Breaking News - 18.03.2026:     1st of all, I have good news; All of the participated books are available: Download     The Recommended Book Settings (for all) Book Depth: 40 / Best Move: Disabled     Enjoy and Happy testings )     In short, the same vers. of Unofficial VI  are also played by Raubfish (~ 3750 Elo)     Plus a newer Balsa 3750 is entered which is based on Balsa games, av. 3750 Elo,     E.g the other Balsa ver based on av. 3500 elo, now it's clear that v3750 is stronger..     And as usual, if various openings; Perfect, SCCT, Balsa, CEDR... are one of best!     What I can add for less draws, in case of tours via using quality, strong openings?      There are reasonable and logical solutions to reduce the draws, e.g one of them:     Testing different chess engines in strength, such as 3800 Elo vs 3700 Elo etc.etc.     But always forcing the engines with 'terrible' lines is nothing than dead end road!     Plus, the quality starts with strong openings; The corruption with weak openings!     And as last words, sure if you want to fly ;)     Never give up on goals and dreams, because those who give up are only losers !)
     The Leader of Unofficial VII: Perfect X which is based on various Perfect books!
