@Bn Em: your trick for the Ship with the z is clever, but makes the description even less intuitive. When I made the Tamerlane II diagram this alternative use of z did not exist, though. I am not sure if defining a meaning for z and q without first using an s would be helpful. But, come to think of it, s is a dummy on a diagonal atom, as lF is the two left moves, and rF the two right moves, so together these are a full Ferz. But such a dummy s could be used to define the symmetry breaking as used by following z or q. I guess it would be most useful to define it such that it causes the diagonal atom to be interpreted as an oblique one with the longest leap in the sideway direction (i.e. as sN would have been interpreted). Then the Ship would be FsyafqF.
I have no idea why yafqF does what it does. Without a preceding s or oblique leg it triggers the code for the old Betza meaning, which lays out the entire path for the circular piece, with a special mode flag to indicate it can be terminated at any square along the path. But the preceding leg must utterly confuse it...
