Your Chess Opening Repertoire
— Easier, faster, better

Chess Spyder is a revolutionary new and better way for you to create, import, build, maintain, edit, navigate, train with, and learn your chess opening repertoire.

Why it’s great

  • Get to any variation in just a few clicks.

  • See overview of your entire White or Black repertoire at a single glance. Gaps in your prep become obvious.

  • Instantly see the entire “main line” of the current variation.

  • Immediately see all alternatives at each step of the current main line.

  • Chess Spyder automatically figures out all transpositions — saving you tedious extra work.

  • Chess Spyder is a web service—it works in any browser on desktop, laptop, mobile—on Mac, Windows, iOS, Android, Linux.

Why it’s better

  • Stop scrolling and stepping through long, complicated PGN to find a variation. Just click!

  • Don’t hunt through numerous files to find a line; all your variations are in one place.

  • You don’t have to break up your repertoire’s variations into multiple files or studies (and find names for them!).

  • You’re a human, not a machine. You deserve better than raw PGN.

  • No software to install. No software to update.

Chess Spyder is coming soon!
