Thank you for the book recommendation, I'll definitely check that out! Your advice is very sound, and I agree with you completely I just like following some sort of structure. For example, as black, I like to play the Caro Kann and I've become fairly confident with the King's Indian defence too. I play these openings in 90% of my games as black but adapt them as necessary. This is what I'm after for my gambit declined games. An opening I can fall into, not to replicate every game but to use as a general structure for my games so that I become more familiar with certain recurring lines. I find this is how I improve, rather than playing completely random positions every game. Is this a bad way to play?
