The first image, which I assume is the solution because the title is 'Reachable chess position with 218 moves for White, published by Petrović in 1964.', has no black king?
Look again. It's at A1. You may be confusing that symbol with a different piece.
Ugh. Sigh, I see it now - I thought that was the white king, because it has quite some white in it.
I will allocate 50% blame to my brain and eyes, and 50% to whoever designed a black king to have so much white in it :P Thanks!
