Breaking News - 07.11.2026:Classic (without NNUE assistance) Book CS series are still ON, and and andAs usual, the Champion is again DON DON DON..that's too much..is not?)Honestly, it would be a good idea for Mr. Vasid to wear an 'evil-eye bead'!Other Top books also achieved remarkable performance e.g Kara, Ban etc.Bear in mind that I organized 2 (two) competitions, one by 2700 Elo engine:Alfil 8.1.1(its playing style is close to the strongest human players) ResultsPlus as alternative..the 2nd tourney is played by 2500+ Elo engine Tao 5.6Btw, in 2nd tour exc. DON, plus Queens Gambit.. performed so good too!
