I invented 12 new chess/gothic variants. chess8294400 etc

[JohnWoe]

I generated 16 opening sets w/ certain rules: https://github.com/SamuraiDangyo/variants

13 are new. As Chess960, Chess18 and chess324 ( -> double Chess18. As kings and rooks are in 0, 5, 7 ... ) are already invented. Well chess921600 is "Double Fischer random". So 12 "new" variants. 3,4GB total. Zipped to a 154MB package.

chess8294400 is the biggest standard chess variant w/ double + any castling rules. 8.2M starting positions.

Some double Gothic variants ( gothic-2x-any10000000 ... ) are capped to 10M as the file would be 500GB+.
Castling "any" means. No castling + castling. No means no castling allowed.
Double means both sides have randomized positions.
Standard means kings and rooks are in their original places. Other pieces are shuffled.
In all variants bishops are in opposite colors.
