I am more the Queen’s Gambit guy. I follow the repertoire by John Bartholomew published in Chessable. Soon another IM will publish there another repertoire based on 1.d4.
For black I will not suggest you a system, but two defences against 1.e4 which are rather interesting, the French and the Petrov.
The advantage of the French is that the ideas are rather straightforward. Usually you know which breaks you have (and what is going on), and most people in your rating don’t have any idea how to play it, as they prepare against 1...e5 and 1...c5. A great book on this defence is Master the French Defence (Chessable).
If you like 1.e4 e5 2. Nf3 you can try the Petrov. It is what Caruana plays and is considered very solid. There is a very book on this defence in Chessable written by a German IM.
Against 1.d4 (or 1.c4 or 1.Nf3 and many other first moves but 1.e4) there are the books written by GM Alex Colovic (Chessable). Great books, but you need a lot of time to learn all this stuff. At your level I would say you should use these books to play correspondence chess and invest your time in tactics. You can begin to learn these books, but this should not be your main priority.
Cheers!
Hello, so I've been trying to get a grasp on the chess openings, but haven't been quite successful yet. I've tried the London System for white, and the Black Lion system for black, in order to try to get a universal opening that can be used against anything that my opponent does, but doesn't seem like this is the right thing to do either, so now I'm wondering if there is like a set of various openings, like 6-7 openings, that together work as a system that would give me a better understanding and foothold in opening-theory?
Or any other resources that would give me a broad and balanced understanding of openings?
I've experimented with Italian Game, Ruy Lopez, London System, Black Lion, and Kings Indian Defense so far.
