Chess engine: Bread Engine 0.0.5

-

 

Bread Engine is a chess engine written in c++. I started working on it in 2021, and only just finished. There is still a lot of room for improvement, but the engine is quite strong (for humans, at least). It uses NNUE (efficiently updatable neural network) to evaluate positions, as well as minimax search.

Bread engine does not have a GUI built in, however it supports the uci protocol, you can therefore run it on any chess GUI.

Author: Nonlinear2

Improved UCI commands, neural network is now always embedded in the executable. Bread engine is now a single executable, that you can download and run directly.

v.0.0.5:
Bread Engine 0.0.5 has cleaner code, and a bug concerning the tablebase probe has been fixed. Bread engine now supports the Clang 17, and GCC 13 compilers. Version 0.0.5 is around 30 elo stronger than version 0.0.4.

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...
