Composers: The content demonstrates one Ceriani-Frolkin rook with thematic square c8, two with thematic square e8, as well as the two original rooks both visiting square e8 (anti-Pronkin). It is now generally accepted that only one ‘supporting’ Ceriani-Frolkin is needed while performing two-fold anti-Pronkin theme on the same thematic square. In particular the second Ceriani-Frolkin with thematic square e8 is not involved in de the double anti-Pronkin part of the entry, and hence should be considered as thematic in itself.
This implies that the full thematic content is two anti-Pronkin rooks on the same square e8, as well as two Ceriani-Frolkin rooks on squares c8 and e8, respectively. This very new, difficult and homogeneous combination was our primary intention – it is symbolized, in the future proof game language developed in the special issue Die Schwalbe 250A, by the notation AP(R,R) & CF(R,R).
Concerning the construction, one has to ensure that the thematic captured pieces are the promoted ones and not the original ones (rebirthed after promotion). This is done here with the white g-pawn standing on g7 and the visible promoted Qg6. This couple may be constructed only when the three black captures gxh6, fxg6xh5 have already occured, and rather early in the game, as the above mentioned Queen is necessarily the first black promotion – among the 3 – which left its thematic square. We hope that it is enough to ensure the soundness of the entry.
Concerning computer analysis, this is over for Euclide after 24. Bg2 (Natch may go a bit further but not much) mainly because both programs are considering that after 24. … Rfg3, this rook may arrive to g3 in 2 moves (probably jumping over the white g-pawn!) This obviously could not be considered as a bug, but certainly as a flaw from those programs. The remaining part of our proof game has been checked with Popeye, using the a=b command. (2016-03-25)
Reto: Stelvio finds the solution quite quickly with v1.17 but full resolution would take weeks if not months with the current code. I'll retry this when Stelvio has improved further. (2023-04-17)

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."
