Hyperspace Chess

This variant was invented by João Pedro Neto, in February 2000.

Rules

1. The FIDE rules apply except in the following:
2. When a piece is not moved to an adjacent square, the moved piece enters in hyperspace (i.e., it is removed from the board) and travels one square per turn until it reaches the destination (and then it is dropped). The intermediate squares can be empty or not, it does not matter (since the piece is travelling in hyperspace).
3. First the player makes the regular move, then the hyperspace moves (i.e., the drop moves).
4. There may be several pieces in hyperspace at the same time, and more than one can be dropped at the same time.
5. If two pieces are dropped at the same time in the same square (or a piece is dropped in a square occupied by a piece of the same color), they both explode and destroy all the immediate neighbours (including diagonals).
6. If a piece is dropped in a square occupied by an enemy piece, this one is captured.
7. The Knight jump takes one turn in hyperspace.
8. A player looses by checkmate or if his King is destroyed by an explosion (if both Kings are destroyed in the same explosion, the game is a draw)

Variant: The hyperspace jumps are optional. This means a faster and less tactical game.
