Old Indian: 3.Nf3 – Definition, themes & transpositions
Old Indian Defence: 3.Nf3
Definition
“Old Indian: 3.Nf3” refers to the variation reached after the moves 1. d4 Nf6 2. c4 d6 3. Nf3. By bringing the king’s knight to f3 instead of the more aggressive 3.Nc3, White adopts a flexible development scheme that keeps several set-ups (King’s Indian, Old Indian, Benoni, Bogo-Indian) in reserve while limiting Black’s immediate options.
Typical Move Order & Key Position
The basic branching point occurs after 3…
- 3…e5 – Black enters the “pure” Old Indian. After 4.Nc3 Nbd7 5.e4 the game resembles a restrained King’s Indian with …e5 already inserted.
- 3…g6 – Transposes to a main-line King’s Indian with the knight already on f3.
- 3…c5 or 3…c6 – Aims for Benoni or Czech Benoni structures.
- 3…Nbd7 followed by …e5 – a pure Old Indian by a different move order, sometimes chosen to avoid early g2-g3 systems.

Strategic Themes
- White’s Flexibility. By delaying Nc3, White keeps the c-pawn’s scope (c4-c5) and the option of a later e2-e4 under better circumstances.
- Black’s Central Tension. If Black opts for …e5, the structure often resembles a closed King’s Indian: White plans d4-d5 or c4-c5, while Black eyes …f5 breaks or queenside expansion with …a5 …Na6 …Nc5.
- Piece Placement. White usually follows up with g3, Bg2 and short castling, then chooses between a queenside pawn storm (b4, c5) or central action (e4, d5).
- Tempo Nuances. Because the knight is already on f3, certain lines where Black plays …Bg4 pinning the knight are slightly less effective; conversely, …e5 lines gain a tempo on Nc3 lines.
Historical Context
The Old Indian Defence itself predates the hypermodern King’s Indian by several decades, appearing in the late 19th century games of Emanuel Lasker and Siegbert Tarrasch. The specific 3.Nf3 move became popular in the mid-20th century when players such as Vassily Smyslov, Bent Larsen, and later Anatoly Karpov adopted it as a low-risk anti-King’s Indian weapon.
Example Game (annotated outline)
Karpov – Nunn, Wijk aan Zee 1981
Karpov’s restrained set-up (g3 omitted) allowed him to seize the centre with e4 and later d5, obtaining a pleasant space advantage and a textbook squeeze on the queenside light squares.
Illustrative Miniature
Gurevich – Short, Manila 1990 (19 moves)
A swift transition to a King’s Indian where White’s quick Re1-e4-d5 plan left Black with a cramped position and ultimately material loss.
Interesting Facts & Practical Tips
- Because the variation can transpose almost anywhere, many repertoire books slot 3.Nf3 under both King’s Indian and Bogo-Indian chapters—handy for repertoire builders who like move-order subtleties.
- Magnus Carlsen has used the line repeatedly as White to sidestep deep King’s Indian preparations; by move 5 his opponents often find themselves in less-studied Old Indian channels.
- The ECO code most frequently associated with 3.Nf3 is E92 when Black plays …e5, but games also spill into E60-E79 (King’s Indian) or A56-A57 (Benoni/Czech Benoni) depending on Black’s third move.
- Engine verdicts rate the line as a solid “plus-equals” for White, but practical chances remain double-edged because pawn breaks (…f5, …c6-d5, or c4-c5) create imbalanced structures.
Common Transpositions & Move-Order Tricks
- 3…g6 4.g3 Bg7 – You are now in a Main-Line King’s Indian, but without the possibility of the sharp Four Pawns Attack (because White’s knight blocks f-pawn advance).
- 3…e5 4.Nc3 – Immediate return to the classical Old Indian structure; White has simply ruled out Black’s option of the Bogo-Indian with …Bb4+.
- 3…c5 4.Nc3 cxd4 5.Nxd4 – Benoni structure, yet White has avoided theoretical lines involving g3 systems.
Summary
The Old Indian with 3.Nf3 is a subtle weapon: solid, strategically rich, and brimming with transpositional possibilities. It allows White to steer the game toward favourite structures while keeping Black guessing—an ideal choice for players who relish flexible, positionally-oriented battles over all-out theoretical duels.
