A.Buchanan: @Mario: this is the only one of 19 Baird retractor solutions where I couldn't kick the animation engine into action. It basically doesn't like the uncapturing unpromotion. Any ideas? (2019-2-8)
A.Buchanan: I just looked at the Leeds Mercury publications. (2019-2-8)
Henrik Juel: Have you tried to write the retraction like this, Andrew:

Henrik Juel: or

Henrik Juel: The previous play includes:
White pawns captured all missing black men with a5xb6, b4xc5, cxd, f2xe3, g5xf6, and h4xg5 (so White may not uncapture with an officer, nor may he uncheck with e5xf6 or f4xg5)
Black captured nothing and promoted on a1
Fine idea, accentuated by a close try, and perfect construction (2019-2-28)

Klebe zwei Brettränder so zusammen, daß eine Mattstellung entsteht!

Zusammengeklebt werden müssen der linke Brettrand und der obere Rand (a1->h8, a2->g8 usw.), Der sK steht nun im Doppelschach durch wTg6-a6(=c9)-c5+ und durch wLb3-a2(=g9)-c5+, d.h. Schwarz ist matt. (TK)
Henrik Juel: Forming a cylinder board seems too simple (and it doesn't give a mating position)
So I would guess that you twist the board before gluing, getting some kind of Möbius board
Can someone give the intended solution from feenscach, please (2019-2-27)

(Not h7-h8=D+ as temptation, but straight Dh7-h8+! and clever use of the tempo-moves of black a- and white a- and b-pawns.) (2013-10-1)
Henrik Juel: Analysis of the pawn play
The only white capture was cxDd or exDd
The four black pawns not on row 7 must all have captured (also sPg3, because wPg6 did not), but they did not capture white pawns, so the three missing white pawns must have promoted; hence [Pc2] (which could not have promoted) now stands on the d-file, the white capture was cxDd, and White promoted on a8, e8, and h8 (so [Pa7,e7,h7] have captured)
The missing black pawn promoted to L on a dark square, and now we can determine the black pawn play: a4xb3, c2-c1=L, e5xd4, g5xf4, and hxg
It is unusual to see such a complicated pawn play analysis, and it gives the start of the retroplay (following the initial unchecks): unpromote wSh3 on a8 (6 S-retractions suffice, although the solution above uses 8), then uncapture a4xb3 (2019-3-1)

In einer Schachpartie spiegelte Schwarz mit jedem Zug den vorangehenden weißen Zug (an der mittleren Waagerechten). In der Partie kam ein en passant-Schlag vor. Wer gewann und welche Art(en) von Steinen griff(en) den gegnerischen König in der Schlußstellung an?

Weiß gewinnt. Der ep-schlagende Bauer setzt matt. Einige beispielhafte BP s. oben.
Nikolai Beluhov: English stipulation: "In a game of chess, every one of Black's moves precisely mirrored the previous move by White. One of the moves in the game was an en passant capture. Who won and what was the piece (or pieces) attacking the opponent's King in the fi nal position?" (2011-1-9)
Henrik Juel: When White captures en passant, Black cannot mirror the move (because last move was not a pawn double-step), so he must be mate
The mate cannot be a discovery mate (this would entail the kings being illegal neighbors on rows 4 and 5, or a previous white check was illegally ignored by Black), so the white pawn directly attacks black king in the mate position (2019-2-27)

Henrik Juel: Analysis of previous play
White played axb-b8=L, bxa-a8=L, cxd, exd, gxh, and hxg, and captured the remaining missing black man [Pf7] on its file with an officer
Black never captured and promoted c1=L and, unless axb was axPb, b1=Y

Fine first retraction (the meaning of which is only clear 11 moves later) and nice unchecking tour by wSc2 to and back from f5, where it uncaptures to prevent wLg6 from guarding e4
The formal stipulation solution is C+ by Popeye 4.61 (2019-3-2)

wLb8 is promoted, so White captured all missing black men with axb, b2xc3, and e5xd6, and promoted on f8
Black captured [Ph2] on its file with an officer and fxg
The added man must be wLb4 or wSb4 and last move was Lc8-d7+ (2019-3-4)
Henrik Juel: Thanks for posting the animation, Mario
The addition must be wLb4, because later we must unpromote it on f8, and a wS would be too slow getting there (2019-3-4)

letzter Zug des sK war Kb5-a6

Löserkommentar M. Richter: Mit einem unvorbelasteten Blick auf die Stellung könnte man meinen, daß der sK zuletzt sowohl Ka5-a6 als auch Kb5-a6 gezogen haben könnte. Es stellt sich aber heraus, daß der letzte Zug des sK eindeutig bestimmt ist:
Der schwarze Doppelbauer auf der e-Linie kostet zwei Schläge, was alle fehlenden wSteine erklärt. Insbesondere hat also der sBh7 nie die h-Linie verlassen. Ferner hat nach der Rücknahme wLc8xYb7+ Weiß nur noch drei Schläge übrig, wovon zwei zur Erklärung des wDoppel-BB auf der c-Linie benötigt werden.
Der wBh2 konnte also nicht auf die f-Linie gelangen und muß daher auf g8 umgewandelt haben, was den letzten fehlenden schwarzen Stein 'verbraucht'. Weder der wBg2, der deshalb auch auf g8 umgewandelt haben muß, noch sein Kollege von f2 haben ihre PAS-Linie je verlassen, die Rücknahme sBfxe kann also erst erfolgen, wenn der wBf6 mindestens bis f4 zurückgerutscht ist; sBg6xf5 kann erst zurückgenommen werden, wenn beide Umwandlungen auf g8 zurückgenommen wurden.
Um eine schwarze Retrozugnot abzuwenden, muß Weiß möglichst schnell auf g8 entwandeln, weil dann durch wBhxg ein Stein aufs Brett zurückkehren kann, der dann auch gleich als Schild auf a5 fungieren kann (die einzige Möglichkeit, das Knäuel am Damenflügel aufzulösen). Letzteres kann nur ein Springer leisten, für den ersten Rücknahmezug Lc8xYb7 bleibt als Schlagobjekt somit nur noch die Wahl zwischen sT und sL - aber auch das ist rasch geklärt, denn nachdem der sS a5 besetzt hat, geht es mit der Stellungsauflösung nur weiter mit wTa4-a3,sBa3-a2,wBa2xb3. Zu diesem Zeitpunkt steht der wK auf b4, ein auf b3 entschlagener sT böte illegales Schach, also wird dort ein sL entschlagen. Damit ist das Bild komplett, und es ergibt sich:
1.Lc8xTb7 h3-h2 2.Sh6-f7 h4-h3 3.Sg8-h6 h5-h4 4.g7-g8=S h6-h5 5.g6-g7 e4-e3 6.h5xSg6 Sf4-g6 7.c3-c4 Sg2-f4 8.h4-h5 Se3-g2 9.h3-h4 Sc4-e3 10.h2-h3 Sa5-c4 11.Kb4-a4 h7-h6 12.Ta4-a3 a3-a2 13.a2xLb3 Ld5-b3 14.Kb3-b4 Sc4-a5 15.Tb4-a4 Kb5-a6! (nur so läßt sich ein notwendiges Tempo gewinnen) und weiter z.B.16.Ta4-b4 Ka5-b5 17.Tb4-a4 Ka6-a5 18.Ka4-b3 Se3-c4

Nicht schlecht, insbesondere hat mir gut gefallen, daß der einleitende Entschlag nicht wie oft üblich (z.B. bei der Schwesteraufgabe 14696 [P1185292]) offensichtlich ist, sondern sich nur erschließt, wenn man schon eine konkrete Vorstellung von der kompletten Auflösung hat.

Motto: "Heart and arrow"
Originalforderung 1.White played last, retract his move 2.Black retracts his last move 3.Black plays so that-- 4.White mates,-- the final position to form an arrow
A.Buchanan: Mario: is this a conditional problem? I.e. are there any other solutions which are not arrows? (2019-2-8)
Henrik Juel: Yes, this is a conditional problem
Without the condition that the final position resembles an arrow, 1.Dd8 could be 1.Da7,Db8,Dc7 etc., anywhere except where she guards e4 (2019-2-8)
Henrik Juel: Of course, Db6 may also not capture the guarding wPb5 or give check with 1.Df2+
But the condition is not well defined, although most people would agree that 1.Dd8 forms the 'best' arrow (2019-2-8)
Mario Richter: Yes, definitively a conditional problem.
In testing the problem, I let 'rawbats' produce all solutions and then filtered out those where the final position looked like an arrow (mainly something like "--" or "--").
Without the "arrow-constraint" there are tons solutions, eg. R: 1. Sg6xBe7 Da7xTb6, dann 1. Tc7-c6 Tb6xc6# or R: 1. Ba4xLb5 Bd5xTe4, dann 1. Db6-c5 Te4-e6# or R: 1. Kf4xLf5 Tb7xTc7, dann 1. Lf5-e6 Sf6-e8# (2019-2-8)
Mario Richter: I forgot that > and < are not allowed, my previous comment should read: ... mainly something like ">-->" or "-->" (2019-2-8)
A.Buchanan: Rather a nice stipulation: make the diagram look like something particular (2019-2-8)

Motto: "Submission"
Originalforderung 1.White played last, retract his move 2.Black retracts his last move 3.Black plays so as to enable-- 4.White to mate
A.Buchanan: Mario: thanks for putting in solutions for these.
(1) I guess they are HC+ through rawbats, with manual validation that there are no non-local reasons why a particular unmove is illegal. You should show these in computer test: if you are agreeable I can adapt my screen-scraper to make those updates automatically for any classes of problems you wish to cover.
(2) It seems that in order to get the animation to work, I must trigger the PDB re-evaluation function by edit the solution without doing anything. The PDB animation engine does not accept B (for pawn) except where absolutely necessary to indicate a B has been uncaptured, so I have removed those and then it runs smoothly. (I.e. all red background to offending moves disappears.)
(3) In some cases, I have added "conditional problem" where Baird said e.g. "Black checks", "no queens" etc. (2019-2-8)
Mario Richter: In this case, no manual "post-processing" was necessary, the problem is really C+.
In some other cases - like eg. the ones you mentioned ("Black checks", "no queens") filters have been used to cover the additional constraints, but not to add knowledge that 'rawbats' doesn't have, so they still are C+.
A HC+ comes into play eg. if rawbats doesn't "see" that a certain uncapture isn't legal and a filter is used to cover this situation ... (2019-2-8)
A.Buchanan: Baird's problems probably don't require retro logic, but is rawbats checking that any position is indeed legal i.e. can be derived from game array. Or is it just checking there are no obvious factors indicating illegality? (2019-2-8)
Henrik Juel: A few kinds of illegality are easily checked, like illegal pawn configurations (e.g., wPa2a3b2) or triple checks, but there are too many kinds of illegality (e.g., wPa2b3c2 wTb2, sKa1) for anyone to program a general legality checker (at least so far)
Otherwise we would have access to solvers for illegal cluster problems and resolution retros (2019-2-8)
A.Buchanan: @Henrik well exactly this is my point. Mario had said "the problem is really C+" but I don't think it is, although for Baird the gap is insignificant. (2019-2-8)

4.Th1-h2 Sg4xh2 5.Ba2-a3 Sh2-g4 6.Bh3xg4 Bh7-h6
and identical to the first 6.0 moves of the intended solution
Why could the subsequent triple repetition not be achieved by rook moves?
Probably because the position after 7.Ta2 Tb8 8.Ta1 Ta8 is not considered to be a repeated position, as the castling rights have changed (2018-12-25)

other black captures: c7xd6, d5xe4, g7xh6, h7xg6 (to let h2 promote to L)
Black Queen must make a triangle to let everything work out (2012-12-12)
Henrik Juel: Results of pawn play analysis:
All captures were pawn captures
White captured a5xb6 and bxc, and promoted h7-h8=L
Black captured c7xd6, d5xe4, exPf, g7xh6, and h7xg6, and promoted a2-a1=D
Resolution plan:
The NW cage is completely locked, and the only way to open it is to extract sDh8 somehow, unpromote her on a1, retract the resulting pawn to a6, and then retract a5xb6 (2019-3-6)
