For 4) probably a name with those six letters A-C-D-I-L-U (2012-2-22)
Henrik Juel: The answer to part 4) is, I think, Michel Caillaud, as his last name only uses the six letters in the problem (2012-2-22)
Alain Brobecker: Dedication was given with pieces symbols. This eases things a lot! (2012-2-22)
Brassaud: Wem ist das problem gewidmet ? My ‘april fool ‘solution.
Probably a name with those six letters : KPQNNPBR … for King, Pawn, Queen etc … Which suggests: ACDILU and so Michel CAILLAUD. But this is a code, and there is no reason to say that it is not the coding of other letters.Chess problem Data Base Server contains several ' retro ' problem authors whose names contain 6 different letters.
When classifying by number of published problems, we can find : M. Caillaud, L. Ceriani, T. Dawson, W. Dittmann, T. Steudel, A. Kisljak, A. Buchanan, G. Donati, T. Kardos, N. Dupont, W. Frangen, D. Baibikow, E. Bartel, P. Kniest, M. Richter etc. .. (and even, but very far behind : F. Brassaud)- So everyone has to make a choice. (2017-12-9)
Henrik Juel: Curious that so many well-known composers happen to have exactly six different letters in their last names (2017-12-9)
Olaf Jenkner: Footballers have eleven different letters in their last names. (2017-12-9)

Färbe die Steine! Welches war der letzte Zug?
Henrik Juel: White: Kg8, Qh8, Bf8,g3, Pa2,a6,b3,c2,d2,f2,h7 (11+11). -1.B=g7:S. (2003-11-20)
Brassaud: The solution proposed by Henrik does not seem appropriate. White: Kg8, Qh8, Bf8,g3, Pa2,a6,b3,c2,d2,f2,h7. So : Queen g8 and one of the two bishops are promotions, and seven pawns ?
Whatever the color of the pieces : on the diagram there are eleven pawns, at least three queens promotion and two bishops promotion (four bishops on black fields). Total sixteen pawns (or equivalents after promotion). So there is the necessary presence of the two originals queens.
The queen in g8 is a white promotion (last move g7xh8 = D +)
If the king f6 is black: the queens d6 d8 f4 and h6 are black. The white queen from e1 is absent.
If the king f6 is white: the queens d6 d8 f4 and h6 are white. This is the black queen from e8 who is absent.
Could this be a diagram error (2017-12-13)
Brassaud: erratum : queen in h8 (2017-12-13)
Mario Richter: Henrik's solution is absolutely legal - wQh8 is the original wQueen and last move was: g7xSf8=L+. (2017-12-13)
Brassaud: Sorry I had not understood the last move B=g7:S, it's easier with g7xSf8=L+. Thank you Mario. (2017-12-13)
Henrik Juel: In my uninformed youth I wrote in English, also for the men (S=knight), with very abbreviated notation in retroplay
-1.B=g7:S reads 'bishop unpromotes (=) to g7, uncapturing (:) a knight' (this is sufficient, as there is no bishop on h8)
Nobody else thought this was a good idea, and now I use KDTLSP for the men and full notation for uncaptures, e.g., -1.g7xSf8=L
Sorry about the confusion, Francois (2017-12-13)
Henrik Juel: For this enjoyable problem I should also have written the pawn play, like
White: e2xd3x..xa6, g7xSf8=L
Black: c3xb2, dxe, fxe, e1=D three times, gxh, hxg, g1=L (2017-12-13)

Renny Bosch: Aside from that sensational 1 5/8 full circle Knight tour, this composition has some additional challenges. One never really knows one has seen all of a composition's beauty until one has actually produced a proof game. In this case a pawn analysis shows that white Pawns h and g have captured on g and f, exd, dxc, cxb6, bxc3, and a has promoted, black Pawn a has captured on b, and h has promoted. The question is, what happened to the piece that the black h Pawn promoted to? It cannot be one of the pieces still on the board, so it must have been one of the white Pawn capturees, but which one? The only way to unlock the central cluster is to uncapture a white Knight on b5, then walk the bK to b5 and the wQ to d4, after which the wPd6 can uncapture from e5.

Here is a PG (as pretty as I could make it) that shows the whole thing: 1. a4 b5 2. c4 c6 3. c5 Qb6 4. cxb6 c5 5. Ra3 c4 6. Re3 c3 7. Re6 c2 8. e4 Na6 9. e5 Nc5 10. a5 Na4 11. h4 Nc3 12. bxc3 Bb7 13.

Forderungs-Alternative: Einfarben-Schach. Auf dem Brett steht ein unsichtbarer Läufer. Steht er auf einem schwarzen oder einem weißen Feld?
Yoav Ben-Zvi: In the book (page 26) the WB is placed between e3 and e4. It seems simpler to represent this with WB on e4, the stipulation "Monochrome chess. Is the position legal?" and a Twin b) WBe4 to e3. Proof of illegality with WB on e4: There is no piece that could perform the last capture on a dark square since no piece on the board is capable of a dark-squared capture and it could not be a piece that is missing since such a piece would itself have been captured later on a dark square. Smullyan's version uses poetic language including the metaphor of a Bear and a Lion fighting until each has entirely devoured the other. Essentially the argument uses the well-known mathemtical technique of "Infinite descent" leading to "Reductio ad Absurdum": It can be shown that assuming the existence of a "minimal" instance that has some property (such as most recent capture on a dark square) leads to the conclusion that it is not really minimal (there is a more recent capture on a dark square) so the assumption leads to self contradiction and is therefore not true. A formal definition of this method was developed by Fermat (17th Century) but it was used as far back as Euclid's "Elements" (300 B.C.). (2017-12-14)
Henrik Juel: It might be simpler to consider the retroplay:
With Le4 there is no way of producing a dark-squared man by uncapture (2017-12-14)
Brassaud: With Le4 it seems possible to producing a dark-squared man with the retroplay : 1) Lc2-e4, Kd7-e8 2) Ld3xPc2, b3xPc2 3) Ld3-e4, a4xb3 ep 4) b2-b4... But the position remains illegal as shown with the metaphor of the lion and the bear. (2017-12-15)
Henrik Juel: Good point, Francois
But the en passant trick still cannot create a full retroplay back to the initial position with 32 men
I should have written 'officer' instead of 'man' (2017-12-15)
Yoav Ben-Zvi: Henrik's modified claim that "with WBe4 there is no way of producing a dark-squared officer by uncapture" is correct but I do not see a simple way to prove it directly. A "lion and bear" type argument with retroplay could ask "Which of the pieces that move on the dark squares was the first to uncapture?". It should be noted that this piece could not be a pawn that was itself uncaptured e.p. (since the history of such a pawn does not include an uncapture) and that proving that such a piece does not exist proves illegality (since it implies that dark-squared officers such as BQd8 could not be uncaptured). A similar clarification is needed when applying the argument to forward moves.
The Homebase position of the diagram is an IC. It could be presented (optionally adding a WB on f1 and/or a BB on c8) with the stipulation "Is the position legal?" and the Twin b)-WPf2. (2017-12-17)

Henrik Juel: The dark-squared bishops were captured by officers, so the pawn captures were c7xSb6, d7xLc6 by Black and exLf, f2xSg3 by White (when the pawn has been added)
The forward sequence was e2-e3 (or e2-e4) before d7xLc6 before exLf on a light square, so [Pe2] could not reach f4, and the undetermined capture was e4xLf5.
This simple idea was later shown more elegantly in P1012384.

Autor: Aufbau einer wBatterie - orthogonal und diagonal - mit Funktionswechsel der beiden sChamäleons als Vorderstein; Abzug zum Block nach f1 im Mattzug ohne Schlagfall; Mustermatts.
FP schreibt in seinem Buch _Schach mit Partner_ (S. 103). "Während beim Andernachschach schlagende Figuren umgefärbt werden, erleiden dieses Schicksal beim Anti-Andernachschach ziehende Figuren; schlagende behalten ihre Farbe. Das bedeutet, daß im Mattzug geschlagen werden muß!" Auslöser dieses Problems war dieser letzte Satz, denn es stimmt nicht immer, weil es auch ohne Schlagfall im Mattzug geht - wie meine Aufgabe (erstmalig?!) beweist.
Anti-Andernach und Chamäleon, da muß man schon um vier Ecken denken! meint WW;
ähnlich KHS: Mir wird ganz schwarz vor Augen und schwindelig bei diesem Farbwechseln in aufsteigender Figurenfolge; Hut ab vor dem Komponisten, der alles im Griff hat!
EB: Batteriewechsel, durch Anti-Andernach-Schach spezifische dauernde Farbwechsel ziemlich verwirrend (zumindest für mich). Ohne Computer hätte ich mir das gar nicht angeschaut.
Résumé von KHS: Durch die Weihnachtsfeiertage bedingt, hatte ich etwas mehr Zeit zum Lösen und habe mich deshalb an einige, für mich neue, Märchenschacharten herangewagt. Ich hoffe, alles richtig gelöst zu haben!?

Dover, 1945., pg. 133.

"The probability is that (this) is a model mate problem."

"There are three model mates... One occurs in the threat line; a second in a variation where there is a cross-check and where the black rook blocks the black king; and in a third, where the black rook again self blocks." (2012-2-13)
Mario Richter: TO DO: Prüfen Quelle 'The Chess Review' - im gesamten Jahrgang 1937 habe ich dieses Problem nicht gefunden.
In der Turnierausschreibung heißt es: "1937 Miniature Tourney
A 1937 International Composing Tourney is held
for direct mate 3*move and 4-move miniatures (7
pieces or less). Judge: Kenneth S, Howard ... Merit Problems will be published in The American Chess Bulletin."(!) (2017-12-16)

Das 100 Lire-Thema!! (Autor)
Kommentare: Ja, mit Torus...man sollte meinen, dass es da noch viel gefährlicher wird, oder? (HG).
Sehr sparsam realisiert. Hier kam ein schönes Problem dabei heraus und nicht wie bei vielen anderen Versuchen wurde die Bedingung genutzt, um das Ganze nur mal darzustellen (AB).
100 Dollar im (Ring-)Zylinder. Intelligente Begründung für die bei diesem Thema schwierige sS-UW (TS).
100 Dollar auf anderem Brett (MN).
Da haben wir ja das 100 Dollar-Ding (HM).
Noch nicht ganz, siehe die Autoranmerkung. Ich habe mit dem Autor beim letzten mpk-Treff gesprochen. Es ist noch nicht sicher, welche Währung als nächste dran ist. Vielleicht Escudos? \eb
Olli Heimo: Why torus? Isn't horizontal cylinder enough? Moving everything two squares to the right (or six squares to the left) makes full use of the torus-board. PS. Are there any freeware programs to check cylinder-board problems. (2017-12-11)

In bereits 9 Halbzügen kann die geforderte Stellung erspielt werden, wobei die Bedingung Annanschach gut genutzt wird. Überraschenderweise wird die weiße Dame nicht auf ihrem Ursprungsfeld geschlagen. Ein schöner Abschluss dieser Beweispartie ist die Annanschach-spezifische Rückversetzung des weißen Bauern c4 auf die Grundreihe.

Henrik Juel: To show that 4.5 moves is the length of the shortest proof game, one must also check shorter lengths, I think
Popeye uses 3 minutes to verify that no proof game in 4.0 exists (2017-12-11)

Autor (selbstkritisch): "En éste la clave concede un escape al rey contrario en 6 D. La batería 4 C R - 4 R - 5 A D [g4-e4-c4] trabaja en las tres siguientes variantes: D X C, C 6 D y R 6 D [1. ... Dxe4+, Sd3 und Kd3], esta última un típico efecto de desclavada con el rey negro, que ha sido introducido por la clave. Contra ésto, tenemos que la variedad del juego de defensa es, en relación al número de piezas existentes, muy pobre, y que la disposición de las piezas en el flanco dama es, por cierto, antiestético.

'HN': "Eine nette Idee! Aber mit Widmungsaufgaben ist's eine eigene Sache. Die Löser mögen prüfen."
- Heutzutage kann der Computer das Prüfen übernehmen, die letztendliche Entscheidung, ob der oben erwähnte Makel ("Co-Dual = ein vom Computer entdeckter Dual, der den menschlichen Lösern/Prüfern entgangen war) einen ernsthaften Defekt darstellt, muß aber auch heute noch der Mensch übernehmen.
So Henrik and Co., do your Job! :-)
