Die Umwandlung aller 16 Bauern in schwarzfeldrige Läufer bzw. in Türme erforderte alle 8 Schlagfälle, und zwar so, daß alle Umwandlungsfiguren auf schwarzen Feldern entstanden. Deshalb kann zuletzt auch keine schwarze UW erfolgt sein.

Joaquim Crusats: Can anyone explain the intention? (2013-01-06)
Henrik Juel: The eight white pawns captured the four missing black officers and promoted on b8, d8, f8, and h8; the eight black pawns captured the four missing white officers and promoted on a1, c1, e1, and g1.
If White had the move, 1.Ta5+? Kxb4 2.Sc6+ Kc4 3.Tc5 would mate in three.
But Black has no last move, so he has the move and mates in three by 1... T3d2+ 2.Lexd2 Txd2+ 3.Kb1 Txc1# (2013-01-06)
A.Buchanan: This is one of a number of problems which had been given both "No legal last move for..." & "Whose move?" keywords. These should correspond respectively to two situations: (1) Codex Article 15 where we add or remove a single move from the beginning of the solutions, but the mating party remains the same. (2) A kind of one-sided duplex, where who moved last implies who delivers the mate (or other final move).
So at most one of the two keyword forms can ever logically apply to a problem. Therefore I have removed the incorrect "No legal last move for Black" keyword.
We might replace "Whose move?" by "Halfduplex", which is related to the Popeye option. What do you think? (2023-11-28)
A.Buchanan: This is a nice problem. There are some final move duals for the actual solution, but all missing units are needed to justify promotions (2023-11-28)
Henrik Juel: Halfduplex is a bit too technical for my taste, although it describes the goings on well (2023-11-28)
A.Buchanan: Thanks Henrik - I'll leave the term "Whose move?" as it is then. (2023-11-28)

Mario Richter: Luboš Kekely (Slovakia) correctly points out that 1. ... Sf5! 2. 0-0-0 Sd6# is only a try and not a solution (last black move must have been by King or Rook, so the queenside castling is illegal).
I have changed the solution accordingly. (2023-03-10)

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)

Längste BP ohne Schach. Welches war der letzte Zug?
R: 5899. Kg2xTh1
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.
Compare P1331022
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)

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)

A.Buchanan: What's a polar echo? (2022-03-08)
Henrik Juel: Good question
It must refer to the two mate positions:
The bishops stand on e3,f3 and e5,f5; with the kings on f2 and f4, Black is mate, and with kings on f4 and f6, White is mate
In non-duplex problems echo/chameleon echo mates are pretty well defined (black king on same/different square color)
So polar echo is just a third type, maybe only occurring in duplex problems (2022-03-08)
A.Buchanan: Thank you, Henrik. A non-duplex mechanism for Polar Echo is shown by P1305339 & P1305340. (2022-03-08)

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)

A.Buchanan: I don't know what to do here. Clearly we can't disrupt the rook square, so maybe +sBf3 is best as Yuri proposes (2021-04-16)
Yuri Bilokin: It is necessary to decide what is better to break the rook square or the Ideal mate. (2021-04-16)
A.Buchanan: Ideal mates are cheap, but Th4-h3-g3xg4-h4# is a prize. (2021-04-17)
SCHRECKE: why not: +bPh3? (2021-04-17)
A.Buchanan: @SCHRECKE because the rook's movement in a square should not be motivated by capturing, and +sBh3 also blocks wT unnecessarily from h1 & h2. This problem does not appear in WinChloe, at least not in Canadian Chess Chat under this author (who has 891 total compositions - not gone through them all). Maybe he never fixed it. One clean idea is to replace wKf1 with sBg2. This is still an ideal mate. Then put +wKa1 if you must :-) (2021-04-17)
A.Buchanan: +sBg2 & wKa1 is sound, but maybe best to rotate the board as sB threatening to promote is perhaps unfairly distracting to solvers (2021-04-18)

A.Buchanan: Busy - will check these later. But Adrian I didn’t suggest bB but sB i.e. (German) black pawn not bishop (2021-04-19)
Adrian Storisteanu: I understood you fine (but I might have misplaced the text in parentheses). (2021-04-19)
A.Buchanan: With your latest Bb7 Re4 Kc2 / Kg6 Pc5e5, once might as well remove the two black pawns and replace with wPd6 (then rotating the board by 180 degrees). But surely this is not original, and indeed P0510694 by Ugren achieves full h#4. But Yuri has already corrected P0503631 by Krikehli to achieve the same thing! Time to give up - nothing new here.

Thema des TT ('The Problemist' 09/1992, S. 88): "... composers are required to combine 2 (or more) problems to make a distinct third."
(Im 'Problemist' haben die Teilaufgaben a),b),c) und d) die Labels: D,A,B und C.
PR Barry Barnes vermutet in seinem Kommentar zu diesem Problem, daß ein Computer bei der Erstellung geholfen haben könnte: "Essentially disparate parts (A),(B) and (C) come together as something quite new in (D). But note a minimal record: 5 pieces, cyclic absence of 2 of the pieces, 4 different series-demands, and only ideal mates! Was Holmes right in thinking that a later model of Prof Babbage's "engine" (Cambridge,1834) determined the solving conditions and lengths?"

paul: Compare with P0002278 & P0002279 (2010-04-30)
Mu-Tsun Tsai: This one is by far the toughest retro I've ever solved. Very little certain information can be determined by structural consideration alone, even with long and complicated argument. It took me five days to complete solving this. (2012-07-22)
A.Buchanan: @Mu-Tsun: that's an interesting data point - thanks for posting. (2017-09-07)
Henrik Juel: The current record is 58.5 moves in a proof game problem by the authors + Keym, Die Schwalbe 2017 (2017-09-07)
Henrik Juel: I just learned that the 58.5 move proof game has been cooked... (2017-09-07)
A.Buchanan: In retrospect, my earlier comment about "interesting data point" is a bit weak. It's actually great that for such an extreme problem, someone took substantial time to independently validate it. It's like doing science: people want to do their own new stuff, and are unwilling to take the time to validate what's already been claimed. This one has survived 30+ years, and maybe the use of constraints e.g. in Jacobi can eventually allow it to be HC+. (2021-05-29)
Olaf Jenkner: This problem is the current record, because P1338946 (58.5 moves) has been cooked. (2021-11-25)
Reto: This is C+ up to 51.0 moves with Stelvio 2.0. This ties the record for partial testing of an SPG. Took 1200 CPU hours of strategy seeking (finding 378 0+0 strategies) and another 13h of strategy playing these strategies. If this can ever be completely solved, then it needs to be the case that all strategies have 0+0 free moves, otherwise playing is utterly hopeless.
@Andrew: There is absolutely no way a brute-force based program like Jacobi ever stands a chance at solving something like this, no matter how many conditions you add. (2023-12-14)
