I do not recommend using contempt for analysis all the time. In going from SF8 to SF9, they changed the default contempt setting from 0 to 20. Possibly inspired by the asmFish project to speed up Stockfish using a programming language closer to the machine, the purpose of CFish is to explore possible optimization issues of C versus C++ compilers. Stephano uses a funny metaphor when he threatens to make a ‘stockfish’ of Trinculo (this is a fish that was bashed to make it tender). 1! It is that close that the next new entry might change this! New anchor for the lists is Stockfish 5 Syzygy with 3113 Elo. This is true, Stockfish expects its opponent to play as well as itself (outside of the 'contempt' setting, not sure if that was used or tuned per game). Stockfish also referred another famous "little fish", the then strongest chess engine Rybka. Comunque sui motori minori SF ottiene un risultato eccelente, segno che come sostenevi tu un'aggiustatina al contempt ci voleva (sinceramente prima non ci credevo tanto). 08-07-2019 - The Contempt-Coherence factor on Stockfish. Es definiert eine Art Remiswert. In Stockfish 10 the contempt factor is now standard set at 24, in Komodo at 16 and in Houdini at 20. The Stockfish team is still deliberating over the best default contempt value in self-play and the best contempt modeling strategy, to help users choosing a contempt value when playing against much weaker programs.
