HBae: Das Probespiel ist dualistisch: 1. Dg3+? Sxg3 2. Kf4,Kg6
In der Originallösung (Schach 1959 Seite 313) wird das Probespiel nicht erwähnt. (2021-05-10)
HBae: Schwarz darf nicht 1. -, Kg2? spielen wegen Kurzmatt spätestens in 6 Zügen:
1.Ke4 Kg2? 2.Tf2+! Kh1! 3.Kf5+ Kg1 4.Tf3 Kh1,Kg2 5.Tf4+ Kg1 6.Dg3+ Sxg3#
1.Ke4 Kg2? 2.Kg3? 3.Tf4+ Kg2 4. Kf5+ Kg1 5. Dg3+ Sxg3#
Damit das Probespiel eindeutig ist, könnte der wTf6 auch auf f7 stehen (C+ Popeye v4.37). (2021-05-11)

Henrik Juel: Popeye 4.61 with 'opt non 0 1' found no flaws (2021-03-14)
Henrik Juel: If you just want to find the solution quickly, this info may be useful:
with 'opt non 0 1' the solution was found in a couple of hours, and the testing completed in 8 hours
with 'opt non 0 1 not' the solution was found in 10 minutes ('not' means nothreat) (2021-03-15)
Olaf Jenkner: If you just want to find the solution quickly, start Gustav using "automatische Parameter". The solution will be shown after 10 seconds. (2021-03-16)
Henrik Juel: Can Gustav test this problem in a reasonable time, Olaf? (2021-03-16)
Olaf Jenkner: Yes, if you are patiently. It will take 5-7 weeks. (2021-03-16)
Henrik Juel: Thanks for the information
One would have to be unreasonably patient to consider that a reasonable time... (2021-03-16)
