First, I _never_ said commercial programmers "steal" things from crafty. How
would you steal something that is given to you?  However, I can likely point
out several ideas from Cray Blitz (and now Crafty) that are in _your_ program
as well as others...

Warped thinking.  Lets play a match using a 16 cpu alpha system.  Since you
are 'ahead' you ought to crush me, right?  I mean, parallel search is not a
creative thing to develop, so you should be able to have one up and going by
tomorrow?  I'll contact DEC.  :)

Your comment says this:  "what I (you) work on is creative. What you (me) works
on is not creative."  I say _horsefeathers_.  Perhaps after you start to work
on a parallel search, and use all the information I and others have published,
you will be able to 'create' exactly what we have done?
