More details are here in this article: https://zahak.amanj.me/posts/meet-zahak-7/

TL; DR; the trainer is written from scratch, the data is from self-play, and you can train different nets with provided tools if you like

Elo estimation: +190 over Zahak 6.2

This is indeed great news and your cooperation with Aryan makes it even greater.

Edit: I can't find the network file.

Edit 2: I have found a default.nn but is that really so small?

[amanjpro]

The default network is embedded, but you can still load alternative networks

Does that mean that I may leave the parameter field for NNUE empty?

Ed, I am a bit puzzled about your version numbering?
What happened to Benjamin 2.0, which was already 'released' in 2020-10?

[Rebel]

It was a fun and misunderstood engine.

Misunderstood because some people started to play games with it and then complained about the results. Hence its removal. It was a fun tactical analysis engine just to show that playing games isn't the same as solving tactical shots. I am still toying with the idea to launch such a tactical engine as an second thread. I once did it with ProDeo 2.2, it gave elo but the communication between the threads wasn't stable. Maybe one day I will try again.
