More of a King's Indian Defense player hangout than a "Study."
A year ago, I started this group and I have been adding material since (as have other users). Currently, we have 31 chapters, including games, tactics, lines to memorize, K.I.D. as White, etc.
If you want to contribute (in any way), message me and I'll add you.
If you find it useful, hit "like" to keep me motivated to make more.
