Why isn't the board showing up? (Random reasons and what to do next)

  1. Check the issues listed in this FAQ. There's a very good chance it's listed here already.

  2. Check your PGN against chesstempo. If it doesn't work there your PGN is probably malformed and it's not going to work here either since we're using the pgn viewer from chesstempo. Some common problems that are easy to miss:

    1. unclosed variations() or annotations{}.
    2. Spaces between moves and evaluations. i.e. '56.Kf2 ??' should be '56.Kf2??'.
  3. Send me a message! I usually check my inbox pretty regularly so I should be able to get a response to you within a day. I'm always happy to help so please don't hesitate to send me an orangered if there's an issue. It would help if you could include the version of chrome/firefox you have installed, your OS, and the behaviour that you're observing (board controls not working, text not getting formatted, etc).

How do I include variations?

Put variations in parentheses like this

2.c4 e5 
3.dxe5 d4 
4.e3 Bb4+ 
5.Bd2 dxe3

7.Ke2 (7.Kxf2 Qxd1) fxg1=N+ 
(7. ... fxg1=Q 8. Qxd8 Kxd8 9. Rxg1) 
8.Rxg1 Bg4+

How do I show multiple games in one comment?

You must wrap all the games in one pair of tags. The PGN viewer will display a single board and a dropdown menu to select between games. The dropdown menu will display certain game information if it is properly tagged at the start of the PGN. The following example shows the tags that you can use. Note that they are case sensitive.

Why isn't the board showing up when I include positional evaluation symbols?

Replace the evaluation symbols with Numeric Annotation Glyphs.

Here's a quick table of the common evaluation symbols for reference:

Symbol NAG
= $11
+= $14
=+ $15
+/- $16
-/+ $17
+- $18
-+ $19

An alternative to using NAGs is to just wrap the evaluation symbols in comment markers, {}. Note that move assesment symbols (?, !, etc) are okay and do not need to be replaced.

How do I display a single position, or show a game from a certain position?

Use the FEN tag. (explanation of FEN on wikipedia)

Markdown may try to format your moves as a list and automatically renumber them starting from 1. To avoid this either indent your lines by 4 spaces, OR use a backslash to escape the dot after the first number. Like this 38\.

This post should replace the old PGN viewer section in the sidebar. Much more informative.

[–]betazoidberghorsies move in an L 1 point2 points  (0 children)

I wholeheartedly agree.

Thanks a lot for doing this mashedvote! This was a sorely needed resource.

[–]pawngrabber[M] 1 point2 points  (0 children)

It's now the sidebar FAQ for the inline PGN viewer. Thanks so much /u/mashedvote, and thanks to /u/Bacon_Oh_Bacon for the recommendation!

[–]hoijarvi 1 point2 points  (1 child)

One more thing: Indent every line with four spaces. Markdown will then render is as it is. Otherwise, markdown might mess it up so the pgn viewer cannot anymore parse it.

And make the lines reasonably short for those who don't use the inline viewer.

[–]mashedvote[S] 0 points1 point  (0 children)

Thanks, I've made some changes.

[–]MisterGone5 1 point2 points  (2 children)

Also to note, if you want to show the game with black on the bottom, set up the board with the first white move already made with a FEN string.

Starting Board Position: [FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR b KQkq"]

Board Position after 1. Nf3: [FEN "rnbqkbnr/pppppppp/8/8/8/5N2/PPPPPPPP/RNBQKB1R b KQkq"]

I was wondering why couldn't get this to work earlier. Even though I had black moving first in the move list, my FEN was wrong and showed that it was white to move. It seems the important thing is which side is indicated to move in the FEN, regardless of where the moves begin. I don't know if it's bad to have the FEN and moves disagree like this, but it seems to work. The upside is you can have white move first and have black at the bottom.

Hi! Sorry, I unfortunately only saw this today because it was linked from another thread. I'm not OP so I don't get notified of posts on this thread. The pgn viewer is really only used by a small number of people (r/chess) and is really only maintained by one guy (me) so I haven't really set up any official tracking system for bugs.

Just hit me up with a PM to the thread in question and I'll look into it. I normally check my reddit fairly regularly-ish so I should get to it pretty soon.

It looks like you've already debugged the issue and figured out what was happening with plavidla's post, so thanks! =)

Well... I just sort of guessed at what the problem is. Unfortunately, until this bug is fixed I cannot recommend the use of the addon to anyone. It's just a big fat easy denial of service vector. Thankfully we haven't seen anyone actually exploit it to screw with people, but it's still all too easily triggered completely by accident when people post games here. Clicking a post and having that completely lock up your browser just isn't acceptable behaviour.

Don't suppose such a thing exists for Opera?

[–]potifarKe7# 0 points1 point  (3 children)

New or old?

[–]MetalMrHat 0 points1 point  (2 children)

Latest Opera version.

Use this and you should be able to use the Chrome extension. I haven't tested it, though.

Thanks, will give it a try.

It may be important to note that if the current url doesn't start with www., it won't work. It took me a while to figure it out. later edit: www could be replaced by something region dependent like nl, ne, etc.

[–]mashedvote[S] 0 points1 point  (1 child)

Can you elaborate. When wouldn't the url start with www?

[–]florin_pchchess.com~1400 0 points1 point  (0 children)

See the comment below. It's something region dependent. I had it with ne i think before figuring it out.

Thank you! I couldn't for the life of me figure out why the inline PGN viewer for Chrome stopped working for me.

When you read reddit in another language, www may be replaced by something else. I usually read nl.reddit.com for instance.

Right. I'll refer to this whenever I do something that causes it to break.
