Pawn Structure
I highly recommend the book by Soltis. A good way to go about study is to play out opening variations that you have studied while looking through the different sections of the book to see what themes are important in your favorite openings. I definitely suggest reading through the whole book, though, and not just picking sections that you see commonly. Orejano made a good call with the advice of having an analysis board set up. You should probably do this with every chess book you read, though.
I checked out the wikipedia article. It is pretty good, but kindof just seems like a summary of the Soltis book.
I was wondering if anybody has read the book and if its helpful. I was thinking about getting it but I am not sure, should I?
