung des Autors: "If on the board are only KL-KL (and LL on squares of the same colour), by the rules of chess an immediate draw occurs! Therefore, the retro move Ka3-a4 is illegal." Ein Fehllöser: "Reichlich trivial." Ein Ratloser: "... oder wie darf ich das sehen?" TK hatte den Durchblick: "Die doppelte Rücknahmemöglichkeit kann man aber gar nicht übersehen (und schon gar nicht der Autor). Einzige Möglichkeit: nur Ka3xBa4, weil andernfalls die Stellung schon vorher patt wäre. Aber, aber: das ist remis, kein Patt!!" FR: "Meine 'Ehrenlösung' für diese Gruppe (hoffentlich stimmt sie auch)." WM: "Nette Pointe. Das erzähl' ich meinen Kindern, daß ich einen PLAKSIN gelöst habe." 1,2/I
A harbinger of Dead Reckoning-style reasoning, before that rule ever existed. As sound today in 2018, as when it was composed under "insufficient material for mate" rule.
Henrik Juel: Nice to see that I am not the only freak who mixes english text with german notation (to avoid the ambiguous B)
Were you inspired by this problem in your work on Dead Reckoning, Andrew? (2020-05-04)
A.Buchanan: Ha no: when I stumbled across DP rule I knew even less about chess problems than I know now, if you can imagine, and had never encountered this one which Werner Keym unearthed and published it in "Out Of the Box". Ecclesiastes 1:9 says "There is nothing new under the sun." Mario made this point about origin of Schnoebelen promotions too. Gollon's intepretation of Chaturanga (the earliest known forebear of chess) offers fascinating possibilities for Schnoebelen promotion, which I am sure the Indian retrograde analysts of 7th Century CE were adept at exploiting, in tablets alas now lost. See https://www.chessvariants.com/historic.dir/chaturanga.html.

The "insufficient material" composition does perhaps explain Plaksin's openness to the concept of DP, at a time when perhaps some noses elsewhere were being turned up, as he later composed with Kornilov *27* other DP problems, all to be found in PDB. (2020-05-04)
Ladislav Packa: Interesting, but on YouTube I saw a game (one of the actors was Magnus Carlsson), which ended in a position with only two kings and one of the players still made a move. (2020-05-05)
A.Buchanan: http://wismuth.com/chess/illegal-moves.html contains many other games where GMs were unable to tear themselves away from playing the dead game. I think it's kind of sweet that the GMs just can't stop playing. Have you got a link to the Carlsen game please, Ladislav? (2020-05-06)
Ladislav Packa: I'm sorry, Andrew, but I don't remember. I've seen hundreds of games on youtube. But I encountered similar cases in my own practice, mostly a joke, and the game immediately ended with a smile and a handshake. (2020-05-06)

The Chess Amateur 07/1926
P0008784

Längste BP ohne Schach. Welches war der letzte Zug?
R: 5899. Kg2xTh1
play all play one stop play next play all
The game ends after 50 consecutive moves without captures or pawn moves (loss of castling right is not included here), or when there is not enough material to mate (say K-K or K-KS). There are 30 captures and 96 pawn moves (including 8 pawn captures) available, so the longest game seems to last (30+96-8)x50=5900 moves. This cannot be achieved because of the move-loss when the draw-preventing move shifts between white and black. Niels Høeg believed that 2 moves were lost and stated the solution as 5898.- Kb7xTa8. Karl Fabel later showed that only 1.5 moves need be lost.

Since 1926, there have been some relevant innovations to rules and conventions
(1) 50 move rule applies only to retro compositions, and will trigger automatically (no issue with writing down the move). (Codex 1953?)
(2) Removal of rules about draw by insufficient material (Laws 1997)
(3) Dead position rule introduced (Laws 1997)
(4) 75 move rule introduced (Laws 2014)
(5) Dead position rule applies only to retro compositions (Codex 2015)
(6) Articles 9.2 & 9.3 apply to chess problems - this includes 50 move rule and excludes 75 move rule (Codex 2019)

This is certainly a composition rather than a question about over the board chess. And it is certainly a retro composition. So the 50 move rule will dominate the 75 rule. The standard interpretation of interaction between 50 move rule and Dead Position in compositions is that Dead Position assessment *is* aware of looming automatic draw by 50 moves. (Note there is a similar assessment for interaction between Dead Position and Draw by Repetition.)

So we can argue that the game cannot last to 5898.5 moves, because the final move leads to a mandatory draw: either the king captures the last officer, or the king avoids the capture and the game ends in draw under the 50 move rule. So the position is dead at 5898.0. But even 5898.0 is too long for the diagram position with the kings so far apart. In the alternate reality if the last capture of a rook does not take place, there must be sufficient moves left for the kings to come together so that the rook can deliver checkmate. This will take at least 6.0 moves.

There is also still an ambiguity in the rules as to whether checkmate overrides draw by 50 moves. This is explicitly mentioned in the 75 move rule, but not in 50 move rule. I assume that checkmate *does* take priority.

Or does a valid problem only exist in the context of the rules and conventions that pertained at the time of its composition? The Codex does not opine on this general point.

A.Buchanan: There's a question whether DP rule has visibility of 3Rep & 50M state. The current consensus among most of the tiny group who might care is that for retros, it does have visibility, but for purely forward problems, it does not. This align with the idea that by default 50M & DP rules apply only to retros (2023-09-06)
A.Buchanan: The old intended interpretation is protected under the Golden Age principle. Suppose we do apply modern rules, codex & clarifications. If Black just played Kb7xRa8, then the alternative leading to mate takes 7.0 moves, so this must have been Black's 5892nd move at the latest. If White just moved, then it was White's 5892nd at latest. So to maximize the length of the game, Black moved last. (2023-09-06) edit (2023-09-06)

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.

VL: One solution consists of two partial ones, and there is another, castling independent, solution. A rare scenario; cf. P1091926. Presently, due to Art.16 (3) of the Codex, the mark "RV" may be deleted from the stipulation. (2017-11-25)
A.Buchanan: Methodologically, I think that one applies PRA first. So there are two parts, and each has two solutions. One solution is shared across both parts (2023-08-22)

(W. ,A. Bruder). MW: Da das Aktivieren des abseits stehenden wS mittels 1.Sf6? zum Patt führt, kommt es "bescheiden" am Rand: 1.Sh6! Ke4 2.S:g4 Kd5 3.Lc7 Ke4 4.g3! Kd5 5.Sf6+ Kc5 6.Sd7+ Kd5 7.Lf4! Ke4 8.Sf6# IM. LV: For this problem I worked overtime! Der bekannte Mechanismus der Beschäftigungslenkung, aber der Schlüsselzug ist nicht leicht zu sehen (KHS). Eine hübsche mit Idealmatt endende Miniatur (AB)! WAB legte mir einen Vorschlag zur Verbesserung vor: wSg8 nach d5 versetzen (CO+). Lösung: 1. Se5! usw. Vorteil: kein abseits stehender wS. Allerdings hat sich keiner der Löser über die Platzierung des wSg8 negativ geäußert. Im Gegenteil: ein Zug des wS wurde eher als möglicher 2. oder 3. Zug ins Auge gefaßt. Ich meine aber, daß die neue Version einen harmonischeren, oder besser: ästhetischeren Eindruck hinterläßt. Gesamteindruck von KHS: Durchwachsenes Angebot: es kann eben nicht jeden Tag Sonntag sein!
Der letzte Satz des obigen Kommentares gehört sicher nicht zu dieser Aufgabe, sondern zum gesamten ortho-Urdruckangebot.

Wenn der wSg8 - wie oben vorgeschlagen - nach d5 versetzt wird, steht der sK im Schach! Mit wSg8->d7 löst nur 1. Se5!

Gewinn
(St. Eisert). Trotz des Hinweises auf die Remisfassung (10825) erwies sich diese Studie als viel zu harter Brocken für die Löserschaft! Um zu gewinnen, muß unbedingt der schwarze Bauer auf g7 unschädlich gemacht werden. Die Eroberung dieses Bauern kann nur durch forcierte Drohungen erreicht werden, da er sonst einfach vorrücken kann. Also 1.Tb7! Lg1! Auf 1.Lf2 wäre Ke4 schon entscheidend 2.Tb5! Droht in bekannter Weise die Diagonale mit dem Manöver Kc4/Tc5 zu unterbrechen, auf 2.Tb3 würde 2.- Sc5 3.a7 Se6 das Remis erzwingen. 2.- La7! 3.Kc4 Sf4 4.Tb7! Le3! Nach 4.- Lg1 könnte sich Weiß einfach auf g7 bedienen, doch jetzt... 5.Tb2+!! Hier sei nochmals an die Remisfassung erinnert - nach 5.T:g7 wäre die Ausgangsstellung dieser Studie mit vertauschten Farben auf dem Brett, und 5.- Kh3!! würde Remis halten. 5.- Sg2 Auf 5.- Kg1 oder 5.- Kh1 würde das Manöver Tb5/Tb7/T:g7 ebenfalls entscheiden. 6.Tb5! Wieder droht die Unterbrechung der Diagonale. Nicht ausreichend wäre 6.Tb3 Lf2 7.Td3 Se3+ 8.Kb5 Lg1 9.Td4 Sf5 10.a7 S:d4+ 11.Kc4 g5 12.a8D g4 und Schwarz errichtet eine Festung. 6.- La7 7.Tb7 Lg1 8.T:g7 Jetzt kann endlich auf g7 genommen werden, auf 8.- Kh3 gewinnt wegen des nun abseits stehenden schwarzen Springers am einfachsten 9.Kb5.
play all play one stop play next play all
siehe die Verbesserung unter P1404354
Anton Baumann: Der Hinweis: nach 5.T:g7 würde Kh3 Remis halten stimmt nicht!!
6.Kb5 und W gewinnt nach Nalimov in 36 Zügen!
Vergl. P1008871 (Schwalbe-Aufgabe 10825) (2021-11-10)
Anton Baumann: Verbesserungsvorschlag des Autors um den Dual 5.Txg7 auszuschalten:
sBg7 nach g6, wTb1 nach b5 (vergl. 'Die Schwalbe' 02/2005 S.51, bzw. 04/2005 S.114).
Diese Korrektur ist unlösbar; Schwarz hält nach 1.Tb7 Lg1 2.Tb1 Ta7 3.Tb5 (Zzw.)Kg2! 4.Kc4 Sf4 5.Tb7 Lf2 6.Tc7 g5 7.Tc5 Lxc5 Remis. (2022-09-15)
Felber, Volker: Zu den Kommentaren in seiner Aufgabe schreibt der Autor:
„Wegen des Kommentares von BAUMANN habe ich die Quellen studiert. P1404354 steht erstmals in Die Schwalbe 2009, Heft 236, Seite 116.(so arg wichtig ist das aber nicht!) eine Korrektur der von BAUMANN auch zitierten P1008871 steht erstmals in die Schwalbe 2013, Heft 262, Seite 225 (10825v) und später dann auch in der "Schachnovelle". Die Korrekturen waren also schon Jahre vor der Mängelkritik vollzogen.

Ich bin WILTS durchaus für die Erfassung meiner Stücke dankbar, habe das aber erst Ende 2021 bemerkt. Als Autor kommt man sich als dumm verkauft vor, wenn Fehler gerügt werden, die man längst behoben hat.“. (2022-09-16)

lt. A. Baumann die andere Forderung mehrere 'Schlüssel' zulässt. Ich bitte um Prüfung! (2024-03-10)

t/promotion only,
Erich Bartel: Im Dreisteiner 4 Umwandlungen in promotion-only-form. Ein toller Einfall!
Aus meiner Sicht allerdings keine AUW im klassischen Sinne, da die M öglichckeit der S-UW bedngungsgemäß ausgeschaltet wird. (2009-07-16)
Joost de Heer: An AUW is promotion to all regular pieces. In Cavalier Majeur, a nightrider is the regular piece, not the knight, so a knight promotion would actually be a fairy promotion.
So in my opinion this is an AUW, just like e.g. promotions to LE, PA, VA and MA in LeoChess is an AUW. (2021-05-27)
A.Buchanan: Yes clearly we must be able to scale the notion of AUW to the fairy world, and Cavalier Majeur is an established format, even in Popeye, avoiding any excuse that one is simply picking the fairy units one by one like widgets. Not sure why Erich is so grudging. (2021-05-27)
Henrik Juel: There is no real disagreement, I think
Erich says that this is not an orthodox all-promotion
Joost and Andrew say that it is a fairy all-promotion (2021-05-27)
Joost de Heer: @Henrik: I'm saying this is NOT a fairy AUW, so exactly the opposite.
AUW: Promotion to all pieces that are present in the begin position (and for Cavalier Majeur that's QRBN, and not QRBS).
Fairy AUW: Promotion to all pieces that are present in the begin position, plus all extra fairy pieces that are allowed.
In a CM composition, promotion to QRBS is not an AUW (since in CM the knight is a fairy piece!), nor is it a fairy AUW (the nightrider promotion is missing). (2023-03-23)

0.2.1...
Yuri Bilokin: you can see h#3 1.b2 Ka3 2.b1=R Ka2 3.Rc1 Se3# (2022-12-10)
Henrik Juel: I think it is cooked, because of the solution in 3.0 moves
It might be saved by changing the stipulation to something like
h# in excactly 3.5 moves, 2 solutions
I am surprised to find that both Popeye 4.51 and 4.61 miss this grave flaw (4.79 is no better)
So Popeye is no better for helpmates than Euclide and Natch are for proof games: You must test for shorter solutions explicitely; the programs do not provide them (2022-12-10)
A.Buchanan: Hi Henrik I’m a bit confused. Are you saying set play for a helpmate is always a cook? For a h#3.5, Popeye certainly picks up all solutions of the form h#2.5 but will only find a h#3.0 if set play flag is enabled. Helpmate analyser has the same philosophy. When they talk of “short solution” for helpmate, I think they mean premature ending not “delayed start”. (2022-12-10)
A.Buchanan: A premature ending must still end with a white move, which is why the engines only pick up those solutions which differ from the intended one by a whole number of moves (2022-12-10)
A.Buchanan: I agree the sloppy old Codex is ambiguous on this, as on many things, but this is certainly the interpretation that I believe others hold. If not, it would be impossible e.g. to begin a solution with a pure tempo move (2022-12-10)
Ladislav Packa: Andrew, I agree with you. In this particular problem, for example, just add bPb5 and it's a correct H#3,5*. (2022-12-11)
A.Buchanan: Hi Ladislav. Thanks but I don’t think you do agree with me. I say the current problem is fine indeed excellent. No fix is needed - adding that unit loses miniature and means one mate is no longer ideal. I tried to explain to Henrik why engine developers take the stance they do, but he hasn’t responded. To me this is not a controversial point - it’s kind of obvious (2022-12-13)
Henrik Juel: Hello Andrew
You are probably correct in saying that the helpmate solvers only search for solutions with the right side starting (e.g. White in a h#3.5) (unless the set play is explicitely asked for also)
I still think that here the solution in 3.0 is a cook, and Ladislav seemms to agree... (2022-12-13)
A.Buchanan: Hi Henrik. Would you say that a #2 where the diagram position is a zugzwang is unsound? It’s exactly the same logic as you are applying here. I’m a bit surprised you take this position. There is no artistic gain - it merely prevents blocks cool stuff e.g. any key in a h# from being a tempo move. My view is that across all genres, set play is a completely separate concern from short solutions. A composer is allowed to constrain the problem by saying implicitly who has the move. With respect, I think Ladislav is confused. (2022-12-13)
Ladislav Packa: Andrew: it was just an example, I didn't want to fix the problem. It was to support your claim that the shorter solution is something like a set play.
Henrik: you are not right. I am giving a specific example, P1355854. It's really humorous that this problem was originally kicked out of the tournament because it also has a shorter solution h#3.... (2022-12-13)
