Outstanding! I've tried out the S and T a bit, and I think it'll simplify a lot of things -- like the Linebacker Pawn's "push" move, to [fhmS-ubcK] and [ifhmT-ubcK] (unless, of course, I should put the u on the first segment; I have a hard time with that bit).

As an aside, I experimented with KY, SY, and TY. The ID only appears to recognize the orthogonal move with those, adding a (2,2) leap so that TY = AX (= (5,2) = Bharal), where I'd expect either AXGY or AXCY* (depending on how one wants to interpret it). I don't know if anything can -- or even needs to -- be done about that.

*AXCY = my Thoroughbred, which would turn the Midnighter -- my second-favorite piece of my own invention -- from NNAX0CY0 to NNTY0.
