Chess variants I have made (listed on ChessVariants.com)
Backwards Stalemate Chess - This is an April Fools joke. It's normal chess played with the board reversed and some pretending that you aren't playing normal chess. Listed here only because it's on the site.
Chess 4.5 - Chess where one players starts making an opening and the second player then picks the color they would prefer from that position.
Chess480 - This is Chess960 with simplified castling rules (there are also several articles I've written regarding why I think these castling rules are better, but with the popularity of Chess960 it's unlikely to become popular.)
Lao Tzu Chess - Double Chess960 (pieces are not mirrors for Black and White) meets Dark Chess and Crazy House (But you can only drop on spaces you can "see".) This is honestly my favorite.
Simplified Chess - Standard FIDE Chess with seven rules removed. Easier to teach and learn, still has depth of play and a unique feel.
Strate-Go Chess - Chess mixed with Stratego. You can see where pieces are but you don't know what pieces are what. King Capture wins.
Victorian Chess - A variant on Capablanca Chess where all the pawns are protected from the opening and the two strongest pieces are moved to the outside of the board (making the game more appealing to normal chess players.)
I have had major input into Stanley Random Chess, but I'm not at liberty to speak about it.
There are others... but it's a little late so this is a good start.
