I agree with Fezzik! Get Shandorff's book, it is awesome. Don't worry about not being 'high rated' enough to play the lines he recommends. At 1800, you know enough about chess by now to play these sharp variations if you are willing to put in some memory work. Obviously you won't remember everything but neither will most of your opponents so don't worry about it. Just remember that you are allowed to find your own moves at the board, you don't have to follow each opening 20 moves deep before actually playing chess.
That being said, if you are still intimidated, then go for Cox's book. With the words "starting out" in the title it surely isn't for 2000+ players, more like 1600+ I bet. It will give you a complete 1.d4 repertoire too, unlike Shandorff, but of course the depth of analysis probably isn't great. I don't have it but I have heard good things.
Hi. I'm learning the Queen's Gambit (1. d4 and 2. c4) from scratch (I used to play e4 and then I switched to odd sidelines and now I'm learning main lines). I'm around USCF 1800 and I would very much appreciate any recommendations / suggestions.
P.S. I heard about "Playing the Queen's Gambit" by Schandorff but it's for 2200 and above, Averbukh's d4 c4 repertoire is too advanced too, and Cox's Starting out: 1 d4 is for 2000s - 2200s.
