Stockfish 14.1 is (almost) out!
Tests running as soon as the official exe will be available.

In bullet rating, around +20 compared to v14. But this figure is not as important as the loss percentage, one third of the previous one!

The compile from 21 October gave +22

http://rebel13.nl/grl-40-2.html

[Wolfgang]

In my test for our 40/4 it is even a bit more for SF October 21st: +26 from 2000 games

Just running Stockfish 14.1 vs. same opponents, same machine, mostly same opening suites

Walleye 1.5.1
Thanks to the Author Mitchel Paulin
chess engine written from scratch in Rust

https://github.com/MitchelPaulin/Walley ... /tag/1.5.1
Fixed issue where Walleye would have high CPU usage across multiple cores even when only using one thread to search .

I am doing the same in the hope one week work pays off.

The option he lost to Koivisto is probably pretty bad. It's starting to look to me like Stockfish won't lose from an even position anymore - a miracle in many games.
These fights seem to be decided by the ability to keep the bad ones and win even marginally better ones anymore.

Nice! Seggz and Caffenaited Pawn also use more than 1 core when playing single thread. Lynx does it too, but I think that is on purpose.

Nice! Seggz and Caffenaited Pawn also use more than 1 core when playing single thread. Lynx does it too, but I think that is on purpose.

Rustic also potentially uses 4 cores when playing, because it has 4 threads active: engine, search, input, and output. For searching however, it only uses one thread (at the moment). So if you run it on a quadcore, it uses 25% of the CPU plus some blips on other cores here and there for the i/o threads and engine i/o handler of the main thread.
