Yes I know it is easy to switch off this contempt factor but each time I switch between engines the default setting is restored and I have to do it over again. Does somebody has an easy fix for that?


Find the .uci file and add the following line to the [OPTIONS] section:
Contempt=0

Mine is at:
C:\Users\redacted\AppData\Roaming\ChessBase\Engines.UCI\Stockfish 9 64.uci

Does a 64 bit file work?

Edit - if you put a 32 bit exe in 'Program Files' instead of 'Program Files x86' perhaps the OS balks?

I think that's the message you get when you try to run a 16-bit .exe on a 64-bit system.

Edited:
I just downloaded from the amazon link.
$ stockfish_9_x32_analysis.exe
Stockfish 9 C0 by T. Romstad, M. Costalba, J. Kiiski, G. Linscott
uci
id name Stockfish 9 C0
id author T. Romstad, M. Costalba, J. Kiiski, G. Linscott

option name Debug Log File type string default
option name Contempt type spin default 0 min -100 max 100
etc.

I am on Windows 10 Home, 64-bit.

What version of Windows are you using, Tony?


I'm on Win 10.
From the command line I get: 'stockfish_9_x32_analysis.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.'

@brabo - Thanks for pointing out the Contempt. I didn't notice that myself so probably would have made some strange decisions based on it.

@GMTonyKosten - I was pretty sure those errors did not apply to you, but it is hard to think what else might be wrong with your setup, besides a bad compile which you have no control over. I can't download proustikeen's version on this machine, but I can try it when I get home.

It is possible to run the engine from the command line to see if everything is okay. Here is a session I just did on the official release. My commands are in bold. The difference is not quite 20 centipawns, but it's close.

What version of Windows are you using, Tony? I've only tested on 8 and 10.

  • It should be unzipped before finding it in the Create UCI Engine dialog.
  • ChessBase says it doesn't matter what folder the engine is in, but it was suggested on the web that it does matter. If you have a working engine then try a folder in the same neighborhood.


  • Yes, I unzipped it and put the appropriate files in an adjacent directory to the Stockfish 8 one.

    Did you unzip the file and extract the folder with the uci engines in it?

    A couple of ideas.
    1. It should be unzipped before finding it in the Create UCI Engine dialog.
    2. ChessBase says it doesn't matter what folder the engine is in, but it was suggested on the web that it does matter. If you have a working engine then try a folder in the same neighborhood.

    There are four different compiles in the zip folder, and you should choose one according to the notes in the info.txt and on the website. (You want to match your processor.)
                       


    I tried downloading again but when I 'Create UCI engine' and find the .exe file nothing happens, no name, no parameters.

    The file host is serving up bad ads. Let me know if this is better.
