The grasshopper is a fairy chess piece that moves along ranks, files, and diagonals (like a queen) but only by hopping over another piece. The piece to be hopped may be 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 may jump over pieces of either color; the piece being jumped over is unaffected.
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 with notation G.




Movement



In the diagram to the right, the white grasshopper on d4 can move to the squares marked with crosses (b2, d1, d7, and h8) or capture the black pawn on a7. It cannot move to g4, as there are two pieces to hop over.




Example problem



Solution:

1. Gh3 Gh4 2. Gh5 Gh6 3. Gh7 Gh8 4.Ge7 Gd7 5. Gc7 Gb7 6. Ga7+ Ga6 7. Ga5+ Ga4 8. Kc2# (Ga6 9. Gxa1)#




Related pieces


Other related pieces in the problemist tradition are the eagle, hamster, moose, and sparrow, which move and capture like the grasshopper but are deflected (to either side) 90°, 180°, 45°, and 135°, respectively, upon passing the hurdle.

Grasshopper chess is a chess variant, in which the pawns are allowed to promote to a fairy piece, the grasshopper. The grasshopper (shown as an inverted queen) must hop over other pieces in order to move or capture.
In some variations grasshoppers may also be present on the board in the opening position, in addition to the usual pieces. For example, pawns can be moved forward and grasshoppers put along the second and seventh ranks as shown on the diagram at right. Another possibility is to replace queens with grasshoppers in initial position, while pawns can still be promoted to queens. Grasshoppers are capable of moving as a queen but must jump over a piece and land one spot past the piece that they jump. Pawns are not allowed to go twice for their initial move.
