Un des PNd a pris 1 pièce blanche. pour venir de e7. Donc les PB b, c et d ne peuvent se croiser. Le PBg6 ne peut venir de f5 car il faudrait 2 prises noires! Seule reste le dernier coup blanc 0... c2-c4 Ceci implique que le FNb1 est issue de promtion ! C'est le PNb7, il aurait pris 2 pièces blanches. Les PNg5 et h5 ont pris 2 pièces blanches.

3470 Die Schwalbe 68 04/1981
Ergänze 1 Stein zu einem illegal cluster.
Wie viele Lösungen?
Kamikaze rex inklusive
play all play one stop play next play all
Henrik Juel: In Losing Chess the kings are not royal
In Kamikaze RI each capture removes one white and one black man
So the empty board is legal, and any position with one man (KDTLSP) is illegal
An Illegal Cluster is an illegal position that becomes legal when you remove any one non-king
My guess would be 2x6x64 = 768 or possibly 2x5x64 = 640
Where did I go wrong? (2020-07-12)
Henrik Juel: maybe 768 - 32 = 736
where 32 is the number of ways you can put a pawn on row 1 or 8 (2022-10-13)
A.Buchanan: In an “orthodox” illegal cluster, a pawn couldn’t be on the first or last rank unless it was the only non-king unit. There’s probably no principle to cover this rather dull corner-case KPvK. Ask HG! (2022-10-14)
A.Buchanan: And in orthodoxy, do two adjacent kings constitute an illegal cluster? There are no non-king units to remove, so the condition is vacuously satisfied (2022-10-14)
Henrik Juel: On your last comment, Andrew:
Two adjacent kings do not constitute an IC. The position is illegal, and when you remove any non-king you get the same illegal position (2022-10-14)
A.Buchanan: Define that a box is SAFE if it contains no radioactive objects. So is every empty box safe? Yes! :-) (2022-10-14)

Judge Michel Caillaud: Composer succeeds in making Schnoebelen promotion less obvious, thanks to using 2 phases with 2 switchbacks as motivation. The need of a black tempo is the trick that allows differentiation of the phases (and the Schnoebelen Rook becomes an "anti-Schnoebelen" Rook!). Well done.
Sobrecases: Specific try play:

Keywords: Anti-Pronkin, Beweispartie, Ceriani-Frolkin-Thema, Donati-Thema
SB: "Sehr schwer zu lösen, weil kaum Anhaltspunkte in der Diagrammstellung sichtbar sind. Letztendlich schält sich thematisch ein Donati und ein Anti-Pronkin auf weißer Seite heraus. Als Rätsel ok, thematisch zeigt die folgende Aufgabe, was möglich ist." MRic hingegen: "Der wUW-Th8 verlässt sein UW-Feld, nur um später wieder dorthin zurückzukehren und geschlagen zu werden, wonach letztendlich sein Original-Bruder von h1 seinen Tod rächt und seinen Platz auf dem UW-Feld einnimmt. Das ist wieder ein schönes Stück aus dem Hause Thannheiser - kurz, prägnant und witzig, hat mir sehr gut gefallen!" KHS: "Interessant, wie der wT nach h8 gelangt." TZ: "Hier sind die Spuren des sS und whB noch deutlich zu erkennen, so dass die ersten Züge recht klar sind. Die linke mit der rechten Hälfte dann zu verbinden, hat noch ein wenig Mühe gekostet, da ich es länger mit einem wL auf h8 versucht hatte." JB: "Ein starkes T-Duell mit w 'Vorweg-Phönix-Turm' - noch einmal Ceriani-frolkin." HG: "In Fast-Homebase wird ein geschlagener Donati-Turm durch einen Anti-Pronkin-Turm ersetzt. Dupont möchte das allerdings sogar orthodox inzwischen gern doppelt gesetzt haben. Was bei Schlagschachaufgaben in der Regel den Kunstgenuss trübt, sind die (offenbar unumgänglichen) nichtthematischen Schlagfälle, die erkennbar auch die Konstruktion erleichtern."
