Queen's Pawn: Modern (ECO A46–A47)
Queen's Pawn: Modern
The label “Queen’s Pawn: Modern” is the Encyclopaedia of Chess Openings (ECO) umbrella for positions that arise after 1.d4 Nf6 2.Nf3 (ECO codes A46–A47). Unlike sharper Queen’s-Pawn main lines—such as the Queen’s Gambit (2.c4) or the Trompowsky (2.Bg5)—the Modern System is deliberately flexible. White withholds c2-c4 and keeps options open, while Black has committed only a knight. From this calm beginning, the game may transpose into numerous other openings or stay in quiet waters, depending on how each side develops.
Definition
Queen’s Pawn: Modern refers to the family of openings that follow the initial moves:
1. d4 Nf6 2. Nf3
• White’s second move develops a piece, helps guard the e5-square, and prepares quick castling.
• The characteristic feature is White’s decision not to play 2.c4 right away. By delaying the traditional queen-side expansion, White keeps the structure fluid and can choose between a fianchetto (g2–g3 & Bg2), a Colle-style centre (e2–e3 & Bd3), the Torre Attack (Bg5), the London System (Bf4), or even a Catalan after an eventual c4 and g3.
Typical Move Order
Several “default” setups are popular:
- King’s Indian Fianchetto: 1.d4 Nf6 2.Nf3 g6 3.g3 Bg7 4.Bg2 O-O 5.O-O d6. White mirrors Black’s fianchetto and keeps the centre flexible.
- Torre Attack: 1.d4 Nf6 2.Nf3 e6 3.Bg5. White pins the knight, aiming for quick kingside pressure without committing the c-pawn.
- London/Colle hybrids: 1.d4 Nf6 2.Nf3 d5 3.Bf4 (London) or 3.e3 (Colle). Solid, system-based approaches that rely on piece play more than theory.
Strategic Themes
- Flexibility: By not declaring intentions with c2-c4, White can adapt to Black’s setup—entering Catalan, Queen’s Indian, or remaining in system-style structures.
- Quick Development & Safety: Nf3 and g3/Bg2 or e3/Bd3 enable early castling, giving White a safe king before committing central pawns.
- Prophylaxis against …e5: The knight on f3 controls e5, discouraging immediate central strikes by Black.
- Transpositional Weapons: Black must know a variety of openings because a single inaccurate move can funnel the game into a system the defender did not intend.
- Slow-burn Pressure: Rather than direct gambits, White often builds a long-term squeeze, especially on the dark squares if choosing a double-fianchetto setup.
Historical and Theoretical Significance
The Modern System gained momentum in the 1970s when players such as Ulf Andersson and Anatoly Karpov demonstrated that quiet development could out-play aggressive defences.
• ECO A46–A47 codified the opening as mainstream, giving it the “Modern” tag to contrast with classical Queen’s-Pawn lines anchored by 2.c4.
• At elite level, the system is favoured as a transpositional tool. World Champions Kasparov, Kramnik, and Carlsen have all used 1.d4 Nf6 2.Nf3 to sidestep specific preparation.
Illustrative Examples
-
Andersson – Portisch, Milan 1975
Ulf Andersson employed the quiet fianchetto plan (g3, Bg2) and patiently out-maneuvered Portisch in a long endgame. The game is a textbook for the strategic squeeze typical of the Modern System. -
Carlsen – Giri, Wijk aan Zee 2017
The World Champion began 1.d4 Nf6 2.Nf3 d5 3.Bf4, entering a London-Modern hybrid. After typical manoeuvres, Carlsen converted a slight structural edge, illustrating the low-theory, high-skill nature of the opening. -

Interesting Facts & Anecdotes
- A47 and the “Anti-Prep” weapon: Vladimir Kramnik famously used 1.d4 Nf6 2.Nf3 in the 2000 World Championship against Kasparov to avoid the latter’s razor-sharp Grünfeld repertoire.
- Share of Grandmaster Games: According to Mega-Database statistics, the Modern System (A46–A47) accounts for roughly 7 % of all 1.d4 encounters at 2600+ level—modest, but steady and growing thanks to “system” openings’ popularity online.
- Name confusion: Do not mistake “Queen’s Pawn: Modern” for the “Modern Defence” (1.e4 g6). In the ECO lexicon, “Modern” often just means “newer treatment” of an existing opening family.
- Amateur Appeal: Because theory is lighter and plans are logical—develop, castle, probe the centre—many coaches recommend the Modern System as a first 1.d4 repertoire for improving players.
