Re: Posting chess games, positions and variations

Put a header in the following format at the front of your PGN file -

[Event "FIDE WWC"]
[Site "Lviv"]
[Date "2016.03.06"]
[Round "1.4"]
[White "Hou, Y."]
[Black "Muzychuk, M."]
[Result "1/2-1/2"]
[ECO "C83"]
[WhiteElo "2667"]
[BlackElo "2563"]
[PlyCount "0"]

When the file with the header is enclosed in the tags and posted it appears thus -



NB: PlyCount should be equal to the number of half-moves in the file.

Thanks, John. I have previewed what's below and think it will be OK. I am pleased to see the play-through arrows below the board. My next practice will be to post a position (not the whole game) but with continuation moves from that point.

Getting there, but my copied game from my ChessBase included details like our respective teams but these have not appeared. I suppose the question mark below the date is for the venue?

Yes, Paul, the ? is generated from Site, Lviv - the venue - in the example below, in the header. If you compare the header and the output generated from it by the PGN viewer you can see that ECO and White/BlackElo do not generate anything at all in the viewer. So, if you want to display them just add the figure after the players' names as I have done, below. The ECO code could similarly be added in Site before/after the name of the venue.

[Event "FIDE WWC"]
[Site "(C83) Lviv"]
[Date "2016.03.06"]
[Round "1.4"]
[White "Hou, Y. (2667)"]
[Black "Muzychuk, M. (2563)"]
[Result "1/2-1/2"]
[ECO "C83"]
[WhiteElo "2667"]
[BlackElo "2563"]
[Annotator "JM"]
[PlyCount "42"]



If you want to include annotation by hand the limited example below points the way. Usually people use a programme such as Chessbase to do all that and then they generate their PGN file with the annotated game(s) in it. The header(s) of the game(s) in that Chessbase output PGN file can then be edited as I showed, above, then the file can be posted here inside the PGN tags.

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5 Be6 9. c3 (9. Be3 Be7 {Game 2}) 9... Be7 10. Bc2 Bg4 $5 (10... Nc5) 11. h3 (11. Bf4 $5) 11... Bh5 12. g4 Bg6 13.

Looks like these two lines are wrong:

[White "Habershon, Paul F ["MK Phoenix 1"]
[Black "Klingher, D. [Barbican Youth"]

Try:

[White "Habershon, Paul F (MK Phoenix 1)"]
[Black "Klingher, D. (Barbican Youth)"]

So did that error invalidate the rest of the header details, so that the players' names etc. did not appear by the diagram?
At least I got the textual annotation to appear.

You have to enclose both the header and the game with the pgn tags. I don't think italics will work inside the pgn tags.

Thanks for all the help so far with posting games and positions. I am a slow learner but I think I am getting better. How about this? For practice I took an extract from that 1966 book 'Chess Treasury of the Air' in which Harry Golombek reveals his 'gravest error'.

You can either post full games or a position.

For full games (with or without annotations) get from your software the PGN export of the games and enclose those in this tag:

Code: Select all

[pgn] ... [/pgn]
For a position, get from your software the FEN string and enclose that in this tag:

Code: Select all

[pos] ... [/pos]
Notes:
- all chess software should be able to export games in PGN format and position as FEN strings; if you don't know how then refer to the manual/help of your chess software
- if you post games or a position following these instructions and the square A8 on the resulting chessboard is flashing, this means your PGN text or your FEN string is incorrect and needs fixing (you might click square A8 for more info)

For more info about the PGN format: http://en.wikipedia.org/wiki/Portable_Game_Notation
For more info about FEN strings: http://en.wikipedia.org/wiki/Forsyth%E2 ... s_Notation
Looks like we have always done POS wrong - oh dear :cry:

This code instead gives you the final position of Aronian's game:

Code: Select all

[pos]8/5Rp1/1p3Pkp/2p5/7K/2p2P2/5n2/8 w - - 1 54[/pos]
We have been wrong since 2014?
