So are you also going to the forums of racing car drivers and tell them what a shame is it that they drive their cars instead of using their feet and their feet only to run in competition?

It is true, because when contempt = 0 it refers only for static contempt.
"Tempo" is also a contempt as a fixed parameter for White.Frank Quisinsky wrote: ↑Sat Jul 04, 2020 1:02 am Hi,
Contempt is an interesting topic.
We can make weaker engines in a rating list stronger if we give a negative contempt.
We can make stronger engines in a rating list stronger if we give a positive contempt.
So what is to do?
Contempt = 0 for all.
But we create a new problem with it!!
Engine programmers set such contempt parameters in sources without to give a parameter for it.
Can be see in statistics with move average.
If an engine have no parameters for contempt but a clealy lesser or clearly higher move average at all the others ... in most of cases the reason that the programmer set contempt things directly in sources. And Bingo a problem for a rating list if you set for all the others Contempt = 0.
This is one problem if we are looking on results from a rating list.
So I am looking not on Elo only because I can see nothing about an engine.
I need a lot of different statistics before an engine goes in my personal TOP-10.

Houdini has a setting called "Analysis Contempt" and is described as:
there was more....By default a non-zero contempt is only used during game play, not during infinite analysis. If you enable the Analysis Contempt checkbox, Houdini will also take into account the contempt for infinite analysis. Because of the asymmetry in the evaluations (the evaluation changes when you switch sides), this is usually not recommended.
Analysis Contempt (checkbox)
Activate Contempt for position analysis.
It is usually not recommended to activate the contempt for analyzing positions.
When contempt is active for analysis, the score of the analysis will be optimistic (over-evaluated) for White if the Contempt value is positive, and optimistic for Black if the Contempt value is negative.
Houdini has a completely different Contempt than Stockfish. Actually, Houdini's Contempt preceded Stockfish, and did it better (decreasing Stockfish's contempt to the negative always reduced elo. Houdini's negative contempt actually improves its Elo against stronger opposition.) Houdini basically detected when the lines were too dangerous and shut down contempt by itself, very dynamically (where "dynamic" is completely unrelated to Stockfish's dynamic contempt.)
