E87 King’s Indian Defense: Sämisch Variation, Closed Variation

E87 holds three named lines, all under the name King’s Indian Defense. It leaves E85 (King’s Indian Defense: Sämisch Variation, Orthodox Variation) with 7.d5. White’s pieces and pawns attack ten squares in Black’s half, level for the most of the 39 King’s Indian Defense codes. Its deepest line, King’s Indian Defense: Sämisch Variation, Orthodox Variation, Bronstein Variation, runs to 12...Nxc4, the third-longest of the 39 King’s Indian Defense codes. Material is no longer level at the end of two of its lines; the widest gap, two pawns in White’s favour, comes in King’s Indian Defense: Sämisch Variation, Bronstein Defense.
