My new openings books

[benstoker]

How do the book makers make their books? What is the general methodology? By hand?!

I would think one could take a large collection of GM games; have your favorite engine then play itself, taking the first 10 moves or so from the GM games one by one, recording the game results; let it play for several days to generate lots of game data; then, let polyglot make a book from the output PGN file, which does its thing by putting high percentages on the most winning opening lines.

Is this the method the book makers use? In any event, is this a sound method?

Around yes. Polyglot system here:
a) GM games, cca last 2 years, cca import 10-15moves
b) correspondence a comp games (length time control and good hw), if good results, import to cca 35 moves
c) merging a-book + b-book

later
d) engine games, for tunning, import cca 10 moves.
e) merging d-book + ab-book
