This playing field is a feature of the Star Trek series. In this variant most pieces, excluding the King, have the ability to "warp" leap to vacant cells on the field.
 
Each player begins with two Attack Platforms denoted by the corresponding colored squares at the center of the shadowy 2x2 grid on the diagram, and retain ownership of these regardless of the pieces which may occupy them. A player may move their Attack Platform, if un-occupied, to any vacant point on the field as a turn. Players are allowed to occupy opposing Attack Platforms.
 
Pieces move accordingly:
PAWNs step without capturing any orthogonal and step with capturing any diagonal on the level or triagonal.
BISHOPs steps triagonal, slides diagonal on the level.
ROOKs slides orthogonal.
KNIGHTs leap one orthogonal then one diagonal.
QUEEN steps triagonal, slides orthogonal or diagonal on the level.
KING steps orthogonal, diagonal on the level or triagonal.
 
All pieces, except for the King, may preform a "warp" leap as a turn. A "warp" leap is preformed to a vacant cell. If the piece is located on a Fixed Level, it may leap to the exact cell of another Fixed Level. If the piece is located on an Attack Platform, it may leap to the exact cell of another Attack Platform regardless of owner.
 
Except for this "warp" leap, all pieces may only change Fixed Levels by way of the Attack Platforms. Knights are permitted to leap to, from and between Attack Platforms but must either pass through or from an Attack Platform to change Fixed Levels. Pawns do not promote.
 
The game is won by check-mating the opponent King.
