A comparison between CCRL and GRL

From - Ratings of chess engines are well established on the known rating lists. Will anything change when we feed engines with only (playable) gambit positions?

With the start of the Gambit Rating List I modeled the ratings to be compatible with CCRL. Now with over 90,000 games played I can make a comparison and conclude it does. Consider:

Code: Select all

   # PLAYER                :  RATING PLAYED  CCRL Gambit
   1 Stockfish 13          :  3667.5  3500   3506  161
   2 Komodo-Dragon 1       :  3581.3  3000   3469  112
   3 Lc0 v27               :  3529.8   800   ----
   4 SlowChess 2.6         :  3421.9  2400   3379   42
   5 RubiChess 2.1         :  3380.5  2900   3338   42
   6 Pedone 3.1            :  3361.7  2900   3334   27

One conclusion is that the top engines profit the most.
