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)
