Stash - UCI chess engine  Rating CEDR=3408
Author: Morgan Houppin 

Stash is a UCI-compliant chess engine developed from scratch. Preferably used
with a GUI like Arena, CuteChess, Fritz, etc.

v.37:
Bump the major version, and update copyright years.
Additionally, fix a bug affecting the sign of search scores in the tuner
when Black is the side to move.

Which binary should I choose ?
The latest release should always be the best. The different architecture builds are:
🖳  64: generic 64-bit build. Should work on all 64-bit processors of your operating system.
🖳  - x86_64: x86_64 build. Same as previous one, but enables use of the prefetch` instruction, which places RAM addresses in cache for faster access. Should work on almost all 64-bit processors.
🖳 - x86_64-modern: same as previous one, but also enables use of the popcnt` (Population Count) instruction. Should work on all > 2006 64-bit processors.
🖳  - x86_64-bmi2: same as previous one, but also enables use of the `pext` (Parallel Bit Extract) instruction. Should work on all AMD processors with Excavator arch or newer, and all Intel processors with Haswell arch or newer.

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...
