Banksia GUI released

Hi Pham!

Now I'm testing BSG book openings features.

Is there a way to slowdown moves played during Polyglot / PGN openings instead of instantly reaching the position in middle game? What is the meaning of auto-play opening check/uncheck?

Best regards, Alex

All ok until now with tournament features

Hi Pham!

Best regards, Alex

Thank you for the info!!!

PGN, EPD openings can be used for tournaments only. For tournament games, BSG will create the last positions (from EPD) or ready-all moves from PGN, Polyglot books and games start immediately from those middle positions.

Normal games (not tournament ones) can use only Polyglot books and two sides can play move by move follow books. If a side is an engine, BSG will make that move for that side if the user ticked on the that "Auto-play" checkbox. For the human side, BSG won't make moves, but display all opening moves in Book/EGTB panel and as bubbles (with scores) thus users can decide themselves.

We can't slow down book moves since one of the main benefits (save time) of getting hits. However, you can set both sides as human and play each move as long as you want. BSG also provides some way to study such as the panel/bubbles mentioned above, book-viewer to view/edit a book as a tree...

I wonder if there is a way to copy the cross table of a tournament.

If you mean about a "pure" crosstable, yes, on the panel Tourmanet Result, there is a tab "Plain text" to copy all stats, including the crosstable. If you need an image, use the button on the top-right corner to copy it.

I made a tournament between stockfish depth 5,depth 6.depth 7,depth 8,depth 9

Results are:
Depth 9:7.5
Depth 8:6.5
Depth 7:3.5
Depth 6:2
Depth 5:0.5

Now I would like to add participants to the tournament when every new participant is going to play all previous participants twice with white and black so later I can get a new cross table and I wonder if it is possible to do it.

I basically duplicated stockfish 5 times to make the tournament and used 5 different time id.

I guess that I can make a gauntlet but I do not see how I can have 6 different time controls so I can only make a gauntlet of Stockfish depth 10 against 4 players out of 5.

There are some ways to do that.
- The simplest way is to create a new tournament with new games you want to add ("add participants to the tournament when..."). After all new games are played, you can merge the new one with the old/existent one, using the function Edit tournament (menu -> Tournament -> Actions -> Edit current tournament), thus you can have two data in one for Elo calculating/crosstable
- Create a new tournament with the new games as you want (similar above solution) but you export all games into PGN files. I am sure we all are family with PGN files . Now, you can merge and edit them as you want. BSG can help to calculate Elo/create crosstable directly from PGN files (below illustration)
- If you are good at JSON, you can edit directly the file banksiaplaying.json. All information about the tournament's games is stored in that file. JSON is the human-readable format, both software and human can work directly.

For reference, why I think polyglot moves should be played by weight:

Cfish implementation: https://github.com/syzygy1/Cfish/blob/m ... polybook.c

If I understand the C code correctly, the first move with the highest weight is played as the best move.

lichess-bot implementation: https://github.com/ShailChoksi/lichess- ... ot.py#L372

If "best_move" is set, reader.find() is used from python-chess. And reader.find() is defined like this:
https://python-chess.readthedocs.io/en/ ... eader.find

"Finds the main entry for the given position or Zobrist hash.

The main entry is the (first) entry with the highest weight.

By default, entries with weight 0 are excluded. This is a common way to delete entries from an opening book without compacting it."

Options with the prefix UCI_ are special ones. They require chess GUIs understanding and doing some specific things to support. If chess GUIs don't support (quote from UCI protocol document):

Code: Select all

If the GUI get an unknown Option with the prefix "UCI_", it should just ignore it and not display it in the engine's options dialog.

So far, BSG supports the below UCI_-prefix options:

Code: Select all

uci_infojson, uci_showwdl, uci_wdlinfo, uci_limitstrength, uci_elo, uci_chess960, uci_variant, uci_showmovesleft

I don't know about those options (UCI_ShowCurrLine, UCI_EngineAbout) either. I may support them if you describe what they are, their purposes, what specific actions you expect from GUIs to support them.

Dear Pham,

Ok, I tried with one of the suggested values and it works. So no issue, it functions according to specs.
UCI_Variant is not really "standard". It seems the big names are leading the pack here.
BTW: I found some reference on the internet which is comprehensive about the UCI_Variant implementation. https://python-chess.readthedocs.io/en/ ... riant.html.

From the UCI specification:

* currline <cpunr> <move1> ... <movei>
this is the current line the engine is calculating. <cpunr> is the number of the cpu if
the engine is running on more than one cpu. <cpunr> = 1,2,3....
if the engine is just using one cpu, <cpunr> can be omitted.
If <cpunr> is greater than 1, always send all k lines in k strings together.
The engine should only send this if the option "UCI_ShowCurrLine" is set to true.

The UCI_EngineAbout has no added value. I just implemented it when I normalised the name of my program (when I added the xboard feature myname option). From the UCI specification:

* <id> = UCI_EngineAbout, type string
With this command, the engine tells the GUI information about itself, for example a license text,
usually it doesn't make sense that the GUI changes this text with the setoption command.
Example:
"option name UCI_EngineAbout type string default Shredder by Stefan Meyer-Kahlen, see www.shredderchess.com"

Yves De Billoëz,

UCI_EngineAbout has been supported for the next release.

I am still confused about what the engine could print out if its option UCI_ShowCurrLine on. If only info with terms "curmove", "currmovenumber" (as Stockfish has been doing), BSG has supported already.

Hi Pham,
when creating a multi engine what is the difference between "highest vote" and "highest score" ?

cheers

The version of Belofte you are using is a special build I made for testing some new features. It has not been released yet. I am still working on 2.1.4 and will only release it if next to the UI changes, I gain at least some elo. I have been busy professionally lately so development is going at a slower pace now.

Would be very nice if BSG could use online Syzygy tablebases up to 7 man
