Rainer Staudte: In feenschach sollte nach 2012 eine Korrektur dieser Aufgabe erschienen sein. Wer kann diese finden? (2022-08-10)
Henrik Juel: Popeye 4.61 with 'opt non 0 1 thr 0' found no flaws (2023-06-12)
Vaclav Kotesovec: Gustav 4.2e (Lösezeit: 25 : 12 : 21 : 12,11 d, Hashtables: 350000 MB). Brute force, but with an error message "NICHT ALLE WEISSEN ZUEGE WURDEN GEPRUEFT" (Gustav has only room for 126 white moves), so not 100% C+, but C+ with high probability. (2024-03-23)
