When I analyze my chess games for studying, I like to write a high level summary or action items.
For example, a summary of a game might include some positive feedback for myself, as well as constructive action items:
- Good job managing my time. I stayed ahead on the clock the whole game.
- I need to review how to punish ...Nc6.
- I could have mated in fewer moves. Review King/Rook mating pattern again.
These are distinct from per-move analysis comments, because they apply to the entire game.
Is there a standard practice for storing this type of information? It would be great if I could store it in a PGN so that I have all my analysis and game data in one file, but I haven't seen something like this described in any of the PGN specifications.
