Hi Oliver,
  Maybe you should voice your opinion to the Grandmasters who played this -
game!  (haha) The analysis was performed by Grandmaster John Emms who is an
authority on the Scandinavian Defence! He missed that good move (8...Ndb4!
against Qxb7 in the 6...Nc6?! line)

 Thanks for the additional input! It just shows that even Grandmasters can make
big mistakes because the game of chess can be so complicated, and we are just
humans trying to play the best we can and that sometimes is not good enough!

Regards,
  Terry
