The database is made by several parts: mainly we have the games played in private tests, then the machine games ran on matches and tournaments. High quality selected games, most probably the best ones can find on Internet. The database includes a free bonus I use to enrich my book.
Any database was cleaned from clone games (same players + same moves + same date/time) and it was sorted by date in a descending order, so you can find the best games for first.
Each database has a pgn copy for consultation with any chess analysis software.
In the Statistics folder you can find which opening is more used (basing on the ECO codes), the year of play, the average [machine Elo*] and the rate for win/loss/draw.
* = the machine Elo score is DIFFERENT than the human Elo. A 2500 machine Elo engine could have 3600-3700 human Elo score.
