Weiß hat den Damenturm vorgegeben und ist berechtigt, ohne den Turm mit Ke1-c1 zu rochieren. Der auf a1 stehende Turm ist vom Königsflügel herübergekommen.

James Malcom: Wrong source and author!
C. Planck merely got it from a friend and it was reprinted in The British Chess Magazine in his letter to the editor in the March 23, 1901 issue-https://www.google.com/books/edition/The_British_Chess_Magazine/mZlJAAAAYAAJ?hl
Quote: "This afternoon the following curiosity was submitted for my examination. I unfortunately omitted to learn where my friend got it from."
The 1910 books, is indeed in there, gives the wrong information0https://www.google.com/books/edition/150_Schachkuriosit%C3%A4ten/NVzzAAAAMAAJ?hl
Luckily, in a short afternote on May 7, Planck mentions that the solution has recently been given in The Pleasure Hour. It can be found here-https://hdl.handle.net/2027/mdp.39015068398471
I found the solution on page 544 in April, not surprising that it was mentioned in May due the the "slowness" of the day. It gives the solutions for the February problems.
Jumping back to page 362, it appears as an original problem by B. G. Laws.

Originalforderung: White mates in two - with the Knight at KKt6.
Motto: "A La Napier"
A.Buchanan: It's easy to make a miniature ideal mate version of this cheeky problem, e.g. 8/6pk/3N1PN1/6P1/7K/8/8/8 but the charm of Marshall's original is the apparently pointless wSb1 (2020-10-21)

1. Dc4-g8!
Mario Richter: Cook: Schwarz hat keinen legalen letzten Zug (2014-05-25)
A.Buchanan: This is not a retro problem. If we grant Black first move, then 0. ... Txb7! refutes. It's just a technical oversight. I can find no correction in PDB or WinChloe. Observe that sBb6 serves no purpose. If we remove it, then wLb5 serves little purpose. Removing both units, and shifting wD to e1,e5,e6,g6 or h5 retains soundness, but gives Black a last move. All variations persist, including the minor dual after 1. ... Lxb7, where both mates are separately forced. I prefer wDe6, because the key defending Sc8 is otherwise too strong. Also note the try 1. Dg8? In summary therefore: correction krN5/pN6/b2KQ3/8/8/8/R7/8 #2. (2021-10-09)
A.Buchanan: WinChloe gives a different original source, Wiener Schach Zeitung, with the same year 1932, towards the end of Keeble's chess problem career. (2021-10-09)
Mario Richter: My guess is, that the publication in 'Wiener Schach-Zeitung' is only a reprint as part of what I call "a real solving competition" (since amongst the problems to be solved there were also [intentionally] some with severals cooks or with seemingly or real illegal positions):
"Aus dem diesjährigen internationalen Lösungswettkampf.
Diesem Turnier ... lagen zum Teil sehr knifflige Probleme zugrunde. Es sei für unsere Löser vorausgeschickt, daß die Aufgaben zum Teil mehrfach nebenlösig sind, mitunter eine partieunmögliche Stellung vortäuschen oder auch haben. Die Illegalität der Stellung ist zu beweisen." (2021-10-09)
A.Buchanan: Wow, thanks Mario! This is a great example then of how one can't understand a problem sometimes, without knowing the context in which it's composed. How should we classify this one here in PDB? (2021-10-09)
A.Buchanan: Since illegality is the intention, it's not cooked. And it's a joke. bBb6 is a weasel. So much is clear, but I am uncertain whether to use the descriptive keyword "illegal position" or "no legal last move for black" or something else. The latter is actually a retro-stalemate (defined as a one-sided illegal position). However, 'retro-stalemate' as a keyword it has the sense more of applying to retro compositions where a retro-stalemate is sought in the history of the game, not Article 15 cases where the diagram is already one-sidedly illegal. So I think we should keep the keyword 'no legal last move for black'. (2021-10-10)

Aus der Lösungsbesprechung (entnommen aus dem Jahrbuch 2001):
Sie haben sich nicht verguckt: 0-0-0-0 für eine überlange Rochade auf der Vertikalen. Frühere Fassungen der FIDE-Regeln ließen bei 'böswilliger' Auslegung diese Rochade mit einem Umwandlungsturm zu - aber natürlich nicht in der Praxis. Jedenfalls griffen einige Komponisten diese Möglichkeit für Scherzaufgaben auf. In der Nr. 1772 wurde sie m.W. erstmals im Hilfsmatt eingebaut. Die gegenwärtigen FIDE-Regeln lassen die Scherz-Rochade aber nicht mehr zu, wie unsere Experten denn vehement reklamierten: Der König kann nur mit einem Turm auf der gleichen Reihe rochieren. Streng genommen ist damit die 2. Lösung inkorrekt. Als Silvesterscherz war sie dennoch ein geeigneter Probierstein des Punschgeistes!
A.Buchanan: WinChloe rokagogo has 220 solutions - but 218 of these are fake: with either Tc1-e1 or Tc1xe1 followed by castling, legal under rokagogo but not P-K. Need to filter the 220 solutions using Excel, but there is no doubt that the problem is sound (2021-01-06)

[story continued from P1381572]
The Eye begs to submit to Derbyshire the following problem in reply. We confess to being fairly out-generaled by the wonderful maneuvers disclosed in the three mover. We have no doubt that its talented author will find little effort much more easy. We respectfully dedicate it to him. The art of problem composition will now, no doubt, undergo considerable change. For instance, you might slip the Black king into your pocket, or knock your adversary down-all admirable methods of mating in one. Our problem has been composed in anticipation of a new era.
Olaf Jenkner: Die Aufgabe ist unlösbar.
Stimmt die Stellung? (2012-06-10)
James Malcom: The position is correct-see https://news.google.com/newspapers?nid=Z8CpXElfgm4C&dat=18790213&printsec=frontpage&hl=en
However, the reprint in itself is perhaps a huge error. The paper seems to give the solution to each problem the next week, but I found that they skipped the number 589 in their next issue. (2020-11-06)
A.Buchanan: What about later issues? (2020-11-06)
James Malcom: I checked the whole of February and March already, and nothing is there, but it may be that I missed it, I admit. (2020-11-06)
James Malcom: Wait, I did miss something! In the Feb. 27th issue: https://news.google.com/newspapers?nid=Z8CpXElfgm4C&dat=18790227&printsec=frontpage&hl=en
Under "Waterbury Owns Up" in which there is an address to 588, the correction of an earlier publication, this is said "I hope that 9-move hoax (No. 589) will plague the inventor. Yours truly, C.H. Waterbury"
And "Ayrshire Argus and Express" is actually not the original source, as the 2/13 issue says "Problem No. 589 By Editor Of Ayrshire Argus and Express." I've corrected this, and tagged this as a joke for now. (2020-11-06)
A.Buchanan: Ha! I echo Mr Waterbury’s sentiments! But was it originally published in April or Christmas issues? The letter does seem to imply some other dialogue which acknowledges the composition is a hoax. Mr Waterbury does seem to know it’s a spoof. And is there any meaning to the position? Very easy to make a diagram which doesn’t have a #9 (e.g. game array) (2020-11-06)
James Malcom: The #9 seems to have been made for the issue give in, as an after spoof of the far, far more interesting Christmas Joke above it, which I shall add soon! (2020-11-06)
James Malcom: Now see: P1381572 (2020-11-06)

1. DMa7-b6 White huffs b8 for not capturing R, when Pb8Q, a mischievous morsel.
A.Buchanan: original diagram have draught counters in it?
@Joost (resident checkers expert): Is incurring a huff regarded as illegal? There are many cases where this sacrificial play might be the only winning line? Do any checkers engines include huffing? (2023-08-11)
Joost de Heer: See https://en.wikipedia.org/wiki/English_draughts, huffing might've been allowed at one time, but it isn't in the rules now, and I doubt it was in the official rules in 1946. (2023-08-11)

1. exd6ep+! Kd3 2. 0-0-0+ Ke2 3. Tde1+ Kd3 4. Le4#
'(Endstellung einer gespielten Partie)'.
Frank Müller: Die korrekte Lösung lautet:
1. exd6ep+ Kd3 2. 0-0-0+ Ke2 3. Tde1+ Kd3 4. Le4#
Der ep-Schlag ist freilich nicht begründbar. (2017-09-09)
A.Buchanan: In 1852 there was not a single sound retro in the world (see P0002092 & P0001360). This makes no attempt at retro analysis. Maybe there was a story that went with this problem, as with P0002092, but at this stage who knows. I would describe this as joke, rather than cooked or no solution. (2017-09-09)
Henrik Juel: White can mate in four only if last move was d7-d5
if so, C+ by Popeye 4.61 (2017-09-09)
James Malcom: If a German reader/speaker may the original source is cataloged here: https://www.google.com/books/edition/Schachzeitung/U61AAAAAcAAJ?hl=en&gbpv=0
Perchance you can read it to translate whether or not this problem is described as a joke? (2022-06-29)
athulin: No joke problem. (And no story.) And if the editors had any particular ideas in mind, they do not appear to have been expressed; the solution just prints the moves. This suggests that it was more a question of finding the move, not of justifying it beyond being a position in an actual game, and that any reader would get it from the solution alone.
A kind of proto-retro. (2022-06-30)

James Malcom: How do you add in the author name exactly? It's Gyula Breyer. After about a month of not using my editing powers, here is the first problem I have chosen to enter in! I will be adding more joke promotion problems in here soon and classify them a little bit more. (2020-01-28)
Mario Richter: Fritz 6 gives
1. exf8=N+ Kxf8 2. Kd7 Ng5 3. Nc6 Bxe6+ 4. fxe6 Nxe6 5. Kxe6 Rg8 6. Nxd8 f5 7. Kf6 Rg6+ 8. Bxg6 hxg6 9. Ne6+ Ke8 10. Kxg6 f4 11. exf4 exf4 12. Nxf4
as a win for White (+7.44)
Can somebody with a stronger chess program find a better defense for Black? (2020-02-11)
James Malcom: It seems that 2. Kd7! is the one move that cooks this problem. The Black knight can’t move to release Black’s pieces as then Black will lose their bishop. 2. Nd7+ merely draws. (2020-02-12)
Peter Wong: Not only is there a cook, but the intention doesn't seem to work either. If you manually set up the position after 1.exf8=black queen for the Stockfish engine, it finds no clear win for White. (2020-02-12)
James Malcom: Well in the intention, if 1... Be7? then 2. Kc7 Qg7 3. Nxe4 Qg2 4. Nd6+ Kf8 5. Nd7+ Kg7 6. Ne8#. It's only after 1... Qe7 2. Nd7 Qex6 3. fxe6 Ke7 does it become a draw. It seems that all known tasks with White promoting to a Black queen are cooked. It should not be surprising, but it is indeed sad. Not even Bengston's draw study P1372297 is correct. It shouldn't be to hard to make a new, correct draw study, whether or not it's based on Bengston's work, but now a winning one seems further elusive as this seems to be the only way work of it's kind. (2020-02-13)
SP: After "1... Qe7 2. Nd7 Qex6 3. fxe6 Ke7" instead of a draw there is a mate in 5:
4.Sf5+ Ke6: 5.Lg4 Sd6,Sg5 6.Sc5+ & 7.Lh5+ or
4.-- Ke8 5.Kb7 (6.Kc8 & 7.e7) etc.
Did you perhaps mean 3.-- Le7? Breyer intended 4.Kc7: for that.

1. Kf7 e8=T! 2. Kg6 0-0-0-0-0-0! 3. Kh5 Kf4 4. Kh4 Th2#
The origins of this joke h#4, which utilizes Pam-Krabbe castling in a minimal form, was a mystery conjured by Per Olin, so far the only person who seems to actually know of it.
On the Internet, help was asked. On February 17, 2009, they sent a request for help on the Retro mailing list-ttps://pairlist1.pair.net/pipermail/retros/2009-February/002826.html This is what they said.
"Supercastling means castling with a promoted rook. Due to changed FIDE
rules it is nowadays illegal. It is said to have been invented by Max Pam, which inspired Tim Krabbe in 1972 (Hesse gives a different year) to compose a threemover including three different white castlings:
http://en.wikipedia.org/wiki/Joke_chess
_problem#Offbeat_interpretations_of_the_rules_of_chess
With the same supermove I composed a twomover (Stella Polaris 1975), Bengt Ingre has published a twomover (Mora Tidning 1993) and we have recently even seen an endgame study with this speciality.
Back in the good old seventies I was informed that there is a helpmate fourmover Ke1 pe7 - Ke8 (2+1) with the supercastling: 1.Kf7 e8T 2.Kg6 0000 3.Kh5 Kf4 4.Kh4 Th2#. Could be that as composer was mentioned Dawson, could be that it was somebody else. Could be that this is the first supercastling, could be that I have dreamt the whole problem.
Can anybody trace this problem?
Best regards
Per Olin"
It went unanswered. A decade later, on June 8th in the Matplus.net forums, they tried their luck again, but also to no avail-http://matplus.net/start.php?px=1582139891&app=forum&act=posts&fid=anti&tid=2302
Olin wrote: "Time wise this could have been inspired by the Krabbe problem. I have no memory of seeing that, but it could have been showed / mentioned in some meeting of the Finnish Chess Problem Society. What I vaguely remember is the following: (diagram) h#4
In an article in the magazine Suomen Tehtäväniekat, January 1994 I asked for author (Dawson?) and publication details, no response. The same question has been asked around one decade ago, probably here in Mat Plus Forum, no response. Question: can anybody trace the helpmate? - The solutions of both problems are obvious. - The chess rules of today say that castling is a move of the king and either rook of the same color along the player’s first rank; this was not the wording in the 70ies and earlier."
On January 4, 2021, a year and a half later, a reply was posted in the same thread to point exactly where they had asked a decade earlier (as aforementioned). Olin's reply, which currently stands as accepted, finally brings closure to this mystery: "Thanks! If the problem is nowhere to be found, then I must have dreamt it and attributed it by mistake to somebody else. Can I claim authorship?"
Now Per Olin has been credited as the author, properly and at long last. An exact source, if not the drifting memories of Olin's 1970's lost in time, is still quite the enigma, unless the 1994 reprint was the first time, which it likely may not be.

Henrik Juel: Here the extra joke is that the (dummy) pawn can move (2020-04-14)
James Malcom: The newly born black pawn is not a dummy pawn, in my opinion. Unlike the dummy, it still has the right to move foward in principal. Since it is new and has never moved, it sill has the right to make a double-step if allowed, as in Horde Chess (https://lichess.org/variant/horde). (2020-04-14)
Henrik Juel: I see your point, James (2020-04-15)
James Malcom: Seems that Gerd might have missed including pawns promoting to opposite color pawns the new update. I'll email him tomorrow morning. With accordance to the rules, they have 4 first moves as a 7th rank pawn does. (2020-05-03)
Gerd Wilts: Promotions to pawns are now also supported. (2020-05-03)
James Malcom: Many thanks Gerd! (2020-05-03)
A.Buchanan: I had missed these 6 miniatures: they are terrific! Can I ask to replace Sg8 in this one with L so that it's not giving check in the starting position. I guess it's kind of crass though economical to replace with pawn! (2020-10-13)
A.Buchanan: Dummy pawns can in principle move imho: it's just that they're usually blocked by the edge of the board. If one was teleported somewhere else on the board by some mechanism, then they would just start moving. So completely different kind of animal from a dummy, which genuinely cannot move :D (2020-10-13)

James Malcom: A weird fallacy indeed. More information is in lacking, however. (2021-01-08)

"Ok, you may say that this is all old stuff, very entertaining but with no relevance for nowadays chess. So? Well, look at this endgame study which circulated among the chess insiders in the 80s:
White to move and win - my version (from memory)
I believe I have read somewhere that the composer is from Dar-Es-Salaam, but I can not find sources for that.
The solution is: 1. Kf7, Nd6+ 2. g7+!, Kh7 3. g8D+ and mate next move.
Then you may object that white is in check, in fact a double check, when he unaffectedly moves his little pawn at the second move. Yes, he is in check BEFORE the move, but is he after? You see, at that time the rules stated that the king is in check "...when the square it occupies is threatened by one or TWO of the opponents pieces." So the check is elegantly parried by making the kings square threatened by THREE pieces!
Relax, nowadays the rules state that the square in question must be threatened by "... if one or more of the opponents pieces."

It still seems that there are castling loopholes in chess variants.
The rules for castling in Fischerrandom or 960-chess are:
" Castling, as in Orthodox chess, is an exceptional move involving both the King and Rook. Castling is a valid move under these circumstances:
Neither King nor Rook has moved.
The King is not in check before or after castling.
All squares between the castling King's initial and final squares (including the final square), and all of the squares between the castling Rook's initial and final squares (including the final square), must be vacant except for the King and Rook.
No square through which the King moves is under enemy attack.
The movement of the King and Rook during castling should be easily understood by players of Orthodox Chess:
When castling on the h-side (White's right side), the King ends on g1 (g8), and the rook on f1 (f8), just like the O-O move in Orthodox chess.
When castling on the a-side (White's left side), the King ends on c1 (c8), and the rook on d1 (d8), just like the O-O-O move in Orthodox chess.
Sometimes the King will not need to move; sometimes the Rook will not need to move. That's OK."
Now reading those rules as Devil reads the Bible the following seems possible:
(diagram)
Fischerrandom Chess, mate in 2. White king has not moved.
Solution 1.c8=R any 2.0-0-0 #
[White rook just moves to d1,all squares in the path c8-c1-d1 are free except for wK. The castling rook has not moved before ;)]

"NELS NELSON
We have heretofore published many of Nelson's fine problems and should like to show any readers the more humorous side of his talent. This winter our distinguished friend is spending his vacation in Los Angles. It is with his kind permission that we are publishing this story and problem.
Nels Nelson, born in Denmark in 1871, emigrated to the United States when 12 years of age. He learned the moves of chess in Denmark and began solving and composing problems in 1894. He was chess editor of the Minneapolis State Chess Asccostion, 1911-1912, president of the Minnesota State Chess Asccostion, 19229-1930, and lives at Hopkins, Minn., a suburb of Minneapolis.
AN APRIL FOOL JOKE
A certain celebrated chess master, who we will designate as Mr. "X," while on in the provinces happened into a tavern which was the mecca of the village chess players. Mr. "X," very fond of practical jokes, conceived a plan of springing on one of the unsuspecting natives. Professing ignorance of the game, the champion of the club offered to teach Mr. "X" its intricacies. After showing Mr. "X' all of the moves with the exception of pawn promotion, pawn takes pawn, etc., and castling, the champion said the following: ""I have purposely omitted three of the maneuvers in chess, which to the beginner are somewhat difficult to grasp. They are pawn promotion-when a pawn reaches the eight rank it ceases to be a pawn but may but it may be converted to any piece on the board and assumes its function at once. It is thus theoretically possible to have as many as nine queens on the board at once, and so on down the line." The champion then went to explain the castling on the king and queen side and emphasized the importance of moving the king first. The act of pawn takes pawn "en passant" was then thoroughly explained and the actual game started with the champion giving odds of queen to Mr. "X," who proved to be a very apt pupil! Mr. "X" lost the first game in short order-walking boldly into a mating net. In the second game he gave the champion quite the battle and won the approbation of that was worthy. In the third game, the champion managed to trap Mr. "X's" queen but had to give up two pieces for it and saw that he had a lost game but continued on in the hope that his experienced opponent would make some mistake. When the game has reached the position in the diagram the champion was dumbfounded to hear Mr. "X" announce mate in three moves. "Impossible!" exclaimed the champion. "You should win, of course, but mate in three cant be done." "Well, if you have interpreted the move and rules correctly, I am certain I see a mate in three," said Mr. "X." "Of course I have interpreted the rules correctly, exclaimed the now irate champion: and I will lay you a wager of dinner for the members of the club that you fail to mate in three moves." "Done!" cried Mr. "X." By this time nearly every member in the club was watching the game with interest. Now, who won this wager? It will be shown in the solution April 11."
11/4/1937-https://www.newspapers.com/clip/25408721/chess-by-herman-steiner/
"SOLUTION TO PROBLEM 760 by N. Nelson: "April Fool Joke."
White: K. on K1 R. on Q7, and KR1: Kt. on KB7 and KB8: B, on QB5: P. on K7, KKt5, and KKt2, Black: K. on KKt2: R. on KKt1: Kt. on K1: B. on KKt8: P. on KR4. (Wh. 9: BL. 5.)
Many members of the club were very fine players and felt their champion would win. Curiously, most of them were pulling for Mr. "X," as the champion was somewhat of a braggard and if he won they felt they would be hearing about it for a long time. They were, therefore, keenly alert when Mr. "X" started to proceed the game. "My first move is pawn takes en passant," said the smiling Mr. "x." "Of course, I anticipated that move," replied the champion, "and I shall meet it with king takes knight." Oh well then I shall make for my second move, castle: taking the bishop," continued Mr. "X." "This move is according to your definition of castling, perfectly legitimate, as the king moves first, and the bishop being on the knight square, certainly is subject to capture." "Well," replied the champion, "I must say your interpretation is far fetched, but I will grant you even this point as I fail to see how you mate on the next move: you evidently overlook the fact that when you promote the pawn the king will be able to capture it. Of course, I am forced to interpose my knight and it is pinned, but the king will still be able to take care of that promoted pawn. " Well," smiled Mr. "X," "I shall, however, mate you by pawn to king eight, discovering check, as I shall claim a black knight for the promoted pawn, which, according to your interpretation of pawn promotion, is perfectly legitimate. You stated I might choose any piece on the board and, of course, as the black knight is the only piece that will mate, I naturally selected it."
Exit champion.
We are publishing the best solution sent in my Ladderite L. A. Post, incidentally only two others solved this April Fool Problem.
Problem 760 to complete the tale that Mr. Nelson started to what I believe to be the logical solution according to the rules given by the local champion.
1. White: Pawn takes pawn "en passant" check.
The local champion then captured the white knight reposing on his "bishop two."
1. Black: king takes knight.
"Now," continued Mr. "X" "I understand to quote you, the king moves firstl in castling."
"That is correct," agreed the champion.
Thereupon Mr. "X" executed the move in the prescribed manner by first moving his king to his king knight square and removing the champion's bishop and then setting his rook down on his king bishop square calling check.
The champion was nonplussed, for in stating the rules for "castling" he had failed to forsee a circumstance of this kind. He was forced to admit that, according to his own statement, such a move was possible But seeing in spite of this that it was still impossible to checkmate on the next move, he conceded the point and interposed his knight.
2. Black: Knight to king bishop three.
"Did you not say," resumed Mr. "X," "that in 'pawn promotion' you could reclaim to any piece on the board?"
"That is correct," conceded the champion, "but since you insist on taking me literally I might add that there is no "queen' on the board you may claim in one."
"In that case," stated Mr. "X," "I will be equally generous and present you with a 'knight.'"Whereupon Mr. "X" removed the pawn at king seven and placed a black 'knight' at king eight discovering checkmate to the champion's "king."
"Such a thing is impossible !" cried the outraged champion.
"Not at all," replied Mr. "X," "for according to your statement that "upon reaching the eight rank a pawn be converted to any piece on the board and assumes its function at once.'"
To this the other members agreed. So the champion held a dinner in honor of Mr. "X," the most apt pupil he had ever taught.
Respectfully yours,

The act of pawn takes pawn "en passant" was then thoroughly explained and the actual game started with the champion giving odds of queen to Mr. "X," who proved to be a very apt pupil! Mr. "X" lost the first game in short order-walking boldly into a mating net. In the second game he gave the champion quite the battle and won the approbation of that was worthy. In the third game, the champion managed to trap Mr. "X's" queen but had to give up two pieces for it and saw that he had a lost game but continued on in the hope that his experienced opponent would make some mistake. When the game has reached the position in the diagram the champion was dumbfounded to hear Mr. "X" announce mate in three moves. "Impossible!" exclaimed the champion. "You should win, of course, but mate in three cant be done." "Well, if you have interpreted the move and rules correctly, I am certain I see a mate in three," said Mr. "X." "Of course I have interpreted the rules correctly, exclaimed the now irate champion: and I will lay you a wager of dinner for the members of the club that you fail to mate in three moves." "Done!" cried Mr. "X." By this time nearly every member in the club was watching the game with interest. Now, who won this wager? It will be shown in the solution April 11."

"SOLUTION TO PROBLEM 760 by N. Nelson: "April Fool Joke."
White: K. on K1 R. on Q7, and KR1: Kt. on KB7 and KB8: B, on QB5: P. on K7, KKt5, and KKt2, Black: K. on KKt2: R. on KKt1: Kt. on K1: B. on KKt8: P. on KR4. (Wh. 9: BL. 5.)
Many members of the club were very fine players and felt their champion would win. Curiously, most of them were pulling for Mr. "X," as the champion was somewhat of a braggard and if he won they felt they would be hearing about it for a long time. They were, therefore, keenly alert when Mr. "X" started to proceed the game. "My first move is pawn takes en passant," said the smiling Mr. "x." "Of course, I anticipated that move," replied the champion, "and I shall meet it with king takes knight." Oh well then I shall make for my second move, castle: taking the bishop," continued Mr. "X." "This move is according to your definition of castling, perfectly legitimate, as the king moves first, and the bishop being on the knight square, certainly is subject to capture." "Well," replied the champion, "I must say your interpretation is far fetched, but I will grant you even this point as I fail to see how you mate on the next move: you evidently overlook the fact that when you promote the pawn the king will be able to capture it. Of course, I am forced to interpose my knight and it is pinned, but the king will still be able to take care of that promoted pawn. " Well," smiled Mr. "X," "I shall, however, mate you by pawn to king eight, discovering check, as I shall claim a black knight for the promoted pawn, which, according to your interpretation of pawn promotion, is perfectly legitimate. You stated I might choose any piece on the board and, of course, as the black knight is the only piece that will mate, I naturally selected it."
Exit champion.
We are publishing the best solution sent in my Ladderite L. A. Post, incidentally only two others solved this April Fool Problem.
Problem 760 to complete the tale that Mr. Nelson started to what I believe to be the logical solution according to the rules given by the local champion.
1. White: Pawn takes pawn "en passant" check.
The local champion then captured the white knight reposing on his "bishop two."
1. Black: king takes knight.
"Now," continued Mr. "X" "I understand to quote you, the king moves firstl in castling."
"That is correct," agreed the champion.
Thereupon Mr. "X" executed the move in the prescribed manner by first moving his king to his king knight square and removing the champion's bishop and then setting his rook down on his king bishop square calling check.
The champion was nonplussed, for in stating the rules for "castling" he had failed to forsee a circumstance of this kind. He was forced to admit that, according to his own statement, such a move was possible But seeing in spite of this that it was still impossible to checkmate on the next move, he conceded the point and interposed his knight.
2. Black: Knight to king bishop three.
"Did you not say," resumed Mr. "X," "that in 'pawn promotion' you could reclaim to any piece on the board?"
"That is correct," conceded the champion, "but since you insist on taking me literally I might add that there is no "queen' on the board you may claim in one."
"In that case," stated Mr. "X," "I will be equally generous and present you with a 'knight.'"Whereupon Mr. "X" removed the pawn at king seven and placed a black 'knight' at king eight discovering checkmate to the champion's "king."
"Such a thing is impossible !" cried the outraged champion.
"Not at all," replied Mr. "X," "for according to your statement that "upon reaching the eight rank a pawn be converted to any piece on the board and assumes its function at once.'"
To this the other members agreed. So the champion held a dinner in honor of Mr. "X," the most apt pupil he had ever taught.

A.Buchanan: Hi Henrik I am guessing it’s a cheatyface Valladao:

No proof for the ep, castling with capture and promotion to black officer (2020-10-02)

Henrik Juel: Even though I ought to stand by my fellow danish author:
This is a most crude 'joke' problem, especially the 'castling' with capture (2020-10-02)
A.Buchanan: It's kind of a running gag: three silly jokettes which do combine relatively harmoniously (2020-10-02)
A.Buchanan: 1. ... Kf6 allows a short mate, robbing White of the Valladao. 4nNbn/3RP1kN/8/6Pp/8/8/8/4K1bR is the best I can find, fixing the problem, and with less material (2020-10-02)
A.Buchanan: I was hoping that someone would spot that I have shifted a unit to h7 - i.e. the e.p. is even more Foolish :-) I claim it "improves" the problem because currently the e.p. *might* be legal :-) If this is too crude for some, then 4nNr1/3RP1k1/6N1/4P1Pp/8/8/8/4K1bR works. Note you need sTg8 to prevent 2. Sh8#, but wSg6 is blocking g-file, so wBg2 is still free to find other duties on e5. (2020-10-03)

"The First Christmas Problem"
By C.P. Carpenter
The majority of chess players, familiar as they are with that form of chess joke called "Christmas Problems," may not know until they have read the following beautiful legend just how and when the custom originated nor, for that matter, may they be certain of it then, so cursed is this romantic age with belief.
In the Palace of the World, under the pagan line for December 25, was held the great feast of Brumalia. Upon an occasion of this festival, in the reign of the great King Eshamat, that monarch, his guests and vezers were assembled in the readiness for the festival and whilling away the interval at chess when a regged fakir approached the palace gates and craved admission from Elkanoj Bey, the sentry. That official surveyed him grimly.
"Have you got a card?" he asked with elaborate politness.
"I am a poor man, your excellency," replied the fak. "and the only card I ever had was the two-spot out of my pinochle deck,, but I am fearfully keen for my lunch and no harm, but only good. shall come to you see if you allow me to enter. I swear it as Allah sees it."
"Better beat it while Allah still see you." replied the sentry wearily. "He won't be able to see you if you stick around here long."
"I have traveled far, Effendi," replied the fakir, "and am weary. If the king phrase. I may be able to show him a wonderful play at chess. If he cannot solve it perhaps he may reward his slave with a seat at the banquet."
"In that case." said the sentry,"enter, and be your own usher. If you can get away with it, peace o you: and if noy peace to you."
Now the king fancied himself as a solver. and the fakir was well recieved when he had made known his mission.
"Know. Oh. King," said the fakir. as he set up the pieces, "that this position occured in a game between the great King Mahmud and my friend. Ali Bi, who had the white pieces, and it ran into this puzzling position with white to play, andd though it appears impossbile, netherless my friend Ali Bi did may and win this with one move. Now if his gracious majesty csn tell me how. I forfeit my lucnh: if not, I kick in at the festal board. Is it a bet?"
"You are somewhat shy on collateral,"" replied the kin: "netherless we will at least call it a bargain."

White to play and win
Long time did King Eshamat pore over the position without avail, while his company shifted about uneasily and the head cook cursed softly, but fluently in his mother tongue. Finally the king arose with a grunt of disgust.
"I pass," he said. 'What's the answer?"
'It was not in the bargain, your majesty," replied the fakir, "thay I should tell. only that your majesty should fail to find."
"Netherless?" said the king, "since we cannot solve, the problem it is our privlege to look in the appendix for answer. Selim, bring an ax."
"Pardon your majesty," cried the faki. "I will explain the mystery."
"I should be charmed," said the king drily. "What was the movr?"
"My friend Ali BI," replied the fakir, "pushed the pawm."
"But what did he call for?"
"He called for a drink but it didn't come," said the fakir, with a smile which didn't fit his face. "I hope it doesn't happen again."
"Quick fool." cried the kinh. "What piece did you call fo>"
"A queen, your majesty"
"But that woulld give stalemate."
"Even so, your majesty, "but it is also won. My frien, Ali Bi, is a weaker player and King Mahmad graciously offered odds of a draw."
King Eshamat sank into a chair and gezed at the faker. He shook himself, unable to rouse. He shook himslef again, but failed to fill. The fakir moistened his lips and glanced at the feast.
'You bargain, your majesty," he suggested timidly.
"True." said he king. "Salim, find this fakir a place at the feast."
"Very good, yout majesty," said the servant, "but the places are full. Where would it please your majesty I should put him/"
'Ah," said the king grimly, "just crack his skull and put him with the rest of the nuts."

James Malcom: In my view, since this has a story about a majesty, and give the board state, that 1. g8=K! would be a far better solution as I thought before I stumbled upon the source today. Sygyzy declares this a draw, even if -bPh2. =Q/R is stale, and =B/S+ is too weak and Black can fortress. =P does nothing of course, so king promotion is just right here it was for Goldilocks. (2020-10-17)
A.Buchanan: Thanks for typing this in, James, although I don’t really understand the joke. And if 1. g8=K how does Wh dislodge bK from g6/h6? (2020-10-18)
Henrik Juel: The joke seems to be that Black has agreed to accept stalemate as a win for White
If we disregard this, I agree that White cannot win with an extra king; it is easy to dislodge black king from g6/h6, but later White cannot dislodge him from g8/h8 (2020-10-18)
A.Buchanan: If the convention is dynasty, then promotion to a king turns both wKs into erlkings until one is captured. I think these can mate bK, no? (2020-10-19)

Is this the second oldest known Valladao after the 1867 P1360420 found by Keym?
The mainline should be C+, with the "legitimate" ep key, but with many dualed sidelines. (2020-10-14)

"OFFICER HE IS IN AGAIN"
A few weeks ago we publishd a problem by the late Russian master, Tchigorin, in which, owing to the wording of the rule at the time covering promotion, white played 1-P-Kt8 (black knight) and mate. Now one of the leading composers of this country (his name is withheld for his own good) sends us the following position. Try the same key move on this and note carefully the result. The effect cannot but bring a smile. Who was mated first?

Henrik Juel: 1.g8=sS is an illegal self-check (2020-10-15)
A.Buchanan: There’s a implicit notion of atomicity - a move somehow is indivisible. Otherwise one might argue that Bl is checked before the promotion part of the move etc. It’s interesting to peer over the edge once and see the impact of evaluating the game state before the move is finished. This is different from looking at a diagram and seeing that it’s illegal, and realising that a resolution is to think that one is mid-move (2020-10-16)

A.Buchanan: Hi James, couple of nits about old Bosma:
(1) From the 1985 Laws: "Article 5. THE MOVES OF THE PIECES The King (a) Except when cast[l]ing, the king moves to any adjoining square that is not attacked by an opponent's piece." This is separate from Article 9. CHECK 9.1 "The king is In check when the square it occupies is attacked by one or two of the opponent's pieces; in this case the latter is or are said to be "checking the king.' 9.2 Check must be parried by the [move] immediately following." This point may have been an assumption in earlier compositions, as e.g. it prevents kings from being adjacent.
(2) And again from Article 5. "(f) Castling is prevented for the time being - (i) if the king's original square or the square which the king must cross over or that which it is to occupy is attacked by an opponent's piece," Does this prevent your 1.0-0?
What do you think? (2020-11-08)
James Malcom: Ah, why did I but never bother to look at the castling rules!
Well I see nothing against adjacent kings, and seeing about how the "loophole" was about was not explicitly stated couldn't be done, I see it as allowed, and thus what to watch out for in cooks.
The rule on castling says "piece," not pieces. So, quite simply, castling in, out (P1381498), and through (P1381499) check is allowed in my view. (2020-11-09)
James Malcom: Furthermore, if a king is "attacked," they are in check, plain and simple. So, since a triple check/ attack is not defined as a danger to the king, the king may go to any such square, including the acts of catling and adjacent kings.
Also, going by the law itself, and not the Bosma conditions, the king may be captured, but it does nothing and that side can never be checkmated, while Bosma Chess itself allows no king capture. But since the effect is the same, allowing for my jokes to be C+ by Winchloe if the program agrees. Maybe try out my castlings in it? (2020-11-09)
James Malcom: And indeed Andrew has tested my castling problems now-all are C+? (2020-11-14)
James Malcom: Typo-!, not ?. (2020-11-14)

A.Buchanan: Nice way to combine an orthodox theme with Bosma castling (2020-11-13)
James Malcom: Thanks, Andrew. Castling with check is the easiest way to achieve it of course, not to mention the flight taking. I'll try out a version without check, here soon. (2020-11-13)

A.Buchanan: @Henrik how should the dual here impact C+ status we assign? What's the general principle we curators should apply, to avoid us having to make subjective judgements? (2021-01-07)
A.Buchanan: My own simple-minded aesthetic says this is a major dual, because one mate achieves no individual expression elsewhere (2021-01-07)
Henrik Juel: The easiest principle is to say that C+ means completely correct: no cooks and no duals
I would permit short mates, because they occur as a result of suboptimal defense, and double threats, if they do not materialize as duals
But it seems fair also to permit minor duals, including promotion mate duals like TD og LD
So I would not label this problem C+ (2021-01-08)
A.Buchanan: Thank you Henrik, for your thoughtful response. A lot is bundled into one bit of information: the value of the C+? flag. I went back to the Codex to learn more. I think C+ should mean (1) it's been tested & (2) it is sound. Sound (which we don't have in PDB yet) for an antagonistic problem (i.e. d# or s#) means three things: (1) there is a solution (2) there's no cook & (3) there's a defence which forces the specified number of moves. Legality doesn't impact soundness, and for antagonistic problems, neither do duals.
The Codex says there is a lot of judgement involved in assessing the impact of duals in a d#. "C+?" is a result of computer analysis, and I don't think there should be any curator subjectivity in determining its value. I think the answer is to have "duals" as a new separate field so that your valuable analyses aren't lost in conversation, and people can understand the spectrum of quality. In the end, maybe people will be able to set up in their profile their personal preference for dual tolerance, but that's probably some way ahead. I think there are naturally core fields (like cooked?, legal?, tested?) and derived fields (like sound? C+?, HC+?) whose values depend on the core ones. I've sent some notes to Gerd along these lines to see what he thinks. Any thoughts yourself? (2021-01-08)

A.Buchanan: If one allows promotion to sB (and there seems no reason to disallow it since promotion to pawn, king and foreign units are allowed) then the problem is cooked. There is no universally agreed notion of how a pawn can move if it starts on the first rank. Does it get a double hop, and if so on which rank? But the problem is unsound in any case. (2022-02-10)
James Malcom: That is if, yes. But I don't think this problem ought to be left as is: a demonstration of the levels of absurdity and tomfoolery old rules used to allow. Promotion to a piece of another color and dummies were loopholes, yes, but promotion to a black pawn was never included, not even implicitly. All pawns are pieces, but not all pieces are pawns.

Even when we accept that White may promote to a black officer, the prohibition of putting your own king in check is in effect, so the move is illegal (2021-01-02)
James Malcom: Henrik, that's precisely why it's a joke; they can have numerous meanings. as well.
The solution, on page 47, says this about it: "Both sides being mated simultaneously, the game seems a fair draw."

Solution and comments by the author: 1.Ga8Q! (turning the grasshopper symbol 180 degrees) Zugzwang 1. - Gg1 2.Qa8G#, 1. - Ga7Q 2.Qh1#, 1. - f5 Qh8# - The turning of a unit on its own has not provoked any objection. This problem even gave so much pleasure that it found its way into the FIDE Album (1971-1973); so far, the only joke composition to have done so.

What's that? How can Black castle after moving his K and R? Well you can't *prove* that he moved his K or R, so by the usual problemists' conventions, castling is legal. You just *saw* him play Ke8? Yes, but that was a different problem; Ke8 was the key to a SHM in 3, leading to a position in a SHM in 2, in which the key move happens to be O-O-O.

White waits for Black to move before selecting the promoted unit.
Under this joke, a dummy pawn exists ephemerally, but not via the Dummy Pawn rule.

Changing the cook 1. d8=sL! into a try would be nice, but I think the purpose of black Tb6 is to prevent the defense 1. ... Db3!, so unless I'm missing something, Andrew's suggestion doesn't work. (2022-09-13)

'Schach-Echo' empfiehlt, zum Lösen Hochprozentiges einzusetzen: "... eine lustige Aufgabe, die aber nur am Silvester-Abend richtig gelöst werden kann. Wir geben allen, die sich mit dem Stück befassen wollen, den gut gemeinten Rat, erst in gehobener Stimmung zu versuchen, das Rätsel zu lösen. Mit König Alkohol im Bunde dürfte es am besten gelingen."
SCHRECKE: 1. h8=K! f6 2. Kg7 Kg4 3. Kxh6# - Hinweis: Alkohol schadet der Gesundheit!
Wünsche allen ein gesundes neues Jahr!! (2023-01-02)
Henrik Juel: This problem should be labelled joke, I think (2023-01-02)

A.Buchanan: While it's true that there is no legal last move for Black, does this make the problem a "Retro"? The reasoning is hyper-trivial. Was this intended as a joke? Or is there some context for the composition? If only I knew a Danish person who might have some knowledge of the culture at the time... :) (2021-10-07)
Henrik Juel: Ha-ha, here goes
Knud Hannemann was the best danish composer in his prime, but this is surely a joke
Possibly the try 1.g8=D#?? was intended
Skakbladet 1972 is not available for me, but it might throw some light on the problem (2021-10-07)
