|SpaceWarp44 plays as orthodox chess, with the following differences:
Pawns move forward one space diagonally and capture by moving one space forward, "opposite" from the way a standard pawn moves. No initial double move is allowed. Pawns may only promoted to pieces available to be put in play from a standard chess mix. Thus each player may only have one pawn promoted to a queen at any given time.
Bishops may take a single step orthogonally, effectively giving them the movement abilities of both a king and a standard bishop.
Rooks start out upside-down. During the course of the game each rook is allowed a single knight's move. After this special move, the rook is flipped over to indicate that this power is no longer available. Pawns promoted to rooks start out upside-down.
Kings may castle by moving the Rook to the space between the King and Rook, then moving the King to occupy the Rook's starting position.
Location c5, the black square, is not a space. No piece may move through or occupy that location. Pieces are not threatened across it. Exception: The vault of a knight or upside rook may move over c5 and threatens pieces across it.
The 8 shaded squares are warpsquares, divided into 2 subsets, the light colored inner warpsquares and the darker outer warpsquares. A piece on a warpsquare gains further powers in addition to their normal movement and capture abilities. A piece on an inner warpsquare may forego their normal movement and instead move to any outer warpsquare, capturing any occupying enemy piece in the process. Similarly, a piece on an outer warpsquare may move to an inner warpsquare. Pieces may only use this ability to move to a warpsquare of the other type, e.g. a move from an inner warpsquare to another inner warpsquare must utilize a piece's normal movement. A King sitting on a warpsquare is checked if an enemy piece sit on a warpsquare of the opposite type.
