Focus on the Games That Matter to Your Repertoire
Your opening repertoire contains the positions and variations that are relevant to your own chess. But a PGN collection may contain thousands of games, many of which have nothing to do with the openings you play.
ChessSpider! lets you connect your repertoire to your PGN collections and find the games that contain positions from your repertoire.
You can then investigate those games, examine the variations and keep your opening preparation informed by actual games from the collection.
