Threeleaper

A threeleaper or trébuchet is a fairy chess piece that jumps three squares orthogonally (the directions a chess rook can move), leaping over any intermediate piece. Below, it is given the symbol H from Betza notation.
Value.
The threeleaper by itself is not much more powerful than a pawn, but as an additional power to other pieces it is worth about half a knight. Its value as a piece by itself is severely compromised by its being only being able to reach a ninth of the squares on any size of chessboard; combining it with other pieces usually masks this weakness to some extent.
