2021/03/02 Huge CloneWars tournament. Stockfish 13 vs. 10 Stockfish derivatives/clones. 20000 games.
60''+600ms thinking-time, singlethread, i7-8750H 2.6GHz (Hexacore) Notebook, Windows 10 64bit, no ponder, 5 Syzygy bases for cutechess-cli - none for the engines. All engines bmi2-binary.
My Unbalanced Human Openings V2.00 6moves openings were used (low draw-rate and a wider Elo-spreading than classical opening-sets!).
Conclusions: All derivatives/clones are playing measureable weaker than Stockfish 13, except CFish - no surprise, because CFish is running a little bit faster than Stockfish and has no other changes. Mention, that the used Unablanced Human Openings spread the Elo-distances around 2x bigger than a classical opening set...
