Judge Hans Gruber (StrateGems 79/2017, p.158-161): "A great achievement: six queen promotions in a fantastic open position. The white king is mobile, the white pieces capture only twice. Only recently, the first author published a problem featuring seven queen promotions in Ser.S#, but the play in C0571 is much better and deeper."
Anton Baumann: gemäss Diagramm unlösbar: 10.Dd2+ nicht ausführbar!
Möglicherweise fehlt sSc2! Bitte prüfen (2020-03-27)
Mario Richter: Das Diagramm im Preisbericht hat einen wBc2.
Interessanterweise ist das Problem trotz des Co-Autors Kotesovec dort als "C-" markiert - da gibt's also noch was zu testen, Anton ... :-) (2020-03-27)
Vaclav Kotesovec: The position is now correct, but full computer test of this problem is not possible. (2020-08-24)

Judge Maryan Kerhuel (Šachová skladba 122/2014): "Enriched by the theoretical statement about the Madrasi rule applied to e.p. captures, we discover a spectacular cyclical exchange of places by the 3 black pawns which, after promotion to S, return not to their home, but to the neighbour’s home. The scenario is achieved at the cost (unavoidable) of some captures of white pieces."
James Malcom: How is Sg7/g5 not a dualed move order at any point? I suppose I do not understand the words "theoretical statement about the Madrasi rule applied to e.p. captures". (2023-04-16)
Arnold Beine: @James: After 10.g5 this black Pawn is attacked/observed by wPf5 (en passant) and is therefore paralyzed and cannot move. After 11.Sg7 the wPf5 cannot capture the bPg5 any longer, therefore the bPg5 is not observed and can continue his escelsior. No duals, the problem is sound. (2023-04-16)
James Malcom: Ah, I see now; thanks. (2023-04-17)

Triple exact echoes with shift [0,1].

Judge Shankar Ram (StrateGems 97/2022, p. 14-19): "Three long trips by the black King to reach the h-file resulting in three concurrent exact echoes with bK on h2, h3 and h4."

Judge Hans Gruber (Best Problems 105/2023, p.572-576): "This is a miracle! Although the author showed in a number of publications around the year 2000, that hundreds of threefold chameleon echoes exist in problems without twinning, which seriously limits the innovation value of such problems, I consider this problem – with only two echoes – as outstanding. The quality of the moves and the reasons why their order is unique, is fascinating. Why should manoeuvres by the black king and the white queen (!) be unique on an open board, without constraining fairy conditions, and with the need to reach in two solutions two opposing edges of the board? The provision of appropriate hurdles for the grasshoppers is the key feature. The ingenious find is that the move Db1 (played at different moves) constrains the black king to the a-file in the first solution while it offers him the whole board for a virtuoso slalom run in the second solution. A sensational problem in terms of agility, and I do not care that the computer helped to find it. Still, the composer had to discover this gem in an almost infinitely large data base."

Published in the article by Sébastien Luce: "Le charme du Scarabée", Phénix 338/2023, p.13164-13168 with a comment: "Cinq Scarabées au minimum sont nécessaires pour mater un Roi seul. Le S15 est un nouveau quadruple écho étonnant de Václav."

Beetle (scarabée) was invented in 1970 by the French composer Roméo Bédoni. Only WinChloe is able to test such problems (not implemented in Popeye either in Alybadix).
Henrik Juel: From the Schwalbe Märchenschachlexikon
Skarabäus: Ähnlich dem geknickten Grashüpfer, nur macht der Skarabäus hinter dem Sprungbock einen 1:2-Sprung in ähnlicher Richtung wie er auf den Sprungbock hinzieht. Von a1 mit Sprungbock auf d4, erreicht er e6 und f5; von d1 mit Sprungbock auf d4, erreicht er c6 und e6. (2024-01-03)
