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.

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)
