Now you can input and test any fairy condition that popeye supports. Neutral pieces are added too. List of individual fairy pieces is growing, I add them by request.
We are using this new domain for Ankona system (you already know it if you are reading this, of course).
We have added support for (very few) fairy pieces. They can be entered in the “White” and “Black” fields alongside their orthodox counterparts, using their (mostly) popeye codes. More about notation here.
