Re: How long for you to detmerine that this position is dm35?

Re: this will be the merge of a lifetime : SF 80 Elo+

This is the breakthrough I've been predicting for years! It finally happened, and I'm just glad chess looks very healthy after it (draw rates have gone down! Some lines are proving to be playable again!) Until everyone uses these? Everyone is already using these, when Eman Enigma 1.00 (closed sourc...

Re: An amazing net for SF-NNUE.

Trained on Reinforcement Learn and fine tuned using CCRL games: https://www.dropbox.com/s/71qy3j8gtgch2ss/qh-fine-0803-5.zip?dl=0 How does this net fair against some of Sergio's more recent nets? I tested it vs. SF 200717, like all S.Vieri nets. Look here: https://www.sp-cc.de/files/ergebnisse_nnue...

Re: SF-NNUE going forward...

It seems to me that the size of the net that is optimal is likely a function of the power of the computer. A one core Pentium would need a tiny net, and a 128 core dual Epyc would be able to use a much larger net. I don't have any proof, just another thought experiment It seems to me that if you ar...

Re: SF-NNUE going forward...

Zen: Thanks for the explanation. I was wondering about the size of Sergio's NN_SF nets at 20 MB. How does that compare to the size of the lco nets; and why not create much larger NN_SF nets? Lc0 nets are much larger and have a different structure. They run best on GPU's which limits their usefulnes...

Re: SF-NNUE going forward...

I've noticed some unusual and VERY interesting behaviors as well. Yeah, I had a record time of analysis obsolescence. Before NNUE I could count about a 11 months window (analysis from around September 2019 was becoming obsolete.) After NNUE, I can say that ALL my analysis with Stockfish dev became ...

Re: New chess rig

FYI, I flashed the BIOS to the latest version and then it worked (fortunately Gigabyte has a way to do this via USB that runs off a ROM and so does not even require a bootable system). --Jon Many new MB have this feature. It saves MBs from being bricked if the BIOS gets corrupted. This didn't use t...
