In the personality folder there is a personality built with human games fromLichess database, I don't know if it makes Cheese play more human like,
but you can try it with UCI parameters UsePersonality to true, and PersonalityFile to personality/human_lichess_2019.txt (or changing the parameters in cheese.ini)
Using these evaluation parameters Cheese strength is reduced by 50 ELO, you can reduce the strength more with StrengthELO and UseStrength parameters.

Cheese 3.2.1 is available :

http://cheesechess.free.fr/en/index.html

- Fix an initialization problem with LimitStrengthMode UCI parameter
- Fix tablebases UCI parameters limits
- Improve the code to limit nodes and speed
- Change UCI Elo formula
- Simplifications in move generation and evaluation

I tried to tune the ELO levels based on CCRL 40/4 ratings (2024/01/14).
My results are based on games at 2m+1s (using an AMD Ryzen 7 5700x),
and I'm using Pigeon 1.5.1 rating as offset (1739 ELO).

By default Cheese limits the search speed, there is an UCI parameter
"LimitStrengthMode", to choose between limiting the speed or limiting
the number of nodes.

- Reducing speed :

Is it a problem with the website or Cheese binary ?

Note that Cheese website is not https but it's only pure html (no javascript)

No probleme here with Microsoft Defender.
Can you report it as a false positive ?

You can also compile it by yourself from here :
