Most of us chess players want to become better club players. Which will lead to better players overall but I think a few series designed on "good" opening ideas that aren't the best would be nice.  For example the Italian Game(Evan's Gambit) or maybe the Bird (f4) opening.   Or for black the Caro-Kahn or Alekhine Defense.

What about white plays the London system?

Another good idea. I like how they added the Benoni now to the list of openings on the Chess Mentor.  I been studying that now, since I am trying to broaden my opening reprotoire instead of just playing KID against all things other than e4.

try them all!  i like the alekhine and bird, personally, especially for blitz.
