The authors used the program Crafty and argued that even a lower-ranked program (Elo around 2700) could identify good players. [19] In their follow-up study, they used Rybka 3 to estimate chess player ratings. [20] In 2017, Jean-Marc Alliot compared players using Stockfish 6 with an ELO rating around 3300, well above top human players. [21]
The Elo [a] rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess or esports. It is named after its creator Arpad Elo , a Hungarian-American physics professor.
Stockfish has been one of the best chess engines in the world for several years; [3] [4] [5] it has won all main events of the Top Chess Engine Championship (TCEC) and the Chess.com Computer Chess Championship (CCC) since 2020 and, as of 16 November 2024, is the strongest CPU chess engine in the world with an estimated Elo rating of 3642, in a ...
Though published in 1978, Elo's list did not include five-year averages for later players Bobby Fischer and Anatoly Karpov. It did list January 1978 ratings of 2780 for Fischer and 2725 for Karpov.

Performance rating (abbreviated as Rp) in chess is the level a player performed at in a tournament or match based on the number of games played, their total score in those games, and the Elo ratings of their opponents. It is the Elo rating a player would have if their performance resulted in no net rating change.
This template uses Template:WikidataChart to create a line chart of the Elo ratings of chess players. Data sources are FIDE (period since 2001) and OlimpBase (period 1971 to 2001). The Elo numbers were added to the Wikidata items of the chess players, so any errors or missing Elo numbers must be corrected or supplemented on Wikidata.
The uci_limitstrength parameter tells engines with this feature to play at a lower level. The uci_elo parameter specifies the Elo rating at which the engine will aim to play. Engines that have implemented uci_elo include Delfi , Fritz , Hiarcs , Houdini , Junior , Rybka , Shredder , Sjeng and Stockfish .
The best calculation of symmetry is achieved by limiting one pawn to 24 squares in the rectangle a2-a7-d7-d2. All other pieces and pawns may be located in any of the 64 squares with respect to the pawn. Thus, an endgame with pawns has a complexity of 24/10 = 2.4 times a pawnless endgame with the same number of pieces.
