Chess Opening Preparation, Focused on Your Repertoire
Find the games that matter to the openings you actually play.
ChessSpider! connects your personal White and Black repertoires with your PGN collections, so you can find games containing positions from your repertoire and investigate them.
Fully functional. No registration or credit card required.
Unlimited version after the trial. Purchase is optional and there is no automatic charge.

Start With Your Repertoire
Your repertoire defines the positions and variations that matter to your chess. A large PGN collection, on the other hand, may contain thousands of games that are completely irrelevant to you.
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.
