Benkö in 'Chess Life': "Surveying this simple position [P1387772] according to the criteria mentioned above [Idea, Originality, Soundness, Economy, Variations, Beauty and Elegance, Difficulty], one may state that the mating picture is not very original and the solution is too obvious as Black wants to stalemate himself on his first move. Thus the Bishop's role is easily apparent. On technical grounds, it was also unfortunate to place the Knight so far away when it could occupy a central square, K5. Even then, it is a better idea to place it on KR2, which would result in a six-mover. The longer the problem, the less critical the variations. In this case, the author seems to have thought otherwise, since he added "no variations!!!"
Let us try to make more significant chances. This would give us the original problem with new thoughts. [P1321690]
Here White has sacrificed an active "hero" which had first played a serious role in the position.
But on developing the sacrificial idea I came to the conclusion that it would be more thematic if I made an effort to sacrifice a Knight which could not give mate despite its proximity- only the more distant Knight can give the mate. Moreover, I tried also to include the Bishop sacrifice."

White schreibt in 'Tasks & Echoes': "Here we have another type of consecutive White piece journeys quite different from the Merry-Go-Rounds ... No. 11 is a well placed example of the Staircase theme, though by no means the earliest in date. The White Queen starts from the ground floor of her house, and goes slowly upstairs to the very top. She then throws herself out of the window to the street below, possibly with a view to suicide; and surprises herself as much as anybody else to find that by so doing she has really succeeded in mating her old enemy, the Black King, who has been kicking his heels on the street corner."

Mario Richter: Die Information über die Urquelle stammt aus der YACPDB (id=67598). Bei meiner eigenen Recherche im entsprechenden Jahrgang des 'Dubuque Chess J.' habe ich das Problem dort aber nicht gefunden. Wer prüft nochmal nach? (2011-12-17)

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

Henrik Juel: White captured nothing, so Black captured a7xb6xc5xd4xc3, cxd, d7xc6 hxg, and did two more pawn captures to explain the pawn inversion on the f-line; as [Lf1] was captured at home, all 10 missing white men are accounted for
White has no possible last move, so he has the move, and the stipulation is really h#2.5
Last move was g7-g5, because this is the only way to give White a previous move (Kg5-h5), so White may start with an ep capture (2022-03-02)
Henrik Juel: HC+ Popeye 4.61 with analysis (2022-03-02)
