See P1338946 cooked.
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)

Reto: This is now the new record for the longest computer tested SPG. Strategy seeking takes up all the time, playing the 800 strategies on the other hand is done within a few seconds. (2023-08-11)
Reto: With the upcoming v1.6, this is solved by Stelvio in around 20min. The improvement is due to the fact that the cage in the south-west is now detected (either the wRa1 is captured inside the cage or the wBc1 is captured at home) (2023-09-02)

Henrik Juel: Following R: 76.h3xLg4, the resolution could continue with
Retract wKc8 to b5, sLg4 to c8, b7-b6, sSa8 to g8, wSa4 to g1, wKb5 to e1, sLb8 to a5, b6xTc5, wTc5 to d4, sKa1 to b5, a2xTb3xDc4+, etc. (2020-08-13)
Henrik Juel: A little analysis may be in order
Pawns captured all missing men
Kb3 is now confined to the SW corner, but if we retract b3xc4 he is locked in for good, so [Lc8] was captured on g4
Before we retract h3xLg4, sLg4 to c8, and b7-b6, wKf8 must be liberated
The plan for this is: Retract wKg8-f8, sTg1 to f8, sTe7 out, wTf8 out past the sT, wKg8 to e7, sT to h8, wT to e8, and further as per my old comment (2022-01-22)

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)
Arnold Beine: Alybadix und Jacobi kennen/können Haaner Schach nicht. (2022-09-19)

Arnold Beine: Hier stimmt etwas nicht, obwohl Stellung und Lösung mit der Originalveröffentlichung übereinstimmen. Der Zug 3.Db4 muss falsch sein, denn dann kann 23.Lb4 nicht gespielt werden. Stattdessen 23.Lg7 zu spielen macht auch keinen Sinn, denn dann wäre die wDb4 am Ende nicht am geforderten fünffachen Schachgebot beteiligt. Stattdessen 3.Dd4 usw. zu spielen würde am Ende zwar eine fünffache Bedrohung des sK bedeuten, wäre aber auch Matt, was der Forderung widerspräche. (2022-10-20)
SCHRECKE: 3. Dd4 ist kein Matt, da die wD paralysiert ist! (2022-10-20)
Arnold Beine: Am Ende wird die sD geschlagen und damit sind alle weißen Damen aktiv - also Matt! (2022-10-20)
SCHRECKE: O.K., dann müsste halt statt des "+" ein "#" stehen. (2022-10-21)
Arnold Beine: Dann wäre das aber eine ganz andere Forderung, weil nicht mehr ein "Mehrfachschach", sondern ein "Matt mit einer zusätzlichen Einschränkung" gefordert wäre. Die Forderung müsste dann "ser-#26 durch Fünffachschach" heißen, und am Ende der Lösung müsste "26.Lxd2# durch Fünffachschach" stehen.
Ich zweifle, ob das im Sinne des Autors gewesen wäre, denn die Aufgabe wurde gemeinsam mit neun weiteren Aufgaben von ihm auf Seite 253 der PK 178 veröffentlicht - alle mit unterschiedlichen Mehrfachschach-Forderungen, wie man auch in den jeweiligen Lösungen erkennen kann.
Mit der Forderung "ser-#" (ohne Einschränkung) wäre die Aufgabe bereits in 2 Zügen lösbar: 1.Dd7 2.Te4#. (2022-10-21)
SCHRECKE: UH ist laut "Schwalbe" verstorben, er kann sich der Sache leider nicht mehr annehmen. (2022-10-21)
HBae: Habe Lösung korrigiert: 3. Dd4! (2022-10-21)

Vaclav Kotesovec: As a composer, I would have preferred to place the white king on h5 (and ser-!=112) with multiple switchbacks, but I understand that the authors were probably more concerned with the length record. (2023-04-09)
James Malcom: That is quite the dedication to computer testing! (2023-04-10)
Vaclav Kotesovec: This problem was one of a number of problems I chose to test the new version 4.2c of Gustav by Olaf Jenkner. I always test several problems in parallel, so even though the testing times may seem long (and in the case of this problem it was rather an exception), on average it takes no more than a week to test one such problem, so I get some results almost every day. The most time-consuming problems are, of course, correct ones, and cooked ones are usually discovered much faster. I consider the fact that this problem has been completely tested as another step on the very limit of the possibilities of current computer technology. (2023-04-10)

Joost de Heer: This is probably Kriegspiel? If there are no black pieces, the knight path on moves 25/26 can go over f6 as well. (2022-10-25)
A.Buchanan: Good catch, Joost. The black units (because of bK) are necessary. I haven’t heard the term Kriegspiel used to describe this. (2022-10-25)
Henrik Juel: This is a series proof game (where only White moves, and he may not check with an intermediate move)
I see no relation to the fairy condition Kriegspiel (2022-10-25)

Bitte Olaf! (2023-09-01)
A.Buchanan: This problem and its antecedant are NOT cooked. They are non-unique proof games, and there is no intention of uniqueness. Whilst it's useful to identify a shortest solution, it is disrespectful and confusing to wave around the terms "C-" & "cooked". When we have verified that this problem has no solution in 18.0 or 18.5 moves, we can mark it as C+. (2023-09-02)
Olaf Jenkner: That's quiet confusing. See P0000404 with stipulation "BP in 45,0". The keyword is "Unique Proof Game".
This problem has the stipulation "BP in 19.5". The keyword is "Non-Unique Proof Game".
I don't believe that the dot makes the difference. (2023-09-03)
Henrik Juel: One way of limiting the confusion is to change the stipulation to
Length of shortest proof game?
C+ then means that this length is indeed 19.5 moves (2023-09-03)
A.Buchanan: A root problem is that animation engine reads the stipulation to decide what to do. (AND the details are undocumented.) So if we change the stipulation to something correct, we will lose the animation. Also, there is no Originalforderung field to keep track of the composer's intent. The comma dot is another linguistic challenge which could be addressed if we had multi-language support for stips like we do for source, composer, keyword & fairy piece. Obviously I'm very grateful for Gerd's work, but he has given no indication when, if ever, he will restart serious development work on PDB, so in the meantime we need to muddle through. In the meantime, the best we could do is rework the stipulation to add "(non-unique)" or "how many solutions?" etc. This edit can be done by screen-scraping in an automated way, if we can agree the principle (2023-09-03)
