Henrik Juel: Completing the key isn't legal, 1.'Rd1'/'-bPc5'/'e8S'+, but omitting the promotion in the mating move is, 1.Sxe7+ Bxe7 2.'f8'#. Excellent joke. (2003-09-19)
James Malcom: A very witty joke Valladao! (2020-09-24)
A.Buchanan: Really like this joke (2020-09-25)
Henrik Juel: To see the illegality of completing 1.fxe8=S+?, note the captures:
Black captured fxDe, so [Pg7,h7] were captured on their files, while the other six missing black men were captured by white pawns
The illegality of completing 1.0-0-0,bxc6ep? is rather obvious (2020-09-26)
James Malcom: And for those you don't find it obvious: If the White king hasn't moved, then where did wRa5, and wBb8 if bPb5 has just done a double-step, come from? Neither can be promoted pieces, as White still has all eight pawns. Trying to finish castling and en passant therefore both produce illegal positions and thus cannot be the solution. (2020-09-26)
Henrik Juel: Continuing beating the dead horse...
How does the white player actually perform an entire move?
1.0-0-0+: Ke1-c1 and Ta1-d1
1.bxc6ep+: Pb5-c6 and remove sPc5
1.fxe8=S+: remove sYe8 and Pf7-e8 and replace wPe8 with wSe8 (three fractional actions)
2.f8=Y#: Pf7-f8 and replace wPf8 with wYf8
So a marginally better stipulation might be: 'White to move mates in less than 2 moves' (2020-09-26)
A.Buchanan: I've tried to set up some intermediate diagrams to allow us to show the animation, but the pieces seem to move even for words which are not moves (and marked italic/red). It's quite baffling. It's almost as if someone with privilege has gone in the background and assigned moves to those dead words. If so, that's extremely unhelpful. Gerd was quite active on this site for a month in German lockdown, for which I'm grateful, but one key task is still waiting: to empower the editors by documenting exactly how the animation decides what to do based on the diagram(s) and stipulation. (2020-09-27)
A.Buchanan: The PDB stipulation field should be non-text form to drive the animation. Where the stipulation is non-standard, there should be a Unicode representation of the original, and translations into German, English and French. But cannot overwrite any original non-standard stipulation, in my opinion, as it is part of the composer's work. (2020-09-27)

Cook: 1. h7! leider
Der Cook war schon nach der Erstpublikation bekannt:
'De Amsterdammer' 16.09.1900: "No. 528 laat nevenopl. toe (h7 enz.)" und schlägt zur Korrektur vor: "Wij meenen dat dit euvel aldus te verhelpen is: Wit Kc4, Tc7, Lc8; p. b6, e7 en f3. Zw. Kd6, p. b7. Mat in vier (4) zetten." (Korrektur s. P1375151 sowie weitere Korrekturvorschläge P1372391 und P1375040)


Am 23.09.1900 wurde dann auf die Kritik des bekannten Problemomponisten den Hertog eingegangen: "De heer Den Hertog maakt ons opmerkzaam dat de vierzet van de Savornin Lohman niet correct is, daar de eerste zet (d8 en blijft pion) tegen de regels der probleemkunst zondigt. Deze regel was ons en eenige probleem-componisten, die wij 't probleem voorlegden, niet bekend. Bij 't oordeel van een autoriteit als de heer Den hertog leggen wij ons echter gaarne neder."
A.Buchanan: J.Savournin (who only has 1 problem in PDB) is not to be confused with the much more prolific Jacques de Savournin (b.1930) (2020-04-26)
Mario Richter: 'Wiener Hausfrauen-Zeitung' gives the author's name above the diagram as "J. de Savornin', please notice, that there is no 'u'! ("Savornin" is repeated at the solution some weeks later.)

The source is given as "Weckblad" (not "Wedblad"!), which I think is a typo and should be "Weekblad" refering to some weekly publication from the Netherlands (perhaps 'Algemeen Handelsblad'...) (2020-04-27)
A.Buchanan: Hi Mario, thanks for your scholarship.
(1) This is the only "Wedblad" composition in PDB, so I will change it to "Weekblad". There are three specific Weekblads in PDB: Algemeen Katholiek Weekblad,
Amsterdamsch Weekblad, Bloemendaalsch Weekblad.
(2) Looking at the change records for these two composers, it seems they were conflated earlier, and have been teased apart. I think the "de" belongs to J.Savornin not Jacques Savournin, about whom we know more, and I find no mention of "de" for him.
(3) Yes "u" only for the younger one. (2020-04-27)
James Malcom: The c & k in the typo source are rather hard to distinguish: http://anno.onb.ac.at/cgi-content/anno-plus?aid=whz&datum=1901&page=129&size=45. Mario, on which page does the solution appear? (2020-04-27)
Mario Richter: Solution see http://anno.onb.ac.at/cgi-content/anno-plus?aid=whz&datum=1901&page=170&size=45

Regarding the "Weekblad" question, there are many more possible candidates in the PDB, e.g. 'De Amsterdammer' (also known as 'De groene Amsterdammer'), which carries the subtitle "Weekblad voor Nederland", there are also other sources perhaps yet not in the PDB, e.g. 'Weekblad voor Indie' (which had around 1914 a big chess column).

I checked my own local archives, but so far I only found chess columns with problems of the "younger Savournin" ... (2020-04-27)
Mario Richter: In the meantime I have found the original source. The author is given as "E. J. de Savornin Lohman", I have no idea, how this is correctly entered into the author table ... (2020-04-27)
James Malcom: Is it possible to link it Mario?

Also, I fixed the author name. There is the field “Addition”, below “Country”, that is for middle names. I played E. J. as the first name, Lohman as last, and the rest in the middle. (2020-04-27)

James Malcom: Many thanks for the links and great research Mario; it is great to actually know know the and see the original source. I will continue to search for more dummy pawn problems in the meantime. (2020-04-28)

'Palestine Post':
"If the promoted pawn on Q8 is converted into any piece, Black is stalemate either immediately or in the second move, thus: 1. cxd8=T L--B4+ 2. TxL,KxL patt 1. cxd8=S L--B3+ 2. PxL patt

Will solvers note that the making of second king is against the rules."

Löser R.W. Johnson: " I felt convinced the old gentleman had been taking advantage of the chess law which enacts 'that every pawn on reaching the eighth square of the board must be immediately exchanged for a queen or *any* other piece the player may think fit'; and this little word 'any' was at the bottom of the mystery.
Now a triple check may be effected in two ways - first by exchanging the pawn for a new king, and secondly by substituting one of the adverse pieces which shall give check, for the pawn advanced to the eighth square.
Actual experiment upon the position given, convinced me it must be effected by the first method ..."
Originalforderung: White to move and mate himself in five moves by 'The Triple Check!'

Eingebettet in eine Erzählung "My Uncle's discovery"

vgl. P1340371 und P1340408
A.Buchanan: I think the definition of Rex Multiplex in the glossary could be better. Looking for suggestions. Is parrying one of the multiple checks sufficient, e.g. if 3. ... gxf8=S? then 5. ... Sd7,Sxe6 would block one check. So it must be 3. gxf8=B,L - still a cook though. If a player leaves one king in check in Rex Multiplex, can it be captured? (2020-05-30)
James Malcom: Andrew, it is an intentional dual, and not a cook, acknowledged by the author. On page 14 the text states: “and at last my uncle acknowledged that claiming a knight or bishop effected the same object, “but it is my pleasure that I claim a pawn,” he said almost sternly, and I could not beat that logic, I allowed his solution to proceed.” Link: https://books.google.com/books?id=BWRfAAAAcAAJ&pg=PA3&dq=dummy+pawn&hl=en&sa=X&ved=2ahUKEwjAt4OHxYjpAhXXAZ0JHYfRATg4ggEQ6AEwAHoECAEQAg#v=onepage&q=dummy&f=false (2020-05-30)
A.Buchanan: Yes but what does Rex Multiplex mean? Then let's look at the problem. Retro Corner defines it as:
"In Rex Multiplex, a pawn can also promote to king, so more than one king of the same color may be present on the board. A move, giving check to different kings, is allowed only if all checks can be parried on the next move. Mate can only be given if all kings are mated in the same move. In parrying a check or a mate for a part of the attacked kings, it is not allowed to expose any other king of own color to any (additional) check or mate. In case there is no other move of defense available, either the position is mate or the checking move was illegal."
I don't understand this at all.
Then it seems as if Rex Multiplex is a proper fairy format, not a joke. How many of the "joke" promotion problems fit fair-and-square into this? (2020-05-30)
Henrik Juel: Rex Multiplex is a fairy condition, invented long after 1873, I believe, so it is not in effect in this joke problem (2020-05-30)
A.Buchanan: ok thanks Henrik, that answers the second question. How about defining Rex Multiplex? (2020-05-30)
Henrik Juel: The Retro Corner definition seems reasonable, but the Schwalbe definition is more succinct:
Beide Parteien können mehrere Könige und/oder königliche Steine besitzen und auch in einen König umwandeln. Ein Schachgebot ist nur zulässig, wenn es entweder für alle Könige zugleich parierbar ist oder alle Könige gleichzeitig mattsetzt. (2020-05-30)

'The Chess Player' 27.09.1851, Heft 11 S. 84: "The solution of No. 19 is Pawn takes Rook, remaining a pawn. It may seem ridiculous to many chess-players, but we think candidly that, when first the rules were laid down, nobody thought of such a case, or else the rules would be a little more precise on that point."
This is the second oldest known example of the dummy pawn, and the first study For the oldest, see P1375382.

Original-Diagrammüberschrift: "Revolutionary Question XIX. How can White draw?" und als Forderung: "White having the move can draw"
Die 'Westminster Papers', 01.12.1873, S. 175 schreiben: "After mature consideration, we can see no utility in a controversy about the dummy pawn. So far as we know, it was first suggested in this country in 1851, in a two-penny publication called the Chess Player, and was illustrated by an absurd problem, aptly enough baptized by the composer “Revolutionary”. The problem, which in 1851 passed current for a tolerable joke, was in 1862 “adduced” as a serious argument, and appears to have convinced some worthy people that it embodied an excellent principle. To J.M.R., who enquires, “Could not a game be invented to show the usefulness of the regulation?” we answer, yes; and more, the players might be invented also. The wonder is, that the double event has not been “managed” long ago."
Mario Richter: Perhaps the oldest problem with a dummy pawn, but the chess literature knows of earlier examples at least in chess games (e.g. because of the rule that a pawn can promote only to pieces which have already been captured [what I would call a "dormant pawn"]). (2020-02-11)
James Malcom: Agreed. Although the difference is whether or not the dummy pawn is allowed to promote later of not. Refer to the “Single Box” ruleset. (2020-02-12)

In 'Regles du jeu...' heißt es zu dieser Stellung:
"Avant quitter ce sujet, nous devons dire que Mr. Pétroff nous a communiqué le problème suivant, dans lequel, en supposant les meilleurs coups possibles de la part des noirs, les blancs ne pourraient remettre la partie, que s'il leur était permis de refuser toute promotion à leur pion entré à dame, c'est à dire de le laisser pion.
...
A cette occasion, Mr. Pétroff nous prie de soumettre au jugement des autorités européennes en matière de jeu, s'il ne conviendrait pas d'introduire dans le règlement une clause qui permît au possesseur d'un pion entré à dame, de renoncer à tout accroissement de ses forces, en laissant ce pion inactif et immobile, comme pion, jusqu'à sa prise ou jusqu'à la fin de la partie? Cette clause pourrait être appuyée par les considérations ci-après:

a) Que les situations dans lesquelles un pion est changé en fou ou en tour, ne sont guère plus fréquentes, ni moins extraordinaires que celles où il peut être utile de le laisser pion;

b) Que s'il est loisible au possesseur du pion entré à dame, de l'élever à un rang inférieur, comme celui de la tour, du fou ou du cavalier, il doit être libre également de refuser au pion toute promotion, si les circonstances l'exigent.

De son côté, la Société des amateurs d'échecs de St. Pétersbourg n'a pas cru pouvoir se ranger à cette opinion (exprimée sous forme de doute par Mr. Pétroff lui-même), contraire au principe fondamental du jeu, qui n'admet point l'existence de pions aux bandes de l'échiquier occupées primitivement pas les pièces."


In 'Chess Praxis', the texts reads before the diagram "The following problem is offered by M. Petroff as an instance where White can draw the game by allowing a Pawn to a Pawn after it is played to the eighth square, but otherwise cannot prevent a loss."
Mario Richter: Stupid question: What happens if Black plays 2. ... Sf4?, i.e.
1. a6 Sd5 2. axb7 Sf4 3. bxa8=B Sh3! or 3. bxa8=D Sd3! (2020-02-12)
James Malcom: You’re right Mario. The problem is cooked. With Sh3, White is no longer be stalemated and black easily wins. (2020-02-12)

In der 'New Zealand Mail' (21.04.1883) heißt es zu diesem Problem: "This position has been composed by Mr. Collins in accordance with the British Chess Association’s 13th Law : —“When a pawn has reached the eighth square, the player has the option of selecting a piece, whether such piece has been previously lost or not, whose name and powers it shall then assume, or of deciding that it shall remain a Pawn.” This rule of the “dummy pawn” has never met with much favour amongst chess-players, and there are very few clubs or societies which observe it.
We have received no correct solution to the problem (which is a most ingenious one), the result doubtless of the non-acquaintance by our friends of such a rule as the foregoing in any of the codes of chess laws."

Alfred Pfeiffer: Bis 1904 war nach den Regeln eine "Umwandlung" in Dummy-Bauer erlaubt.

1862 British Chess Association rule:
"Code of Laws of the British Chess Association" In that code, Law XIII said, "When a pawn has reached the eighth square, the player has the option of selecting a piece, whether such piece has previously been lost or not, whose names and powers it shall then assume, or of deciding that it shall remain a pawn."

Die Umwandlung in Dummy-Bauer wure erst 1904 offiziell abgeschafft. Daher würde ich bei Aufgaben aus jener Epoche nicht von "Scherzaufgaben" oder "Umwandlungsscherzen" sprechen. (2020-02-12)
James Malcom: While you are correct, it is the best possible classification for them in the modern era in my opinion. We shall speak of them as such, but shall we at least classify them as such? (2020-02-12)
Mario Richter: Alfred is only partially correct: this strange Law XIII was only valid in the British Chess Association - many other countries had rule sets without allowing dummy pawns (e.g. Germany, Russia, France, to name a few). Or to put it with the words of the 'Philadelphia Times' 03.01.1886 p.7: "the 'Dummy pawn' code of 1862 ... , has never, outside of a very limited circle, received any recognition."
I have nothing against the classification as "joke" and "joke promotion", since we're classifiying the problems from a today's perspective.
In an alternative for is to be found, Daniel VanArsdale, in his Web-article about Loyd's dummy pawn problem (P1265742) uses the term "Liberated promotion" (s. a href="http://www.silcom.com/~barnowl/Sam_Loyd%27s_Dummy_Promotion.html"http://www.silcom.com/~barnowl/Sam_Loyd%27s_Dummy_Promotion.html/a) (2020-02-12)

Chess World, Pages 220-221: “The next problem is sort of a correction to the first [P1372941], and it is framed in the conformity of the rule, that when a Pawn has reached the eighth square, the player has the option of “deciding it shall remain a pawn to the end of the game.”

The amended position, it will be seen, admits still of the original mate in three moves, according to rules observed by all the Chess world, except for a few English clubs; but under the recent code it is soluble in no less than five:-

von Pavitt als Beispiel dafür konstruiert, daß die auf dem Londoner Schachkongress beschlossene Änderung der Umwandlungsregel für den Britischen Schachverband (d.h. die Möglichkeit der UW in einen "dummy pawn") auch Auswirkungen auf die Schachkomposition hat:
1. Probleme, die nach den alten Regeln korrekt waren, können inkorrekt werden (wie dieses)

The idea of a dummy pawn promotion in a r# has certainly been done already, but I do not know of any predecessors, and it most certainly never been done at this scale before.
A.Buchanan: I think this is very original and good: do you think of publishing in magazines at all? One nit: it seems that their are multiple mates after the D promotions. D can go to the squares for R or B mates. So can't really say that the refutations are distinct, in my humble opinion, so for me this isn't quite a double allumwandlung. What am I missing? (2020-04-26)
James Malcom: Many thanks. I have thought publishing in a magazine, yes; I have made problems that have never been shown. But I have always been unsure of how and where. The refutations are not meant to be unique-they are merely meant to be there. (2020-04-26)

Version of P1375151.

Curiously, the cook in Lohman's original P1216212 can be fixed by putting a dummy pawn on h8! However, Lohman's correction P1375151 by shifting the other pieces to the left avoids being mated on what was the h-file.

However I prefer to replace bPc7 with wPc8. This echoes the principle (due to Erich Bartel?) that in a fairy problem, one can promote to anything which is actually on the board. But actually, this is neither a fairy problem nor a joke.

Promotion to dummy pawn was actually legal in many tournaments from 1862-1904 (although admittedly some people were apoplectic about it. One staunch advocate was world champion Wilhelm Steinitz. See:
https://en.wikipedia.org/wiki/Promotion_(chess)#1862_British_Chess_Association_rule
https://chess.stackexchange.com/questions/21212/when-if-ever-was-it-a-rule-that-pawn-promotion-was-optional/21214#21214

The "Golden Age Principle" says for any problem, you look through the chess timeline and if there is any period when rules or conventions made the problem sound or a record-holder, then it continues to be considered sound or record-holder. In the case of records, it means that there may be multiple record holders. So dummy pawn problems are orthodox problems, but need a new non-pejorative tag: I suggest "golden age". This is not frivolous, but is intended to help with other tricky issues like whether castling zeroes the count for the 50-move-rule. Note that if the dummy white pawn was on any rank except the 8th, the problem would indeed be fairy or illegal.

So GAP is insurance for old problems. But it's more than this: as long as problems are seen as being vulnerable to being cooked by changes in rules or conventions, we can't change rules or conventions, so we can't track the evolution of FIDE rules properly and we can't fix holes in the conventions.

"I am decidedly of opinion that the dummy should be allowed in the construction of Problems, at the option of the composer, as it would tend to lessen the difficulties to be overcome in certain positions, and as M.

Pawn On 8 In Chess Problems

“ I claim, therefore, P on 8 in Chess strategy, and conclude this paper with a problem commenced in July, 1879, and which I have only succeeded in making sound by the introduction of Dummy. If K on B 8, or no man at all on that square, then 1 Q to K R 4, or 1 Q to B 8, and mate in two more moves. Dropping the men one square down the board also produces a cook, in fact the dead pawn saves the problem from being relegated to the waste basket. I consider this one of the best compositions I have put together during a practice of thirty years, and I fail to see why it should be treated to Lynch-law, when the queen ing-a-pawn rule is to " reward it with the greatest possible advantage." I say it advisedly, that should Blackburne, Steinitz, or Zukertort ever play a match game in which promoting a pawn would lose the game, whilst leaving it dead would draw it, they would unhesitatingly refuse promotion, quoting the B. C. A. laws, by which they are governed in their ordinary play.” - Pages 32 & 33

The source, if not from the mentioned lecture in section one, is unclear

In February 1924 Laws gave a lecture to the BCPS consisting of his reminiscences of nearly fifty years’ involvement in the chess problem world. The text of this lecture follows:

Recollections 1877-1924. by B. G. Laws. Before Diagram #24

“Some fifteen years ago Godfrey Heathcote occasionally came to London, when he took the opportunity of seeing me. At one of our meetings he set up a three-mover he had just finished. To his surprise I altered the position a little to agree with the result I had previously arrived at, but without the aid of a black dummy pawn it was unsound. I was anxious to retain a sporty variation which was not in his. He at once decided to efface his work, hoping I should get mine right, as to which he had doubts. He was correct; I never succeeded.”
Henrik Juel: Slightly damaged by mate duals in the threat variations
tiny typo: threatens in german is spelled droht,
but your german notation is perfect, James (2020-04-29)
James Malcom: Thanks, I have improved over time. And I will keep the spelling of “droht” in mind. Fun fact: My learning of German notation was unwittingly documented on the net: https://chess.stackexchange.com/questions/24080/help-i-cannot-understand-this-game-s-notations (2020-04-30)

Henrik Juel: The minimal number of black pawn moves is 17, e.g.
a7-a5xb4xc3xd2, b7xc6xd5, c7xd6, e7-e5xd4, f7-f5xe4xd3, g7-g5-g4xf3xe2xd1,
so maybe a proof game in 17.0 is possible (2020-07-05)
A.Buchanan: It should be possible to get non-unique proof game in 17.0. One trick is that e.g. c7-c5xd4 and b7xc6xd5 saves a move. Also should be possible to castle wK out of danger so don't need an extra Wh move for that. Bl obviously needs a minimum of 1+2+3+4+5+6 - 4 = 17 moves, but curiously Wh seems to need exactly the same minimum. Therefore Bl will be the one building the pawn stack not Wh. However, making it unique can be quite tough. There is a unique PG by Nicolas Dupont in PDB which stacks 6 Wh pawns on the e-file. It might be possible to constrain the search space by having it as "orthodox joke" in e.g. 16.75, so the last move is e.g. 17. ... fxe1, but not completed this move by trading in the pawn for whatever piece it might be. (2020-07-06)
A.Buchanan: On keyword usage: I think under-promotions only happen in direct mates & studies. If we want to track the promotions, Dummy Pawn is a fundamental promotion type like (C-F), non-standard material, prenix & phoenix. In the long run, we should fully populate the keyword Promotion which lists all the promotions in order, but that should be populated automatically (2020-07-06)
A.Buchanan: The Dupont 6-pawn stack is in P1004108. Note that it takes 20.5 moves, substantially more than the 13 Wh pawn moves required to reach the final position. (2020-07-06)
James Malcom: A game of 16.5 moves is claimed in the Synthetic Proof Games booklet, but no game is given, on page 10.

https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.mayhematics.com/p/syntheticgames.pdf&ved=2ahUKEwiQksHz2LnqAhUTG80KHfedB1kQFjABegQIBRAB&usg=AOvVaw0uQQXduxnU1i61K_e0ryCW (2020-07-07)
Henrik Juel: 17.0 is actually quite easy, with three white moves to spare, e.g.
1.Sf3 g5 2.Sd4 g4 3.f3 gxf3 4.Sc3 fxe2 5.Sd5 exd1 6.b4 a5 7.La3 axb4 8.c3 bxc3 9.Ld6 cxd6 10.0-0 cxd2 11.Tf6 b5 12.Te6 fxe6 13.Tc1 exd5 14.Tc4 bxc4 15.Kf2 cxd3 16.Kg3 e5 17.Kh3 exd4
So 16.5 should also be easy by reversing the colors and building seven white pawns on the d-file, with a couple of black moves to spare (2020-07-07)
James Malcom: How ca White castle of Lf1 has not moved? (2020-07-07)
Henrik Juel: or, How can Black capture 15... cxd3 if d3 is empty?
Answer: I forgot to play Lf1-d3, so you must add this and permute some of the other moves, e.g.
1.Sf3 g5 2.Sd4 g4 3.f3 gxf3 4.Sc3 fxe2 5.Sd5 exd1 6.Ld3 a5 7.b4 axb5 8.c3 bxc3 9.0-0 cxd2 10.La3 b5 11.Ld6 cxd6 12.Tc1 e5 13.Tc4 bxc4 14.Tf6 cxd3 15.Te6+ fxe6 16.Kf2 exd5 17.Kg3 exd5
So there are only two white moves to spare
Still, you can probably write down a 16.5 move game with a white pawn stack, James (2020-07-07)
Henrik Juel: tiny typo: one of the last two black moves should be exd4, of course (2020-07-07)
James Malcom: Thanks Henrik. I added in the reverse as P1377635, if you don't mind. (2020-07-07)

This is the earliest known dummy pawn problem. See P1372387 for the oldest known study.

"A question of great importance,-one which is not provided for in the laws of the game of Chess, and to decide which we know of no precedent-is here involved. Can White force Checkmate in five moves? That's the question." -Page 113


"In some cases, therefore, the functions with which a Pawn thus situated could be in vested. would tend very materially to promote his master's interests; in others, perhaps to a less degree, he may, for instance, serve sometimes to embarrass the movements of the enemy's forces; or perhaps, to afford a temporary shelter or protection to his surviving friends. Thus-

"Imperial Caesar, dead and turn'd to clay, May serve to stop a hole, and keep the wind away." -Snippet Of Page 165, which has much more information

Also see pages 136-139 for the correspondence aftermath of the problem.

Answer-it depends on whether or not a Black pawn has the right of refusing promotion to a piece upon reaching the 8th rank.

If not, the there is a mate in five moves (a). If so, there is no mate in five moves (b).
James Malcom: I have made an amazing find through my extensive online searches for dummy pawn problems. This is a dummy pawn problem, with a Black defensive promotion in direcmate, that came four years before across the Atlantic the famous 1851 Kling drawing problem (P1372387)! We all thought that it took time after the Kling one for more sophisticated things in all genres, but no, thing were already in directmate territory in 1847!

Also, although the #6 line in b) is not not mentioned at all in the book, the fact that there is a unique mate in 4 after the Black dummy promotion is surely no accident! (2020-05-02)
A.Buchanan: Congratulations, James! If it's not a joke, it's not a joke promotion, however. (2020-05-02)
James Malcom: Thanks! And yes, I overlooked that. (2020-05-02)

Taken from the German Wikipedia on underpromotion-https://de.wikipedia.org/wiki/Unterverwandlung
Henrik Juel: This is not really an underpromotion, but a non-promotion (2020-05-15)
A.Buchanan: Yes Henrik. PDB animation requires promotion notation =B, but the keyword is allusive here. I am not a fan of under-promotion keyword apart from studies & direct mates. And it's arguable whether an S promotion is ever an under-promotion. But life is too short to figure out a better way to represent it here. (2020-05-16)

Even though Black captures the white man on f8, promotion to DTLS will not work
First Schnoebelen with dummy pawn as the captured man, I would think
Very good, Andrew (2020-05-08)
Henrik Juel: Another first:
Never before was a problem commented in the PDB before it was published... (2020-05-08)
James Malcom: When Andrew messaged me this asking about a PG with two dummies, I came back almost right away with the same idea, albeit in a flawed form-1. a4 f5 2. a5 f4 3. a6 f3 4. axb7 fxe2 5. bxa8=Q exd1 6. Ke2 e6 7. Ke3 Qg5+ 8. Kd4 Qxg2 9. Qf3 Qxh1 10. Qxd1. Great minds think alike after all! The best way. I think, to have two dummies is to have one per side and have both kings make the same journey. An idea to make it all unique is the problem though. (2020-05-08)
A.Buchanan: Haha Henrik thank you. Well I'm in lockdown in Singapore, and it was 9-May already when I posted in Matplus. (2020-05-09)
A.Buchanan: Can claim that this is not Schnoebelen because the pawn wasn't promoted! Just remained as a pawn! But I'm sure the Schnoebelen theme was interpreted in a looser sense in 1860s. Although exponents in that era would have been baffled as to *why* the theme was termed "Schnoebelen", as Philippe was not yet born. (2020-05-09)
Henrik Juel: I am sorry to learn about the Singapore lockdown, but here the merriment has no bounds (apart from the notational dilemma: exf8 is not a promotion and still the PDB animation requires exf8=B) (2020-05-09)
Olaf Jenkner: If you consider each pawn move onto the 8th rank as a promotion then we have the Schnoebelen. (2020-05-09)

Henrik Juel: It is short for 'option nichttrivial 0 1', the most limiting option for (long) selfmates in Popeye, affording the fastest attempt to find a solution or a cook
It does not provide a real test, so if Popeye reports nothing, there may still be a solution
Here Popeye reports the intended solution only, but there may still be (complicated) cooks
The PDB has lots of selfmates, where this option 'finds no flaws', and later Gustav declares C+ (2020-05-30)

AB comment in Matplus:

"A new example of this steampunk theme, orthodox in 1862. I love the mottos from 19th century problems. They seem so cheesy and unnecessary, and underscore the difference in sensibility between their time and ours. And yet the language of chess problems themselves remains at base relatively unchanged since then. Dummy pawns are absurd and paradoxical, yet as the ultimate under-promotion they are very cool for composition. They are as fiddly and footling as en passant captures, but those came to occupy a special place at the heart of the retro genre. There's an extra thrill that comes for me as I imagine Howard Staunton incandescent with rage at the whole thing. And of course the dummy pawn theme offer so much virgin design space across all problem genres.

"The motto here does not refer to Homer's breakfast. Simpson's-in-the-Strand was "the most important venue in Britain for chess in the 19th century" (https://en.wikipedia.org/wiki/Simpson's-in-the-Strand). The "carvery" eat-as-much-as-you-want style is still a staple of British cuisine. The chess went away, but came back in 1980. I lived in London for several years, and it's ridiculous that I never visited. Mentioned twice in Sherlock Holmes (perhaps deliberate product placement) it's now on my bucket list that one saner day I can lunch there - I hope with other problemists?"
Henrik Juel: Very good, James and Andrew
The testing program looks dubious: the version number suggests Jacobi, but something like Popeye 4.83 seems more likely (2020-05-30)
A.Buchanan: Thanks Henrik: yes it's hard to concentrate sometimes. Jacobi only does help stuff, so couldn't manage a selfmate. It was Popeye. (2020-05-30)

Henrik Juel: Nice joke proof game with Schnoebelen and fake white castling
It would have been acceptable in 1862, except that proof games were only invented some 50 years later
I solved it by noting that there are two orthodox solutions in 10.0 moves, both with a 'wasted' move by the black king: Ke8-d7-c6/e6-d6
Interesting that it is testable by Jacobi (2020-06-17)
James Malcom: Good job solving Henrik. I couldn't figure out a real castling, so I did fake castling, which is just as good.

Jacobi can test such problems with the condition "promonly q r b s p," and it is treated like a normal PG with a little extra. (2020-06-18)
Henrik Juel: I think that a fake castling is better than a real one (2020-06-18)
A.Buchanan: I agree with Henrik. I like this proof game, as the two elements complement one another harmoniously, with no wasted moves (2020-06-18)

Henrik Juel: The position in the source has Pd7 on e7, and the game given there is not unique (2020-07-04)
James Malcom: Fixed, and the solution guess there is incorrect-I've added it in now. (2020-07-05)
A.Buchanan: Does it work with bKe8 instead? Now showcases the swap of bR & bB. Genuine castling is not a feature - it’s sort of neutral in my humble opinion and here it’s non-thematic.
As a separate q, I don’t suppose one can shift bPf7 to d7? Worth checking because would be cool to undouble the bPs (2020-07-05)
A.Buchanan: Yes with bKe8, no with bPd7 (2020-07-05)
A.Buchanan: On keywords: I think excelsior doesn't apply to proof game, because every promotion would be excelsior. promotions can be identified as: non-standard material, Ceriani-Frolkin, prenix or phoenix. Then other features like Pronkin, Donati, Schnoebelen etc. "Interchange" is the term currently in the directory for "Platzwechsel" - please suggest a better term for when pieces swap place. "Umnov" is slightly different, and although strictly "Platzwechsel" implies "Umnov", I don't think it's very interesting when just 2 pieces are involved: it's intended mostly for longer chains. Just my thoughts (2020-07-06)
Henrik Juel: Nice to see that you had your breakfast before commenting today, Andrew...
I agree completely
There is no better word for place-swapping than Interchange, I think (2020-07-06)
A.Buchanan: In German there is e.g. Fonktionwechsel and Platzwechsel, connoting two kinds of Interchange. The English is missing this aspect. Role/Place maybe. And perhaps Exchange or Swap? (2020-07-06)
Henrik Juel: The english theme definitions in FIDE Album 2010-12 include:
Exchange of function: two pieces exchange their functions (i.e. the roles they play) between two variations or phases
Interchange of squares: two pieces reciprocally change their squares
In german, things are combined by creating combined words; also in danish: Funktionsveksel, Pladsveksel
In english, you add more words, apparently (2020-07-06)

Henrik Juel: What is the joke, James?
Natch 3.1 found no solution (2020-08-26)
James Malcom: The solution has now been added in, Henrik.

This PG has two purposes.
1) It is another exploration of what themes be realized with the dummy pawn involves.
2) It is also to push the boundaries of how long a dummy pawn PG can be made. (2020-08-27)
Henrik Juel: Thanks, James
Apparently you also extended the proof game; the one I tested was in 10.5
The solution shows the Schnoebelen theme, by the way (2020-08-27)
Henrik Juel: You forgot to remove wPf2 from the diagram position (2020-08-27)

A.Buchanan: I think sLb1 is kind of anti-Belfort Any way to replace it with a Phoenix/Prenix knight? (2020-08-27)

As Andrew suggests, if sLb1 were a black knight, we would have Belfort (2020-08-27)

Chess4E71
1. h1 Kf2 2. Kh3 Sf7 3. Kh2 Sg5=
play all play one stop play next play all
Author's solution: Schema problem to show the idea. At first glance, h=3 seems completely impossible, even without the confusing fact that Black to move is apparently checking White. But this absurdity is what renders the problem solvable.

Law A1.2 tells us that if the player to move is already apparently checking or even checkmating the opposing king, then he is not allowed to capture that king, and must make another move. The assessment whether the opponent is actually checked or mated is made only when the opponent has the move. In normal chess, such a position is illegal, but it is no more and no less illegal than say wBa1 wPb2. Law A1.2, tells us that we can still play chess. (See Lese Majeste)

In Chess4E71 such "illegal" checks can clearly occur, but only in the starting position. Therefore no moves have been made in the game so far. In particular, bPh3 has never moved. Now Article 3.7b of the Laws of Chess says: "on its first move the pawn [...] may advance two squares along the same file, provided that both squares are unoccupied. So 1. h3-h1! is legal.

Now what happens to the pawn when it arrives on h1? Again we consult the Laws. Article 3.7e says: "When a player, having the move, plays a pawn to the rank furthest from its starting position, he must exchange that pawn as part of the same move for a new queen, rook, bishop or knight of the same colour on the intended square of arrival." The pawn began on the 3rd rank, so it would only promote when it reaches the furthest rank, namely the 8th rank (which it never can attain, under orthodox rules, but that's irrelevant). When it arrives on the 1st rank, it merely remains a pawn. I can almost hear the groans :-)

The rest of the problem solves itself. Or an engine does.

The recognition that BTM is delivering check in what must be the starting position is hardly retro reasoning, so the Article 17A bell does not sound to awake the demon of the Dead Position rule from his slumbers. Hence with a forward stipulation, we don't worry that there is no mate possible after B1 move.
Henrik Juel: groan (2020-08-30)
A.Buchanan: Hark, what’s that I hear? :-) (2020-08-31)
James Malcom: Hark, I hear the angels groan! Oh snark, I head their echos spawn!:-) (2020-08-31)
A.Buchanan: Jacobi does not yet support dummy pawns, alas (2021-05-11)

Das tapfere Bäuerlein
In Reih und Glied stand das Bäuerlein und wartete ungeduldig auf den Beginn der Schlacht. Endlich gings los. Kampfesmutig schoß es vor, e2-e4; es war ja ein stolzer Königsbauer. Bald war es im Zentrum des Gefechts und hielt den schwersten Angriffen stand. Rechts und links fielen seine Brüder, sogar Offiziere fanden den Heldentod, aber unerschütterlich drang das Bäuerlein vorwärts, e4-e5 hurrah!
Diesem kühnen Vorstoß war es hauptsächlich zu verdanken, daß die feindliche Armee geschlagen wurde. Der schwarze König hatte sich mit dem Rest seiner Getreuen in die äußerste Ecke des Schlachtfeldes zurückgezogen, seine Lage war trostlos [Diagramm].
In ihrer Verzweiflung warf sich die edle schwarze Dame den heranstürmenden weißen Truppen entgegen, um vielleicht noch durch ein Pattmanöver die ihrigen zu retten.
Das tapfere Bäuerlein war inzwischen bis auf die 7. Reihe vorgedrungen. Nun stand es vor der größten Aufgabe seines Lebens. Es sollte die feindliche Dame, die mächtige schwarze Königin gefangen nehmen. Dies wäre aber auch sein letzter Triumph gewesen, denn auf der 8. Reihe würde ihm sein Feldherr sicher den Abschied geben und für einen Offizier eintauschen. Die weißen Offiziere atmeten auf, der gemeine Bauer, der sich durch seine mutigen Taten der besonderen Gunst des Feldherrn erfreute, war ihnen schon lange ein Dorn im Auge.
Der Feldherr, der große Schachmeister, überlegte diesmal sehr lange.
Spielte er 1. exf=D so patt
oder 1. exf=T so patt
oder 1. exf=L so Sxf6+ 2. Sxf6 patt
oder 1. exf=S so Sxf6+ 2. Sxf6 Kxg7 3. L-e5 patt
Also kein Offizier konnte ihm jetzt zweckmäßig dienen, so entschloß er sich denn, den braven Bauer noch auf der 8. Reihe beizubehalten und, siehe da, er erreichte dadurch auf schnellste Weise den Sieg:
1. exf=B!! Sxf6
2. Sxf6 Kxg7
3. L-e5 K-g6
4. D-g3 matt
So war das tapfere Bäuerlein das einzige in der Geschichte des Schachspiels, das noch auf der letzten Reihe mit vollem Recht seine Wesensart beibehielt. Ehre seinem Angedenken!
James Malcom: Thank you for this marvelous find, Mario! This is another ingenious directmate in this field!. The stalemating ideas are very unique and pleasing. (2020-09-26)

James Malcom: The point of this PG was to make a true Belfort, after the lone bishop in P1379376 was pointed out to not be a true Belfort. (2020-10-28)
A.Buchanan: I think the notion of a Belfort piece is the foundation idea. Then the question of whether a composition is a Belfort is derived from that, and should include other criteria as well. The original tourney succeeded in launching this idea, but we are surely allowed to clean up the position definition. I will check in the Encyclopedia (2020-10-30)
A.Buchanan: Belfort is not in the Encyclopedia! (2020-10-30)

Henrik Juel: Definition of the Royal Dynasty condition from Schwalbe
Königsdynastie: Im Diagramm kann jede Partei keinen, einen oder mehrere Könige haben. Ein König ist genau dann königlich, wenn er der einzige König seiner Partei ist. Eine Bauernumwandlung in einen König (derselben Partei) ist erlaubt. Ein König darf nur dann rochieren, wenn er königlich ist und nicht gezogen hat, seit er zuletzt königlich wurde. Die anderen für die Rochade vorgeschriebenen Bedingungen bestehen weiter.
In this problem 10.h8=K makes both white kings non-royal, so 11.f4 is not an illegal self-check
The black king is royal throughout, so 5.exf8=KDTLS? would have given a disturbing check to him, leaving just 5.e8=B
It is nice that both conditions are invisible in the diagram, but they should be mentioned in the stipulation, I think (2021-08-30)
Henrik Juel: Euclide 1.01 reports no solutions in orthodox chess (2021-08-30)
