Isn't the running-leaf by definition stronger than a queen, since the queen is a subset of it? (That is, if the 'degenerate' planar move in which one side of the plane is 1 is an allowable move.)
And I can tell that the young-lion is not allowed to return to its original square (a limitation not shared by the Japanese lion), but there is one slight unclear point: is it allowed to make double captures?
