Good idea! From 3400 Celo and beyond, balanced openings are the wrong setup.

I downloaded your 195000 balanced games and my EAS-Tool says this.

The Extreme-Beta is especially impressive in the overall length of all won games: 4 moves less (52 instead of 56) than Patricia 5 xtremeEAS and 6 moves less (52 instead of 58) than Patricia 5 and Stockfish 17.1 (!)). That is a huge difference! And the older Rebels (Rebel Extreme (61 moves) and Rebel EAS 2.0 (63 moves)) are much, much worse here. So, a huge improvement here.
But the bad draws stat is still worse than any Patricia and clearly worse than Patricia 5 xtremeEAS. But the good news is, the bad draw stat is improving: Old Rebel EAS 2.0 has 12.33% bad draws, Rebel Extreme has 10.13% bad draws, Rebel Extreme 1.1 has 8.64% bad draws and finally the new Extreme-Beta has 7.39% bad draws. So, the bad draws stat is going into the right direction.

Interesting:

Comparing the Top of my full UHO EAS Ratinglist (UHO openings, different opponents, games not adjudicated) to the EAS-list of the 195000 balanced games (adjudicated games).
I removed the engines, which are not included in the 195000 balanced games from my full EAS ratinglist, then the full EAS ratinglist looks like this

Code: Select all

                         early           bad  avg.win 
Rank  EAS-Score  sacs    sacs   shorts  draws  moves  Engine/player 
---------------------------------------------------------------------------
   1    750655  57.26%  45.49%  44.36%  05.00%   66   Patricia 5 xtremeEAS  
   2    748559  52.40%  42.58%  49.75%  08.28%   65   Rebel Extreme 1.1  
   3    712625  51.61%  43.75%  41.43%  05.49%   66   Patricia 3.1 avx2  
  
   5    653831  50.65%  39.79%  41.13%  07.20%   68   CSTal 2.1 EAS  
   6    643722  50.79%  41.53%  42.61%  05.85%   67   Patricia 5.0 avx512  
  
   8    555597  46.96%  40.00%  34.95%  03.46%   70   Patricia 4.0 avx2  
 
  10    428179  37.88%  38.53%  28.30%  08.79%   75   Rebel Extreme avx2  
  11    381300  32.46%  39.90%  28.36%  09.25%   71   Velvet 8.1.0 risky 
This is exactly the same ranking of these engines as in the EAS-list of the 195000 balanced games. Very remarkable, how reliable the EAS-Tool is, if the number of games is huge. Then, different openings or opponents or adjudication do not distord the results. Good news!

Not so, both are good, both are needed, balanced and UHO.

First 5 engines tested, 75.000 games.

Still 8 engines to go.

Meanwhile it's decided the beta version will be released within a couple of days as Chess System Tal Extreme.
