Just like a very old oak it will have a very solid and big base with big main branches made by millions games but the base of the tree trunk won't be so tall. In other words you will have the solidity of an opening book with the best choices for all the openings but the plies will reach only up to the 20th move, since the human mind cannot store a very large amount of variants.

The moves will be weighted and marked by me with the Fritz and Chessbase functions, taking inspirations by othe notorious books and databases, like HiarcsBook and Chessbase MegaDatabase.

The most interesting part is the archive with which I plan to make this book: I will use the largest database I've ever had, with dozens of millions games, everything I can grab from the Internet. 17-05-19 Update: the database has been enriched by all the games played by Lc0 that I could find.


The Oak will be made approximately by:

  • - 10%: > 2500 human players games
  • - 90%: machines games


Format: CTG (Fritz, Chessbase).
