French: KIA 2.d3 d5 - King’s Indian Attack

French: King’s Indian Attack (KIA), 2.d3 d5

Definition

“French: KIA 2.d3 d5” is shorthand for a specific branch of the French Defence in which White chooses the King’s Indian Attack (KIA) move-order. The defining sequence is: 1.e4 e6 2.d3 d5. • “French” indicates Black’s choice of 1…e6.
• “KIA” (King’s Indian Attack) describes White’s strategic setup, resembling the King’s Indian Defence but with colors reversed.
• “2.d3” is White’s quiet second move, eschewing the main line 2.d4.
• “d5” is Black’s principled reply, staking a claim in the center.

How It Is Used in Chess

The line is primarily a system opening: White aims for familiar structures and piece placements rather than concrete move-by-move theory. Typical follow-up moves are 3.Nd2, 4.Ngf3, 5.g3, 6.Bg2, 7.0-0, and 8.Re1, after which White will try for an e4–e5 break or a kingside pawn storm with h2-h4-h5. Black, on the other hand, has a variety of plans, most commonly:

  • …c5 and possibly …Nc6, leading to a French-like IQP/isolated structures.
  • …Nf6 and …Be7/…Bb4 followed by castling short, keeping the position solid.
  • …g6, transposing to a Pirc/Modern set-up where the center remains fluid.

Strategic Significance

  • Flexibility for White. By delaying d2–d4, White keeps the light-squared bishop on c1 flexible and can choose the optimal moment to challenge the center.
  • Reduced Theory. Compared to the heavily analysed main lines after 2.d4, the 2.d3 KIA sidesteps most French-Defence theory.
  • King-side Initiative. The typical KIA plan of Nf1–h2–g4 and a pawn storm (h4–h5, g4–g5) can generate a swift kingside attack if Black castles short.
  • Risk vs. Reward. White concedes space in the centre early on; if Black reacts accurately, they can secure a comfortable game with harmonious piece play.

Historical Background

The KIA became popular in the 1950s and 60s, used by American grandmasters such as Bobby Fischer and Larry Evans as a universal system against various defences. Fischer’s attraction lay in its portable nature: the same set-up could be played versus the French, Sicilian, and Caro-Kann. The exact move-order with 1.e4 e6 2.d3, however, is a later refinement designed to provoke …d5 before committing the d-pawn. Modern proponents include Hikaru Nakamura and, in rapid time controls, Magnus Carlsen, who value its surprise factor.

Illustrative Example

The miniature below shows a thematic KIA kingside assault. Moves are in PGN:

[[Pgn| 1.e4|e6|2.d3|d5|3.Nd2|Nf6|4.Ngf3|Be7|5.g3|c5|6.Bg2|Nc6|7.0-0|0-0|8.Re1|b5| 9.e5|Nd7|10.Nf1|a5|11.h4|b4|12.N1h2|a4|13.h5|h6|14.Ng4|Re8|15.Bf4|Bf8| 16.Qd2|Ba6|17.Bxh6|gxh6|18.Nf6+|Nxf6|19.exf6|Qxf6|20.Rab1|c4|21.d4| | arrows|e5d6,g4f6,h5h6| ]]

Key motifs to notice:

  1. White’s knight manoeuvre Nf3–Nf1–h2–g4–f6 aimed straight at the black king.
  2. The pawn storm h4–h5–h6 softens up g- and h-files for piece infiltration.
  3. Black’s queenside expansion with …b5-b4-a4 gained space but failed to create a decisive breakthrough before White’s attack landed.

Typical Move Orders

There are two major branching points for Black after 1.e4 e6 2.d3 d5:

  • 2…d5 3.Nd2
    • 3…c5 4.Ngf3 Nc6 5.g3 Nf6 6.Bg2 Be7 –> A pseudo-Tarrasch structure.
    • 3…Nf6 4.Ngf3 c5 5.g3 Nc6 6.Bg2 Be7 –> Classical French themes.
  • 2…d5 3.Qe2 (the “Fischer move”)
    • 3…Nf6 4.Nf3 Be7 5.g3 0-0 6.Bg2 b6 –> Black adopts a Hedgehog set-up.

Interesting Facts & Anecdotes

  • Bobby Fischer famously beat GM Robert Byrne (New York 1963) with a KIA against the French, though via 1.Nf3 rather than 2.d3.
  • Because the line can transpose to Pirc/Modern structures, databases sometimes classify it under A07 or B10, so searching for games requires multiple ECO codes.
  • The KIA move-order is a favorite weapon in chess960, where sticking to familiar pawn structures is more important than memorizing theory.

Practical Tips

  1. Know Your Plans, Not Lines. Memorize standard piece placements (Nbd2, Nf1, g3, Bg2, Re1) and thematic pawn breaks (e4-e5, g3-g4, h4-h5).
  2. Watch Black’s Center. If Black delays …c5, consider d3-d4 to seize space.
  3. Time Your Pawn Storm. Only launch h4–h5 after completing development; premature attacks can backfire if Black counters in the centre.

Conclusion

The French: KIA 2.d3 d5 is a strategically rich sideline that offers White a low-theory, plan-oriented battle while giving Black fair chances to claim the centre and out-maneuver White’s flexible formation. Its historical pedigree, from Fischer to Nakamura, ensures it will remain a popular practical weapon at all levels.
