Stockfish13 release

[Scally]

Hi all,

Stockfish13 has been released this afternoon.

You can download here as a-stockf:

a-stockf
https://www.dropbox.com/s/zum898zc3uon5pr/a-stockf?dl=0

All you need to do is copy it to /opt/picochess/engines/armv7l/ and give it executable rights via:

cd into the folder you’ve copied it to

then:

cp -r a-stockf /opt/picochess/engines/armv7l/

cd /opt/picochess/engines/armv7l

sudo chmod a+x a-stockf

then edit the the engines.ini file

sudo nano engines.ini

then replace these 4 lines in [a-stockf] 

name = Stockfish 12

small = Stf 12

medium = Stocf 12

large = Stockfish12

with

name = Stockfish 13

small = Stf 13

medium = Stocf 13

large = Stockfish13

Save it and reboot.

That’s it.

Cheers,

Al.

Hi Al, 

thank you for all your job maintaining picochess engines updated to the last ;)

Thanks, Al.

For anyone using my v3 images, you will have to copy it as sudo:

sudo cp a-stockf /opt/picochess/engines/armv7l/

The rest is the same. If you have this engine in your favorites, make the same edits to favorites.ini as you made to engines.ini.

Hi all,

I made a mistake, sorry.

a-stockf and it’s associated a-stockf.uci works fine as a Picochess engine.

However PicoTutor runs a-stockf without the uci file, therefore fails as I removed the embedded NNUE file in the first compile to make it smaller.

I have replaced a-stockf in the same link as before:

a-stockf
https://www.dropbox.com/s/zum898zc3uon5pr/a-stockf?dl=0

This version works both as an engine and with PicoTutor.

For those of you who have already downloaded this file, you will have to do it again, sorry about that.

Al.

Hello Scally. Be so kind and let me know when an img stockfish 13 (or SF 13 NNUE) for v3 SD card is available. Greetings Peter

Hi Al,

thank you for your mistake ;) this give me an idea that I just implement.

I keep Stockfish 12 and rename Stockfish 13 to a-stock13 using your tiny compilation, probably I was the first one to download it, then when I see your correction what I did was download your second compilation and rename it to tutor-engine and change line 107 in picotutor.py to refer to tutor-engine, so in this way I keep Stockfish 12, update picotutor to last stockfish 13 and for further updates just need to rename picotutor analisys engine to tutor-engine  ;)

Thank you

Kiko

Very soon, Peter.
