A little fun before coffee in the park. My RUST_TOURMAMENT has a new competitor! The engine is a university thesis in Warsaw.

For when you return to the Python league, please note that I have fixed some bugs and added some minor enhancements to uSunfish, reducing the likelihood of blunders.

As with the previous release, the PyPy build of uSunfish 1.2a is the strongest one. According to my own tests, it might be able to reach a position somewhere between Numbfish and KiyEngine, though of course your tournament conditions may give a different result.

This time I packaged it as a single executable using Enigma Virtual Box.

CODA continues its way to the podium. As of today it has a new net, very sophisticated......and very powerful. An exceptional engine. Today I compiled it again....a masterpiece by Adam Twiss & Claude AI.

[DreamerExx]

By the way, according to my measurements, the version of 0.9.4 was about 2240~ elo, at the moment I have already raised the level to 2360~ and I am working on the NNUE evaluation, would you like to see the release version of Ember at your tournament when it is ready (maybe in a few weeks), I expect about 2500 elo from the release version of Ember (Elo I change according to the system that drives the match between stockfish and my engine of different levels, stockfish becomes stronger until the percentage of wins of my engine does not reach 50, and then another 500~ games for accuracy)

Well, I had a great time today. I compiled and introduced into my tournament (RUST_TOURNAMENT) one of the most powerful Rust engines on the market. Sure winner of my little tournament. In league with CODA, Reckless & co.
