I'm so happy I stumbled upon this puzzle. This is an absolute masterpiece, so beautiful! Very very well constructed.
I solved it without using the anti-knights constraint by the way. I was at the end of the solve and realizing that I actually never used it. I just completely forgot that it was one of the constraints. Is it known to you that you don't need it?
I'll save my solve path in case you want to discuss it.

Response from Eric: Egubachu, glad you enjoyed the puzzle and congratulations on solving it. Yes, I later learned and worked it out for myself that it is possible to solve without the anti-knight constraint although more difficult. Good job on solving it by using the more difficult route. The puzzle was featured on Cracking the Cryptic a little over a year ago. Thanks for the compliments.
Response from Egubachu: That’s awesome that your puzzle got featured. I’ll try to find the episode. I found this puzzle by clicking on the puzzle portal, that shows a random puzzle. And it didn’t disappoint:)
