Thank you, Dr. Bagley-Jones, for a most logical and direct solution. For
my part, I feared that that other blog's inactivity for the last year and
a half might mean it remains only as a monument, and, of course, the author
himself wrote about his own lack of knowledge on the subject in the post
where the pictures are to be seen.
I have for many years relied on this site as a source for good knowledge
about chess variants and expected my chances of getting an informed reply
quickly would be improved as a result of posting my question here. I hope
this community can help me answer this question.
Best wishes---
