That also applies to the Half Duck, which does not have its own Piececlopaedia page where such a link can be found. There is no checkmating applet that can do crooked sliders like the Snake, but the non-lame sub-set FN easily forces checkmate, even on 16x16 boards. Forcing checkmate for a piece that has FR3 moves, such as the Tetrarch, is trivial (even on a quarter infinite board), and probably does not need an applet: the piece alone can drive the bare King to a corner.
I would avoid the use of yy in the move description of the Aviaanca, as this is really an undocumented feature of XBetza, to make recognition of some bent riders in the bracket notation possible as long as the latter is still implemented through pre-processing. It will be abandoned when the bracket notation will be parsed directly. Better use [W?AA].
The Zerdinal has mating potential, and it might be useful to give a link to a pre-programmed checkmating applet for it. (E.g. in the Notes section.)
