The idea

Why this opening works

Against the King's Indian, White builds a massive pawn center with d4+c4+e4. This gives you a space advantage and clear plans — push on the queenside with c5 or hold the center and restrict Black. Black's kingside counterplay is slow if you know the right moves, making this a reliably good position for White.

What to remember

  • Know the first 8 half-moves of the main line.
  • Understand the purpose of your key moves before adding more theory.
  • Practice the branches until you can respond without move-order guessing.

Move by move

The moves worth understanding

Theory sticks when every move has a job. Start with these ideas from the trainer.

Scroll down through 8 positions

  1. Position 1 of 8

    1.d4

    d2 → d4

    Controls the center. Against the King's Indian, White aims to build the biggest possible pawn center.

  2. Position 2 of 8

    2.c4

    c2 → c4

    Expands in the center and prepares Nc3. Together with d4, this controls all the key central squares.

  3. Position 3 of 8

    3.Nc3

    b1 → c3

    Develops the knight to support e4. The plan is d4+c4+e4 — a massive pawn center.

  4. Position 4 of 8

    4.e4

    e2 → e4

    Completes the ideal pawn center: d4+c4+e4. White now has a huge space advantage and Black is cramped.

  5. Position 5 of 8

    5.Nf3

    g1 → f3

    Develops the knight, supports d4, and prepares to castle. A natural move completing kingside development.

  6. Position 6 of 8

    6.Be2

    f1 → e2

    The Classical approach — develops the bishop modestly but solidly. Prepares O-O and keeps all options open.

  7. Position 7 of 8

    7.O-O

    e1 → g1

    Castles to safety. White's plan is now to push on the queenside (b4, c5) while the center stays solid.

  8. Position 8 of 8

    8.d5

    d4 → d5

    Closes the center — a key strategic decision. Now the battle is on the flanks: White pushes c5+b4 on the queenside, Black pushes ...f5 on the kingside.
