I would like to propose to add a new chess variant to the site. It is quite easy and it is really fun. I call it: "Atomic-x" or "Atomix".
You know, atomic is an explosive variant, cause, taking a piece is like let down a small bomb in the square whre the piece is taken: every piece one square arround disappears (with the exception for pawns).
Well Atomic-X chess is even a more explosive game. It is played with the same rules than Atomic Chess, but with this two additional rules: 1. when a piece is captured, not only disappear the pieces around the taken piece, but also the square in wich one the piece were taken. So, nobody can locate a piece in that square from now on. 2. Once a square has disappear (by some capture on it) no attacks are allowed trougth that square, neither a piece can pass trougth that square; i.e. if white takes Nc8, it will be impossible for black to do long castle (o-o-o), since rock can pass trougth c8 square.
That is all!
I think about this variant cause i used to play atomic chess. Atomic players can find it interesting, i guess.
What do u think about adding this new variant? :-)
