I have made an attempt to implement Fischer castling in the Interactive Diagram. There is no special XBetza notation for this; a shuffle game has to be specified with a 'nominal' setup. This setup defines (together with the XBetza normal castling definition) where the king must end up, and what the castling partners are (the corner pieces, which must be of equal type). If such a castling is defined, any shuffle that involves the king will then be restricted to make the king end up between the castling partners, and will activate Fischer castling.

To support the shuffle rules of Capablanca Random Chess I enhanced the Diagram's shuffle feature: An exclamation point before a piece in a shuffle specification now either means that pieces of that type should be equally distributed over square shades, or, when there only is one such piece, that it must remain on the shade it is already on. This way Q and A can be forced on different shades by putting them so in the nominal position, and order an extra shuffle of only Q and A to determine which one goes on which shade. The shuffle specs are thus QA,N!BR!AC!QK.

Initially a Diagram always shows the nominal position; there is no spontaneous shuffle. To shuffle you have to press 'Restart' in the AI control bar.

[Editor's Note: Disabling this diagram to keep it from interfering with the one on the page.]
