A.Buchanan: Some brave person should sort out the keywords for record retros properly. Here's a good example. The last move is Type B, but the first move question is Type A. The original stipulation (which I think is just about the first move?) should stand. The first move question is a *deemed* stipulation (new terminology) and allows us to leverage an existing problem, without creating a new version or editing the prior stipulation. This is particularly true here, since the problems are of different type. (2020-12-14)

TRD: "The point here is that every move of the game is strictly forced in order and kind, the longest such game existant at present. I expect this task to go much further."
Original stipulation was: "White here mated in two and noticed on examining his score that the mate was administered on his 17th move. What was the game?"
A.Buchanan: This is the earliest unique PG recorded in PDB, but Dawson implies earlier, shorter ones exist. Can any of these be traced? (2021-01-22)

Easy to see no last move for White. Moreover, Black just double-hopped to allow sD/wK to avoid retro-loop.

Black can have wasted only one move and so cannot have moved K or KR, which would require a second waste move returning to diagram. Hence Black is legally entitled to castle. Therefore White mates in 2 by: 1. Kh1! 0-0-0 2. Tc1, else 2. Tg8

Can Black play to avoid being mated in 2?
But both b3 and Rc8 seem to let Black escape (2023-04-06)

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)

Yoav Ben-Zvi (The Problemist, 05/2017): The key by the White queen crosses c4, a Critical effect that is negative as it prevents the mate by P-c4 in response to random moves by bNc5 and bBb5, and also crosses e4, an Anticritical effect that is positive as it allows the mate by Pe4 in response to the same random moves. Correction moves by bB in the Set play and by bN in the solution lead to reciprocal change of mates with those in response to the random moves.

James Malcom: This seems computer testable, excluding the minor duals that there are. (2020-11-18)
Olaf Jenkner: Yes, Gustav gives 65 duals in less than one second. (2020-11-18)
James Malcom: But seeing as how that is part of the intention, clearly, and this is still a widely accepted and reprinted problem, is it C+ with the duals in mind as allowed? (2020-11-19)
SP: Though many problems exist where unsoundness is part of the intention, such as separators in solving tourneys, this is obviously not the case here. Are you seriously suggesting that if Bláthy could show his idea without the duals he would not have done so? (2023-07-10)
Olaf Jenkner: It's an old question what C+ means.
There are promotion duals, triangle manoevres and other stuff what we call "tolerated duals".
In this case I'd think C+ means "computer confirmed the author's intention".
It's different from FIDE rules. (2023-07-10)

msterkowiec: I think it's worth noting that apart from minor dual 4.Qf2/Qg2 there are also some other duals in subsequent moves:
1) 6. Qc6 lub 6.Qb7 (this repeating manoeuvre can be done both via c6 and b7)
2) 7. Qa6+ lub 7.Qa4+ (this repeating manoeuvre can be done both via a6 and a4) (2021-11-20)
