I've made a number of mods to my copy of Gnu Chess 3 for the Mac, although
I don't intend to post them, since I'm aware of the (to me inexplicable)
antipathy the gnu folks have for the mac.

In addition to fixing various bugs, I've added a "stoopid" mode, which
makes the program somewhat easier to beat, by adding a larger random 
number to the board evaluations.  This makes the program more fun to play
for complete novices.

More interestingly, I've added an "Opening Book Training" mode, in which
all the follow-up moves which are in the opening book are highlighted
on the board.  I've been using this with various opening book files to
aid in memorizing various openings.

While implementing this, I noticed that the program selects opening
moves regardless of whether the opening sequence has been analyzed as
advantagous for white or black.  MCO rates many openings as being
better for black or white, although I suspect the court is still out
on most of them.  Has anyone done any work in this regard, to improve
the program's opening play?
