NEW UPDATED OPENING LINE

[November 02, 2017] Updated Opening Line by Bojan Vučković:
King’s Indian Defense, King’s Knight Variation

[Line 125 : 1. d4 Nf6 2. c4 g6 3. Nf3]

The King’s Knight Variation 3. Nf3 is often an introduction to the fianchetto lines of the Indian Defenses. After 3… Bg7, move 4. Nc3 transposes to Line 150, and against 4. g3 the most popular lines are examined elsewhere: the King’s Indian Defense 4… O-O in our Lines 126-130, the solid 4… c6 in Lines 131-132, and the  Gruenfeld Defense 4… d5 in Lines 133-135.

After 4… c5 White usually continues with 5. Bg2. Besides 5… cxd4, Black has an interesting sideline in 5… Qa5+, trying to disrupt White’s common setup. The logical follow-ups after the three most logical replies are: 6. Nc3 Ne4 7. Qd3 cxd4 8. Nxd4 Nc5, 6. Bd2 Qb6 7. dxc5 Qxc5 8. Qb3 Nc6 and 6. Qd2 Qxd2+ 7. Nbxd2 cxd4 8. Nxd4 Nc6. Regardless of the chosen variation, Black should have sufficient resources to get even positions. If White plays 5. d5, Black also has a promising option: 5… b5 6. cxb5 Qa5+ 7. Bd2 Qxb5.

Another possible setup for Black is the double fianchetto: 4… b6 5. Bg2 Bb7. Though White has a slight space advantage, it’s hard for him to gain a tangible plus.
