Old Indian Defense
Initial Moves: 1.d4 Nf6 2.c4 d6
Strategic Summary & Main Idea
The Old Indian Defence is the King's Indian without the fianchetto: 2...d6 prepares ...e5 with the f8 bishop on e7, and the defence trades activity for a compact structure that is easy to set up. The position after 2...d6 is +0.62, and the main line, with ...Nbd7, ...e5, ...c6 and ...Be7, rises to +0.86. The entry's most useful figure concerns the exchanges. The queen trade with 4.dxe5, which takes away Black's castling and looks like the most awkward line, measures −0.01. And the Janowski Variation, with ...Bf5, ranges from −0.13 to +1.63 depending on Black's fourth move.
The pawn structure this opening produces
The Old Indian structure is a King's Indian set up with less ambition. With pawns on d6 and e5 and the bishop on e7 instead of g7, Black does not press d4 along the long diagonal; instead Black waits for White to decide the centre. There are three outcomes. If White keeps the tension with Nf3 and Be2, Black completes ...c6, ...Qe7 or ...Qc7 and chooses between taking on d4 and closing the game. If White pushes d5, the centre closes and the position resembles the closed King's Indian, but with Black's bishop on e7, a defensive rather than attacking piece: Black looks for ...Nc5, which needs preparation, and the ...f5 break loses force. If White takes on e5, the d-file opens, the queens come off and Black's king loses castling — but in a symmetrical structure with no targets, where that barely matters. The sensitive square is e4: in the Ukrainian Variation's ...e4 push, Black's pawn gains space and becomes a target at the same time.
Typical Plans for White
- Develop with Nc3, e4, Nf3 and Be2 and keep the central tension until Black defines the structure
- Push d5 when Black has not prepared ...Nc5, and gain queenside space with b4
- Against the Ukrainian Variation, play Ng5 and g4 attacking the advanced e4 pawn
- Against the Janowski with 4...Nbd7, build e4 with f3 and gain space: the line measures +1.63
- Do not expect an edge from the queen trade with 4.dxe5: the position measures −0.01
Typical Plans for Black
- Complete ...Nbd7, ...e5, ...Be7, ...O-O and ...c6 before any break
- Against d5, prepare ...Nc5 with ...a5 so that b4 does not drive the knight away
- In the Ukrainian Variation, support the e4 pawn with ...Bf5 and not with ...h6
- Against 3...Bf5 4.f3, break with 4...e5 instead of retreating the bishop to g6
- Accept the queen trade without fear: the king in the centre costs nothing in a symmetrical structure

Frequently asked questions
What is the difference between the Old Indian and the King's Indian?
The f8 bishop. In the King's Indian it goes to g7 and presses d4 along the long diagonal; in the Old Indian it goes to e7 and defends. The Old Indian is easier to set up and accepts more passive positions: the main line measures +0.86 after full development.
Is the queen trade with 4.dxe5 good for White?
Not by the measurement. After 4.dxe5 dxe5 5.Qxd8+ Kxd8, the position is −0.01. Black's king loses castling, but with no queens and no open files against it that does not matter, and the symmetrical structure gives White no target.
Is the Janowski Variation worth playing?
It depends on the fourth move. Against 4.f3, the 4...e5 break leads to a queen trade and measures −0.13; the retreat 4...Nbd7 5.e4 Bg6 measures +1.63. It is the largest gap in the entry: the same variation is one of Black's best and one of Black's worst lines, depending on the move after the bishop.
Common Mistakes & Where Most Amateurs Go Wrong
- 01 Retreating the bishop in the Janowski with 4...Nbd7 5.e4 Bg6?. The bishop sits behind White's centre, and g4, the engine's choice, threatens to shut it out of play. The same position that measures −0.13 with 4...e5 measures +1.63. The line:
1.d4 Nf6 2.c4 d6 3.Nc3 Bf5 4.f3 Nbd7 5.e4 Bg6+1.63 - 02 Chasing the knight with 5...h6? in the Ukrainian Variation. The e4 pawn loses its support: 6.Ngxe4 Nxe4 7.Nxe4 and White is a pawn up with the centre intact, +2.13. The line:
1.d4 Nf6 2.c4 d6 3.Nc3 e5 4.Nf3 e4 5.Ng5 h6 6.Ngxe4 Nxe4 7.Nxe4+2.13 - 03 Centralising the knight with 6...Nc5? right after 5.d5. Without ...a5 prepared, 7.b4 drives the piece away, and the knight ends up on a6 out of play: +1.20, against +0.58 for 6...Be7. The line:
1.d4 Nf6 2.c4 d6 3.Nc3 Nbd7 4.e4 e5 5.d5 Nc5 6.b4 Na6+1.20
