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 SPCC-ratinglist (main-site) (more than 180000 played games overall). Download the tool here

Meanwhile, the scoring-system of the EAS-Tool got really complex, so please check out the ReadMe-file in the EAS-Tool download, there you find the explanation... 

Here the EAS-ratinglist and at the right side (for comparsion), the engines and their normal ranking in my SPCC-ratinglist (see main-site). Because calculating the EAS-Scores takes a lot of effort, it is possible, that the 2 ratinglists here will not always include the latest updates of my SPCC-ratinglist from the main-site - sorry for that.

 

Latest update: 2022/12/07: Stockfish 15.1

All-time Top10 EAS-Ratinglist

 

This ratinglist contains the 10 engines / engine-versions (later and stronger versions of engines often play less aggressive!) with the highest EAS-score out of my full ratinglist (all tested engines since 2020, except Stockfish Dev-versions). If the same engine would be part of this Top10 list with different versions, the engine-version with the highest EAS-Score is chosen. The full EAS-Ratinglist can be found below the SPCC full-ratinglist - just click here and scroll down...The Elo-numbers were taken from the SPCC full-ratinglist at the time, this Top10 list was updated...

 

Latest update: 2022/11/15: EAS-Tool got a new and better scoring system, so the list had to be re-calculated...

My 2cents: Very interesting is Pedone 3 (not Pedone 3.1, this version plays not so aggressive!), because it is a "complete" engine: Pedone 3 is free, supports multi-threading and multiPV-analysis, includes an Android-version and the strength can be limited (0-100%) (interesting for owners of an electronic chess-board, who need an Android engine with limited strength). Velvet and Uralochka for example do not support MultiPV-analyzing, Rebel and Danasah do not support multithreading. Revenge 1 (successor of Pedone) is commercial and has no android-version.

Additionally, Pedone plays 2x-3x more high-sacs (3-5+ pawns) than all other aggressive engines (but less small sacs (1 pawn, 2 pawns)) - very cool, IMO.
