King's Indian Defense: Sämisch Variation – Double Fianchetto

King's Indian Defense: Sämisch Variation, Double Fianchetto

Definition

The Double Fianchetto line of the Sämisch Variation in the King’s Indian Defense (ECO E81-E83) blends two strategic concepts:
• the classical Sämisch pawn wedge d4–c4–e4–f3, which claims space and clamps the dark squares;
• the hyper-modern idea of fianchettoing both bishops to g2 and b2, exerting long-range pressure on the centre and queenside.
The resulting positions are less sharp than the “main-line” Sämisch with Bg5, yet they remain strategically rich and highly topical in grand-master practice.

Typical Move Order

One of several common sequences is:

  1. 1. d4 Nf6
  2. 2. c4 g6
  3. 3. Nc3 Bg7
  4. 4. e4 d6
  5. 5. f3 O-O
  6. 6. Be3 c6 (…c5 is also popular)
  7. 7. Qd2 a6
  8. 8. g3 b5
  9. 9. Bg2 Bb7
  10. 10. b3 and Bg2–b2 completes the double fianchetto.

Strategic Aims & Ideas

  • For White
    • Control e5 and d5 with pawns & pieces; prepare e4-e5 at the right moment.
    • Use the bishops on g2 and b2 to restrain the queenside and central breaks …c5 and …e5.
    • Launch a minority attack with cxb5/a4, or seize the initiative in the centre with d5/e5 breaks.
  • For Black
    • Typical KID plan …e5 followed by …exd4, trying to keep the position closed for a later kingside pawn storm.
    • Queenside space grab with …b4 to harass the c3-knight and open the a- and c-files.
    • Target the e4-pawn (now less protected because the f1-bishop is on g2) and exploit the a7–g1 diagonal with …Qb6 or …Qb8–a7.

Historical Notes

• The original Sämisch (5.f3) dates back to the 1930s, but the double fianchetto idea appeared only in the late 1970s.
• Early adopters included English grandmasters John Nunn and Jonathan Speelman, who sought a positional answer to the razor-sharp main lines.
• Vladimir Kramnik, Peter Svidler, Ding Liren and Anish Giri have all used the system at elite level, demonstrating that it can both neutralise Black’s attack and play for a win.

Model Game

The following miniature (White eventually won after 15 moves when Black’s queen was trapped) shows several recurring themes: early …b5-bxc4 by Black, the knights jumping to d5/e7, and White’s flexible piece play exploiting the long diagonals.

Highlights:

  • 10…bxc4 is a standard attempt to damage White’s queenside, but it also opens the long a8–h1 diagonal for the bishop on g2.
  • The manoeuvre Nc3–d5–e7+ illustrates a frequent knight hop that exploits the dark-square grip provided by the pawn chain.
  • After 15.Bxd2 Black resigned: his queen is gone, his kingside is drafty, and White’s bishops dominate the board.

Typical Motifs to Remember

  • Minority Attack: c4-cxb5 followed by a2-a4 undermines Black’s queenside expansion.
  • Central Break e4-e5: Often timed to coincide with pressure on d6; if Black captures, d4-d5 can slam the centre shut in White’s favour.
  • Knight Manoeuvres: g1-h3-f2-d3 or e2-c1-d3 aim at e5/c5; Black replies with …Nf6–e8–c7–e6 in many lines.

Interesting Facts & Anecdotes

  • Soviet analysts once dubbed the setup the “Sämisch Hedgehog” because White’s pieces lurk behind a spiky pawn chain waiting to spring.
  • Computer engines initially underestimated the line, giving Black comfortable equality; deeper searches, however, uncovered long-term structural pressure favouring White, renewing its popularity in the 2010s.
  • Because both bishops are already on long diagonals, White can sometimes leave the king in the centre or even castle queenside if required, a flexibility lacking in many other KID systems.
