The true hierarchy of chess engines written in Python. There are 12 more (all for the 2nd league). In total 42 engines that can withstand the demands of a tournament. Chessidle-1.4.0_x64 is a true masterpiece. 100% Python!

Python_1st_League_2026 after 958 games (TC=4'+2"):

[Sylwy]

My tournament PYTHON_1st_League_2026 now has 31 participants. I also introduced an engine (from Vietnam) with an interesting architecture: KiyEngine-5.0.0_x64-avx2. It has mixed code: Python (mostly in this version) and Rust. The evaluation is based on GGUF (BitNet 1.58-bit TransformerNN). The situation in the tournament after 1023 games is:





For example: a beautiful game of KiyEngine-5.0.0_x64-avx2 against a Polish engine - AllayaChess_1.6:

ChatGPT about KiyEngine-5.0.0_x64-avx2, current architectures, predictions about chess engine architectures in the coming years...

[Sylwy]

[Sylwy]

My first compilation of an engine written in Zig-NeuroSpeed. It comes from Ljubljana (Slovenia). It will play as the first guest in my PYTHON_1st_League_2026 tournament (it also has code written in Python). I can't wait to see how it performs against Chessidle-1.4.0_x64-avx2 and Blunderfish!

[Fizban99]

Hi Sylwy,

Would you consider adding uSunfish 1.1 to one of your Python engine tournaments/tests?

Repository:
https://github.com/fizban99/micropython-usunfish

Windows release:
https://github.com/fizban99/micropython ... s/tag/v1.1

There are two UCI-compatible Windows builds:

• uSunfish-1.1-micropython.exe
  • Self-contained MicroPython executable, around 900 KB
  • Uses frozen MicroPython code and @micropython.native
  • Around 2.6 MB memory usage
  • Estimated strength: roughly 1280–1350 CCRL Blitz Elo

• uSunfish-1.1-pypy.exe
  • Uses a bundled abridged PyPy package
  • Around 50 MB memory usage
  • Estimated strength: roughly 1520–1600 CCRL Blitz Elo

I know it is much weaker than the top engines in the current Python list, especially the NNUE engines, but the MicroPython build may be unusual enough to be interesting. The PyPy build is also included.

[Sylwy]

Would you consider adding uSunfish 1.1 to one of your Python engine tournaments/tests?

Of course, he is welcome!
In the meantime, I have added guest no.2 to the tournament: a very interesting engine written in Zig: Water. It has a very interesting implementation of NNUE evaluation.

[Sylwy]

I added it! Varna-Bulgaria?

[Fizban99]

I added it! Varna-Bulgaria?

Actually, I am from Spain.

The situation in my tournament Python_1st_Leagues_2026 after 1083 games (TC=4'+2"):



-marked in green-my Python favorites;
-marked in blue-the two guests from Zig's world;
-marked in red-the newest Python competitors entered the tournament.
