A chess player's weakness assessed How can I discover my weaknesses in chess and order them from biggest to smallest? I'm guessing a strong GM could analyze a couple of my games and do this for me. But I'm not sure it's worth the economic investment. Is there another way for me to do this?
Made two self-assessment book recommendations to a related question (How to automatically evaluate a player&#39;s performance in a game?). Igor Khmelnitsky's Chess Rating Exam is pretty thorough at evaluating every aspect of your game.

BTW, really like that you are approaching this in a analyzing/organizing your "biggest weaknesses" manner rather than embarking on the fairly commonplace it must be the openings, so I need to study openings knee-jerk/inefficient study plan.
