See P1398939
Henrik Juel: Black captured b7xLc6 and axbxc; White captured [Lf8], e2xd3, and fxexdxc6xb7-b8=D.
Ke8 to b7, Th8 to b8, Kb7 to g8, Tb8 to f8, Da4 to b8 for unpromotion, -22.c6xDb7 Da8 -23.d5xLc6 Dd8 -24.d4 Lb7 -25.e3xTd4 Lc8 -26.f2xSe3 c6 -27.h5 b7xLc6, Lc6 to f1, f2xSe3 etc.
Black may not castle, because he already did.
It is not possible to avoid the early castling:
-11... Ka7 -12.Db4 Ka6 -13.Db8 Ka7 -14.D=b7 Kb8 -15.c6xDb7 Kc8 -16.d5xLc6 Kd8 -17.d4 Ke8 -18.e3xTd4 Da8 -19.f2xSe3 Dd8 -20.h5 Lb7 -21.h4 Lc8 and two white pawn retractions are missing (2012-07-23)
Yoav Ben-Zvi: The solution does not require a full analysis since if Black King and Rook never moved then Black is almost immediately in retro-stalemate. An alternative stipulation is "First move of Black King?". (2014-06-03)
A.Buchanan: Maybe there is intentional irony? (2014-06-03)
Henrik Juel: Nowadays composers are not afraid to use the real stipulation in this type of resolution retro, like 'Release the position'.
Formerly a formal stipulation was popular, like 'Mate in 1', with the real stipulation understood but not mentioned.
Here, the stipulation question may well be ironic, but you will get no solution points, if you just answer 'No'; you still need to explain how the position arose (2014-06-03)

Retracting the castling is the only way to give Black a retraction, e.g. Kc2-b3 (2020-12-01)

Henrik Juel: Typo: 2.Dxa5 Db7#. wTa1 is missing, I think (10+15). -1... c7 -2.g5 Sc6 -3.De7 Sb4, unpromote wD on h8, etc. (2004-03-18)
A.Buchanan: I agree Henrik and have made changes. A number of these problems have been marked "Weisz zieht an", which is inappropriate as part of the point of the problem is to deduce this. I think it's 2. c2-c3! not 2. g5-g6? or the cross-captured pawns become retro-locked. (2021-10-21)
Henrik Juel: 2.g5-g6 also works, because the only cross-capture is axb,bxa
White captured [Pd7] with an officer (2021-10-22)
Henrik Juel: HC+ Popeye 4.61 (2021-10-22)
A.Buchanan: If g5-g6 also works, then can’t we have both? I.e. White moved last. I would be surprised if this was TRD’s intention, given the others of this general style (2021-10-22)
Henrik Juel: TRD died in 1951, so someone else may have messed up the problem
FRC is not generally available after 1953, so I cannot check the source (2021-10-22)
A.Buchanan: WinChloe has 29(!) posthumous problems by Dawson - the latest in 1958, FCR's final year. The composition in question is not one of them. (2021-10-23)
A.Buchanan: PROOF OF COOK + SUGGESTED FIX
I agree with much of what you say Henrik.
Capturing history. Basically 3 possibilities for the Black pawns.
Notation: ~,o,| denote "cross-capture", "original" & "waylaid"(=captured on home file by officer).
1) a~b co d~e f~g. This implies either (wPhxg & bPh=X) or (wPh=X & bPh|)
2) a~b co d~e hxgxf f|
3) a~b co hxgxfxexd d|
Suppose WTM. Then R: 1. c6-c5 c2-c3 2. c7-c6 g5-g6 3. Sc6-e7 De7-b4 4. Sb4-c6+ Kc5-c4 5. Lb2-d4+ etc. Now we're free to uncapture wDh8 (or g8 for scenario 1), and any of the three pawn scenarios can work. No e.p. rights means a cook.
If we fix it by e.g. shifting wPg6-g5 then I think that fixes this cook, and also it means that there is no solution if BTM.
Is there any possibility for premature capturing hxg? Not by Bl because scenario 1 says bPfxg, and the other two scenarios rely on wPh=X. If by Wh, then there's no waylaying on d or f, so we are back to scenario 1, but bPh is blocked from promotion, so that won't work.
But: what about R: 1. c6-c5 c2-c3 2. Sc3-b1 Th1-a1. Doesn't this completely cook it anyway?? How about k7/4n3/6P1/PPpPPP2/qQKbrrp1/ppRppp2/b1P5/1n6? h#2 (with Art 15 so it's really h#1.5)
Do you agree? (2021-10-23)
Mario Richter: In the diagram, both for WTM and BTM the retraction sequence c2-c3 Sc6-e7 De1-b4 Sb4-c6+ works and furthermore Andrew's R: 1. c6-c5 c2-c3 2. Sc3-b1 Th1-a1 shows, that Henrik's guess of the omitted wTa1 might be wrong. Instead, I think that Andrew's modification might be in fact the original Dawson diagram. (2021-10-23)
A.Buchanan: Yes that makes sense. I can well believe that there was a lot of constructions in flight when TRD passed away. It's not surprising that something appeared a few years later. Can we get access to FCR from that year to validate? (2021-10-23)
A.Buchanan: Brian Stephenson kindly checked the original magazine. He wrote:
"Eventually got round to looking out this TRD problem. It was published in the issue you quote as problem 10381. The diagram in PDB is wrong. There should be a bPc2. The solution was published in FCR April 1956 as: 1.Pb5xPc5ep Qxa5 2.Qb7#. Last moves must have been 1.Pc7-c5 Pg5-g6 2.Sc6-e7 Qe7-b4 Sb4-c6 ch etc. No flaws were noted, but I have looked later than that issue. Hope this helps." (2021-11-13)
A.Buchanan: The appearance of the 16th Black unit thanks to the offices of Brian Stephenson simplifies the retro logic substantially, and the solution seems sound. Amazing how much disruption a simple typo can cause, but at least this one I believe is laid to rest (2021-11-13)

wie lautet die Retroanalyse? Warum sollten die Rochaden nicht möglich sein?
Henrik Juel: White pawns captured all 8 missing black men, incl. [Pa7,e7,h7]
For both white castlings to be possible, 4 black pawn captures are needed (axb, dxc, e2xd1/f1, and hxg)
but only 3 white men are missing, so the the white castlings are mutually exclusive (2021-11-22)
Henrik Juel: HC+ Popeye 4.61, if '2 solutions' is added to the stipulation
The 2 solutions are 1.Th7... and the one with the permissible castling (2021-11-22)

Die kürzestmögliche OR erfordert 23 schwarze Züge (C+), die Zugfolge ist nicht eindeutig.
In "32 personaggi e 1 autore" (p.533) fälschlich ohne wBb7 abgedruckt (aber mit korrekter Steinkontrolle 10+11). Die Korrektur ist nachzulesen in "La genesi delle posizioni" (p.217).
Henrik Juel: The task of changing who has the move can be accomplished in 15 black moves:
1.La7 Kb2 .. 6.Lb8 Kb7 7.La7 Kc7 8.Lb8+ Kc8 9.La7 Kb7 .. 15.La7 Ka1 16.Lb8,
or, if it is Black to move:
1... Kb2 2.La7 Ka3 .. 6.La7 Kb7 7.Lb8 Kc8 8.La7 Kc7 9.Lb8+ Kb7 .. 15.Lb8 Ka1 (2012-07-26)
Mario Richter: Since the wL can lose a tempo on b6-d8, the OR can be done even faster:
WTM: 1.La7 Sb7 2.Lb6 Kb2 3.Ld8 Ka1 4.Lc7 Sd8 5.Lb8
BTM: 1. ... Sb7 2.La7 Sd8 3.Lb6 Sb7 4.Ld8 Kb2 5.Lc7 Sd8 6.Lb8 Ka1
My guess: diagram error. (2012-07-26)
TBr: Indeed, Mario, a diagram error just in "32 personaggi e 1 autore" (p.533), where the diagram is given as here -- but with piece count 10+11!
Correction in "La genesi delle posizioni" (p.217): Add white Pawn b7. (2012-07-26)
Henrik Juel: With a white pawn added on b7, the play by black king is a1-b2-a3-a4-b5 followed by a round trip, the orientation of which depends on who has the move, like in P0005205 (2012-07-26)
A.Buchanan: For an article I am writing, does anyone have any pithy quotes by Ceriani about ortho-reconstruction, preferably in Italian, please? (2023-08-10)

Zvi Mendlowitz: This is a *great* problem!
Solution: Sd8-e6 (2004-12-07)
hans: R: -1. … Sd8-e6 -2. b6xLa7 Lb8-a7 -3. c5xSb6 Lf4-b8 -4. d4xTc5 Lh6-f4 -5. e3xTd4 Lf8-h6 -6. f2xDe3 g7xLf6 -7. Lg5-f6 Df3-e3 -8. Lc1-g5 Kc4-b3 -9. d2-d3+ etc.
Other captures: black h7xg6xf5xe4xd3xc2 Captured pieces are random.
It’s *great* that d8 is only square for S. (2013-01-30)
Henrik Juel: Another try, d7-d5 as last move, fails, not because the access for [Lc8] is cut off ([Lc8] could have been captured on c8), but because following -2.b6xLa7 [Ta8] cannot get home when g7xLf6 is retracted (2013-01-30)
Yoav Ben-Zvi: The cage locking element in the try noted above is made thematic through 5-fold Echo
Tries:
-1.Pd7-d5 -- NW cage prevents escape of BRa8 to be captured by WPf2
-1.BPg7xBf6 -- Cage prevents escape of BBf8 to be captured by WPf2
-1.Nc5(d4)-e6 -- Blocks path of White Pa7 to f2
-1… Pb6xBa7 -2.Ne6-c5(d4) Pc5xb6 -3.Bb8-a7 Pd4xc5 -4.Bf4-b8 Pe3xd4 -5.Bh6-f4 Pf2xe3 -6.Bf8-h6
-6…Pd2-d3 -- Cage prevents escape of WBc1 to be captured by BPg7
-6…Pa3-a4 -- SW cage prevents escape of WRa1 to be captured by BPh7
-6…Ph3-h4 -- SE cage prevents escape of WRh1 to be captured by BPh7
Two other Retros by Yehuda Veisberg were printed in "The Israel Problemist" (1964) one from FCR and the other from "The Palestine Post" (2013-01-31)
Mario Richter: For -1.Pd7-d5 and …Pa3-a4 more precisely the reason for the illegality consists in a conflict between the uncapture of a bishop and a rook. (2013-02-01)
A.Buchanan: A satisfyingly unified little problem with precise tempo. WQR cannot be captured on c2 inside the White cage, since c2 is surrounded by dark-squared White units prior to Pd2-d3. BQR cannot be captured on a7 inside the Black cage, since BKB is too slow to reach any square for capture apart from a7 right at the end of the line. (2013-02-03)
Henrik Juel: It is nice to review this fine retro (although it would be even better, if it had not been necessary to stipulate that it is White to move)
The last three single moves are determined (2018-01-12)
Alfred Pfeiffer: Deleted "White to move", because this was not a part of the stipulation in the original. (2018-01-12)
Henrik Juel: Please undelete this again, Alfred
Without the knowledge that Black must start the retroplay, we can start with -1.b6xLa7 Lb8 etc., and the surprising intended solution -1... Sd8! vanishes (2018-01-12)
Alfred Pfeiffer: OK, but "White to move" is usually the standard in problems (except help problems). (2018-01-12)
Henrik Juel: Yes, Alfred; but there is no forward stipulation (like #2) in this retro problem (2018-01-12)
Yoav Ben-Zvi: Apparently Dawson considered the stipulation "What was Black's last move" as indicating that Black was the last to move and therefore equivalent to "White to move. Last move". An alternative could be "Last move. a)Black to move b)White to move". (2018-01-14)
Mario Richter: For 'Last Movers' we also have the "Type A", "Type B" etc. categories ... (2018-01-16)

Henrik Juel: "Play a game with S's" does not fit well with 4... Dh4 5.g4 (2020-12-23)
A.Buchanan: I think it's simply a constraint whereby knights can't attack one another. There is no requirement to actually move any horsies. I will remove an errant comma from the stip. I am not a fan of synthetics, have to say (2020-12-23)
