I have also come up with a new piece, the Unicorn, which moves as an Advancing Mao-rider. Does anyone know the value of an Advancer? I estimate it to be about 10 or 11, being more than a Queen because it takes 8 pieces to be able to fully defend a piece from it. A Mao is worth about 2.5, I think, so we can apply the 2.5 (Mao) / 3 (Knight) ratio to the Nightrider, which is worth about 5 or 6, to make 10 (a bit less than an Advancer, as it only attacks 4 squares) / 9 * 2.5 /3 * 5.5 = about 5, same as a Rook.
