My opening repertoire is currently consisting of:
Open Sicilian (5.Bg5 versus Najdorf, Yugoslav Attack versus Dragon)
Versus 1...e5, Scotch Gambit
Versus 1...e6, Tarrasch Variation: Korchnoi Gambit
Versus 1...c6, Panov-Botvinik Attack (don't know much here)
Versus 1.e4, Sicilian Defence
Versus Anything Else, King's Indian Defence Setup
I have "Playing the King's Indian Defence" by Everyman Chess which I am currently studying back-to-back, and am planning to do the same with some book (not sure which one to get) on the Najdorf just because obviously, these openings are just so complex and have so many critical lines.
For the rest of the openings (Scotch Gambit, Korchnoi Gambit, Panov-Botvinik Attack, various Open Sicilian Lines), can I get by without a book and just research and learn thes line I want to play?
I am in the 1400's USCF.
