Well, bracket notation is currently only implemented for two-leg moves: it tries to reduce those to a commensurate atom, and ignores all later atoms, except their leaper/slider nature for determining if a y should be inserted. So when it works it is basically coincidence.

If you assign a new move to another piece, you can see which XBetza the preprocessor produced from your bracket notation. Which in this case is: RyafufafcfabR . So you see it did understand that the move could end at R, and it did understand there were 4 legs (3 as), it did understand it had to switch from slider to leaper after the first leg. It got a bit confused about the directions, because you added an f where no f was really needed, because that is already default. And you did that after a mode modifier (while I always do directional modifiers first), so that it did not notice it. Hence it adds a redundant f before the u and c. But I don't think that would hurt. It did understand that two continuation legs were f, and the 3rd b.

What it did not understand is that the 4th leg was D. Because it never looked at it, other than classifying it as a leaper, so that it should not toggle back the W to R. So it was close, but no cigar...
