Dos someone know how it's possible to delete the moves after the name of the opening in this pgn exemple. I want to cut the games that way for training purposes. Also some way to remove these { [%evp 21,27,9,13,6,6,6,14,14] } annotations.

I want to delete all the moves after for exemple '{ A90: Dutch Defence: Miscellaneous and Modern Stonewall (with ...Bd6) }'. I also want to delete all other text comments like the %evp end the %cal. I only want to keep the annotation with the eco code and the name of the opening.

Maybe it can be done with some advanced search and replace options in a text editor like Sublime Text or Ultra Edit?

You need a trailing asterisk in the PGN body text after trimming.
Seems like you are simply looking for a named opening db.

Maybe you want something like this:

pgn-extract and/or Norm Pollock's executables will do it for you.

Posted: **Thu Mar 14, 2019 8:59 pm**

I have booth pgn-extract and/or Norm Pollock's executables but I don't have a lot of experience with it.
I find a way to remove these '{ [%cal Bb1d2,Bd2f3,Bf3e5][%mdl 32]' characters with fenRemove included in Norm Pollock's executables.
I still look for ways to remove these '{ [%evp 15,27,15,26,26,32,11,11,8,10,7,17,17,17,16] }', '[%emt 0:00: 05, and other annotations beside the eco code and opening name. I think I'm going to have to do it manually.
If all annotations where removed except the annotation with the eco code and the opening name, than I could replace } with }*
That would cut the games. But it doesn't work if there are still annotations like { White is slightly better. }, before the annotation with the eco code and opening name.

Alternatively does someone know how to automatically annotate a big pgn file with many games so the games looks like this:

[Event "Example PGN Chess Game Record"]
[Site "Moscow"]
[Date "2003.12.25"]
[Round "2"]
[White "Blaganov"]
[Black "Dufus"]
[Result "1-0"]
[Opening "Scandinavian"]
[ECO "B01"]

1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd8 4.d4 Nf6
{B01 Scandinavian}
5.Bc4 c6 6.Nf3 Bg4 7.Bxf7 Kxf7 8.Ne5 Kg8
9.Nxg4 Nbd7 10.Qe2 Nxg4 11.Qe6# 0-1

Or even better look someting like this. With a more detailed opening name, and with the annotation later in the game.

[White "My White Opening"]

{ A88: Dutch Defence: Leningrad System: 5 Nf3 0-0 6 0-0 d6 7 Nc3 c6 }

You know what I mean. With only one annotation in the game. The annotation with the eco code and the opening name. Without having to type this annotations manually.

pgn-extract can remove comments, problem is not all comments are to be removed.
pgn-extract can cut length at specified plies, problem is his pgn has variable length depends on where the comment with ECO is located.

Thanks Freddy. I will try it.
Can you please give me some guidance, I'm not familiar with this. I'm not a programmer or so.
I have download Phython 3.7.2 from the link you provided and installed it.
I couldn't find python-chess in the link you send. But I found python-chess 0.27.1 here: https://pypi.org/project/python-chess/#files
I downloaded
python_chess-0.27.1-py3-none-any.whl
and installed it from console on windows by typing: pip install python-chess.
What to do next please? Where can I find this 'pgn_modifier.py'

I see you posted some codes. I can select these and copy them but what to do next?

Sorry for my many questions but I want this to work.
