It seems highly unlikely that it would be considerably lower than 2821 though. Anand has currently a rating of 2788 and Svidler 2738. Both play usually against the same opponents. So almost anyone concludes Anand is the stronger chess player. Maybe Svidler just had constantly bad luck during his career and is in reality as strong as Anand? Doesn't matter, we don't care. You have to accept some compromise otherwise you will never come to any conclusions. Michael
