Re: CTF Survey

I vote 3. I used to be a frequent poster there, but left many years ago when the nastiness level became unacceptable. Nonetheless, a small fraction of posters there do produce civil and thoughtful/meaningful posts that add value. So, for their benefit, I'd like to see continuation. But many others s...

Re: Lc0 with latest test30 nets is vastly superior positionally

Hello Kai,

Please also test the latest iteration of Fat Fritz. I'm a fan, and curious how it compares to Leela and Stockfish NNUE.

All the best,

Re: Stockfish Abrok August 24 Engine Failure

Hello All, I finally got Stockfish NNUE to work! But first, I hereby thank those very kind people who took the time to try to help me. THANK YOU! Those who mentioned that as of August 20, the Stockfish NNUE updates now have the USE NNUE box already checked were correct. That was the problem, althoug...

Re: Stockfish Abrok August 24 Engine Failure

Hi Louis, The "default" NNUE file has not changed. It's still the same one I already use for the August 20 version that runs perfectly. The order of events are: 1) First change the downloaded engine to a .uci engine 2) Run that new .uci engine 3) Establish parameters with the related NNUE bin file H...

Re: Stockfish Abrok August 24 Engine Failure

It might help if you posted any error messages you received. Hi Louis, There's nothing special regarding the error message. It's just a ChessProgram17 pop-up box following the engine crash after being loaded. It states: "Stockfish 240820" caused an exception. This is a problem in the engine. Then i...

Stockfish Abrok August 24 Engine Failure

Hello all, I've been a long-time user of Stockfish's free development iterations at the abrok website. I'm using the August 20 iteration presently - it works well. However, after downloading the latest August 24 version and converting it into a .uci engine, I got an engine failure error message. I t...

Re: Stockfish NNUE Questions

Hi Louis,

I'm TalkChess' resident computer dummy. Nonetheless in your display, we see: popcnt = yes. Doesn't that mean popcnt is still used by the AVX build?

ifeq ($(ARCH),x86-64-avx2)
arch = x86_64
prefetch = yes
popcnt = yes
sse = yes
ssse3 = yes
sse41 = yes
avx2 = yes
endif

Regards,
-Steve-

Re: Stockfish NNUE Questions

Hi Dann,

I was like you in running only Modern. But Corres is correct that the AVX build seems a bit faster.

Re: Stockfish NNUE Questions

Thank you, gentlemen! That's good to know. Anyone have any input on Question #2? Although I'm an ICCF GM, I'm a computer dummy. So, I value what I can learn from you experts at this website. And since I'm showing my computer ignorance here, please allow a third question, which I hope isn't too stupi...
