Die (Loydsche) englische Version der Forderung zielt nicht auf Eindeutigkeit ab: "Find how a stalemate might result in ten moves."

in 'Ruy Lopez' abgedruckt in der Rubrik "Partidas de fantasia"
AB: Not quite unique alas. 4 Dxc7 & 5 h4 can be transposed. (2001-10-17)
Kostas Prentos: Besides the minor transposition, there's another totally different solution:
1.c4 d5 2.Db3 Lf5 3.Dxb7 h5 4.Dxa7 Lh7 5.Dxb8 Ta6 6.h4 Th6 7.Dxc7 f6 8.Dxd8+ Kf7 9.Dxd5+ Kg6 10.De6= with many duals, too (2002-07-03)
AB: Yes, I was referring to uniqueness of proof game to reach the diagram position. KP responds to the task which appears here as the stipulation. (2002-07-07)
Yoav Ben-Zvi: What is the most simple stipulation that makes the solution unique?

My candidate: "Shortest game ending in Stalemate, given that White has not moved a Pawn after his fourth move"

I would add the length of the composer's solution as a courtesy to solvers: "Game in less than 10.0 moves ending in Stalemate, given that White has not moved a Pawn after his fourth move" (2012-08-27)
A.Buchanan: Hi YBZ: the proof game that Kostas gave 5bnr/4p1pb/4Qpkr/7p/7P/2P5/PP1PPPP1/RNB1KBNR has 12 solutions. 1.c3 gives another 12 solutions. And there's 2 solutions for Loyd. Out of these 26 indeed only one has the property that Wh gets all pawn moves out of the way before 4th move. But it's just occurred to me that there's a variant of Loyd which begins 1.c3 and wQ develops via a4 & a5, ending with 5bnr/4p1pq/4Qpkr/7p/7P/2P5/PP1PPPP1/RNB1KBNR this has 15 solutions, and in 6 of these, Wh plays both pawn moves as moves 1 or 2. Similarly if 1.c4. This only differs from Prentos' solution in the occupant of h7. So the suggested stipulation alas wouldn't work. I am pretty sure i have seen a longer version which is sound as a PG. (2020-05-28)
A.Buchanan: See P1004131 for a longer sound PG. (2020-05-28)
Yoav Ben-Zvi: The cook noted above means that a more elaborate secondary condition is needed. My suggestion:
"PG that is shortest to end in Stalemate (less than 10.0 moves) and White plays 2 consecutive captures that are each longer than 2 squares".
An alternative is to accept the transposition:
"PG that is shortest to end in stalemate (less than 10.0 moves) and wPc2 does not move, 2 variants". (2020-06-07)
A.Buchanan: Is it known that there are no h=n.5 (or h=n half-duplex) from the game array for n9? (2022-07-13)
A.Buchanan: I read Loyd’s stipulation more as a hard task for composers than a fair ask of solvers. Loyd was a genius so of course he came up with a great answer. Adding a latter-day secondary condition to give an arbitrary uniqueness is no help to solvers, and has an aesthetic price. I imagine that Loyd’s withering reaction - as he generally favoured conceptual elegance over rigorous dual elimination. Non-unique PGs are a bit old-fashioned, but they still have their place and James Malcom proves a master at their efficient construction. I wish that YBZ was still with us to possibly contest my point, RIP. (2022-07-13)

Loyd (zitiert in 'Sam Loyd and his Chess Problems'): "No. 487 shows the pinning style as introduced in the waiting class of problems. It is one of my favourite two-movers, being a bifurcated theme, where either Queen or Bishop must remove their protection, leaving the other piece paralysed by the discovered pinning of the White Queen.

Loyd's Orgelpfeifen, Version zu P1046523

A.C. White in 'Sam Loyd and his Chess Problems', S.317: "LOYD'S ORGAN PIPES.
I DO not remember who the German critic was who first called Loyd's famous two-move Black interference scheme the Organ Pipes, but it was a very felicitous description. Those four Black pieces have all the dignity and symmetry of an organ standing out against the wall in a large room dotted over with interested Kings and Queens, Bishops and Knights, as stately an audience as ever listened to the new melodies of John Sebastian Bach when he played at the Court of Weimar.
And Loyd's Organ theme sounded a note no previous composer had ever struck. The sixteen year old boy discovered that, by doubling up, as it were, the simple interference which Nowotny had presented three years before, the most complex of all the fundamental two-move themes could be obtained. He presented it first as No. 452 (P1046523); but two years afterwards he lopped off the rather featureless initial move (Boston Gazette, 1859). "It is excellent as a two-move problem" Loyd wrote twenty years later. "The entanglement of the Rooks and Bishops is odd and pleasing; but it was greatly marred by adding the third move, which is a dull and inappropriate sacrifice of a Rook, adding nothing to the merit of an otherwise pretty problem. A unique idea of this kind is always spoiled by any building up of moves or tacking on of variations that draw your attention from the main theme. Some problems should not be difficult; they are admired because they are funny" (Str., p. 35).
For Loyd the Organ Pipes were hardly a theme. They were an "idea" for the interpretation of the general theme of Black interference play. The use of this "idea" by Taverner [vermutlich P1022415] and others appeared to him an infringement of authorship. The problem world on the whole has decided otherwise. The Organ Pipes are distinctly a theme. They are capable of very varied interpretation. Even Loyd himself showed in No. 454 (P1020202) how elaborately they could be worked up. "I give No. 454," he said, "to show how this simple little idea may be elaborated upon; whether judiciously or not,I submit to the judgment of my readers. I will only say that the position is not calculated to fascinate persons with an artistic eye, no matter what the impression may be after having solved it" (Str., p. 69).
To Loyd belongs all the credit of discovering the Organ Pipes but they have now become public property, and the many versions that have appeared (or at least all the meritorious ones, such as the beautiful series constructed by H. W. Bettmann [s. Pxxxxxxx - evtl. in der 'Pittburgh Post Gazette', ca. 1913]) are fully entitled to rank as independent work. No more striking example could be found to illustrate how, through frequent use, an "idea" rises to the dignity of a "theme" (see p. 203).
For those who are interested in the Organ Pipes let me refer to three articles I have written on the theme, two in the 'British Chess Magazine', August, 1909, and May, 1912, and one in the 'Wochenschach', 25th February, 1912. In all of these I tried to show that the true scope for novel presentments of this theme lay in discovering new relative positions for the Black King with respect to his Organ Pipes, and further that these relative positions are mathematically demonstrable and that they form an accurate locus on the board."
und auf S.215 heißt es:
"For only a couple of his problems did Loyd ever get into discussions, but for these he was never weary of arguing. No. 452 (P1046523) and the famous prize-winner of Taverner [vermutlich P1022415] were like red rags to him. He would claim absolute ownership of the Organ Pipe intersection in conversation, or in print, or in writing, by the hour, on the slightest provocation."

Was die Frage nach dem Urheber des Terminus "Organ Pipes" [Orgelpfeifen] angeht, s. auch die Anmerkungen in Steven Dowds ["SBD"] Artikel "Sam Loyd's Organ Pipes and Benko's 45th Anniversary" (https://www.uschess.org/content/view/11701/666). Das dort aufgeführte Argument, daß Frank Janet eher nicht als dessen Schöpfer infrage kommt, da dieser erst nach 1875 geboren wurde, muß aber nicht stimmen, vielleicht war er nur der erste, dem diese optische Parallele auffiel - s. Anmerkung zu P1274795.

Schachhistorisch interessant bleibt es also, herauszufinden, wann, wo und von wem dieser Begriff zuerst verwendet wurde ... (kleine Diskrepanz am Rande: A.C. White war auch Co-Autor von "Simple Two-move Themes" 1924, wo es auf S.150 heißt: "... the double Grimshaw with two adjacent pairs was called the Organ Pipe theme by Loyd."

See also P1400894.
Felber, Volker: Siehe dazu auch gespiegelt unter P1279572 (2013-10-27)
SBD: Pal Benko asked I write an article for his 45th Anniversary on the organ pipes. I don't think I was the perfect candidate, but the result won a small award in the yearly competition for the online journal:

https://www.uschess.org/content/view/11701/666

I dearly hope a real expert writes the definitive modern article on the organ pipes soon. (2013-10-28)

A.C.White: "LOYD lived up to his profession that others were welcome to reproduce and improve his themes better than some writers are wont to do.
There are dozens of instances on record where his problems closely anticipate later work by other composers, but I have seldom found that he made any objection thereto. On the whole I think he had a certain feeling of pride that others should follow in his footsteps twenty or fifty years after him. More than once I have shown him versions by distinguished modern composers, and he would laugh and say: " Has So-and-so really just published that ? Why, I made it when I was eighteen." It is impossible to refer to all these cases in such a book as this. No. 273 is a single striking instance among many, which I discussed at some length in the British Chess Magazine for February, 1910."

A.C. White: "He [Loyd] cared little for the means he used, so long as his results were successful. And, strangely enough, it almost seems as though his results were increasingly successful and all the more artistic when he took the most radical liberties with the conventional theories of composition. ... It is certainly not considered good form to reply to a check by Black with a direct capture. To do so is recognised as crude, obvious and unscientific. But Loyd's genius thought little of theory, giving all its attention to practice. And his results justified his independence. These problems are among his very best. The key of No. 581 is one of the most puzzling in all two-move composition, subtle, artistic and scientific in the highest measure; and the mates blend with it most beautifully."

'Sam Loyd and his chess Problems': "The interception of the line of action of the Black pieces by White leads to some pretty effects, but in general they are less striking than the effects produced by a similar interception by Black. The reason for this doubtless is that when the Blacks interfere with their own pieces they do so against their will, because the enemy has in some way or other lured or forced them into a trap. On the other hand when it is White who interferes with Black, it is usually a case of direct attack combined with malice aforethought. It may be cleverly devised and it may be well hidden, but a theme which depends for its effect mainly on the moves of White's attack can never have the charm or the unexpectedness of one which is developed through the defensive efforts of Black. Take No. 436 It is clear that removing the White Rook threatens 2 Qb1 mate. Black's obvious replies would be 1. ... B x P or 1. ... P x Q. This readily suggests 1. Rc6 to be the key, because in no other way could White give the two necessary diagonal mates (2. QxP mate and 2. PxB=Q mate) which the Black Queen and Rooks are all in position to defeat. A cut-off key of this sort is better disguised in a three-move problem, as the Black defenses that have to be prevented are less easily seen."

Die Hinterstellungskombination, erstmals von Laws dargestellt, wurde von Loyd unter dem Namen "American Indian" populär gemacht. Die vielen überflüssigen Steine hat Loyd aufgestellt, um die Stellung als Partiestellung erscheinen zu lassen und das Lösen zu erschweren.

Loyd in 'Chess Strategy': "The object of a problem, therefore, being to capture and mate the King, we find a peculiar beauty and difficulty in moves that have an adverse tendency. Take for example the question of capturing the King, we find that a move that frees, instead of confining the King, gives a brilliancy and difficulty to the position that could not be obtained through the medium of any other key move. In 406, the King, being already hedged in, it makes a very pretty key move to give him five avenues of escape."

aus "Sam Loyd and his Chess Problems":
"CHARLES XII. AT BENDER."
The most famous of the Fiske-Loyd stories, and probably the best problem tale ever written, is the sketch: Charles XII. at Bender.
It has appeared in print, since the original publication in the Chess Monthly, in March, 1859, in every conceivable form and language.
In the volume of Fiske's Tales are mentioned the translations into Swedish verse, by J. G. Schultz 1868, into Danish 1876, into Italian by M. Monzecchi 1901, and into Icelandic 1901, and certainly other renderings abound. J. A. Miles put the story into English verse in his Chess Gems, 1860. "Much of the interest attaching to the piece," wrote Mr. Fiske in 1901, "is owing to the problems, which form as it were the gist of the narrative. They were suggested by the writer of the sketch to Mr. Samuel Loyd, the most ingenious and brilliant of all problem composers, who was then in his eighteenth year. The three problems were soon forthcoming, composed in a single afternoon."
The story introduces an imaginary incident during the siege of Charles the Twelfth of Sweden by the Turks at Bender in 1713. Charles beguiled this period by means of drills and chess, and used frequently to play with his minister, Christian Albert Grothusen, some of the contests being mentioned by Voltaire. One day while so engaged, the game had advanced to the stage represented in P1030415, and Charles (White) had just announced mate in three. Scarcely had he uttered the words, when a Turkish bullet, shattering the window, dashed the White Knight off the board in fragments. Grothusen started violently, but Charles, with the utmost coolness, begged him to put back the other Knight and work out the mate, observing that it was pretty enough. But another glance at the board made Charles smile: "We do not need the Knight. I can give it to you, and still mate in four!" (P1037289). Who would believe it, he had barely spoken when a second bullet flew across the room, and the Pawn at h2 shared the fate of the Knight. Grothusen turned pale. "You have our good friends the Turks with you," said the King, unconcerned, "it can scarcely be expected that I should contend against such odds; but let me see if I cannot dispense with that unlucky Pawn. I have it!" he shouted, with a tremendous laugh, "I feel great pleasure in informing you that there is undoubtedly a mate in five" (P1159789). Nor would Charles permit Grothusen to leave till he had solved the problem.
It is perhaps not very remarkable that the minister, fearful of a repetition of such chess battles, left the encampment the next day and joined the Swedes, who took sides with the enemy.
In the original three-mover, F. Amelung has pointed out, in the Baltische Schachblätter, 1900 [Heft 7, S. 274], that if the first bullet had destroyed the Rook instead of the Knight, Charles would have had an equal opportunity of showing his analytical powers by announcing a mate in six (P1159308)!

athulin: Actually, this is from the Cleveland Leader tourney, which closed (i.e. with last date for contributions) in Sept. 1876 for US participants. (Report was printed in Cleveland Sunday Morning Voice on 1877-11-18?) It was published under the motto "Just for Fun" as enigma "Tourney Problem 17" in Cleveland Leader on 1876-12-07? [? after dates because cutting book only has hand-written dates, and so risks inaccuracies].

The reference to the Centennial Tourney is incorrect, probably a misinterpretation of the current source reference. (2022-01-04)
Mario Richter: @anders: The reference to the Centennial Tourney comes from 'The Golden Argosy', p. 217:
"Both problems Nos. 291 [Shinkman's P1057647] and 291A [this problem, i.e Loyd's P1030677] were entered in the same tourney, in which Loyd's set won the second prize. ... No. 291A. S. Loyd. second Prize, Centennial ty., 1876-77" (2022-01-04)
SP: I can verify publication date of 7/xii/1876. Cleveland library has
cutting that includes printed date.
The source of the attribution error appears to be the Golden Argosy,
as Mario says. This is repeated by other sources such as Howard. (2023-06-01)

'Sam Loyd and his Chess Problems' ist sich bei der Quelle nicht sicher und gibt an: "Elizabeth Herald, c. 1890?", 'Der Schachzug' gibt an: "'Chess Magazine', 1878". Die 'Philadelphia Times' schreibt: "The following problem by Mr. Samuel Loyd, originally published in the New York 'Evening Telegram' and reprinted in the 'International' ..."

'New York Evening Telegram' (Leiter der Schachrubrik "Castles and Kings": Sam Loyd):
Composers not infrequently get the idea of the trick for a problem by first placing the black king on the board alone and adding the other pieces one at a time as the problem becomes developed during the course of construction. Sometimes the relative positions of the kings will suggest a good theme to build upon. During a recent visit to the New York Chess Club our chess editor was invited to compose an impromptu position for the members to solve, and the placing of the two kings in opposite corners of the board - as shown on the diagram - was given as a theme to work upon. The position of the pieces illustrates the group of solvers in one corner, and the author in another awaiting the arrival of the solution, which, by the way, he will add, wass not so spontaneous as the composing. It is a crude affair, but is thought to give evidence of latent genius which may yet come to the surface. While referring to the placing of the kings, we give our readers another little puzzle in the same line [s. P1364636], which they will find both amusing and instructive ..."

Laut 'Sam Loyd and his ...' "First Prize, Am. Chess and Prob. Association", Set: "A Fair Field and No Favour"

A.C. White: "The key is wonderful. The Queen is withdrawn to a position of apparently small power for the purpose of commanding squares whose importance is not recognised until the full four-move solution is seen. The White Queen is of small use at f8 until the Queen's Knight is manoeuvred to c3. This requires two more moves, so that the mates are revealed suddenly and with an element of surprise."

Loyd: "The Queen moves from a strong position to one that threatens nothing but the leading idea, which would not be hit upon by chance. The pieces are in active play; the mating positions have all to be created, and the variations are in harmony with the theme".

PR Elson, Neill und Reichhelm: "It is a colossal four-mover, and stands out grandly as the best single problem of the tournament, having a wonderfully deep design together with a most finished rendering."

A.C.White: "We have become accustomed to 'tries' being defeated by the trick of a minor Black Pawn Promotion, but a quarter of a century ago the device was a new one and almost all solvers would have been caught by it. Loyd was so successful with it that he tried it once more at the St. Louis meeting of the United States Chess Association in December of the same year (No. 462). There was a time limit of an hour and a half, and all the fourteen competitors failed to discover the trap in that time."

Das Problem erschien schon in 'American Chess Nuts', 1868, deshalb kann Whites Anmerkung über die Entstehungsgeschichte in 'Sam Loyd and his Chess Problems' nicht stimmen: "True line clearance, in the sense in which Healey used it in his famous Bristol problem of 1861 (P1036903), only occurs in one of Loyd's problems. He defined the theme as that of " withdrawing a piece to a remote quarter, out of play, to allow of the bringing forward of another on the same line " (Str., p. 81). The theme is clearly one in two moves, unless we consider thematic (as many people do) an intermediate move between the clearance and the mate similar to that employed by Healey. Loyd first posed his problem as a three-mover also (No. 498, s.P1055458). His introductory moves served to vacate both the squares b6 and c5 in the final line of mate a7-g1, and in a sense they were thematic, though totally different from Healey's. They were not sufficiently meritorious, however, in his own judgment, to be justified at the cost of the two extra Pawns, and he almost immediately republished the problem as a two-mover (No. 499), in which form it has ever since been known.
Several other two-move renderings of the Rook line clearance, which have been republished at various times under Loyd's name (s. z.B. P1277364), though closely akin to No. 499 in execution, are not by Loyd at all, but are later settings by other composers."

s.a. die vierzügige Version P1053814

A.C. White zitiert Loyd:
"No. 188 is one of those positions that frequently arise where it does not look as if it were possible to mate, yet owing to the paucity of attack we would solve it instantly if assured that a mate was there. From its unpromising aspect such a position makes a most excellent starting point to build from. I employed No. 188 to illustrate a story wherein a player retrieved an apparently hopeless game. It is almost too simple to merit the name of a problem, yet by the judicious addition of another move the sacrifice of the Queen makes it very presentable. (s. P1053814)
Other and better examples might readily be found, as judicious problem building furnishes almost an inexhaustible field for composition. Problems of this kind are pretty and agreeable, and are generally favourites with the public. The positions are what we term graceful ones, and the solutions are sufficiently difficult to be instructive, although the entire difficulty is confined to the discovery of the first move" (Str., p. 23).

Anmerkung in 'Sam Loyd and his Chess Problems': "In No. 495, place the Black Rook at e5, remove the other Black Rook and the King's Pawn, and shift the Knight from h6 to g7, and a two-mover (I Re6) results almost identical with a celebrated problem by J.B. of Bridport (Ill. Lond. News, 1863 [gemeint sein könnte P1019654]), which has no apparent thematic connection with the American Indian. Thus do very small changes in problems have great effects, and thus are most two-ers, however widely separated in appearance, really closely interrelated."

A.C. White: "His unsound 3-er, No. 622, is very important historically, in that it was the first attempt ever made to combine three promotion variations from a single Black Pawn. Last year, J. Möller quite independently arrived at a similar version, entirely sound and very beautiful [P1246525]. The only difference was that he placed the Rook at c1, the Queen at d4, and a Knight at f4 instead of the Bishop. His solution is 1. Qd3, involving the same principles as Loyd's did. I mention this to show how near Loyd's genius led him to the ultimate rendering which another discovered fifty-four years later. But Loyd was, for once, too impetuous: " That problem should be killed. It is not in 'Strategy', nor in my collection. I revised it in that little corner problem which gives all the good there is in it [s. P1059071]" (L. 1909). This must remain one of the instances where I disagree with Loyd. His monogram, No. 623 [P1059071], is ingenious enough, but it lacks the complete task feature which made No. 622 a remarkable conception for a youth of seventeen to chance on."

athulin: The prize information is incorrect: A.C.J did not arrange a tourney in 1877 where the letter "D" was allowed, and no "D" competed in the Centennial Letter Tourney in 1877, in which A.C.J. was part.

Actually, the cited source (White's Loyd book, p. 68) states that the tournament was an "Am. Ch. and Pr. Assn" tourney, and cites Scientific American 1877 as source. (2021-09-30)

Loyd in "The Musical World": "We give, this week, two positions taken from actual play, so as to show how necessary problem study is to make the finished chess player; for it is acknowledged by all chess writers, that the study of problems is indispensale to a player before he can learn how to play the termination of his games correctly. ... Problem IX is the termination of a game recently played at the rooms of the Hudson County Chess Club. We are sorry that we cannot give the moves of the game, as it was very pretty. The termination, however, is well worthy of an examination, as it takes very good play to win."
SBD: Cooked, of course in that 2. Sd4 works as well, as well as the dual mate 8. Da4/b3#, although I am certain Loyd would not see these as defects based on the idea he was trying to show. (2012-02-23)
athulin: In Chess Strategy, p. 246 (but not in White?) Loyd expands on the original story:
"... the committee who were pitted against me
abandoned the game as drawn, which I willingly
accepted, telling them, at the same time, that they
had a forced mate in eight moves. After being informed
of the fact they were unable to discover it." (He also modifies the name of
the club to Hudson City Chess Club.) (2022-08-21)
athulin: ... and in Chess Strategy Loyd also states that he was playing the game blindfolded ... (2022-08-21)

A.C.WHite in 'Sam Loyd and his Chess Problems' (p.23): " I think the three-mover of the winning set can hold its own against any other seven-piece miniature that has been composed since, for difficulty, variety of ideas, and general beauty.
Loyd said of it in the Strategy (p.43): "No. 14 was a haphazard, impromptu little fellow that I composed in an instant and entered in the Chess Monthly Tournament, and never appreciated it until it received the first prize, since which time it has become my most famous problem, and is continually referred to as a difficult and beautiful problem that conflicts with all the established views of composition."
And more recently: "No. 14 was an impromptu posed for Paul Morphy, who complimented it highly. It won the Chess Monthly prize, and has been a popular favourite for many years as showing four different styles of composition in the variations: the brilliant Queen sacrifice, the strategic play with Knight, the waiting principle, and the long flights of the Rook" (MS.).
One of the things Loyd showed me the last time I saw him (p.135) was this very position. "You remember this," he said, setting it up.
"Now look here," and he moved the White King to b6, the Queen to c5, the Black King to f1, the Bishop's Pawn to h4, and added Black Pawns at d5 and e7. "What do you make of this? Why, it is evidently a four-mover. 1. Qc2 Kg2, and you have my problem. There are variations if the King moves to e1 or g1. Now, a German composer published this under his own name and never said 'by your leave.' He objected to a check on the first move, probably, but he has spoiled the whole thing by putting that Pawn at h4. It prevents the best variation of all in my problem: 1. Sg4+ Kh3; 2. Sh2; while he simply repeats the Queen sacrifice. The only merit of the four-mover is that my key, 1. Sg4, still makes a very fair try, though of course, 1. ... Pd4 would defeat it."

Set-Motto: "One of the Press Gang" 3. Turnier der 'Detroit Freee Press'

Loyd: "Key-moves, which from their unexpected nature have a sufficiently startling appearance to be classed among what I have termed surprise moves, have been introduced into thousands of problems and in every conceivable style and shape. I was more particularly referring, however, to the positions of this class wherein the oddity of the move consists in withdrawing the key-piece to an isolated and apparently useless post (Str., p. 104)."
" The idea, however, of introducing the most improbable lines has become so well understood, that our solvers are very apt to search for the most unlikely moves and so overlook the score of plausible traps which the author flatters himself he has set for the unwary. I showed No. 426 to half-a-dozen solvers, every one of whom made the key-move as if by instinct, admitting that they did not see the object of it. I have known many instances where most difficult problems were published, and solved by many, and years afterwards it was found that some simple solutions had been entirely overlooked. Problemists should remember, therefore, that it does not always make a problem difficult to have a dozen very tempting and obvious lines of attack. The fact of their being apparent is a sufficient indication to the solver that he need not look at them; so he passes over awscore of easy moves, and at once hits upon the correct one, which may be the only difficult and unpromising looking move on the board " (Str., p. 207)."

White: "The unexpected ambuscade of No. 426 reminds one of the close of a well-known four-mover by Philip Klett. [Pxxxxxxx]" || Zu den Lösern, die aus der Stellung sofort den Schlüsselzug erraten können, heißt es an anderer Stelle in 'Sam Loyd ad his ...' (S.391) "The practised solver relies upon his own ingenuity; by examining the peculiar position and bearing of the pieces, he soon finds out why they were so placed, and what particular part each piece has to perform to assist in effecting the mate, and thus he discovers the theme or trick of the position. We remember, one evening, last winter, showing a problem to Mr. Cook, who, merely glancing at the board, made the correct move, saying: ' The position of the pieces shows this to be the move, but I cannot yet imagine what it is done for!'" This remark of Mr. Cook was evidently the germ of Loyd's later anecdote about No. 426 ... [s.o.]"

Loyd: 368 was a little bagatelle I posed in the shape of an arrow,
and sent to a friend, who, from the nature of the solution, christened it 'Peek a Bo', and has shown it for years as the most funny problem he ever saw. My friend used to bet that no one could solve this problem without taking back a move".

'Da Schwarz den letzten Zug gethan hat, seine Bauern aber noch auf ihren ursprünglichen Feldern stehen, so muss er Thurm oder König gezogen haben, er hat zwar noch nicht rochirt, darf aber nicht mehr rochiren. Die sich dann leicht ergebende Lösung ist 1) Da6-a3 beliebig 2) D#.'.

Matt in 2 oder 3 Zügen?
Der letzte Zug war nicht g4xh3, weil nur ein weißer Stein fehlt.
Mit vorhergehendem Spiel ist nur eine der Rochaden zulässig, die andere nicht:
Falls 0-0-0 unzulässig ist: 1. Dxg7! Th7 2. Dg8#
Falls 0-0 unzulässig ist: 1. Da3! Txa3 2. Tb8#

Ohne vorhergehendes Spiel sind beide Rochaden zulässig.

In Loyds Aufgabe (P0001946) löst nicht nur 1. Tg1, sondern auch 1. Sh7. Alain C. White schreibt in seinem Buch „Sam Loyd and his chess problems” (S.61), dass Loyd einige Male vergebens versuchte, seine Aufgabe zu korrigieren. Dies gelang Erich Zepler 1926 nach mehreren Versuchen, siehe Wilhelm Maßmanns Übersetzung „Sam Loyd und seine Schachaufgaben“ S.471.
Werner Keym gelang 1972 eine Darstellung (P0000917), in der die Rochaden im Dreizüger und in den Zweizügern ausgeführt werden und sich die Abspiele im Dreizüger von denen in den Zweizügern unterscheiden.

A.Buchanan: Maybe “Organ Pipes” can be a keyword? (2022-04-27)
Henrik Juel: Yes Andrew, it certainly would be an apt description for folks in the know
But it seems that it does not (yet) exist as a keyword (2022-04-27)
A.Buchanan: One might argue against *any* keyword on the basis that one needs to know it already, so I don't quite get your point. Keywords help people to learn terms and their meanings, by seeing a problem they like and then finding what descriptors exist to allow them to find others of the same kind. The phrase "apt description" suggests that I have just invented a metaphor, but it is the actual technical term already. So much so that the example for pattern given in PDB search help is PATTERN='sLa1 sTb1 sTc1 sLd1'. There are 284 such black organpipes and I'm guessing rather less white ones.
Grimshaw of course is there but doesn't even have a definition in English! Please feel free to make sensible definitions for any missing terms, and I am happy to load any into PDB, with auto-translations to the other two of German/French/English. (2022-04-27)
Henrik Juel: As I also commented elsewhere: I am sorry that I was not clear; here is the full story from An ABC of Chess Problems by John Rice, 1970, p.197 (who calls it Organ-pipes)
Organ Pipes is a term coined by Frank Janet, who based it on a problem by Sam Loyd from 1859
It is the formation of black LTTL in which each L interferes with each T and vice versa
Usually these four Grimshaws produce a total of four different mates only, each mate appearing twice (2022-04-28)
Henrik Juel: An ABC of Chess Problems, p.126 defines Grimshaw as follows
A pair of interference variations, in which piece X interferes with piece Y and vice versa
and gives a famous problem by Loshinski as an example with three Grimshaws (2022-04-28)
Henrik Juel: the Loshinsky (PDB spelling) problem is P1017811 (2022-04-28)
A.Buchanan: Yes the Loshinsky is excellent - thanks for sharing. (2022-05-30)

"Problem in honor of E.Lasker"
Der 'New York Recorder' scherzhaft über dem Diagramm: "A few minutes after the Lasker - Gossip game was over (International Chess Congress New York 30.09.1893-17.10.1893) the chess men on their table became strangely disarranged. Gradually they began to take the shape of Emanuel Lasker's initials, and finally a neat two-mover came into existence. It was noticed tha Mr. Loyd was suspiciously hovering around that table. When asked, however, he denied the authorship. But something like a wink of the other eye betrayed him."

Unter dem Diagramm stellt der 'New York Recorder' dann klar: "Mr. Loyd composed the above problem in a very few minutes by special request of and for publication in 'The Recorder'."

Der 'Vorwärts': "Die vorstehende Komposition des anerkannt bedeutendsten Problemkomponistern verbindet mit einem gewöhnlichen Zweizüger (1. Dh3-g3) noch einen besonderen Witz, der durch den Zusatz 'Schwarz hat noch nicht rochiert' bewirkt wird. man überzeugt sich nämlich leicht, daß das Problem unlösbar wäre, falls Schwarz das Recht der Rochade noch zustünde. Man kann aber aus der Stellung selbst den Beweis erbringen, daß Schwarz zwar 'noch nicht rochiert hat', jedoch auch kein Recht (!) mehr hat zu rochieren ... Da Weiß am Zuge ist, ist die Position augenscheinlich durch einen Zug von Schwarz entstanden. Der schwarze Stein, der diesen letzten, zur Position führenden Zug gemacht hatte, befindet sich also noch auf dem Brette. Welcher von den vorhandenen vier schwarzen Steinen mag es gewesen sein. Augenscheinlich nicht einer der Bauern h7 oder g7, die noch auf ihren ursprünglichen Plätzen sich befinden. Zur Entstehung der Position bleibt also nur die Erklärung, daß Schwarz in seinem letzten Zuge entweder seinen König oder seinen Turm gezogen hatte. In beiden Fällen hätte aber Schwarz hiermit das Rochaderecht auch verwirkt. Demnach kann er der Drohung Dg3-c8# auch durch die Rochade (?) nicht mehr entgehen. Derartige Schachkompositionen, die auf einem Wortspiel ('hat noch nicht rochiert') oder sonstigem Witz basieren, nennt man 'Humoresken'."
