Henrik Juel: C+ Popeye 4.61 also
Asymmetry, but not very striking because of the proximity to the a-line
Still a very nice problem, which is solvable by hand (2021-02-07)
A.Buchanan: Nice to have an empty board for the nightriders to canter around in unblocked. That they are line pieces makes the uniqueness of the solution even more impressive. Someone must have already done tablebase for this endgame (2021-02-08)
