I believe the main weakness in the CM8K book is the "missing" learning feature.
Almost all top programs will discover weaknesses or games that they can win in
certain openings and try to repeat these games.  CM8K will lose the same game
over and over again.  I have noticed weak opening lines in all of the top
programs that I own but they eventually stop using them because of the lost
games.
