When there is new engine or network improvement… the settings that once worked will no longer work. You will have to find new settings that will work with latest engine improvement. dkappe you should stop beeing lazy and try and tune the engine yourself. Don't expect others to do your work for you…. :wink: :wink: :)

I’ve heard rumors that CB got the tuning wrong. Hopefully an update is coming soon.
For the OpenCL build yes, but the CUDA is as tuned. Otherwise anyone can enter the new tuned values manually.

The latest update is Fat Fritz 1.1 with changes to Cpuct, Fpu, Policy temp, NN cache and couple of others.
Tests are required to see where it stands.
Question is whether Kiudee settings work with Fat Fritz 🤔
if Fat Friz.exe is equivalent to lc0.exe as it was, yes.

The Dorf-off is now complete. FF had a slight edge in the Najdorf with t60 underperforming.

Code: Select all


   # PLAYER    :  RATING  ERROR  POINTS  PLAYED   (%)  CFS(%)    W    D    L  D(%)
   1 FFv471    :      16     13   215.5     400  53.9      99   69  293   38  73.2
   2 SF11      :       0   ----   383.5     800  47.9      93   93  581  126  72.6
   3 62627     :      -9     13   201.0     400  50.2     ---   57  288   55  72.0

I’ll add some head to head in the Najdorf for good measure.

It seems as if t60 doesn’t really get the pawn structure of the Najdorf.
