Re: Database snapshot

Use fen and not epd. If you only have epd, just add "0 1" at the end to make it a fen. Thanks, now it works. This is really cool, I kind of feel like I downloaded some huge database that weighs just 9MB :) Also working on simple html interface, I hope to release it next week. https://i.imgur.com/RO...

Re: Poor performance of Stockfish 10 against Igel 1.8.3 at (shallow) fixed depth=10

Hello everyone, I am trying to hunt down some issues in Igel ( CCRL 40/40 ~2800 elo ) when running games at a very quick time control, and one of my ideas was to measure the "time to depth" in Igel as well as see if I should improve evaluation or search. So I decided to run a few games between Stoc...

Re: Banksia - Yet another Chess Tournament Manager

I set concurrency to 1. My computer can handle even up to concurrency 8, at least when I use winboard and cutechess. Oh, I see. Amazing your system can run safely with 16 engines at once! Give me few days for checking since I don't have any Win 7 system at home. I think I found the issue. Setting m...

Re: Banksia - Yet another Chess Tournament Manager

Thanks for your feedback. Unfortunately, I cannot reproduce the crash. Can you give me some more information: What is the Windows version, 32 or 64 bit? How many (real) cores and memory does your computer have? Please try: 1) make sure the tournament won't take all your computer resources. In gener...
