And without to not mention this I can't (about testings 3500+ Elo):Via Perfect 2023 book is not required thousands of games (per player)For example, minus plus 800 - 1000 games is enough for determining…Plus it is not required e.g testing each opening as twice… where via weakOpenings are highly suggested thousands games / repeating as twice…
On other hand (via latest Perfect opening book):If NNUE 3700+ tours, it's expecting higher draws, but this is as 'key' thatPerfect 2023 book has no much holes, I mean like NNUE 3700+ engines!Ok… that's all for now… enjoy and happy testings !)
