It seems that dieter did not prove that score and the score is the score of the
final position after a game of yace against itself.
It is possible that if you try to prove it you get better moves for black.
After 7...dxe5 I get even more than +9 for white but black has alternatives
like 7...Rxg6 +5.98/11 for white and the score may fail low later but I guess
that there are alternatives in earlier moves.
