Der Springerweg im Zug 8-11 und 12-14 ist natürlich dualistisch.

James Malcom: This seems computer testable, excluding the minor duals that there are. (2020-11-18)
Olaf Jenkner: Yes, Gustav gives 65 duals in less than one second. (2020-11-18)
James Malcom: But seeing as how that is part of the intention, clearly, and this is still a widely accepted and reprinted problem, is it C+ with the duals in mind as allowed? (2020-11-19)
SP: Though many problems exist where unsoundness is part of the intention, such as separators in solving tourneys, this is obviously not the case here. Are you seriously suggesting that if Bláthy could show his idea without the duals he would not have done so? (2023-07-10)
Olaf Jenkner: It's an old question what C+ means.
There are promotion duals, triangle manoevres and other stuff what we call "tolerated duals".
In this case I'd think C+ means "computer confirmed the author's intention".
It's different from FIDE rules. (2023-07-10)

Henrik Juel: The late part of the solution is dualistic (2020-08-14)
Joost de Heer: The first dual is already at move 6 (Kb4 or Kc4), so it's not just the late part that's dualistic. (2023-01-30)
