10 Varianten nach Zügen von 8 Bauern.
Motto: Black Diamond
In 'Les Tours ...' heißt es: "Après J.Keeble and L.A.Cardozo-Braga". Beim Keeble-Problem dürfte es sich um P1020108 handeln.
Auch interessant: Ernst Bönsch, "Schachlehre" (1989), Problem 880, gibt als Autor "Yait" an. Dabei dürfte es sich um eine mißglückte Rück-Transliteration aus einer russischen Quelle handeln.

Breuer: Die erste Darstellung eines direkten Albinos, d.h. der Albino gibt selbst die Matts.
Das Thema ist ohne Schachschlüssel nicht darstellbar!

'The Good Companion Two-Mover' gibt als Quelle an: "3002 G.C., July 9th, 1921", tatsächlich steht das Problem aber auf der Titelseite des G.C. Folder vom August 1921.
Evtl. wurde das Problem auf dem Good Companion Day, Atlantic City, N.J., July 9, 1921, präsentiert, oder es gab anläßlich dieses Ereignisses eine Sonderausgabe?!

'Die Bastion': "Zu vorstehendem Problem, welches erstmalig in der 'Pittsburgh Gazette Times' 1916 erschien, schreibt Dr. E. Birgfeld nachfolgende Geschichte:
"Verbrecherjagd im Wolkenkratzer.
Dem König der Bankräuber ist die Polizei endlich auf den Fersen. Während zwei Patrouillen mit vorgestreckten Brownings die Hehler- u. Stehlerbande in Schach halten, geht die wilde Jagd treppauf, Stockwerk um Stockwerk empor. Immer näher kommt der Häscher, immer atemloser wird der Flüchtling. Da, das rettende Dach! Nun der tollkühne Sprung zum Nachbarhaus. Aber was ist das? Sein eigenes Weib hält ihn wimmernd zurück. Mit unterdrücktem Wutgeschrei reißt er sich los. Zu spät!"

[Edgar Holladay]: The hundreth anniversary of Alain White's birth is March 3 of this year. As a memorial tribute, P.L.Rothenberg ("Chess Review" Problem Editor in the early 1940s) and I present No.84, a previously unpublished revision of one of White's problems (s. P1177158). The sprightly (if unorthodox) key, the general construction (including the useful pinned condition of the pieces on d6 and b5), and the problems's main theme (four distinct promotions of the f2 pawn) are all Alain White's. The present revision removes the diluting effects of an extraneous defense and an unwelcome dual mate in one of the main variations, the result being that the problem's only four mates are now given by a promoted black pawn, a feature perhaps not previously shown in a rendition of this task in a two-move selfmate.
