The EGT generator in the applet currently can only handle ordinary sliders and leapers, or their compounds. It is blind to subtleties like divergence, lameness or ski-sliding. These can be indicated in the Betza notation, and the Interactive Diagram used for display will highlight the  pseudo-legal moves accordingly, but the EGT will move the pieces as if the corresponding m, c, n or j modifiers were not there at all.

I guess there now is a need to fix that, in order to get correct handling of the ski-slide (XBetza jR) of the CwDA Wyvern.

I had already put such a link in the single-piece version, but it was in an inconspicuous place at the end, usually out of view. I now moved it up to a more conspicuous place (just below the statistics table), where there was a large amount of white space anyway.

I think you are right: the general article logically belongs to the 'puzzles' section. I think the link in the per-piece page should be enough to catch the attention of anyone interested in this sort of thing.

The way it is linked to from the Archbishop page looks fine. One complication occurred to me, though: the statement whether a piece has mating potential can be dependent on board size. This is not the case for an Archbishop, but short-range leapers in general suffer from this. E.g. the fraction of won positions with white to move for King + Gold General vs. King drops from 92.1% on 10x10 to 10.8% on 11x11. We should think a bit of how to handle that. Perhaps by adding a static table in the Notes section of the few Piececlopedia pieces to which it applies.

(Further comments, made during the creation of this tool, can be found in this Subject thread.)

The BN piececlopedia page now has a blurb (in the Notes section) as suggested by H.G., passing the appropriate information to the limited EGT page.  If it looks and works fine, I will try to include similar links in the other Piececlopedia pages.

I currently have this page set as a Piececlopedia page, but that seems somehow unsatisfactory.  It strikes me as best categorized as Reference or Problem/puzzle/1-player, but those are not highly publicized.  Maybe the link from the minimal tool (from Piececlopedia pages) is enough?  Or perhaps a direct link from Topic Index is warranted?
