Woher kamen die sTTa8 und h8?
Henrik Juel: The rooks have switched place. Following -1... Rb8:S -2.Sb6, bRb8 retracts further to g8, bBd8 retracts to f8 and bPe6 to e7, to allow wK to exit via e6; retract bRh8 to h6 and h7xRg6 etc. wPg4 cannot retract until orig. wRh1 is home. This is the only Volet retro with a K in check, composed in Tom's youth, before he saw the light! (2003-11-25)
Thomas Volet: The exception in this case to the otherwise observed constraint of not having a check in the diagram or stipulation as to who is on the move relates to a collegial colloquy at the time with with the composer J.G. Mauldon, who was active in this task. (2022-03-24)
A.Buchanan: Terrific composition! Often in a Type C composition, one might retract the check to give Type B. But the thematic Ta8 here could not exist without a check in diagram. There are different areas of design space are accessible depending upon level of self-imposed constraints. Some retro composers like Baibakov systematically explore Types B&C as well as Type A. I don't see this as any kind of defect.
I particularly like that the lock on h-file only allows one sT to squeeze itself out. (2022-03-24)

Henrik Juel: If Black may castle, his latest move must have been e3xf2, so last move was e2-e4. (Orig. wPg2 promoted on g8, so g7xh6 happened early). 1.dxe3 e.p. 2.fxg1=B 3.0-0 Tg4# (2003-03-21)
James Malcom: Is this the only know one-sided Valladao in a regular series-mover helpmate? Also, can wPh2 be shifted to h4, and the White king moved as well to h2, so that the solution must have 2. fxg1=S? (2020-12-08)
James Malcom: Well, the only known one that is in minimum form, i.e. 3 moves, I mean. (2020-12-08)
A.Buchanan: This is nice. I don't know of any other AP ser-h#3 with Valladao, but there could be. Just been cleansing PDB data today. Yes I think wKh3 and wBh2 can be transposed, and then promote to S instead of L. (2020-12-08)
A.Buchanan: The legality of intermediate positions in seriesmovers is of course irrelevant. However, each proof game that leads to the diagram position with BTM can be appended with a black move and then a "flip" that changes the player to move. We can repeat this process, and then the fact that Black retains castling rights implies that they had castling rights in the diagram position. I think this is the right formal way to handle AP with seriesmovers. (2022-03-21)

H.Juel: If Black may castle, last move was not made by Ke8 or Ta8, but by Pd5, so it was d7-d5, and hence White may capture en passant. 1... exd6ep 2.0-0-0 dxe7 3.Tf8 exf8=D,T# where the castling (belatedly) justifies the e.p. capture.

VL: The first AP-problem! Thematic illegal try:
1. ... exd6ep 2.Kd8? dxe7+ 3.Kc8 e8=T(D)#?? (2007-02-11)
Mario Richter: 46 years between this Problem and P1366663 - perhaps this was not Keeble's first AP-Problem?! (2019-08-29)
Ladislav Packa: Of course I know the idea a posteriori. But let my heresy be forgiven - I do not consider it logical. In this particular example, I consider e.p. for proof that black can castling - not vice versa. (2019-08-29)
A.Buchanan: Hi Ladislav. If ep is ok, then Black just moved a pawn with double hop. That doesn't stop Black having e.g. moved bK right at the beginning of the game. So you can't prove that Black definitely can castle this way. What am I missing here? (2019-08-29)
Ladislav Packa: Your statement is perfectly fine. However, the AP condition is usually interpreted as castling is evidence of e.p. However, the second party does not have to do castling - the possibility has already been demonstrated by the existence of e.p. (2019-08-29)
A.Buchanan: Hi again Ladislav. Please try again, I am obviously being very stupid. I don't understand how 1. exd6ep is any more indicative that Black can castle than 1. K~. (2019-08-30)
Ladislav Packa: Hi, Andre!
e.p. is just a result of the d7-d5 move. Black can castle only if it was the last move of black (even without wPe5). Therefore, it does not have the logic of joining the e.p. with castling. For example, ask yourself if black is allowed to castle in the position without wPe5. (2019-08-30)
A.Buchanan: @Ladislav: ep is not "proof that black can castle", rather it is a *necessary* condition for Black to be able to castle. The logical implication is the other way round. We can castle because of the optimistic convention, and because sPd might just have moved. Without wPe, there is no solution, but whatever White plays, Black can castle (2020-12-11)
Hans-Jürgen Manthey: was heißt hier Thematisch Illegal ??
Mir völlig wurscht ob ep möglich oder nicht, nach dem weißen Zug ist natürlich Kd8 möglich !!
also ist auch 1. ... exd6ep 2. Kd8 dxe7+ 3. Kc8 e8DT# eine Lösung, sonst müßte auf die erzwungende Rochade in der Aufgabenstellung hingewiesen werden ! (2020-12-11)

In a&b have the same two forward solutions, one with White Castling the other with Black. So it must be retro concerns that eliminate one solution in each case. bRg8 is original in any case, as Black has 7 pawns, and bBa5 is promoted.
a) bhP must promote on g1 This allows for 4 captures of bPb3, but there is no chance for cross-capturing of b b&c pawns. White g and h pawn cannot reach Black cage to promote inside. So Black castling cannot be preserved. But bB once promoted can easily escape, so White capturing is unimpeded.
b) bhP can make 1 capture to promote, but now cannot escape without kicking wK, so White can't capture. Cross-capturing is still not possible, but wbP can promote on c8 without disrupting bK.
This is not PRA but twinned RS.
VL: Nothing to do with Retro Strategy (nor with PRA). One definite castling is legal in every case. (2021-02-09)

Max J. Meyer in 'Brighton and Hove Society', 1904: "It will be seen that the ideas of these two problems [dieses und P1143870] are the same. The addition of the White B. enables Mr. Mackenzie to get a much better key for this position, a point in which Steinweg's problem does not excel; but, of course, the use of an extra piece renders the miniature less remarkable from the point of view of smallness in size."

A.Buchanan: Here the threat play (1) is sound & (2) can never occur as Black has no neutral move. But if threat play is *unsound* yet can never occur, can it be safely ignored or will some directmate purists regard that as a defect? (2022-04-02)
Henrik Juel: I think not, Andrew
When I test problems, I ignore plays that do not occur (2022-04-02)

(a) sLa7 is promoted. If White castling rights remain, then bPf captured fxgxh2xg1=L, which with dxc6 makes 4 captures. White has lost Bd, Be, Bf/h & Lc. However, wBe can't have captured or promoted (h/fxg & Lf at home are the only Black casualties), so can't have contributed to Black captures. Therefore impossible, and wK did lose castling rights before. Now trivial for sBf to have promoted.
(b) sLa7 can be original, so castling is still ok. Even if sLa7 is promoted, wBe can have promoted, and again White can still castle.
The forward play is more varied than is usual in these kinds of problems.
Kees: a) 1.Td1! [2.Dc4‡]


b) 1.0-0-0! [2.Dc4‡]

La7 is promoted.
In a) fxg/e=L King must move (e2 cannot promote) so no 0-0-0.
In b) fxgxhxg=L and 1. 0-0-0 for 1. Td1? Te8! (2022-02-02)

7 Black pawn captures: QRRBSSPP
2 White pawn captures: QSP
If White just moved, then d2xe3, and wBc1 retro blocked. This means all captures accounted for, but how did h pawns pass?
So, WTM.
There are numerous BWBW and BWB mates, but there is only one WBW mate.
A.Buchanan: Odd. As h#2 there are many solutions, not just the nice slow-rolling wPb one. And these are all eliminated for both retropat reasons and because they are longer than the actual one. Why is the stipulation not just h#2? (2021-10-20)

Cook: e.p. not justified as R: 0.e3xd4 possible
VL: Unjustified ep-capture because of –e3xd4. For correction it suffices e.g. to add bSe3.
This is possibly a unique 2-move helpmate with ep-key and 2 solutions of the type 1.2.1.1 (at least so currently in the PDB).
Publi?ation details. H551 in the Helpmate section of the July issue, with no preview. Here is the text of the solution published in the Nov.-77 issue: “…White may have just played P(e3)xd4. Very few solvers have spotted this. Full marks for claim of no solution with correct reasoning but, in fairness, one mark for composer's intention. White cannot have just played K(a5)a6 in reply to Pxb6+ as too many captures by Black are required.” (2023-12-01)
A.Buchanan: Yes Valery you are right this must be cooked. However, I'm not a fan of +bSe3 because it spoils one of the model mates. Separately, I mildly prefer bPf7 to bPe6. (2023-12-03)
VL: I do prefer bPf7, as well. I don't see any way to save at least one of the properties Kindergarten Problem and Model mate (2) after fixing (what for these keywords have been added just now?). Besides, Andrew, please, refine the specification ((full) number and publication month 07-08). (2023-12-03)
A.Buchanan: Ok have added the publication details. The keywords are useful to indicate the aim, even though the problem is cooked. I guess there is a way to keep the model mates but it’s very clunky and probably +bSe3 is better (2023-12-03)

Mit dieser Aufgabe hat BoL vermutlich erstmals den Begriff der ZeroPosition eingeführt. Hier zeigt die Verwendung der ZeroPosition auch thematische Geschlossenheit insofern, als bei Versetzung des wS auch UW in S erfolgt, bei wT auch UW in T etc. Es besteht also ein Zusammenhang versetzte Figur zu Umwandlung (eb).

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?"

a) unlösbar b) mehrere Lösungen (2020-12-08)
SCHRECKE: Der wBc2 muss offenbar auf b2 stehen!
Dann gibt es die Lösungen:
a) 1.Tb6 2.Se6 3.c5 4.c4 5.Sc7 L:b6#
b) 1.Df4 2.Sd6 3.e4 4.e3 5.Sf5 D:f4# (2020-12-08)
Mario Richter: Im Originaldiagramm wBb2 statt wBc2 - Stellung entsprechend korrigiert. (2020-12-09)

Alfred Pfeiffer: Was ist "Iceberg"? Ist das eine Art Augsburger Schach? (2010-09-29)
Alfred Pfeiffer: "Iceberg" ist Peter Fayers' Version des Augsburger Schachs, bei folgenden drei Unterschiede gelten (Quelle: "http://www.bcvs.ukf.net/augsb.htm"):
E1: Pieces may combine, but not kings, and NOT PAWNS either (not even when moving to promote).
E2: The game-array queen is not separable, and Qs are distinct from (R+B)s.
E3: A pawn may promote to any combination seen in the diagram, or generated during play. (2010-10-11)
A.Buchanan: Link is now at https://www.mayhematics.com/s/augsb.htm. Piece images to make up the diagrams have been lost, but you can get a clue what the diagrams were by clicking in the html. (2019-02-04)

Original ohne wBb2, mit wKb1 und sLa3 veröffentlicht, dann aber NL 1. bxc3ep, weil danach W als letzten Zug Kc2-b1 hatte.
In der korrigierten Stellung (03/1988, S.400) hat W nach bxc3ep nie einen letzten Zug, so daß dieser ep-Schlag erst am Ende der Lösung gespielt werden darf.

Außerdem bietet der Autor noch einen Zwilling an: Ks a5/a4, zusätzlich Monchromes Schach, shc#6

The interest here is in the try 5. h1=T? 6. Th8, when, in a game to that position, the sK or sT must have moved to let out Ta8 to be captured (0-0?). The solution is a surprise, involving castling round the cylinder instead.

play all play one stop play next play all
Fuddled Men is a recent Fairy form invented by John Beasley, in which all men (including Kings) are unable to make 2 moves in succession. This is a Fairy form with great potential both on its own, and combined with other Fairy rules.
No. 2184 HN
Walter Lindenthal: Why not (b) as follows:
(b) 1. wKg2-h2 by White (provided bBg1 is 'fuddled' at that moment).
The wBf1 was captured possibly by a bS before (or the wK gave way for its capture), it need not have been ... Bfl-g2 h3xBg2 ...
So, the last moves: ... bPh3-h2 wKf1-g2 ... bPx?g1=B wKg2-h2
Yes, this will result in an 'automatic' Mate after black's next move, but it seems fully legal under Fuddled Men rules! (2021-01-17)
A.Buchanan: @Walter if "bPh3-h2 wKf1-g2 ... bPx?g1=B wKg2-h2" tHen what moves can be in the "..."? There are no spare black pieces to be uncaptured, as S&R are captured by wPg & wPh. (2021-01-17)

Across these two cases, both castling rights are demonstrated.
play all play one stop play next play all
If we can assume that none of the White pieces in the first row has yet moved, then we must assign the move to Black. When this was published in The Problemist, opinions were divided. "White, to prove that the move is Black's, begin by claiming the right to castling on each side: and as they cannot in fact make both castles at once to establish this claim, it is sufficient to make one in each variation." "The solution consists of all the variations, and it is sufficient to have 0-0 in just one variation, since the small castling is enough to show that the move is Black's". "Since White claims the right to kingside castling, Black is forced to offer the opportunity" "No solution on 0. ... Rh1"

Si nous pouvons assumer qu'aucune des pièces blanches de la première rangée n'a encore joué, alors il faut attribuer le trait aux Noirs. D'où: 0. ... Rf3: 1,O-O+1 Re4 ou e3 2.Tae1# 0. ... Rhl: 1.Dd2I Rgl 2.O-O-O# Quand cela fut publié dans The Problemist, les avis furent partagés. "Les B., pour prouver que le trait est aux N., commencent par revendiquer le droit au roque de chaque côté: et comme ils ne peuvent de fait effectuer les deux roques à la fois pour établir cette revendication, il suffit d'en éxécuter un dans chaque variante". "La solution se compose de toutes les variantes, et il suffit d'avoir O-O dans juste une variante, puisque le petit roque suffit à montrer que le trait est aux Noirs''. "Comme les Blancs revendiquent le droit au petit roque, les Noirs sont forcés d'en offrir l'opportunité""Pas de solution sur 0. ... Rh1 :"

A.Buchanan: My feeling is this doesn’t work, sadly. In an adversarial stipulation, Black can simply avoid ever playing the line that allows White to “prove” that Black had the move. In a helpmate on the other hand I suppose if PRA-AP is expressed properly, there should be no problem playing multiple parts. (2022-02-15)
