ShashChess

For now, I'm aligned with stockfish, but I can easily add a similar button.

That would be great!

Hi Andrea, could you compile an Android Armv8 Version ? I'm playing on DroidFish with SD865 processor , it's very strong. Thanks.

I'd like, but I'm not expert on android systems.
An expert told me the problem is curl library for livebook.
I hope someone will be able.

Thanks, Andrea!
Modern compile works well with Xeon X5670.
Hybrid- Pure- Classic- button is a very useful tool!

An intermediate result in my test (hybrid option):



A nice and interesting engine. As always.

Removed USE NNUE combo: only pure NNUE or classical for ShashChess
A lot more hard positions solved and at least the same playing strength as Stockfish hybrid approach.
This will also speed up the engine.

Thank you Andrea !

Question: Why did you remove the 'option' for hybrid?

Thank you Andrea !

Question: Why did you remove the 'option' for hybrid?

Because, based on the tests, hybrid version solves a lot less tactical positions and there is no advantage in match play.
The flexibility is guaranteed by Shashin theory. Moreover, the engine is a lot faster with this boolean option respect to a combo.
