atomic
What variant should I make a guide about?
Atomic has too much, do one that no one's every thought of before.
ok then, how about giveaway self capture?

So you want to do one that already exists, right? Cuz I've been making/working on a variant for a long time and just now came to post about it finally and maybe have or ask someone or I mean find someone to make it or who wants to make it or make a guide for it or something, as you said.
I really want to write a guide about some chess variants to help out some people, but I don't know on what variant.
