p.boxed
  | A new piece appears: the grasshopper (G), jumping over a piece and landing right after.

p.
  Each player begins with eight grasshoppers between the first rank and the
  pawns on the third rank. The grasshopper moves potentially in all
  directions, but needs the help of a piece for its movement :
  it jumps over the first encountered piece (of any color),
  and land on the very next square.
  This square must be either empty or occupied by an enemy piece (which is eaten).
