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: something is wrong here: the claimed mates are not even checks
also, the stipulation should probably be something like
Black and White retract, then #1 (2021-04-30)
A.Buchanan: Yes the problem was the word "dann" which indicates help retractor. The retro is just justification for the forward moves, showing that the relevant fairy piece existed earlier in the game so can be promoted to. What's the name of that principle? (2021-05-01)
Henrik Juel: Thanks for the clarification, Andrew
I think that this principle should remain unnamed and just stay in the joke realm (2021-05-01)
A.Buchanan: Sorry not to be clear: I am talking about the standard fairy principle that if you want to promote to a Princess, there should be one on the problem diagram. Not talking about the joke extension which riffs off this. I thought this was called "Bartel Theme", but it turns out that is something different. (2021-05-01)
Henrik Juel: I see; that principle probably was established soon after the invention of grasshoppers and nightriders
I do not think it has a name, but it is so well established that it should be in the Codex (2021-05-01)

Mario Richter: Luboš Kekely (Slovakia) correctly points out that 1. ... Sf5! 2. 0-0-0 Sd6# is only a try and not a solution (last black move must have been by King or Rook, so the queenside castling is illegal).
I have changed the solution accordingly. (2023-03-10)

1. ... bxc7! 2. b6 c8=S 3. Lc7 Sxa7#
*) 1. Lc8 bxa7 2. Kd7 axb8=S#
Numerous retro tries h#3 but none distinct, however unique h#2 which serves as setplay under Art. 15.
A.Buchanan: In some cases, as here, the unique retro try is short: just h#2. It's clearly intentional (the 3 Bl units on e-file serve just this line). (2021-10-20)
A.Buchanan: For h# problems, Art. 15 is just a motivation for set play. They come down to the same thing, pruning the first single move. So if we talk about set play for an Art. 15 problem, maybe it means *after* the player has been flipped for retro reasons. And set play doesn't care whether the position is legal or not! (Otherwise it would be called "*consequent* set play", maybe!)
So here we start with a h#3*, which for retro reasons, becomes a h#2.5*. This yields a mate in 2.5 and a mate in 2.0, and comically we never get to worry that the latter is in an illegal position. If there was a clean mate in 3.0, that could be denoted h#3v, to indicate the try.
Does that work as a notation? How about directmates? (2021-10-20)
Henrik Juel: In problems with stipulations like #2 or #3, the convention is that the number (2 or 3) is the number of white moves, so there the retro joke is clear
For helpmates there is no such convention, but your notation seems OK (2021-10-20)

Adrian Storisteanu: Above the "diagrammes" diagram there is: R. SHANKAR, Inde. In the volume index, under RETROS: this is the only problem of a composer named (just) "SHANKAR" (one original), while "RAVI SHANKAR" is a different author (with two originals). (2024-02-20)
A.Buchanan: I suggest that S.N.Ravishankar check the reaponse to the query (A='Shankar' or a='Ravishankar') AND NOT A='Shankar Ram, Narajan' as there are many other similar retros which are attributed to Ravishankar. If he can state here which ones are not his, I will happily modify the data. (2024-02-21)

Ladislav Packa: Set Play: *1...cxQb6 Qc6-b6+, then 1.Kc3= (2021-05-23)
A.Buchanan: That's a cute line Ladislav: is this how set play is defined for a help retractor? I find the stipulation as it appears absurdly opaque. I would have ignored the problem in a magazine but maybe the opacity was added in entry to PDB? (2021-05-23)
Ladislav Packa: Andrew, without unnecessary words: compare with P0006003 (2021-05-23)
A.Buchanan: Hi, Ladislav: neither mentions set play. Both have main play -w-s:+s+w. Dawson's setplay is -s:+s+w, which I guess I would have expected. But your nice play here is -s-w:+w (2021-05-23)
Ladislav Packa: "Normal" h=1 means 1.1B 1W=. Set play in "normal" h=1 means *1...1W=. If you consider the "normal" part h=1 as the basis, then I do not see any logical problem when considering the retro part. (2021-05-24)
A.Buchanan: Hi Ladislav. Normal is -w-s:+s+w as here and Dawson. Dawson's normal set play is -s:+s+w. What you've done is something different -s-w:+w. That's not normal set play, it must have a different name. What do you want to call it? Pretty much anything you like, but the one thing it must *not* be called, out of all of the pronounceable strings of characters, is just "set play" without qualification, because that is guaranteed to confuse :-) So what name do you like? (2021-05-24)
Ladislav Packa: The logic of time sequence says that the first is a "normal" game and retro (again chronologically) follows it. So, according to this logic, set play should primarily apply to "normal" play. But I don't want to force anything on anyone. In any case, it would probably be wise to indicate in the stipulation which part of the problem the set play applies to. (2021-05-24)
A.Buchanan: Or maybe for a help retractor, what you call "normal" should be called "set retroplay", while your innovation is the true "set play" :-) (2021-05-24)
Ladislav Packa: It could be quite simple: h=1* befor 1, or h=1 befor 1* (2021-05-24)
A.Buchanan: I like that symbolic syntax Ladislav and we need to be able to describe it in words too. I think set play and set retroplay is logical. As long as people figure out that it's always Black gets stalemated (i.e. no whiff of duplex), and that there's no "flipping" of who has the move except in the initial diagram, then we're good. "vor" doesn't quite translate into English. I think the retraction should be specified before the action, e.g: "Retract 1, then h=1" like the PDB solution syntax. And then God help us the 1.2/1.1 which I think now is reasonable (2021-05-24)

A.Buchanan: The final position in Kees' solution has wTf6 which must be promoted. This could have been wBb, which captured e.g. bBa5, bBb6 e.p., bLa7, bSb8.
wTf7 is also promoted, and might be sBh having capturing wBg5, wBh6 e.p., wLg2, wTh1. sBfxLg6 completes the picture. I don't see any difficult captures e.g. of S remaining, so the position looks to be legal. (2022-02-16)

Composing exercise 50 was announced in Thema Danicum no. 72, where the editor Holger Helledie asked for help mate problems with 1 white and 1 black promotion, as long as possible
Theodor Steudel pointed out that problems as short as possible were also relevant, and the submitted problems along with many old ones were shown in TD no. 73, where HH expanded the criteria to
1. As few men as possible (4 was achieved in 1927: Kh8 Pf7 - Ka1 Pb3, h#2)
2. Shortest or longest possible (from h#1.5 to h#10, the latter from 1956: Kc1 Pc2 - Kh7 Pc3e4)

Yuri Bilokin: Correction: wRh4-h5 8/8/5k2/7R/6n1/8/5B2/5K2 (3+2) (2021-04-16)
A.Buchanan: I don't know what to do here. Clearly we can't disrupt the rook square, so maybe +sBf3 is best as Yuri proposes (2021-04-16)
Yuri Bilokin: It is necessary to decide what is better to break the rook square or the Ideal mate. (2021-04-16)
A.Buchanan: Ideal mates are cheap, but Th4-h3-g3xg4-h4# is a prize. (2021-04-17)
SCHRECKE: why not: +bPh3? (2021-04-17)
A.Buchanan: @SCHRECKE because the rook's movement in a square should not be motivated by capturing, and +sBh3 also blocks wT unnecessarily from h1 & h2. This problem does not appear in WinChloe, at least not in Canadian Chess Chat under this author (who has 891 total compositions - not gone through them all). Maybe he never fixed it. One clean idea is to replace wKf1 with sBg2. This is still an ideal mate. Then put +wKa1 if you must :-) (2021-04-17)
A.Buchanan: +sBg2 & wKa1 is sound, but maybe best to rotate the board as sB threatening to promote is perhaps unfairly distracting to solvers (2021-04-18)

Adrian Storisteanu: Or, finally, a variation which uses just a bP (not bB) as Andrew suggested, and still makes use of the wK (as does Yuri's):

Adrian Storisteanu: Or, more centred:
Bb7 Re4 Kc2 / Kg6 Pc5 Se5 (3+3)
1...Rd4 2.Kf5 Rd5 3.Ke4 Rxe5+ 4.Kd4 Re4# (2021-04-18)
Adrian Storisteanu: (In the latest, a bPe5 -- instead of bSe5 -- is just as good...) (2021-04-19)
A.Buchanan: Busy - will check these later. But Adrian I didn’t suggest bB but sB i.e. (German) black pawn not bishop (2021-04-19)
Adrian Storisteanu: I understood you fine (but I might have misplaced the text in parentheses). (2021-04-19)
A.Buchanan: With your latest Bb7 Re4 Kc2 / Kg6 Pc5e5, once might as well remove the two black pawns and replace with wPd6 (then rotating the board by 180 degrees). But surely this is not original, and indeed P0510694 by Ugren achieves full h#4. But Yuri has already corrected P0503631 by Krikehli to achieve the same thing! Time to give up - nothing new here.

Thema des TT ('The Problemist' 09/1992, S. 88): "... composers are required to combine 2 (or more) problems to make a distinct third."
(Im 'Problemist' haben die Teilaufgaben a),b),c) und d) die Labels: D,A,B und C.
PR Barry Barnes vermutet in seinem Kommentar zu diesem Problem, daß ein Computer bei der Erstellung geholfen haben könnte: "Essentially disparate parts (A),(B) and (C) come together as something quite new in (D). But note a minimal record: 5 pieces, cyclic absence of 2 of the pieces, 4 different series-demands, and only ideal mates! Was Holmes right in thinking that a later model of Prof Babbage's "engine" (Cambridge,1834) determined the solving conditions and lengths?"

If this were a retro problem, there would be no solutions
But here you can also view it as a sequence of black moves, ending with DxPf5, say (2023-01-25)

Henrik Juel: These solution corrections should help the animation:
3... g2-g1=D, 6... f2-f1=S, 24... Db1-b2
Hans-Jürgen's numbering is a single move off from retraction 28.
(1.c2xDd3 is white, 28.a5xDb4 is black)
The stipulation seems to ask for the minimal number of black knight moves
(usually SS means knights, but here it may mean 'schwarze Springer') (2021-07-10)
Mario Richter: Henrik, if the question were about black Knight moves only, wSh3 would be able to make tempo moves, allowing e.g. to start with c2xTd3 instead of c2xDd3.
I do not have the official solution, but it obviously is: 4 Knight moves - wSb1-c3-d1,wSg1-h3 and bSb8-d7. bSg8 didn't move at all and was captured by a White officer. (2021-07-11)
Henrik Juel: Thanks for your new solution, Mario, and for your enlightenments
I was misled by the originally stated solution and by Hans-Jürgen's retro game
The german convention that D means Dame=queen and DD means Damen=queens etc. may not be generally understood, so for clarification I suggest that the stipulation is spelled out, something like
Welches war die minimale Anzahl von Springerzüge?
I totally agree with your comment on the strong condition implied by the stipulation (2021-07-11)

A.Buchanan: This is really wonderful. and I wonder if its thematic originality and apparent simplicity maybe denied it a higher prize. Note how three Black units, which all have other day jobs, block wK from executing the White waiting move. On the other hand bRg1 can’t do the black waiting move, again for check reasons (2021-06-24)
A.Buchanan: And why have the bRg1 anyway? Well, it prevents a large number of cooks in a, because otherwise wRd1 can't be captured as it will respawn on h1. On the other hand it prevents premature check in b, and the respawn on a1 *is* an issue. Harmonious asymmetry, in both cases requiring that b1 & d1 be cleared, and that all the pieces have multiple roles. (2021-06-24)
A.Buchanan: Where a theme appears both for white and black also can be more challenging than where the theme is echoed by the same player in the twin. The position needs to be fundamentally reperceived in such a twin, and to achieve great economy is even more laudable, imho. (2021-06-25)

Der letzte Satz des obigen Kommentares gehört sicher nicht zu dieser Aufgabe, sondern zum gesamten ortho-Urdruckangebot.
Wenn der wSg8 - wie oben vorgeschlagen - nach d5 versetzt wird, steht der sK im Schach! Mit wSg8->d7 löst nur 1. Se5!

(A. Beine). Für eine Ultraschachzwang-Aufgabe gibt es reichen Inhalt: wB-Minimal, insgesamt 7 D-Umwandlungen, wobei die beiden wD-Umwandlungen durch zwei verschiedene Schlagfälle realisiert werden. Dazu in a) doppeltes Kreuzschach und in b) doppelter Batterieabzug des sK.
Ganz unüblich schwierig. Vom Blatt spielen läßt sich das keineswegs (WW).

(H. Brozus). 1.Dd5! Kh1 2.Kd2 Lg1 3.Dh5+ Lh2 4.Df3 Kg1 5.Dd1+ Kf2 6.De2+ Kg1 7.De1#. WW: Sehr verführungsreiche und überzeugende Miniatur! KHS: Hübscher Platzwechsel zwischen wK/wD. Ein Löser bemängelte, dass es lange sieben Züge dauert, bis der Platzwechsel hergestellt ist und nicht schneller geht. Ich finde gerade das als Pfiff des Problems, dass es eben mit einem dreizügigen Dreieckmarsch nicht getan ist!

Langer Königsmarsch und wB-Minimal. Auf hohe Zügezahl ausgelegt. (Autor).
Eine Erweiterung der 2854(PK 12/1991). Für meinen Geschmack hat es sich kaum gelohnt(KW). Die Forderung sieht auf den ersten Blick verblüffend-absurd aus(HG).
