The Engine Aggressiveness Score Ratinglist

 

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

 

 

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...
