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!).

Code:

     Program                   Elo    +    -   Games   Score   Av.Op.  Draws

   1 CFish 210208 bmi2       : 3742   11   11  2000    52.7 %   3723   56.0 %
   2 Stockfish 13 bmi2       : 3723    3    3 20000    55.8 %   3682   54.3 %
   3 CorChess 1.3 bmi2       : 3716   10   10  2000    49.0 %   3723   56.4 %
   4 Sugar AI 1.50 bmi2      : 3707   10   10  2000    47.7 %   3723   56.1 %
   5 Eman 6.93 bmi2          : 3706   10   10  2000    47.6 %   3723   55.0 %
   6 Fat Fritz 2 bmi2        : 3695   10   10  2000    46.0 %   3723   54.0 %
   7 Honey 13 bmi2           : 3687   10   10  2000    44.9 %   3723   55.3 %
   8 ShashChess 15.1 bmi2    : 3670   11   11  2000    42.5 %   3723   55.5 %
   9 Raubfisch x44 bmi2      : 3639   11   11  2000    38.2 %   3723   55.4 %
  10 Fat Fritz 2 free        : 3633   11   11  2000    37.5 %   3723   48.6 %
  11 Crystal 3.1 bmi2        : 3623   11   11  2000    36.0 %   3723   51.1 %

Code:

Games        : 20000 (finished)

White Wins   : 8750 (43.8 %)
Black Wins   : 382 (1.9 %)
Draws        : 10868 (54.3 %)

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...
