Chess System Tal 2.1 EAS

[Ponti]

Hi... does CST 2.1 EAS run under Linux ? Is there a binary already made, or do I have to compile it ?

Some of those games are just unreal, what an engine!
I downloaded the executable from the rating list site. Is it self contained or do I need a NNUE file to get the amazing chess it plays?
I've left save/load NNUE fields empty and it seems to work. No multiPV mode. Is all of that expected?

Yes. No separate NNUE file.

I think only Windows exes are available, and it is closed source. I might be wrong. Perhaps it runs under WINE.

And not to forget: CSTal does not support to use more threads on a machine than there are physical cores. And the max. number of threads is very limited (max 64). So, no TCEC, not only no multiPV analysis and no Linux and no Android binaries, no skill level for humans, closed sources and no support for Syzygybases.

But perhaps you try out Patricia 5 instead? Patricia is open source, plays incredible aggressive (and not to forget, around +100 Celo stronger than CSTal 2.1 EAS), has a working multiPV analysis, a skill-level system, supports real multithreading (runs fine in TCEC), supports Syzygybases and Jim Ablett made great binaries: Windows, Linux, Android.

So, the playing-style of Patricia 5 and CSTal 2.1 EAS is quite similar (and really great!), but in all other aspects, Patricia is way better.

I don't think this is true at all. Patricia and CSTal play a completely different game of chess. What you personally like better, is a matter of taste of course.

I think both you and Ed do interesting things to try and make the question of style more measurable, but the personality of an engine can still be all different even if they score highly according to similar parameters.

A very classical though most mysterious parameter that people tend to appreciate and value highly is to play "human-like". I personally feel CSTal is way ahead in this regard.
