PlentyChess 6.0.18 wins New Amateur Engines Test, 2025.09.18-23

-

PlentyChess 6.0.18 won the amateur chess engine tournament on a 12-year-old computer. Caissa 1.23 came in second, and Boot 7.4 came in third. Incidentally, we should add that for the first time, the tournament was run on Windows 11, which we managed to install despite hardware limitations. And the "rugged old" laptop works.

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.
