AlexChess wrote: Wed Sep 08, 2021 11:47 am Thank you! Since there is also a popcount version, I will test it soon. With NNUE the quantum leap is certain (when you will add it, please make it usable also without AVX or BM2 :wink: ) . TIP: I'm dreaming about an engine capable of positional sacrifices (eg: giving a pawn or knight with no material compensation, but leading to a winning position, out from endgames solved by tablebases) . Do you think that it would be possible to add patterns for that?

Best regards, Alex
Well, there are no plans on replacing evaluation with any type of NN in the near future (lets say a half a year or so). I would say that Drofa handcrafted eval has some potential and can still be massively improved.

As for style.... Well, I dont really know about the method of doing it. Especially if coupled with the goal of increasing elo
Just testing it. Also my test confirms 3000+ ELO even without tablebases. It's very fast on my hardware: 4 mN/s :o
I will post here all the games played against 60 top engines 300/40 + 300/40 + 1 secs / all and in the meanwhile I offer you my customized logo :)

Anybody else having problems registering this engine in the Fritz gui? I select the engine but clicking on "Ok" to complete the registration does nothing. Seems to work just fine in Arena.

Hello.
I`m aware of this issue. Currently i`m mostly taking a break from Drofa developement, but i`ll try to figure it out.
It wouldnt be fast though, as I dont have Fritz GUI myself.

I looked at some of the games yesterday, some of them were very curious. Thank you.

btw. At least in my social circle, Alexander is shortening to Sasha, while Alex is short for Alexey. :wink:

@Alexander I'm with you Sasha! Continue to improve it.. It's a good engine even without NNUE!
