The Piececlopedia is intended as a scholarly reference concerning the history and naming conventions of pieces used in Chess variants. But it is not a set of standards concerning what you must call pieces in newly invented games.

Piececlopedia: BD

Historical notes

The BD is a `combination chess piece', used by Ralph Betza in his Chess with Different Armies.


The BD has the combined movement of the bishop and the dabbabah, i.e., it can move an arbitrary number of unobstructed squares diagonally, or it can jump exactly two squares horizontally or vertically, where the square passed by may be empty or occupied.

Movement diagram

The white circles mark the bishops-wise movement, the green circles those to which the BD can jump.
