I still don't know how you put the annotation with the opening name in the games as annotation with pgn extract.
pgn-extract cannot do it automatically. I have a script that can do it, but is using eco.pgn which is different from chessbase.

Can you please share this script with me, and tell me how to use it.
The tactical analysis from chessbase takes to much time for large pgn databases.

Re: How to cut these pgn games.

For the ones interested. I have find an easy solution to cut games for training purposes.

After running tactical analysis in Chessbase 15. Open the pgn file in Scid an export the database to a new pgn database with these settings:

With these settings:
Add games to an existing file? No
Export comments? Yes
Strip square/arrow mark codes from comments? Yes
Indent comments? No
Export variations? Yes
Indent variations? No
Column style (one more per line)? Yes
Symbolic annotation style: Yes

Convert null moves to comments Yes

Than open the pgn file in a text editor and replace ':' after the ECO code, with' }*'
After opening the database in Chessbase the games will be cut, you just have to convert to Chessbase format, and replace the games in the pgn file.
The advantage that way is that also some annotations and variations will be preserved.

You can also cut the games by opening a pgn database with no annotations in Chess Assistant 19. Than go to Annotate opening in the Advanced menu. It is a much faster way that also gives good results.
Than open this pgn in SCID and export it with these settings:

With these settings:
Add games to an existing file? No
Export comments? Yes
Strip square/arrow mark codes from comments? Yes
Indent comments? No
Export variations? Yes
Indent variations? No
Column style (one more per line)? Yes
Symbolic annotation style: No

Convert null moves to comments Yes

Than open the pgn file in a text editor and replace '{=}' with '*', and also '$' with '*'

Post by Jonathan003 » Fri Dec 13, 2019 8:31 pm

There is a problem if there is a '{Predecessor:}' annotation before the eco code.
It can be solved by first replacing '{Predecessor:}' with '{Predecessor$}'. Than after replacing ':' with' }*', replacing
'Predecessor$}' again with '{Predecessor:}'.

This is an example how cut games looks like after Chessbase Tactical analysis.
