Thanks for the info, Thorsten... I read the relevant articles on your web page to refresh my memory. It really would be worth taking up Chris's strategy again, if only to rattle the status quo of the computer chess world. It's not essential for the resulting program to be the best at the first attempt... it's enough just to prove that there are other ways of writing chess programs, because this would be sufficient to encourage other programmers to work along similar lines.
