Breaking News - 15.06.2026: Another new CS is organized... congrats and many thanks to all eng / book authors! Btw, for anyone interested....here are my created/played latest: GM and 2nd books Where all of the current engine players 3800+ Elo are used to play with them as well And as usual, Ban, Cacique, AdrianOliva, Kara etc on Top..amazing performances, Yes, I'm very impressed by these masters..highlight superb, high-level achievement!  Although my created books are not hand-tuned... some of them performed not bad... Especially impressive points come also by the new incomer Reckless 110626, 2nd. Moreover, both Reckless ones performed: 87% draw ratio- lowest record in the tour! Likely because almost all of the eng players are SF-Based, where Reckless is not... And as a last note; Why KillfishPB is used as main chess engine? Simply due to  Belonging to the strongest ones of 3800+ plus in same time being less Drawish too!
  LX's Final Public Book Champion: Ban - My Congratulations to Mursel Berk!  Note: Exactly the same Ban book ver.  is managed to be Champ in LVI CS too
