Glad we agree on that, Drxx. Unclued, try searching for plausible entries (2 words) for 1 across. There’s only one likely letter to fill the second blank and two to fill the sixth. That’s how I stumbled upon the correct context.
I think 1ac might be a deliberate trap (there's an obscure possibility from the other - more obvious - set, but it's well outside the number of 'moves' in between).
I went down that route for quite a while, drxx, and discounted it for the same reason. Also there’s another word in the name, if we are thinking along the same lines.
