Olga Chess Viewer Quickstart

To try out Olga 2 (new name coming).
https://protozefoss.github.io/

Olga Chess Viewer
Written and developed by Christopher Dean
Copyright (c) 2017 Chessgames Services LLC

*** Known Issues ***

• 3 Move repetition reports for the rest of the game
http://github.com/jhlywa/chess.js/i...

• Piece animation "wiggles" when landing on a destination square, on some platforms in some circumstances.

• No way to alter the speed of "autoplay" mode from mobile phones or tablets. (Desktops can press 1-9, or 0 for lightning-mode.)

• Copying and pasting the game score strips out the spaces (e.g. 1.e4e52.Nf3Nc63.Bb5 etc.) Workaround for now: use the "View PGN" feature and copy straight from the ASCII text.

• Olga chokes on PGN that does not include "x" for captures, e.g. ed5 instead of exd5.

• Olga chokes on odds games which technically do not start on move #1 (e.g. pawn and move)

Olga Viewer: Congrats to the CG team for getting over to the new aerver! I had hoped that meant the site had also been moved from perl but I understand how much work that will be. If you do manage to get it migrated, it will be much easier to find developers to work on it. Still hopeful for ...

  OhioChessFan: This game shows up as 29 moves in Olga, and 47 moves in every other viewer:

I would like to ask you to pin the link to the UI https://protozefoss.github.io/ here in your forum header and post it in the Kibitzer Cafe from time to time (if you like). The forum section of CG is a bit 'hidden' and most members will not check here too often.

Maybe with a small intro, so it will be easier to follow things for members who are late to the party. Also you could post the link 1x into twitch chat for the VODs.

For viewers:

  Olga Viewer: Thanks <login> for the feedback and links you have shared. I did not mean to take over the design discussion with Magic the gathering. But I was getting bored with no one to chat with :(

I will try to keep the videos more focused and likely shorter.

Anyone wanting to check out the past videos - Know they will start to disappear this coming Wednesday.

I never did get the FEN to work as I moved on to other things needing work.

  Olga Viewer: There was no stream this week - Next week I am aiming for release candidate 1! I will be talking more about that on Wednesday.

For now please give the new features a test and provide some feedback. <https://protozefoss.github.io/>

New Features:
**Persistent storage of Olga 2 colors (cookie)

**More colors for themes and game score size slider (this has issues at the moment).

** New layout work on mobile (Portrait has a new "side by side" technique for the header).

** Improvements to header data display

**Multiple Games support for "Sets" which will be a way to share entire game sets with a unique name and date (set creation date).

** Oh did I say support for Chess960 games? Come see them, they are games 3-6 I believe.

The games being tested can be found
RAW PGN (sort of):
https://raw.githubusercontent.com/P...>

Game Sources:
<https://github.com/ProtozeFOSS/Olga...>

To change games look for the arrows at the top right of the header.

<Stephen> is already looking at this, but <Olga> failed to display the correct start position on the FEN from this odds game I recently uploaded- so far it is the only odds game I uploaded in which <Olga> failed to display the correct start position.

The ChessTempo pgn viewer was able to display the correct start position.

This game here: H Halsky vs H K E Clemenz, 1862

  Olga Viewer: <jessicafischerqueen> Thank you for the heads up. Yes, I believe Stephen is already got an update to chess.js and a patch to Olga 1 he is testing.

Just to confirm, this game did work in Olga 2. You can test PGN in Olga 2 (if interested) by:

1. Open Olga 2 <https://protozefoss.github.io/>

2. Click the settings icon (bottom right of the game score)

3. Navigate to the "PGN Edit" tab - top right, of the menu tabs (you might need to use the arrow key to go right if you have a low resolution or portrait display).

4. Paste in the desired games(s)

5. Click the "Set PGN" button on the bottom right.

You can test multiple games ("Sets"), just insert each PGN with a newline between them.

You can name and date the set by adding a "Set" and a "SetDate" property into the PGN (at the top is preferred). This is how it looks for the current game set on the test page.

[SetDate "Halloween 2020"]

Not sure if it's a known issue, but when I downsize the board slightly using the slider, the move forwards/backwards arrowed buttons no longer work as a means of navigating the score.

Thank you sir, that sounds like good news on the <Olga 2>.

The bug search in beta testing must be exhausting, I imagine...

Nov-04-20
Premium Chessgames Member
  Olga Viewer: Absolutely. The biggest issue is all the new features, all time. "Tabled" score format coming today, I'm very excited to show everyone!

  Stonehenge: White moved twice here to start the game.

(1. e4 ... 2. d4 e6 etc.)

A Ehrmann vs Morphy, 1859

Dec-03-20  Z4all: RE: <Two Move>, <Pawn and Two Moves>, games, etc...

Can we please "get modern" and store these games as they were intended to be played, i.e. with a <null move (-)>.

That way we avoid FEN hacking, and allow the movelists to match the source.

SCID, Fritz, Chessbase(? - pretty sure thou), all allow it.

<CG> should allow "-", and Olga should too.

Dec-03-20
Premium Chessgames Member
  Olga Viewer: <Z> Olga 2 supports null moves :) Also, this odd game with white moving twice is supported as well. (IMO) The site should invest its time into making Olga 2 a first-class PGN Viewer.

A lot of work needs to be done on the server-side to realize something as good as "Fritz".

🤔 Also, it is not fair to compare a commercial system with multiple developers and real money to the hobby project that Olga + CG is.

Dec-03-20  Z4all: <OV> any chance of you (or someone else) trying to upload a game on <CG> which has null moves?

Aside- pgn4web also supports null moves, fwiw.

Correction- I should have denoted the null move with the double dash <--> instead of a single dash in my previous post.

* * * * *

<A lot of work needs to be done on the server-side to realize something as good as "Fritz".>

I think I agree, though exactly what is "good" is always subject to debate.

I've always thought <CG> could be "better" than "good", but only after it's as "good" as "good". Ah, there's the rub.

* * * * *

<Also, it is not fair to compare a commercial system with multiple developers and real money to the hobby project that Olga + CG is.>

Sure, but some projects, like Linux, seem to match up pretty well against the commercial systems.

I could say more, but let me finish off with the top link on google for <Olga2>:

Dec-18-20  Z4all: Hi <Olga>,

Can I please make a request?

On the movelist below the display board, could you append the game result?

I'll just assume Olga 2 already does this, but could we retrofit Olga 1 to do the same?

Thanks for your consideration, and regards,

--Z

  Olga Viewer: I could easily add it to the flow score on the current codebase. I'm not sure if Olga will receive the fix but it's a possibility.
Dec-19-20  Z4all: Thanks for the consideration <Olga Viewer>, but I think I was mistaken - it's <pgn4web> that's not showing the result. I think <Olga> v1 already does.

Sorry for the mixup.

Jan-01-21  mmmjv: Why is there a forum for the olga viewer which I have no trouble getting but not one for the chess viewer deluxe which I can not get? I tried the FAQ section here and it sends me to a page that tells me I can't use their java on my Chrome browser because

We have detected you are using Google Chrome and might be unable to use the Java plugin from this browser. Starting with Version 42 (released April 2015), Chrome has disabled the standard way in which browsers support plugins.

And I can't use it on my Firefox because

We have detected you are using the 64-bit version of Firefox which will not run the Java plugin from this browser.

The Firefox I just downloaded about 20 minutes ago just for this reason.

Didn't Java used to be something that was just there? I have used it before on this site in the past. I've had no problem getting the chess viewer deluxe board but now I can't.

  g15713: When doing analysis, how does one tell Olga to underpromote?
Jul-01-21  Boomie: <Olga Viewer>

About 2 years ago, I pointed out that Olga could not handle under promotion. Periodically I have reminded you about this obvious oversight. Not only has there not been any change made, my comments have not even warranted a response.

Why doesn't CG just buy a Deluxe capable board? Why are you trying to reinvent the wheel?

Jul-02-21
Premium Chessgames Member
  Paint My Dragon: <Olga Viewer>

I think Boomie makes a good point. Olga development seems to floundering badly.

The problem that I mentioned above about the sizing slider disabling the navigation buttons resulted in you removing the slider, which was presumably the easiest fix. But now the board is larger than my screen even on the small setting, with no means of downsizing it.

Jul-02-21  Z truth 000000001: One problem with <Olga (2)> is that she's been orphaned, as it seems <CG> has decided to move on to a new viewer - Aria.

User: Olga Man

The developer seems to have soured on working on Olga (2):

chessgames.com chessforum (kibitz #35121) (see, also, CIO's reply just after)

Unfortunately I forget the developer's name, which would be useful for looking up posts concerning development.

(Actually, it would be nice if the development efforts were better documented on this page - the new name just confuses things:

https://protozefoss.github.io/

is really for Aria, not Olga 2 ("new name coming" in profile above is out of date).)

What viewer does Aria, in the preference dropdown list, actually use? Not the beta viewer from protozefoss.

Who, if anyone, is responsible for maintaining/fixing Olga 2?

* * * * *

For the record, Chris was the original Olga developer:

chessgames.com chessforum (kibitz #32291)

Christopher Dean, to be exact: Olga Chess Viewer Quickstart (cf. Credits)

Maybe he's the one doing Aria?
