This is the testing instance of LCZero server. It is also the only instance.
Here we pretend to test things out, but sometimes we just make the strongest publicly available chess playing neural net by accident.
The current main test is to see whether we can train a much larger net to improve even further on our previous best..
Secondary test is a small net establishing a new baseline for future testing due to several recent bugfixes of importance. It can be found under the training runs section.
Finally there is a third test attempting to see if we can tweak some more strength out of our previous best run.
You can get the client and lc0 releases from those links.
