A week ago I decided to do some contempt testing, so far only 2 data points (1 match lasts about 3 days). The plan is to pit SF20102019 bmi2 against SF10 bmi2, H6.03 x64-pext and K10 to cover close, mid-range, and weaker opponents over the range of contempt values - if I don't lose interest first.
Games - 1,000 games per match
HW - i5-4670k @ 4.3 GHz
PB - Off
TC - 1m+1s
Hash - 1GB each
TB - full 6 men syzygy on SSD
Book - ICCF database limited to 3 moves
Next up SFc20 vs H6.03, will report here.
