Breaking News - 29.12.2025:Well, the ongoing CS is ended...thanks and my congratulations to all authors!The latest entries (both DON book series) performed incredibly super strong!But not enough points to be Number One..so the private Champion is Biyuya,Where Sultan (means 'King' in Turkish) is managed to be final public Champ!Btw, I read also by Troll: The books don't have Elo ratings. not so true..sinceThe amazing books help with Elo...they take you to be on Everest mountain..And and and it's another madness, who says that it's a lottery who is on Top!Yes being even once at Top place..is not easy, but staying there consistently..Is all what makes you a real 'genius'! I don't know (due to my English is not native) if I explained it well so enough?And as last words, about my current created books, they are non-hand tuned,Exc. Perfect 2024 ctg one..but its almost all lines are up to 8 moves..therefore,I'm satisfied with gained points and fully deserves to be named 'perfect' right?)Meanwhile, for my previous postings about organized competition OpenChess
The Private Book Champion: Biyuya - Congratulations to Angel Morano!The Public Book Champion: Sultan - My Congratulations to Cevdet Sarı!
