Fairy chess piece
Fairy chess piece similar to the rook, but it can move at most four squares at once:= ≤ 4
Its value is less than the rook's. It is approximately the same as the bishop's, maybe a little bit more. Using the usual values of the pieces, its value is 3 or 4 points (the bishop is 3 and the rook is 5).
Sufficient mating material in its own (with king).
