Inaccurate, Van Der Wiel was rated 2558 at the time of the match, and rebel
actually Won 4-2, Shroeder simply gave Charity in the last game, but on the
board Van der Wiel was busted, so if you beat a 2558 Grandmaster 4-2 in a Six
game match that suggest how much of an elo advantage?? For me this was all the
evidence needed.
