Or extract games of a specific player (again using pgn-extract) and you will see how many games are extracted. You can then simply browse the file in scid vs pc. You may also be able to export from scid vs pc games in a range of ECO codes. You can then combine C60.pgn to C99.pgn to get a single Ruy Lopez file. You could use pgn-extract -e3 pgn-file-name to split the pgn file by ECO codes of games, e.g., you will get files C60.pgn to C99.pgn for Ruy Lopez. f4 ( Grand Prix Attack) with both players rated 2700 . Again, you'd have to parse the results, but it seems relevant.įor example, I asked for all games with position after 1.
