Where did you see that?  The only statement I ever saw Joel make was that
when asked how he did against DB while working on the book, he said "it killed
me badly" or something similar.  This was at a press conference in NY during
the second Kasparov match.

I don't think _any_ GM scored 60% against the thing in any match ever played
against it, or deep blue junior...


 Now if you take Joel Benjamin rating and compare it to Gary you will see
