- Blue move with !? = interesting move you can do
- Blue move with ?! = Dubious move you should avoid

It's important to understand and memorize the difference between !? and ?!.


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

To create this book I used the largest database I've ever had: dozens millions games, everything I can grab from the Internet.


The Oak will be made approximately by:

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


Format: CTG (Fritz, Chessbase).
