Chess Opening Preparation, Focused on Your Repertoire
Create. Find. Play. Win.
Find the games that matter to the openings you actually play. ChessSpider! for Windows connects your personal White and Black repertoires with your PGN collections so you can search, investigate, and prepare more effectively.
Start With Your Repertoire
Your repertoire defines the positions and variations that matter to your play. ChessSpider! lets you use your repertoire as the starting point: search your PGN collections for games containing your repertoire positions, then examine the games and variations you are interested in.

Chess Opening Repertoire Management and PGN Search
ChessSpider! brings your opening repertoire and PGN collections together in one Windows application. Create your own repertoire positions and variations for both colours, and search your PGN files for games in which those positions occur. You can then open the relevant games and examine their moves, comments and variations as part of your opening research.
Whether you are preparing for a tournament, reviewing your existing opening choices or studying new ideas, ChessSpider! provides a practical way to connect your personal repertoire with the chess games in your own collections. The application is designed for players who want a more focused approach to chess opening preparation and PGN repertoire management.
