Thanks for making these available. I was wondering about the following harm.bin , is that an aggressive net? Noob3.bin .handicapped net? and salc.bin?Thank you

https://github.com/glinscott/fishtest/w ... -Stockfish Addresses Noob3.bin and salc.bin
harm.net is the Harmon.net https://www.patreon.com/posts/harmon-nnue-44549655

Thank you for the reply and drawing my attention to the stockfish wiki links.

Can you post Windows binaries for regular 64bit machines. Somehow the *.exe on Github doesn't work on my Win 10

Some quick conclusions: using nets has changed everything, the best way to get more variety now is to use different nets , stating the obvious, but that certainly made clear here
Cfish is an outlier, an outlier to the upside. It is is much more than anything I ever experience previously. Not to be an alarmist , but perhaps a very subtle bug has been introduced with the official Stockfish that is not seen in current cfish. Version R07 is from Nov 20th, considering virtually no gain since 11/20, if there is bug, it was probably introduced after 11/20.

Hi Mike

Is there any chance of displaying the engine you are playing against instead of Black Diamond always appearing at the top of the board?

Thanks for that Mike.

Looking good with the new piece sets.

Great app
