Re: Capablanca Random Chess engines.

A first working version of Durandal is ready. Certainly the weakest engine available. :wink: I see durandal32.exe and durandom32.exe there. What is the difference? And will the "durandal32.exe" -fd "C:\Program Files (x86)\WinBoard-AA\WinBoard\WinBoard\Durandal" /variant="capablanca" -fUCI command w...

Re: Capablanca Random Chess engines.

Pingy is a private CRC and Gothic Chess engine of 2007 that i was given for beta testing by a well known commercial author. It was a little stronger than Gothic Vortex. It's irrelevant now. Well, if Gothic Vortex and Pingy could participate it would make sense to do a new tournament. Does Pingy use...

Re: Scorpio 3.0.2

But install.bat does not even work for me and crashes. So no luck to go further down the steps. I can see on your screenshot, that you located Scorpio in C:\Program Files that could be a problem, because this is a "restricted area" of Windows, where writing in files/folders can be a problem. Perhap...

Re: Scorpio 3.0.2

I wish it would be that easy as Leela. Download the files and run them. :( Yes, but if you follow the 3 steps, I described here, Scorpio should work. But install.bat does not even work for me and crashes. So no luck to go further down the steps. But I agree, the setup and handling of Scorpio is a n...

Re: Scorpio 3.0.2

Does not work for me either.
ScorpioNN installation with the install.bat failed for unknown reason (Threadripper 2990 WX, RTX 2080+2060, 64 GiB RAM, Microsoft Windows 10 x64 pro).

Re: Lc0 + 320x24.J13B.2-swa-136000 vs. Stockfish 250919 TC= 30m+30s

I will tell you. If you are setting Lc0 for maximum NPS. You are on the wrong path. NPS with Lc0 is a false flag. I tune it by time to depth and GPU loading. I ignore NPS results. Tuning Leela according to depth is a very bad idea and it's pointless and dangerous. Dangerous that you will end up wit...

Re: Hard-Talkchess-2020 set

Results for Stockfish_19091615_x64_modern on a i7-4930K (6 cores), 15 minutes per position in the next message. Final version will be published in next month. I hope there will be no change. Still to do : numbering each position, add a pgn for solution, add source, create "study" for each position ...
