The Fibnif is a `combination chess piece', introduced by
Ralph Betza in 1996. The name comes from fbNF: a Knight (N) that can move forwards and backwards, but
not sidewards, combined with a Ferz.
Movement
The Fibnif can either move one square diagonally, or can make a jump consisting of two squares vertically
and one square horizontally: i.e., from the eight possible jumps a knight can make, the Fibnif can make
four.
Movement diagram
The Fibmog can jump to all the squares marked with a circle.
