Rating systems work perfectly for players who play only in round robin closed events. I think most of them are overrated. Organizers invite same people over and over because they have the same rating and their rating stays high.  -  after winning 1999 FIDE World Championship while ranked # 44 in the world  -  Alexander Khalifman

Just reading about the various opinions concerning the conduct of the recent championship matches convinces me that the only thing to which two chessplayers could agree is that a third one is over-rated.  -  Arpad Elo
