Scotch: 4.Nxd4 Qf6
Definition
“Scotch: 4.Nxd4 Qf6” is a branch of the Scotch Game that arises after the moves 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Qf6. The position is often called the Steinitz or Classical Variation of the Scotch Game. Black immediately develops the queen to f6, attacking the knight on d4 and the pawn on f2 while discouraging White from playing the natural 5.Nb5 or 5.Nxc6. In ECO (Encyclopaedia of Chess Openings) it is catalogued under code C45.
Move Order and Basic Position
After 4…Qf6 the key features of the position are:
- Material is equal; both sides have developed one minor piece.
- The black queen is active but also potentially exposed to tempo-gaining attacks.
- White’s options include 5.Be3, 5.Nb5, 5.Be2, or the sharply theoretical 5.Nb5.
Strategic Ideas
White’s overall plan is to exploit the premature queen sortie by developing rapidly and seizing central space. Typical themes include:
- Rapid Development: 5.Be3 and 6.Nc3 hit the queen and mobilize pieces.
- Space Advantage: The central pawn duo (e4 & d4) can give White a long-term edge.
- Queenside Expansion: In some lines White castles queenside and launches pawns on the kingside.
Black, on the other hand, aims to justify the queen’s activity by pressuring f2 and d4, exchanging pieces to ease cramped space, and sometimes castling queenside.
Theory and Critical Lines
-
5.Be3 – The main line. Black replies 5…Bc5 6.c3 Nge7 7.Bc4 when both sides enter rich middlegames.
-
5.Nb5 – The Steinitz Invitation. After 5…Bc5 6.f4 Bb6 7.e5 the game becomes highly tactical. White tries to refute the early queen move by direct attack.
-
5.Nxc6 – Less common; Black recaptures 5…dxc6 and retains the bishop pair and a solid but slightly passive structure.
Historical Context
Wilhelm Steinitz employed 4…Qf6 during the mid-19th century, advocating it as a dynamic reply to the fashionable Scotch. Although later champions (Lasker, Capablanca) preferred 4…Bb4 or 4…Qh4+, the line has never disappeared and received theoretical updates from grandmasters like Alexei Shirov and Peter Svidler in the modern era.

Shirov’s energetic play showcased the pressure White can build while Black strives for counterplay on the f-file and long diagonal.
Typical Tactical Motifs
- Fork on c7: After Nb5 White eyes both c7 and d6.
- Discovered Attack on the Queen: Nc3 or Be3 often kicks the queen.
- Bishop Sacrifice on f7: In some sharp lines Bxf7+ exploits the queen’s presence on f6.
Practical Tips
- As White, keep developing with tempo; every threat to the black queen matters.
- Be cautious of premature pawn grabs; Black’s queen can switch flanks quickly.
- As Black, avoid falling behind in development—timely …Nge7 and …d5 break frees the position.
Interesting Facts & Anecdotes
- The move 4…Qf6 caused a stir in the 1800s; Steinitz argued that “the queen is not a piece to be hidden.”
- In correspondence chess, modern engines show the line as fully playable for Black, reviving its reputation.
- Magnus Carlsen has tried 4…Qf6 in online blitz, showing even World Champions keep the line in their arsenal.
