I have seen books about: openings, tactics, positional, pawn structure, endgame. Now this topic is another way to look at chess in general. It brings a new way to approach playing chess too.
So please a book or more here if you know about Positional Sacrifice.
Please books about Positional Sacrifice here. In your post name the title, author, and if needed publisher of the book.
In my threads, I follow a pattern, approaching Chess Theory from different point of view. The same holds true here.
I appreciate your inputs beforehand. Regards
