Ein sehr circetypischer (hinsichtlich der Spiegelung) Mechanismus mit UW/Blockwechsel. Eine prima Aufgabe (EB)!
MR: Die Dualvermeidung beim Block e(d)3 sowie der sUmwandlungs- und der wFunktionswechsel sind brilliant miteinander verwoben. Leider bleibt der Mattzug von der ganzen Spiegelfechterei unbeeindruckt.

Henrik Juel: The position can be reached in 18.0 moves: the first 3.0 as above, then Black plays as above, while White plays f3 and 14 tempo-moves like Sh3-g1.
Changing the stipulation to 'Proof game in exactly 18.5 moves' may rectify the situation.
The intended White play is very nice: Roundtrip by Ke1, needed by the triangulation on e3-f4-f3-e3, and roundtrip by Sg1, which screens on d4. (2011-03-14)
A.Buchanan: The preferred trick in such situations is to add an extra half move. So I'd try 19. ... Lg8: is that sound? (2017-09-14)
Henrik Juel: I tried to test 19... Lg8, but Euclide was too slow (2017-09-14)
Mario Richter: rawbats say that appending 19. ... Lg8 allows many alternative solutions, e.g. 1. c3 h5 2. Da4 h4 3. Dc6 dxc6 4. f3 Lf5 5. Sa3 Lh7 6. Tb1 Dd4 7. Ta1 Da4 8. Tb1 e6 9. Ta1 Se7 10.

rawbats also says that Henrik's suggestion of changing the stipulation to 'Proof game in exactly 18.5 moves' will make the problem correct. (2017-09-18)
Mario Richter: I forgot: ... but since "loss of tempo" is the theme of the problem, this change of stipulation is IMHO not an option here. (2017-09-18)
A.Buchanan: Thanks Mario, and I agree with you about the aesthetics of change. After posting my Lg8 suggestion, I did regret it because it's doubly suspicious. Firstly, the bishop can sneak past bRh8; secondly it takes the bishop's eye off d3 & c2. A more serious guess is to replace the last black moves by 16... Rh6 17... Sf8 18... Rf6 19... g6. This might fail for what in my head I call the "jigsaw" reason: that the known sub-chains of moves no longer mesh together in a unique way, but I don't think it fails for any other reason. Prove me wrong, stout rawbats! :D (2017-09-18)
A.Buchanan: Sorry Henrik I should also have said thank you for trying to validate my dumb earlier suggestion :-) (2017-09-18)
A.Buchanan: Typo, I meant: 16... Rh6 17... *Sh8* 18... Rf6 19... g6 sorry :( (2017-09-18)
Mario Richter: with the last black moves changed to 16... Rh6 17... Sh8 18... Rf6 19... g6 (final pos: 7n/pppnkp2/2p1prp1/2b2b2/q2r3p/2P2P2/PP1PP1PP/RNB1KBNR) rawbats thinks the problem is correct (2017-09-18)
A.Buchanan: Thank you, Mario. Obviously the composer could easily have fixed this if he was aware of the concern. His KS round trips are fantastically meandering, and the precise W&B play are very interdependent. I am amazed that there is only one composition in PDB by this top level composer, so I've found another to post quickly. He has a website http://open.mixi.jp/user/10857363/diary, with lots of erudite commentary in Japanese on top Western retros. Thank you, google translate! (2017-09-18)

Judge's comment [Silvio Baier]: "Two cross-captures with the same type of captured pieces (QR) are combined with a cross-capture of two black rooks. This is not the highest number of cross- captures in an orthodox proof game (see e.g. P1003984 for comparison), but the pairs are very harmonious and the additional white Q-Pronkin is difficult to implement, and especially the motivation of the promotion of Pa2 is very deep. The check in the diagram position does not detract, since g2-g3+ is also possible with respect to pure retroanalysis."
A.Buchanan: Great problem, but I disagree with the last sentence in Silvio's comment. The alternative at the end g2-g3+ would force an obtrusive bishop. If the composers could have figured out how to do this without the final check, they obviously would have. (2017-09-18)
Henrik Juel: I also like this proof game very much
It seems the kind of problem that is most readily solved by hand; the missing [Lc1] and the missing black rooks might prompt the suspicious solver to consider cross-captures
Euclide did find the solution, but after a long time, and he was not able to verify uniqueness within an hour (2017-09-18)

Judge's comment [Thomas Brand]: "This elegant proof game seems me original enough compared with Hashimoto's Probleemblad 1999, 3rd Prize, (PDB P1000642), even though the theme is not doubly set. The only missing white man is a Rook captured at e6, but Ra1 could not leave home."
Henrik Juel: The white plan is obvious, and Black ensures uniqueness by putting his men to be captured on squares, where White can go anyway, and by a late king's walk
This proof game is an enjoyable solving object showing that man can beat the computer; Euclide was still trying to find a strategy (a list of moves, possibly infeasible, that leads to the diagram position), when I had solved the problem and written the present lines...

- Author – Kurt Keller (Ulm, Germany)
- Für den Ostergruß wurde das Problem offensichtlich zu früh gebracht. Das Problem selbst ist jedoch für die Weihnachtszeit geeignet, da die beiden Kreuze auch als Weihnachtsbaum oder Kerze betrachtet werden können. (The problem was obviously brought up too early for the Easter greeting. However, the problem itself is suitable for the Christmas season because the two crosses can also be considered a Christmas tree or candle.) Vergleiche (Compare) P1388082

Henrik Juel: I think that the twinning is more clearly described by something like

James Malcom: Is this fully C+ then? (2021-01-27)
Henrik Juel: No, only the first 31.5 moves are tested OK (2021-01-27)
James Malcom: No Henrik, as in is the entire problem testable. (2021-01-27)
Henrik Juel: I guess that testing the entire problem would take an unreasonably long time (2021-04-06)
A.Buchanan: It might be possible these days: the motivation for stopping at 31.5 is that the promotion theme had been demonstrated by then. But there’s still e.g. bSb8 as random impostor (2021-04-07)
Moldenhauer: Computerprüfung: C+ Stelvio 1.11 50:24:34 Stunden.(hh:mm:ss)
