Chess.com doesn't like my PGN

So I have a blog at http://www.chess.com/blog/DamselinDischess where I analyze GM games.  I do the analysis in Chessbase, I save it as a PGN, and I paste the PGN into the Chessbase blog using the "Insert chess game or diagram" tool.  I have never had a problem until the latest game today.  

Today I tried pasting in a PGN and got an error saying "Improper PGN."  The PGN viewer here:  

https://ingram-braun.net/public/chess/online-pgn-viewer/'

Has no problem with it.  Chess.com has had no problem with my PGN files before.  They customarily contain a great deal of detailed analysis and commentary.  

Has something changed or what is going on?  Why am I having this issue and what can I do to solve it?

Thank you for any help.  Here is the PGN I'm trying to use.

stiffer resistance for black by moving the knight offsides and putting the
queen on b2. Unlike the knight, the queen cannot make immediate use of that c4
square. Black is not so much improving his own position as making it difficult
for white to improve his position.}) 19. Nxb2 Qd7 20. Nc4 {Putting the knight
on square like this is in keeping with general principles. But it also serves
a concrete good. The d6 pawn is a potential weakness. In addition, white might
play something like Na5 at some point to target the b-pawn, which will have
difficulty advancing to get out of the line of fire. For example:} Rf7 {

he was thinking, but it bears noting that the move grabs control of additional

advance on the queen side.} Raf8 22. Qd3 ({Huebner questions} 22. Nb5 dxc5 23.

All I did was delete the fields in brackets at the top starting with [Annotatir "Angie"] Then backspaced the beginning of the number 1. d4 Nf6 so that they were directly under the last field in your header bracketed fields and the reason is because the fields I see going in to the pgn editor on here don't include things like [Annotator] or [Source Code]. I probably did not have to delete the [ECO ] field bilut I did because I noticed when I input my PGN files I always have to re-fill in the ECO (which I would have done had I jotted it down..I just didn't remember it as I was inputting. I also noticed that when I pasted your posted text into the pgn editor that the very top left first bracket had been missed possibly by me or some copy paste glitch) but I knrlew the first field of the PGN always starts with a bracket so I added it when I saw it missing. I would try to do the same thing as I did just now Angie and then fill in the blanks (like the ECO that you see available to fill in the individual. Section once you have pasted the text into this sites pgn editor. Then..It's up to you but I often add that I Analyzed and Annotated a game in the [Events ] field - If you want since at least I know that always works fine) -- for example, Fischer vs Spassky World Championship Match Annotated/Analyzed by Angie] sort of thing or in one of the other fields if you want as long as there is a Bracket [ to start it and bracket ] to finish the field. It's a very cool Annotation Angie! Great work and I hope this helps 💕💗

One more thing, I believe the reason this pgn works on other sites and not here is that there are actually different types of pgn files (I am not totally sure of this but I believe that is the case. The point of this is that as long as you keep the fields simple before you input the pgn it itself (or just after you pasted it in the pgn box (where you paste it) then just before you hit continue you can scroll around the pgn to the top and bottom looking for non-conforming pgn area (like a missing bracket or a field that normally is not in a simple pgn file like [Annotator] or [Source Code by] ..The other standard fields like [Event] are part of the usual pgn file but those other fields I believe are why you were having problems pasting in the file..then trying to edit or just post it. As soon as you paste the text into the pgn box, I would scroll around looking for those things I mentioned. Then when you click continue all of that text will immediately appear in the next editing window..If nothing appears then go back and check the file again for those things (especially the very first bracket [ which I noticed sometimes doesn't get grabbed when we thought we had it) and so forth, Then when you click continue all of your text should immediately appear and as you check all of the available editing tools and I usually like to use the focus feature on many games then just click in the next >> tab..You will be able to manually enter data like your name and the ECO code into those fields and edit them as desired. In the last field that you come to there is an option o the far top right to "Show Coordinate s" which I constantly forget to check as the default setting is not to show them so you will need to check that box at the last minute and select the color nd style of the pieces and board you want. If you take over twenty minutes to do these things as  have in the past when I first started out the post may time out in effect so nothing will show because of the extended waiting period expiring before you hit save/preview and so forth. I hope this was helpful. Let me know if you have any other problems with posting your very cool pgn files 💕💗

Oh..I just noticed that pasted pgn file of mine works properly but runs out at move 12. This may be a memory/space capacity area for the editor tool itself but I have feeling it was more a case of my little handheld Android not having the total capacity to hold the huge amount of data in the pgn file. If you use a desktop or similar it should all go in and paste to the final move despit it being a very large pgn file compared to most that I've seen, All though many are very large files as yours so it really should work with the full capacity. Good luck 💗💕

These brackets (  ) are for variations of moves to my knowledge wher these { } brackets are normally for text. I know where we start a move or variation with ( then it must be closed with ) and not closed with } and the usual format I see it something like ( 12.e5 Nf6 {text is written possibly here but must be closed with the following bracket}) Notice that where there is a ( move bracket then you can have text in the { } brackets but then it will cause a glitch if the final move bracket )  has not re-closed the move and the text..so it is possible as well that a bracket is not in place where it should be following those types of programming rules. I wish I was an expert on pgn formatting but I'm not, I know a little from here and there. See if you spit anything and I will look at that area again where it got cut off either because my Android clip board copy capacity or possibly because a bracket is not placed accurately right where it cuts off. Take care. 💕💗

13. Nd4 Re8 {Covering the e7
square to prevent ideas like} (13... -- 14. Nd5 {and} -- 15. Ne7+) 14. f3 Nc6
15. Nc2 ({Fritz suggests} 15. Nxc6

 I'm not an expert on pgn data but what it looks like to me at move 13..  -

See the two dashes --   That is a symbol to my knowledge of a null (empty) move that someone accidently inserted is what it looks like to me...as if maybe a move belongs there that was going to be inserted later but never was or the move somehow got deleted as pgn files are known to be very unstable creatures unfortunately. This is why they have pgn file cleaning utilities which we use to clean all of our pgn files of containing any variations or text annotations before we actually create a database of pgn chess game files. Those types of mass pgn game files are intentionally clean pgn files and they are both supposed to contain any text annotations or even variations since they can and iften have become unstable in chess pgn databases. I was recently checking out a YouTube video where a guy demonstrates how to create or edit on opening book file for his computer engine. I was researching the book.bin file at the time trying to figure out why thry selected a third choice (not even based on a highest evaluated continuation) variation of one of the Scotch openings and then I realized I could actually edit that book.bin file as desired to have the engine play the more accurate opening variations as well and so forth and that is where the gentleman reminded me of why we clean the pgn files before filling them all into a mass storage area together. I would recommend you back up all of your annotated files in a separate area somewhere and that you keep your annotated games like that one together but separated so that only your annited games are in a custom single database as they are the most unstable because they contain so many variations and text notations and so forth. I would have that group of files all backed up separately somewhere else for safe keeping in the event one of your annotated PGN files with variations becomes unstable in the future do you can delete the bad file and paste a fresh copy of it back where it was in a separate database made just for your annotated games. I hope all of my silly bantering helps. 💕💗

Noted

It is a glitch in the annotation between moves 12 and 13. All I did was delete the small annotation that contains the --  -- those null (missing) moves. Now, The whole file plays and it has nothing to do with the file size as I just did this with the clipboard of pasting to my little Android. If I knew what those moves were supposed to be I could insert them in the text before I actually use this sites pgn editor to convert the text into a on file. I once again deleted the [Annotator] and remaining feilds below it -- Well, Here it is still in my clipboard so you can check the difference from your original copy above:

I simply typed in the E62 as the ECO and I noticed the players ranks are missing as this seems not to want to paste with my files either so I often jot those few items down and then once I'm editing the pgn file I just type them in the corresponding fields using this sites pgn editor. I hope this helps 💕💗 Take care :)

Yikes! It only pasted up to move 15 now :( What a pain :( ...I will have to scan in that area now as time allows but the file is not completely incompatible as you can see. It's just a matter of finding the problem areas in the file as I don't recognize some of that formatting in the pgn files that I've studied and created over the years. Take care. 💕

See, The file is missing moves where ever you see the double dashes -- anywhere -- those are supposed to have moves in those spots as you will notice the last pgn which I edited went further but then stopped at this point where there is a null (missing) move:

15. Nd2 a5 (15... f5 16. f3 -- 17. Nb3 {

is Heubner's analysis. He views it as squashing black's counterplay. I see no

improvement compared to my analysis.}) 16. a3 {This seems to be one of those

After 16.f3 there is a --    which means a move should be typed in there as well as in some other areas of this pgn file Angie - That's what's going on with it -- the null (missing) moves must be filled in with what you want those moves to be 💕💗

The main problem appears to be that null moves are not currently supported in the PGN with the viewer. I'm not sure if this has always been or is a change. There may possibly be other issues, but this is the first that I was able to verify with a test. Have your previous pgn's ever had null moves in them as in this case? (I also frequently use null moves in pgn's as it's a great way for example to convey a threat in the position.) You can report this issue and request that the null moves be allowed by sending a message here: https://support.chess.com/customer/portal/emails/new

Thanks, and I hope this helps.

Agreed. You could also just fill in those null  --  moves with actual moves (for example, with moves your engine says are good) to make the examples of threats or simple variations more clear in the meantime ❤
