Of course assuming that you are familiar with this opening...

I think the humans will score much higher with the black pieces.

That is impossible. The human error factor can never be eliminated.

The problem is that computers need to reach a depth of 20-30 plies to be able to
prepare for black's attack. When black's attack is in its initial steps, no
computer will detect a danger. When black's attack is reached the position in
the diagram above, it is too late for computers to put up an effective defense.
