When annotating games, I sometimes want to add a comment which starts from a position that is different from the current position.
Like:
1. d4 d5 2.c4 { Our previous game went 1.e4 c5 ...}
Or:
25. Bf3 { Here I remembered a similar position from a famous game: <some fen notation>}
When writing/printing this is no problem. But when I want to generate playable pgn for a website, this doesn't work.
Attempting this in pgn would look something like:
>[White "Game 1"]
>[Black "?"]
>[Result "*"]
>1. d4 d5 2. c4 (1. e4 c5) *
>[White "Game 2"]
>[Black "?"]
>[Result "*"]
>1. e4 c5 2. Nf3 ([FEN "rnbqkbnr/ppp2ppp/8/4P3/2Pp4/5N2/PP2PPPP/RNBQKB1R b KQkq - 0 4"] 4... Nc6 5. a3 Nge7 ) *
However, this format is not accepted by my chess program (Chessbase) and also not according to the PGN standard.
Does the PGN standard support something this?
What should I do in order to manage to generate playable pgn for a website?
