This is not necessarily true. History has shown us that white has a 52% to 54%
edge against black's 46% to 48%. While certainly not decisive, it would make
sense in many match situations for a 2600 GM as black to head for a draw against
the 2400 GM with white. It depends on many things; the GM, the match length, the
score, the prizes. Especially against a strong computer this strategy would make
sense because the computer's enormous book would give it an automatic edge in
terms of finding a line that was advantageous to it out of the opening. If you
can head for a relatively safe position, logic would dictate that you do so, as
many of the sharp lines for black have a high loss rate. One loss in a six game
match, and the GM *has* to push hard for a win. Against a computer, this is
deadly, as one of their great strengths is to take any offered material (often
necessary to offer in an absolute-win game), hold it, and win in 50 moves. Also,
since even very good computers *still* do some amazingly stupid things
sometimes, it is a very reasonable strategy to take no risks, and wait for the
box to do something silly, and then crush it like a bug.
