Three-dimensional chess is a variant of the ancient Earth board game chess.
Movement of pieces is similar to that of traditional chess. The main difference is that in the course of a move, pieces may move up or down any number of levels. According to the Star Fleet Technical Manual, the starting positions of King and Queen pieces are on their own respective attack boards with their own set of Rooks and Pawns. Knights, Bishops and the remaining Pawns occupy the first two ranks of each color's fixed boards. MovesEdit
