Grasshopper (chess)
The grasshopper is a fairy chess piece that moves along,, and but only by hopping over another piece. The piece to be hopped may be of either color and any distance away, but the grasshopper must land on the square immediately beyond it in the same direction. If there is no piece to hop over, it cannot move. If the square beyond a piece is occupied by a piece of the opposite color, the grasshopper can capture that piece.
The grasshopper was introduced by T. R. Dawson in 1913 in problems published in the Cheltenham Examiner newspaper. It is one of the most popular fairy pieces used in chess problems.
In this article, the grasshopper is shown as an inverted queen and notated as G.
Movement
In the diagram, the white grasshopper on d4 can move to the squares marked with crosses or capture the black pawn on a7. It cannot move to g4, as there are two pieces to hop over. Black's king is not in check, as in order to attack a piece there must be an in-between piece to hop over.
