Years: 1886
Vorweggenommen durch P1022354 , s.a. den Artikel im BCM 1886, S.441ff. Dort heißt es: "In justice to Mr. Rowland it must be noted that he undoubtedly can claim priority of publication over Herr Stahl. The Jamaica Gleaner assumed the contrary—in a recent article—upon the strength of a reprint of Mr. Rowland's version by Professor Brownson, but we have personally seen the Dublin Evening Mail of March 4th, and can vouch for the previous appearance of the position there and then.
It is somewhat curious that two of these, no doubt unconscious, reproductions should have occurred to problems crowned or highly commended in the self-same tourney. The Rowland—Stahl case is not quite so startling as the others, although the resemblance is striking enough and, if known in time, might probably have affected the award. ... the slight deviation on move one in these bi-move problems would rather tend to confirm the notion of deliberate piracy, were they the work of authors unknown to fame. We of course entertain no such suspicion and although the name of K. Stahl is almost unknown to us, yet we plainly see the probability that this composer's work was at Buffalo prior to March 4th, as also the utter unlikelihood he could have seen the Dublin Evening Mail of that date. The foregoing expose will undoubtedly not be without its utility, if composers will read aright the two-fold lesson it conveys. Viz :—First. Do not continue to harp upon old themes in a thin disguise. Let "the Bristol" rest in peace, and disturb no more the bones of "the poor Indian" or such used up subjects as the six move flight square two-mover. Second. Only false prophets tell you the future of the problem art points to positions with few pieces and scant variety. On the contrary, that way lies piracy and consequent mortification of spirit!"

Laut "simple Two-move Themes" war das Publikationsdatum allerdings "Jan., 1886"

1.Preis The Wanderer (Milwaukee) 1886; Einsendungsmotto: "Tit for Tat"

[BCM, 1886, S.70]: "The monthly column is an important feature in a new Illustrated Magazine entitled "The Wanderer," published at Milwaukee, price $1 a year, and devoted to the interests of the travelling public. The Chess contents are so thoroughly good in every way that we recommend our readers to write for a copy ..."

[ACM]: "A marked specialty of his work, which will serve as a faithful index of his style, is his constant predilection to elaborate the powers and functions of the pawn. This peculiarity, conjoined with an active use of the white king, can be traced through many of his finest problems. We will venture to illustrate with a few examples, commencing with the first prize winner of the Wanderer tourney, Milwaukee, 1887."

Der gerade geschlagene wSg6 kommt durch die UW wieder aufs Brett und setzt matt; deshalb auch der wSb1.
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)

Mit dem ersten Zug fesselt Weiß den eigenen Sf3. Durch die verschiedenen Deckungen der Drohung hebt Schwarz die Fesselung wieder auf und ermöglicht das Matt.
'ASD': "Der Inhalt der Aufgabe ist hervorragend. Die Figur, die den Sf3 entfesselt, wird gleich mit zum Feldverbau benützt. Das Thema ist schwer zu gestalten und bietet immer neue Reize."

2.Preis im II.Internationalen Arbeiter-Problemturnier, Berlin, 1927 (anläßlich der Osterturniere)

Im Ganzen konkurrierten 72 korrekte Probleme in der Zweizügerabteilung. Fünf Preisrichter gaben ihr Urteil nach Punkten ab. Auf den ersten Preis (s. P1240859) einigten sich fast alle, ebenso hatte der zweite Preis einen erheblichen Vorsprung vor den sonstigen Aufgaben ... Wir glauben, daß der Versuch, mehrere Preisrichter zu selbständigem Urteil nach Punkten, die dann summiert werden, zu berufen, im Großen Ganzen geglückt ist.

Nr. 13 in der 'ASD' doppelt vergeben, korrekt wäre Nr. 14

'VWfS': "7 verschiedene Matts durch Abzug des Ld6 ('Maximaltour')"
'ASD': "Durch den Schlüsselzug wird der Ld6 angegriffen, er muß also ziehen. Aber wohin er auch geht, immer ermöglicht er durch Verstellung, Verbau usw. ein Matt im nächsten Zug. - Dies ist ein Gegenstück zu der sogenannten Maximaltour des schwarzen Springers, nur ist dem wegziehenden schwarzen Läufer alle 13 möglichen Felder zur Verfügung stehen und auf alle Züge ein anderes Matt erfolgt."

The 2018 FIDE laws state: "3.7.2 on its first move the pawn may move as in 3.7.1 or alternatively it may advance two squares along the same file, provided that both squares are unoccupied."

Hence Black's newborn 8th rank pawn, which has never been moved before, reserves the right to commence a double-step on its first move, and likewise White receives the right to capture it en passant as they do with a 7th rank pawn.
Henrik Juel: This un-dummy-pawn is like a pawn created on c8 by the Einstein condition
The retroplay looks wrong, what about 1... d8-d6!? 2.d7-d8=sB!? c6xYb5 (2020-04-30)
James Malcom: That makes much more sense Henrik. I have edited it accordingly. (2020-04-30)
A.Buchanan: You don't like Adrian's (: haha? What about :) then? In heraldic terms, it would be described as "regardant". See 270 on https://www.heraldica.org/cgi-bin/atlas.pl?12. I don't know the word for "non-regardant", which is the default direction for the head, e.g. most of the others on that page.
We could replace wBa6a7 with wSa6, but alas having the 3rd knight is non-thematic & distracting. The other thing I would've liked to do is empty b2 so the promotion is forced to be to D. Such a tiny problem should have precision promotion. Needs more thinking. (2020-05-01)
James Malcom: UPDATE: The position has been edited to have one less piece and a precise queen promotion. (2020-10-12)
A.Buchanan: There is dialogue here which is now orphaned by a change of diagram with new matrix. Suggest we revert to the older diagram and mark it superseded by a new PDB entry here (2020-10-12)
James Malcom: I agree-it is now done. (2020-10-12)

Here's an illegitimate 2-mover for all you illegitimate problem lovers. Submitted by Doug Brown, Moorestown, NJ. Solution below.

(Incidentally, Doug, your mate position on 3 ranks does not need the King. Try again.)

'Aufbau': Das Problem des en-passant-Schlagens ist in unserer Aufgabe nicht die Schwierigkeit, der wir besonderen Wert beimessen, sondern es handelt sich lediglich darum, die Korrektheit der Stellung nachzuweisen, nämlich warum zuletzt nur f7-f5 von Schwarz geschehen sein kann.
f6-f5 oder Sh4-f3 kann nicht geschehen sein, sonst hätte der weisse König im Schach gestanden; die Möglichkeit, dass evtl. ein dritter Springer, in welchen der fehlende weisse Bauer umgewandelt wurde, bei der Placierung des schwarzen Königs auf g3 durch ein Abzugsschach (Sf2-g4 Kg3xg4) ermöglicht haben könnte, fällt fort, da der fehlende Bauer nur ein weisser Läufer geworden sein kann, der jetzt auf c8 steht. Der bei Beginn des Spiels vorhanden gewesene weisse Läufer muss auf seinem Platz geschlagen worden sein, da Be2 und g2 seine Entwicklung verhinderten.

beim Nachdruck im 'Aufbau' wurde die Forderung vergessen, humoristische Korrektur am 28.05.1943: "Wir haben bei der Veröffentlichung des Problems No. 4 geflissentlich unterlassen, die Zahl der Züge die zum Matt führen, anzugeben. Wir wollten unsere Sehachfreunde auf die Probe stellen. Unsere Löser haben diese Intelligenzprüfung glänzend bestanden. Es handelte sich um einen Zweizüger."

Übrigens: Der 'Aufbau' fordert für eigene Probleme (31.03.1944, Schachbriefkasten): "Auf verschiedene Anfragen teilen wir hierdurch mit, dass wir die Weiterveröffentlichung unserer Schachprobleme mit Quellenangabe 'Aufbau' gern gestatten.", nimmt es aber selbst mit Quellenangaben zumindest in der Anfangszeit nicht so genau - wie hier z.B. keine Angabe zur Originalquelle.
