Incognito 020823

[Eduard]

UCI Engine INCOGNITO. This is an experimental version of CorChess with very large network (dimension 3072). The network "nn-4ffa203f3b58.nnue" was released today and I tested it. Especially with very long analyses, the evaluation in the middle game is very interesting. CorChess has a slower search than SF dev and will find more with enough time. I love it! MinimumThinkingTime, Polyglot books and self-learning in Eman style are implemented. External network. Remember: The network is very large. Therefore this engine is not suitable for very slow computers!

I would be interested in your opinion. The network is very large and the engine calculates slowly. Would such an engine be OK for your analysis, or should the engine have a faster search - and maybe a smaller network?

Interesting... I will test this engine.
Thank you for preparing it and making it available

I have compiled Incognito-020823 version for Mac with Apple Silicon processor - downloadable from my site (Files section).

Thanks!

I've done more testing and now I have the impression that this large network doesn't quite suit an engine that has a slow search as CorChess. In my opinion, CorChess runs wonderfully with nets up to dimension 2048, with larger nets such an engine seems to be overwhelmed. Unfortunately.
