Point well taken, Peter. I had assumed an 8x8 board. On a larger board I
would expect the Maorider to be stronger than the Knight, but still equal
to the Bishop, which is also stronger than the Knight on a larger board.
As an aside, I think the Moarider (based on the Moa, which moves one
diagonally, then one orthogonally) is worth very slightly more than the
Maorider because it is easier to develop.
