The goal: every position has exactly one winning/drawing move to find! How many are then left? 50?

Re: Crystal 3.1
With "clean search" I got mostly better results in testsuites with Fritz. Arena does always engine re-start in every position so not needed? But I noticed really weird thing: with one core and "clean search" Crystal crashed always in Fritz! Sooner or later engine speed goes to 1-5 knps.

Re: Some beginner questions about Lc0
One more.I have read, that Lc0 needs a lot memory to run well. But how do You increase memory? Even if I increase hash to XX GB and NN cache to zillion system monitor says always about 2 GB GPU memory used and 15% of GPU power. System monitor sucks I quess?

Re: Crystal 3.1
Fully agree Dann. There should be warning in Crystal page: NOT FOR PLAYING!
