cozy-chess VS fishtest

If you'd like to reference something, my movegen crate cozy-chess does this. I also have a standalone reference implementation here as part of my magic bitboard article.

https://github.com/ShailChoksi/lichess-bot is a straight forward way to use any UCI engine with lichess. There are also a few libraries for move generation mine: https://github.com/Disservin/chess-library , libchess: https://github.com/kz04px/libchess , surge: https://github.com/nkarve/surge . These are C++ ones, for rust theres https://github.com/analog-hors/cozy-chess . In python you could use python-chess but its incredibly slow for engine stuff writing your own will probably be faster if you know what you are doing.

A while back, I got into computer chess. I used Jordan Bray's neat chess crate for move generation, and was pretty satisfied until I took a look at the code. It's pretty good and all, but... So. Much. unsafe. Out of a mix of frustration and curiosity, I made it my next project to create my own chess move generation library. So... here it is, I guess: https://github.com/analog-hors/cozy-chess/ It's my first crate, so feedback would be appreciated! It's currently being used in my (weak) chess engine Tantabus.

you can have a look at openbench maybe, https://github.com/AndyGrant/OpenBench . It is currently a testing framework for chess engines (only invited ones) or fishtest. https://tests.stockfishchess.org/tests Stockfish testing framework. Both of these test if change A beats the master version using statistics. Both look at the git repository and download it and create/compile the engine, that might be another solution for you.

FishTest has thousands of computers running 24/7 https://tests.stockfishchess.org/tests. Nerds at gcp,aws,universities burn thousands of GPU hours on lc0-client just to watch their GPUs warm up. They aren't just attaching 20tb of endgames to an old macbook.

if removing any rng from stockfish would gain elo it would be merged. If you think it gains elo feel free to submit a test to https://tests.stockfishchess.org/tests , but it doesn't so what your saying makes no sense.

Where did you get these numbers from? https://github.com/glinscott/fishtest/wiki/Regression-Tests shows an elo difference of 351.3 elo points. This is further exaggerated by the fact that sf9 lacks nnue and is particularly weak at the starting position and consequently 960 starting positions.

In https://github.com/glinscott/fishtest/wiki/Regression-Tests you can see 8moves_v3.pgn opening book (09/11/2013 - current) with a link:

You can see the various code changes in https://github.com/glinscott/fishtest/wiki/Regression-Tests . Both the actual change and the elo change from the code change.

Current progression test is still in progress but you can see all of the previous ones here: https://github.com/glinscott/fishtest/wiki/Regression-Tests
