A resource from Facebook.com, 'Fischer-Random Chess (Chess960/FRC)', crept into the mix. I'll look at that page another time.
Since there's never a better time than the current time, let's go a little deeper. First, I'll repeat that link, Fischer-Random Chess (Chess960/FRC), which leads to a Facebook group. Most of the 'Discussion' posts consist of links to tournaments on Lichess. I found a notable exception at 'AS Mastur shared a link; 9 March  at 16:33':-
- Visualdennis's Blog • My Ultimate Guide to Chess960 (lichess.org).
Written by someone who obviously knows a lot about both chess and chess960, the blog post links to HarryO's 'Chess960 Jungle' blog (also on the right sidebar here) and to this 'Chess960 (FRC)' blog. It also introduced me to two resources that I hadn't seen before:-
- 960 Brilliancies Project (lichess.org)
- Nine-Sixty (netlify.app) 'Guide to 960: Helping you find your way in 960 since today', apparently by the same writer behind the 'Ultimate Guide'.
I'll look at those last two resources another time. Down the rabbit hole once again...
