Remember that Crafty is _also_ an "agressive learner".  It won't repeat
lost openings.

You can always add the command "resign=9" after you enter the "computer"
command.  And then "draw=accept" after that.

Did you try the -xreuse to see if it fixed the problem?  I am going to test
that right now...

There is a problem.  Xboard sends a "new" command after everything is
set up, including the "computer" command from the .craftyrc file.  "new"
restores things to the starting set-up, which is screwed up, of course.

I'll fix "new" so that this doesn't happen, although I am not sure that is
a good overall solution.  Better would be no "new" command for the first
game, which makes no sense anyway...
