Representative sequence: 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6 8.d5 Ne7 9.Be3 Ng4 10.Bg5 f6 11.Bh4 Nh6 12.Nd2 Nf7 13.f3 Bh6 14.Bf2 f5 15.c5 f4 16.Nc4 g5 17.Rc1 Ng6 18.cxd6 cxd6. White highlights queenside play while Black musters a kingside assault.
Ideas and Concepts
For White
- Develop harmoniously with
Be3,Qd2,Rc1, andNd2. - Choose between queenside expansion (
c5,b4) or central clamps (f3). - Maintain dark-square control over
d5,e4, andc4. - Castle early to secure the king and avoid premature pawn storms.
For Black
- Prepare the thematic
...f5break with accurate piece coordination. - Use
...c6–...a6–...b5to counter on the queenside. - Pressure
e4with maneuvers like...Re8,...Nh5, and...Nf4. - Stay patient; strike after White commits to a specific plan.
Typical Development Path
A frequent roadmap is 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 O-O 6.Be2 e5 7.O-O Nc6 8.d5 Ne7 9.Be3 Ng4 10.Bg5 f6 11.Bh4 Nh6 12.Nd2 Nf7 13.f3 Bh6 14.Bf2 f5 15.c5 f4 16.Nc4 g5 17.Rc1 Ng6 18.cxd6 cxd6, balancing queenside expansion against Black’s kingside thrusts.
Key Strategic Themes
| Theme | Description |
|---|---|
| Flexible center | White keeps the d5–e4 chain intact, ready for either flank play. |
| Queenside initiative | Rc1, Nb5, and c5 increase pressure on Black’s queenside. |
| King safety | Early castling avoids the risk associated with large pawn storms. |
| Dark-square strategy | White dominates d5/e4; Black seeks counterplay on f4/e5. |
| Counterplay balance | Pawn breaks (c5 or ...f5) must be timed precisely by both sides. |
Major Variations
- Classical line: Standard
Be3,Qd2,Rc1development; small White edge (≈ +0.10). - Early
Qd2: White preparesc5orb4; dynamic equilibrium (≈ 0.00). - Quiet
Rc1setup: Slow buildup with controlled tension, slight pull for White (≈ +0.15). - Against
...Nh5: Balanced structures with mutual chances (≈ 0.00).
Typical Middlegame Plans
White
- Expand on the queenside with
c5,b4, and file pressure. - Coordinate pieces via
Be3,Qd2,Rc1, andNd2. - Redeploy knights to
b3orc5to increase dark-square dominance. - Counter
...f5with timelyf3or central breaks.
Black
- Launch
...f5,...g5, and...f4attacks on the kingside. - Undermine the center with
...c6and...b5. - Occupy dark squares via
...Nh5–f4and bishop shifts. - React to White’s plan before committing to pawn breaks.

Historical & Practical Notes
Svetozar Gligorić popularized this plan in the 1950s, and it was adopted by Karpov, Korchnoi, and Kramnik as a dependable answer to the KID. Modern grandmasters still employ it to avoid theoretical dogfights while preserving strategic tension and long-term chances.
