Als Quelle wird "Burnley Express" in 'The Chess Problem: Text-Book with Illustrations' angegeben.

Motto: "We cannot all be masters"
SCHRECKE: C+, popeye 4.87 (2022-04-16)
athulin: Tourney source is probably best expressed as 'Burnley Express', as the name changed in the period.

First publication: Burnley Express and Advertiser, i. 173 (1881-03-26), p. 3, prb. 164.

The reference to a reprint in Canadian Chess Problems below seems odd: as far as I can find that problem is a #3 by G. A. Robinson with a quite different position. (https://books.google.se/books?id=bywVAAAAYAAJ&dq=canadian%20chess%20problems&pg=PA140#v=onepage&q&f=true) (2022-09-28)
Mario Richter: Anders is right, Dieter mixed up two sources: the correct reprint source name is not 'Canadian Chess Problems', but 'The Chess Problem. Text-Book with illustrations', p. 157, Problem 140. (Its publication year is usually given as 1886, not 1887).

One general remark: when introducing new sources in the PDB, the information provided should make it possible to identify the source uniquely. That is, names like 'Times', 'Mail', or in this case 'Express' without additions, should be avoided. I know that this is not easy, since in many cases the problem data comes only from secondary sources, where the original source may only be given in rudimentary form (e.g. something like "Our today's problem is taken from 'The Mail'"). Perhaps it would be better in such cases to not introduce a new source but onlyx to make a remark in the comment field of the problem ... (2022-09-28)

SP: Double Berger cutting point. The earliest source known to me

anticipation of Kraemer, D. Schachbl. 1925. However, I cannot
find this anywhere in the 1911 NP column. (2023-11-16)

BS Problemid: 34265
Authors: Grupen, A
Sources:
Years: 1928

TODO: Quelle prüfen - weder bei visueller Prüfung noch im Schwalbe-Index für die Jahre 1928-1930 konnte die Aufgabe gefunden werden.

Das Rätsel ist gelöst: Die Aufgabe erschien nicht in der Schwalbe im Jahr 1928, sondern in einem Sonderheft der Schwalbe am 06.07.1965 als Widmungsaufgabe von AG zum 70. Geburtstag von Dr. Wilhelm Massmann mit der Problemnummer(!) 1928. Den Abdruck dieser Aufgabe fand Carsten Ehlers.

Die Quelldaten in der PDB sind nun richtiggestellt worden.

Gerald Ettl: 4.-Tb5 ist ein völlig uninteressanter Verteidigungszug.
cooked ?? Für mich eine schöne und korrekte Aufgabe. (2017-02-14)
Henrik Juel: I agree completely, Gerald
4.Sc3 threatens 5.Th3, and 4... Tb5? does not prevent the threat, it just delays the mate by one move (2017-02-14)
Henrik Juel: The problem was reprinted in Die Schwalbe to commemorate the author's death a century earlier; here the dual after 4... Tb5 was not mentioned (but the immaterial promotion mate dual was...) (2017-02-14)
Dieter Berlin: Die sog. Verteidigung 4. ... Tb5? wird in keiner Quelle genannt oder moniert.
Einstweilig lösche ich diese, und 'cooked' ebenso. (2022-08-31)
