Over the years I manually maintained an opening repertoire in a PGN file (with several "games" per ECO index on average), and now realized I can generate different opening "books" from it - for SCID, CA, or Fritz-based products. The repertoire had been created somewhat ad hoc - based on my games, books I read, engine analysis, database searches, etc. Now - what is the best way to automatically "test" that my book:
- does not miss any very popular responses for one side?
- does not contain any blunders for the other side?
Or is this type of computer checking best done on a pgn file in the first place?
