The Engine Aggressiveness Score Ratinglist

 

The world's first engine-ratinglist not measuring strength of engines, but engines's style of play !!!

 

"Elo is not the end to the means, playing style is, and Stefan's EAS tool is still the best around to measure aggressiveness." - Ed Schroeder (Computerchess legend, author of Rebel engine and famous chesscomputers (Mephisto MM IV, Polgar, Milano, Risc and many more!)), 2024

 

 

The EAS-Score is calculated by my Engines Aggressiveness Statistics Tool out of the games of the gamebase of the UHO-Top15 Ratinglist (main-site) (120000 played games overall). Download the tool here

Meanwhile, the scoring-system of the EAS-Tool got really complex, click here and read the EAS-Scoring explanation.

Here the EAS-ratinglist and at the right side (for comparison), the engines and their normal ranking in my UHO-Top15 Ratinglist (see main-site).

EAS single statistics Highscores (Top 5 Engines)

 

Mention, all EAS-Stats are percent-values, not absolute numbers. So, a weaker engine (with much fewer wins than (for example) Stockfish), can achieve high EAS-Stats and Highscores, too...
