E65 King’s Indian Defense: Fianchetto Variation, Yugoslav Variation

E65 holds two named lines, all under the name King’s Indian Defense. It leaves E64 (King’s Indian Defense: Fianchetto Variation, Yugoslav System) with 7.Nc3. Both kings have castled by the end of the reference line, White on move 6 and Black on move 4. That final move, by the knight, opens a line for the rook on a1.
