And having looked at some of his games over a cup of finest tea - he clearly hasn't mastered 'all the opening moves' either.
But going back to the original question I strongly recommend NOT 'over' studying specific openings at this stage. I am concerned by the focus on some very specific openings in the original post.
Stick to learning opening principles. Of course without knowledge of openings you aren't going to get the chance to show your skills later but at your rating level (and considerably above) you need to know principle not endless theory. The problem with learning openings parrot fashion is you wont understand the tactics / strategy / strengths / weakness of the opening, and wont a) be able to know how to handle an opponent who takes you down a route you haven't learned and b) know how to progress into the middlegame. The best books on openings cover general principles, and link them to the specific opening. Dont get a book full of thousands of lines and try and learn them - a top player will just bamboozle you on move 4 and you will be stuck!
So I agree wholeheartedly with a previous contributor (mad rook). If you want big rating gains learn your tactics (pins, forks, skewers, overload, deflection, interception, decoy, discovered attack...the list is long), and for a cracking 'read in a week' introduction, try 'chess tactics' by Paul Littlewood (Batsford Books).
