Radioactive Queen Chess
This variant can clearly explain the abolies of each piece in FIDE, and it's based on FIDE. So it can open new frontiers of chess & its variants.
Setup
Karma strikes black back! White hasn't the queen and light pieces, but on the first move white places unique piece (called Sky Brilliant, Karmium General, Radioactive Queen, Cyberpiece, Superpiece, etc.) on free back rank's square. Black is the first player to move his pieces.
Pieces
All pieces are as in FIDE except for…
Radioactive Queen
She can seem like Amazon (Terror, Maharaja, Khelgi, etc.) but it's much stronger. If Queen is heavy piece, Sky Brilliant is superheavy piece which can:
- as Knight: move & be placed;
- as Bishop: move (as Queen does) & be placed;
- as Queen: move (incl. Pawn, Bishop, Rook, King moves) & be placed;
- as Pawn: move (as Queen does) & take black pawns who moved two spaces by en passant;
- as Rook: move (as Queen does) & allow King's castling to it;
- as King: move (as Queen does), castle to any from Rooks & be one of the opponent's targets.
Castling: black can castle as in FIDE rules. White can castle
- if both his/her pieces (castler & acceptor) hadn't moved yet
- and there's a place between them
even if your King is under check, you can castle to escape, close or capture this piece. Note that you can capture by castling only in case when it's only way to avoid checkmate (if foe piece stands on that square where your acceptor (Rook or Karmium General) will stand after castling) even through this foe piece.
Each piece can castle only once per game (maximum is two castles by white — King-Rook & Cyberpiece-Rook, and one castle by black)
Rules
- Your aim is to checkmate opponent's King.
- If black captures Cyberpiece, white loses in 5 moves after this unless he/she reaches a game result earlier (in this case it ends after black's 5th move, because it can make a draw).
- If white's time is over, it's lose even if black can't checkmate.
Draw occurs if:
- It's stalemate.
- Checkmate isn't available.
- Black's time is over but white can't checkmate.
Notes
Karmium is my created name for 119 element — radioactive alkali metal.
There also will be the variant of
Radioactive Queen Mirror
where all setup, pieces & rules related to white are also related to black (with two versions: Pure RQM and light (but maybe hard for someone) version which also allows one light piece (Bishop or Knight) on any back rank's square to every player).
