Engines tested at 30 sec and one core. 200 positions.
Testsuites are not useful in development, but afterwards they can confirm progress nicely!

Crystal 2019 is here not as good as Houdini Tac, but of course the second best engine. In some other testsuites it's better than Houdini. BTW when are engines tested at TCEC hardware 176 threads?

Houdini tactical in i5/4 cores: 5 sec 49/213 and 5 min 146/211. I expect positions are not much changed from 2019.

Wow 21750 games in 2 days! Really?

This is a good suite to test progress from 2008! I ran positions with Crystal 2019 in corei5/4 cores 1GB hash and 3 minute. It solved 39/40 in first run (claimed or faster mate). Only unsolved position was solved with 2. try. Serious progress :D :!: . I have removed Chest some years ago from harddri...

Definitely average or more games is needed there! It's always funny when "Update Readme.md" gaves +5 ELO !

Of course I mean 3-6 piece. And 3-4 gave nothing as SF has basic knowledge.

2-6 pieces and up to 80 000 games. But I don't find it anymore. Where is it?

Try faster engine like Houdini 6! It has 50% higher NPS should be 450 000 000 easily . Also Crafty and Deep Fritz 12 have very high speed. SF is only average in node speed.
