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: Mushroom

Historical notes

The mushroom was invented by Ralph Betza in 1996. The original publication of Betza on the Mushroom piece can be found on this website. The code, in Betza's piece notation is: fbNfsLbF.


A mushroom can jump either
  • forwards: one vertical and three horizontal squares; or
  • forwards or backwards: two vertical and one horizontal; or
  • backwards: one square diagonally.

Mushrooms take in the same way as they move without taking.
