I don't think Bob invented parallel search.  He has a working example out there
that people can look at, and he's written a very good paper or two.  He's not
written the only paper on the subject, certainly.  Bob had early access to good
hardware, so he was a pioneer in that regard.

I wrote and debugged my parallel search in a few weeks without more than
glancing at the Crafty source, although I did talk to Bob to ask him how he
handled some cases, and to discuss the problem in general, and I read his paper
and every other paper that's been published in the ICCAJ in the past fifteen
years.

It is a very hard problem, and it's possible to have terrible bugs, but it is
not an earth-shakingly hard problem.
