Piececlopedia: Kangaroo (Newton)
Historical notes
The Kangaroo is a piece that combines the movement possibilities of the Knight and Alfil. It was invented by Timothy Newton for his Australian-themed 84-squares contest entry Outback Chess. It should not be confused with another piece of the same name used by problematists but not, as far as I know, in any variant.
Movement
The Kangaroo can either move two squares in one orthogonal direction and then one in the other orthogonal direction, (like a knight), or two squares diagonally (like an Alfil). When moving, the kangaroo jumps, i.e., the move can be completed regardless whether the intervening squares are occupied. By combining a colourswitching and a colourbound move, this piece can return to a cell in an odd number of moves, for example four Knight and one Alfil moves in a lopsided star shape. The relationship between the Alibaba, Carpenter, Kangaroo, and Squirrel is analagous to that between the Queen, Marshal or Chancellor, Cardinal, and Ace or Amazon.
Checkmating
This piece can generally force checkmate against a bare king, with the help of its friendly king, on boards up to 11x11. Try it!
