Well, I think you have a pretty good start:
You know what you play with White, You have a Black response against e4, and one against d4. I think those are the cornerstones of any repertoire.
If you wnt to change, do not change more than one of those at once.
Just my opinion.....
As black I am inclining toward Caro-Kann against 1.e4. and against 1.d4 I usually venture d5. I have been playing 1. e4 for white. I am needing a bit of knowledgeable direction in an endeavour to incorporate more strategical position for a stronger game overall rather than just winging it
I really don't have any opening repertoire and am wondering what might fit the bill? One for white and two for black.
What can you suggest? Thanks!
