DGT Pi New Book Upload

[Tobias]

Hello,

I would like to add a new book on the DGT Pi.

But I have a problem with the file upload. ( Permission denied )

I use picochess 0.9N with login "pi" and password "picochess" with W-LAN Connection. (Sftp Port 22)

It doesnt work with WinSCP or Filezilla :(

Could you please help me? 

Thank you :)

[RandyR]

Tobias,

I don't use WinSCP but I found this on the web:

• In WinSCP select Advanced and navigate to Environment > SCP/Shell

• Change the text in the field from default to sudo -s and your "pi" account will log in using sudo privileges, letting you SCP files anywhere as root.

Hope this helps.

Randy

Hi, now it is fine :)

Thank you!

I have another question...

I uploaded the new book with a lot of games with the Kings Gambit, but the computer is taking exactly the same moves every game?

At the standard books, example "Open-Book", the computer do random moves?

Could anyone help me?

[Scally]

Hi Tobias,

What’s the name of the Book File you added and have you added this book to the choice of books in Picochess?

Can you tell me the contents of your books folder via:
cd /opt/picochess/books
ls (That’s small LS) what files are in here
cat books.ini (This shows me which of your book files are added to Picochess)

Some book files are very limited, especially in lesser known openings. Others are huge, like the Cerebellum books, but these will only play the best line each time.


Cheers,

Al.

Hello Scally,

I made a own book with 1500 games from the king´s gambit.

I used the tutorial from Topschach Benny.

The filename is r-kingsgambit.bin

The book is working, but I would like different pc moves in various games.

Have you a idea?

[mvanthoor]

Hi Tobias,

How big are the variational differences between the games? There aren't many ways to play the king's gambit in a good way. If there are a few variations that dominate in your book, the engine may choose only these variations most of the time. You'd need to look into changing the weights of the variations and set them all to 0, so the engine thinks they're all equal and so will choose a random one

I know how to do it in Fritz (ctg books); I don't yet know how to do it in other software that makes bin-books such as scid.

[Scally]

Hi Tobias,

Can I have a copy to play around with, some engines have a uci option that may help.

What engines are you using?

Al.

[Tobias]

Hello together,

Now it is fine, I use just 4 games in the database.

Now every game is different (90%)

Thank you guys for the help.

Tobias

[Tobias]

Hello,

I have another question, what es the maximum for books on the DGT Pi.

What filename can I use when the alphabet is full? (example z-spanishgame.bin)

regards Tobias

[Scally]

Hi Tobias,

You can call them what you want, some are huge.

[Tobias]

Thank you!

Is it possible that I can an completely picochess backup from the sd card?

[mvanthoor]

You can use Win32 Disk Imager for that. You can have it read the SD-card (in a card reader) and dump the contents to the hard drive.

The Image I'm building has the GUI and the SD copier in it. This will allow someone to use just connect a card reader to the RPi, log in over the network, and copy the card directly. Then the partitions on the copied card can be shrunk using GPARTED, and with dd, a dump can be made back onto the original card, in the home directory. It can then be downloaded from another computer. That will create a MUCH smaller image than the one Disk Imager will create.

At some point after I finish this image, I'll also write a short how-to on creating such an image. For now, as a backup, dumping the image using Win32 Disk Imager will work.

[Tobias]

Now I have a problem, my books are not working after renaming and deleting the standard books.

Just my first book "Koenigsgambit" is fine.

Thats the books.ini:

[a-nobook.bin]

small = nobook

medium = No book

large = No book

[b-koenigsgambit.bin]

small = Koenigsgambit

medium = Koenigsgambit

large = Koenigsgambit

[c-wienerpartie.bin]

small = WienerPartie

medium = Wiener Partie

large = Wiener Partie

[d-laeuferspiel.bin]

small = Laeuferspiel

medium = Laeuferspiel

large = Laeuferspiel

[e-centrepartie.bin]

small = CentrePartie

medium = Centre Partie

large = Centre Partie

[f-italienisch.bin]

small = Italienisch

medium = Italienisch

large = Italienisch

[g-vierspringer.bin]

small = Vierspringerspiel

medium = Vierspringerspiel

large = Vierspringerspiel

[h-zweispringer.bin]

small = Zweispringerspiel

medium = Zweispringerspiel

large = Zweispringerspiel

[i-schottisch.bin]

small = Schottisch

medium = Schottisch

large = Schottisch

Have you a idea?

regards

[Tobias]

Now I have reloaded the backup it is ok.

Why I cant delete the standard books?

[RandyR]

Tobias,

Small, medium and large refer to the number of characters displayed on the clock/display. The limits are as follows:

small - 6 characters

medium - 8 characters

large - 11 characters

For example, you could use:

[b-koenigsgambit.bin]

small = KngsGb

medium = KoengGbt

large = Koenigs Gbt  <<--------- spaces are counted

The same limitation exists in the engines.ini file. You need to be creative when shortening the names.

Randy

[mvanthoor]

You beat me to the punch with this one Randy :)

If PicoChess actually DOES ignore books if the names are too long, I'd look into changing this. Just read the name, and if it's longer than the one that'll fit on the clock, just cut the name off at the right amount of characters. In that case, the book will at least work. (Maybe I should start keeping a todo list.)

I would actually suggest:

short=KGmbt

medium=KGambit

long=KGambit

(Experiment if lower or upper case letters work best... don't know yet. I have an XL clock lying around from before I switched to the 3000LE. I'll hook that up for testing. I can't test the long names, but I assume if a upper/lowercase letter works best on the normal DGT3000, it'll also work best on the Pi. Might be different on the RevII, though.)

Or, have a scrolling display so no truncation would be required.

Yes, you better make a list. :^)

Tobias,

We’re you successfully able to add multiple books to your DGT Pi?

I am interested in creating my own books using chessbase 16 but I am not really sure where to start

Thanks

Sigi

[Scally]

Hi Sigi,

The books files have to be in .bin format for Picochess and added to /opt/picochess/books 

You can then build the books.ini file used by Picochess to select the books by typing:

cd /opt/picochess

sudo python3 ./build/books.py

You can then edit this file manually if you like to tidy the names up to fit your size of clock display properly.

Mine are shown in the attachment below.

The reason we don’t include extra books in the Picochess GitHub site is that some are very large, too large for GitHub upload.

These would also increase the size of any images provided, like the those from Randy.

But you can readily search and add your own as I’ve already described.

It’s the same with Syzygy Endgame tablebases, Picochess has 3&4 men tablebases as standard (4.3mb) , I have 3-4-5 (939 mb), however should you want 6 or 7 men TB’s they are 150gb & 17 terabytes accordingly.

Cheers,

Al

[Sigifredo Franco]

Al,

Thank you for the response. I have several questions. I do not have any experience with creating these files. can we take this offline? My email is s1970....@gmail.com.

[Sigifredo Franco]

Al,

I have a few question. I was able to successfully create and upload opening books following instructions from Benny Topschach website dated 2018 :)

My first question is can you confirm that the latest Version of Pichochess is .9L? I saw this on DGT website but there is no time stamp.

Do you know how to change the weight of the moves to zero? I have created several books in .bin format as white against  blacks most common defenses.

[Scally]

Hi Sigi,

I sent you an email a couple of weeks back.

I’ll try to answer your question as diplomatically as I can, hopefully it is not misunderstood as I don’t want to offend anyone:

Picochess v0.9l was released back in December 2017 and was included with the introduction of the DGT Pi. Since then, v0.9m & v0.9n were released by Jürgen on the official GitHub site: https://github.com/jromang/picochess/releases 

Jürgen went on to release v0.9p through to v0.9u privately here: https://picochess.com/

Dirk then updated to v1.0, v2.0, v2.01 and lately v3.0 “for his own use” here: https://github.com/tosca07/picochess/releases

Randy has the latest v3.0 images hosted here: https://groups.google.com/g/picochess/c/jCuWSm0EDH8/m/50v2L-xbAwAJ

There’s plenty of other interesting material in the forum of other projects that various people are doing.

As for changing the weight of the moves to zero in the .bin book files, I have no idea. I personally use a lot more book files than are available on the Picochess GitHub sites, but can’t host these because of the sheer size of some of them.

Maybe someone else here can help you with your query?

Are you able to share any of your book files?

My list is attached.

Cheers,

Al.

[Sigifredo Franco]

Al,

Sorry for the late response.

Also I accidentally sent you two emails last week. I was having issues with my email.

i have decided not to attempt to change the weights of the moves.

I thought that this was needed but it turns out that i have many files created.

Basically, i created a file for each defense. I believe that i creaded close to 30 files.

 Which version of the pichochess would you recommend. I built the opening books so that i can practice against the engines. For example, i have all major lines that start of 1 e4 e6 2 d4 d5.

The idea is to try different lines as white ( 3Nd2, 3Nc3 , 3 e5) to see which major branch i like the most.

thanks

Sigi

Hi Sigi,

That’s a no brainer, it has to be Dirk’s superb v3.0 with all the extra features.

You can download either the desktop or lite versions at the bottom of Randy’s thread here: https://groups.google.com/g/picochess/c/jCuWSm0EDH8

Cheers,

Al.
