New version chess engine: Fructosita 1.1.0, ZeroG 1.0.0, Onyx 1.6

-


Fructosita is an open-source UCI chess engine written entirely in Rust.
The project began on July 2, 2026 as a personal initiative to learn chess engine development from scratch. The name Fructosita was inspired by the author's undergraduate thesis on fructose, eventually becoming the engine's permanent identity.
The long-term goal is to evolve Fructosita from a classical handcrafted engine into a modern competitive chess engine featuring advanced search techniques and, eventually, an NNUE evaluation.

ZeroG is a high-performance chess engine written in C99, featuring a hybrid board representation, magic bitboards, Zobrist hashing, transposition tables, and a Universal Chess Interface (UCI) protocol engine loop.
Author: Kristian Ekman



Onyx a UCI chess engine written from scratch in C++, with a self-trained NNUE evaluation. Estimated strength: ~3200.
Onyx was built and trained on a single desktop PC (Intel i7-11700K + RTX 3070) — the neural network's training data was generated entirely by the engine playing itself, with no external datasets or pretrained weights.

We already have the new Fritz 20 program - what does it look like and how does it work?

The purchase process for the download version on the ChessBase website took only 5 minutes. Downloading the files from the cloud was even quicker. The installation itself, which involved five large files, took maybe 7 minutes, including restarting the system and entering the serial number I received upon purchase. The start image for Fritz 20 has a strange mosaic of colors; perhaps I'll get used to it. As you can see in the second screenshot, the program interface hasn't changed much; only the icons are different (we've been using Fritz 17 until now). It looks nice, but it's no major revolution. The next two screenshots show engine management and the installation of the UCI chess engine (here, Cataphract 1.1). As you can see, there are no changes. Screenshot no. 5 shows the analysis of some position by Fritz 20 engines. The changes are minimal - it is still very legible. Finally, on screen 6 we have the engine tournament table generated by Fritz 20 . I think it is sti...
