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 170000 played games overall). Download the tools here

 

The tools are searching for sacrifices in games (from 1 pawnunit-sacs up to 5+ pawnunit-sacs) and for won games, which are very short (split into games up to 40/45/50/55/60 moves), but only, if the short game ended before the endgame (a low material check is done!). Because a weaker player can be playing aggressive, too, the EAS-Score (= Engine Aggressivenes Score, see explanation below) and all other statistics are build on percents from the won games of an engine/player. So, if an engine has won more games, it must win more short games or win games with sacrifices. A weaker engine, which has won less games, need less wins of short games or win games with sacrifices.
EAS-Score is: (percent*10) of the percent-values of the sacs (1-5+ pawnunits) calculated out of the won games by the engine, only. Higher pawnunits-sacs give bonus-points:
1 pawnsac = 3x points *** 2 pawnsac = 10x points *** 3 pawnsac = 25x points *** 4 pawnsac = 50x points *** 
5+ pawnsac = 100x points

Additionally, very short won games (percent*10) with or without sacs give bonus-points: 60 moves or less= 3x points *** 55 moves or less= 10x points *** 50 moves or less= 25x points *** 45 moves or less= 50x points *** 40 moves or less= 100x points (but only, if the short game ended before endgame (low material check is done!)).

 

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.
