Someone in a previous thread wrote that the surest way to make progress in chess is to identify your weakest area, work on it until you've made progress and then identify your next area. As a diamond member, you have access to ChessMentor and the videos, so why not start working on the King's Indian defense since you have identified it as a weakness. There is a 40 lesson course in CM, and 4 videos that address that very subject. Also Erik has been teasing us for about a month now with his promise of study guides to best utilize the site's resources. Bound to be a great help.
CM helps in memorizing openings, thats not a problem for me, I can handle book moves in caro-kann, French, two knight and even in Indian. The problem is playing after book moves in KID, QID etc.
To answer to my own question, I found this bit more helpful when it comes beyond book moves...
etc.
