I do not know.
Maybe the blunder was of the 9 GM's and we need to analyze the relevant games to
know.

Bob Hyatt also said that an IM beated commercial programs with black in that
line.

I believe that kasparov was not ready for that line and I could expect him to
play better later in case of being ready.

He had no prepared lines against it.
If he did an error of going for that line on purpose(I do not know) than the
error is different than preparing the line against commercial programs and he
simply did not believe that the computer is going to sacrifice(possible reasons
may be believing that the computer is already out of book because it used time
for previous move or believeing that the line is bad for computers based on
advice that he got and as a result not believing that deeper blue is going to
play it).
