I uploaded a corrected version of the Spartan Fairy-Max package:
*) It corrects the initial setup.
(Note that this depends on a subtle interplay between the definition
of the initial position in Spartan.fen, the mapping of characters
onto piece bitmaps defined in Spartan.ini, and the mapping of
piece names onto moves in fmax.ini.)
*) I changed Fairy-Max' internal encoding of royalty back to negative
values, as the previous patch eluded some King-Safety tests, leading
to frivolous play with the King (even for white) in the middle-game.
This means the piece value of a capturable King now has to be indicated
in the fmax.ini as the negative of the intended value.
(Downside of this is that the rule that you only win by capturing
the opponent's last royal piece is now always applied, and you cannot
define variants anymore where the loss of the first royal piece
would mean the end. But as I actually don't know such variants,
while there are several 'extinction Chess' variants, this seems
a small price for something good and generally useful.)
