Integral 8 - new version chess engine

Integral - UCI Chess Engine
Author - Aron Petkovski  Rating Chess Engines Diary CEDR=3816

The Integral engine, ranked among the top 64, competes in the CEDR Chess League. In the 09/2026 season, it played in the Second League and finished 6th, missing out on promotion. Will this version step up and secure a spot in the First League in the 10/2026 season?


What's new?:
Notes
It's been over a year since the last Integral release — apologies! However, this version is much stronger and supports DFRC play, hopefully offsetting the wait for a new release :)

Network Improvements
Dataset grew to 16.7b unfiltered positions
Threat inputs
50-move rule inputs
Less notable things that I can't remember
Search Improvements

SPSA tunes (latest tune optimizes for SMP conditions)
A plethora of search patches
Special thanks to everyone in my OpenBench instance and the kind, helpful people in the Stockfish discord.

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...
