paul: C+ pour les premiers dix coups (Popeye). (2011-09-17)
Sally: Die Reihenfolge der Züge ist festgelegt, aber eine bestimmte Thematik wird nicht gezeigt. Dieser Sachverhalt scheint sehr zur Schwierigkeut der Aufgabe beigetragen zu haben. Es gab nur 2 Löser! (2017-09-06)
A.Buchanan: Up to 10.5, the solution is unique (Jacobi, 2.5 hours on my little laptop). Maybe someone here can push it all the way? (2021-11-26)
Henrik Juel: Natch 3.1 could not even find pos. 1 in several hours (2021-11-26)

A.Buchanan: The term "retro" is jungle not garden - that means we should not expect an axiomatic definition. The current problem is a case in point. Case law has established that neither simple employment of the castling convention nor existence of check are sufficient to make a problem "retro". But all this problem has is the quirky use of Codex Article 15 to force BTM. So I think this problem has to be retro. The key point is that nothing hinges on the retro-ness. If the problem included 50M or DP, then one would expect a more solid foundation. As it is, all we need is the free direct mate in 1 that comes as part of the retro paradigm. (2021-11-26)

Henrik Juel: 41.5 moves is a very old record
The current record length for proof games is 58.5 moves in a problem by Pronkin, Frolkin & Keym, problem C, p.7 in Die Schwalbe, heft 283, February 2017
The former record was 57.5 moves in a problem by Pronkin & Frolkin, Die Schwalbe, 1989 (V) (2017-09-06)

P0000736 plus the 1.5 obvious moves. Why did he stop? :-)
Henrik Juel: He probably stopped because
1. he was afraid of cooks
2. the Homebase theme was unknown in 1979
Is the extension to 8.5 C+? (2021-11-25)
Olaf Jenkner: This version is in my opinion 100 times better than P0000736, a homebase with 9 missing men in only 8.5 moves.
Is there a record list of proof games "homebase with x missung men" in a minimum number of moves? (2021-11-25)
A.Buchanan: Thanks Olaf for your kind words. I don't think there is such a list. PDB has today 19 homebase unique PGs which are no longer than this with no fewer captures. Most are 9 captures but P1000453 by Le Gleuher alone manages to get a 10th capture. He also manages the shortest (6.5 moves P1000944), with 7.5 moves by Mintz P1329742 as runner-up, and 4 others in 8.0. To be fair, the aesthetic for the Future Proof Game gang has generally been to *minimize* the number of captures. Except for Mintz and one other, all involve promotions. (2021-11-26)

Henrik Juel: Thanks for pointing out this cook, Michael
I have not seen something like that before, so maybe I should write '... found no flaws in 13 moves' or similarly in the future
Of course Popeye can 'handle' this with 'stip s#12 opt non 1 1 thr 0', but using a dedicated solver is easier (2022-03-29)

Henrik Juel: White king corrects the tempo by passing e8, the only square where he is safe from Lg2
He does a long march, but not a round trip (2023-08-15)

msterkowiec: Maybe it will be interesting (for me it is) that this position can be easily transformed into #34. This is because pawns wh.a5 and bl.a6 are only to avoid later/minor dual (there would be also 9.Ka5 without these pawns).
If remove these pawns (and accept minor later duals) and add black pawn a7 (8/3p3p/3P4/8/p4N2/rpK1p1pp/1p2Bkbr/bR5n) we would have the following #34: 1. Kd4 Ra2 2. Ke5 Ra3 3. Kf6 Ra2 4. Ke7 Ra3 5.

A.Buchanan: It's curious that if we shift sK to e8 (i.e. make the position fully homebase) then it is sound as BP in 6.0! The magic of homebase! :) I don't know if it was a typo - maybe someone can check the magazine archive? (2021-10-19)
A.Buchanan: WinChloe & YACPDB don't know this composition. (2021-10-20)
Mario Richter: No typo, the position with black Kd8 was intended, the cook was found by the 'Schwalbe'-solvers (Heft 71, Oktober 1981, p. 349) (2021-10-21)
