Black Hole Chess
Object: Checkmate the opponent's King.
 
There is no fight for the centre in this variation of chess! Any move that would go to d4/d5/e4/e5 moves the piece from the board. However, it can be re-inserted into the game at any later time.
 
Note that you cannot really move a piece to the centre; you may move it off-board right away if the chance arises.
To reinstate a piece, just click on an off-board piece.
 
The motivation behind the 'black hole' in the centre is to avoid the typical struggle in standard chess to occupy the centre. Furthermore the re-insertion of pieces adds some new excitement to the game.
