Scotch Game: Dubois-Reti, Gambit & Anderssen Attack
Scotch Game
Definition
The Scotch Game is an open chess opening that begins with the moves 1. e4 e5 2. Nf3 Nc6 3. d4. White immediately strikes at the center, forcing the pawn exchange 3…exd4 and leading to lively, tactical play. The opening is named after an 1824 correspondence match between Edinburgh and London in which the Scots championed the line.
Typical Move-Order
Main starting sequence: 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4.
Strategic Ideas
- Rapid development for White with pieces on natural squares (Nc3, Bc4, 0-0).
- Open central files encourage piece activity and early tactical skirmishes.
- Black chooses between solid lines (…Bc5, …Nf6) or sharper alternatives (…Qh4+, …Bb4+).
Historical & Modern Usage
The Scotch was popular in the 19th century thanks to players like Alexander McDonnell and Paul Morphy. It fell out of fashion when Wilhelm Steinitz showed how Black could equalize with careful play, but it roared back after Garry Kasparov beat Anatoly Karpov with it in the 1990 World Championship (Game 20). Today it is a mainstay from club level to elite play because it avoids the vast theory of the Ruy Lopez.

Kasparov’s energetic central play showcased the opening’s attacking potential.
Interesting Facts
- In the 19th century, playing 3.d4 was considered almost reckless; today it is seen as objectively sound.
- Because it removes Black’s e-pawn early, the Scotch often sidesteps many long, drawish Ruy Lopez endgame lines.
Dubois-Reti Variation (Scotch Defence)
Definition
The Dubois-Reti Variation is a counter-attacking line for Black in the Scotch Game that arises after 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4 g6. Black fianchettoes the king’s bishop instead of occupying the center with pieces.
Naming
Named after the 19th-century Italian master Serafino Dubois and the Czechoslovak-Austrian grandmaster Richard Réti, both of whom employed the setup.
Strategic Features
- …g6 and …Bg7 put long-term pressure on d4 while preparing …Nf6 and short castling.
- Black concedes central space early but aims for piece activity on the long diagonal.
- White can choose between solid development (5.Nxc6, 5.Be3) or sharp lines (5.Nc3, 5.Bf4).
Representative Line
1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4 g6 5. Nc3 Bg7 6. Be3 Nge7 leads to a flexible Pirc-like middlegame.
Practical Usage
The variation is relatively rare at elite level but remains a surprise weapon. Players who already favor the Pirc/Modern structures often add the Dubois-Reti to their repertoire so they can reach familiar setups while avoiding heavy Scotch theory.
Notable Example
[[Pgn|e4|e5|Nf3|Nc6|d4|exd4|Nxd4|g6|Nc3|Bg7|Be3|Nge7|Qd2|d6| fen|| arrows|g7b2|squares|d4,e4]]Dubois himself used this scheme in Paris 1862 against Ignatz Kolisch, demonstrating its resilience in the classical era.
Trivia
- The early …g6 is unusual in open games, giving the line an “asymmetrical” flavor more common to the Sicilian Dragon or King’s Indian.
- Réti’s adoption of the variation predates his better-known contributions to hypermodern openings with 1.Nf3.
Scotch Gambit
Definition
The Scotch Gambit arises after 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4. Instead of recapturing the pawn with 4.Nxd4, White gambits the pawn, aiming for rapid development and an attack on f7.
How It Differs from the Italian Evans Gambit
Both openings feature an early Bc4 and a sacrificed pawn, but in the Scotch Gambit the pawn comes from the center (d-pawn) rather than the b-pawn. The resulting positions often transpose to lines of the Two Knights Defense.
Main Variations
- 4…Nf6 5. e5 d5 – The most respected line; Black returns the pawn to blunt White’s initiative.
- 4…Bc5 – Can lead to the Dubois Variation of the Italian if White plays 5.O-O.
- 4…Qe7 – A solid choice, covering f7 and protecting the pawn.
Strategic Themes
- Rapid piece play: White often castles long or short and pushes e5 or f4 to rip open lines.
- Pressure on f7: Knight leaps (Ng5) and bishop batteries threaten direct mates.
- If Black neutralizes the attack, the extra pawn often vanishes, leaving roughly equal endgames.
Famous Game
[[Pgn| e4,e5,Nf3,Nc6,d4,exd4,Bc4,Bc5,c3,Nf6,O-O,dxc3,Nxc3,d6,Bg5,Be6,Nd5,Bxd5,exd5,Ne5| fen|| arrows|c4f7,g5d8|squares|f7]]Adolf Anderssen – Jean Dufresne, Berlin 1852, featured an explosive Scotch Gambit with the kings castled on opposite wings. Anderssen’s victory helped cement the gambit’s romantic reputation.
Did You Know?
- On Chess.com the Scotch Gambit appears in “C44” ECO code, but many lines transpose to C57 (Two Knights).
- Modern engines evaluate the initial gambit as roughly equal, vindicating romantic-era intuition.
Anderssen Attack (within the Scotch Gambit)
Definition
The Anderssen Attack is a razor-sharp sub-variant of the Scotch Gambit characterized by the moves 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Bc4 Bc5 5. c3. White immediately challenges the bishop and opens lines, echoing the Evans Gambit while still a pawn down.
Origin of the Name
Named after Adolf Anderssen, arguably the greatest attacking player of the Romantic era, who used this line to score dazzling victories.
Key Ideas for White
- Play c3–d4 quickly to seize the center and free the queen for Qb3/Qf3 assaults on f7.
- If Black grabs the c3 pawn with …dxc3, White can gain time with Bxf7+, Qd5, or Ng5.
- Development over material: sacrificing additional pawns is common to expose Black’s king.
Typical Continuation
[[Pgn|e4|e5|Nf3|Nc6|d4|exd4|Bc4|Bc5|c3|Nf6|O-O|dxc3|Nxc3|d6|Bg5| fen|| arrows|c4f7,g5e7|squares|f7,e4]]The position teems with tactical threats: Bxf7+, Nd5, and e5 are all in the air.
Famous Example
Anderssen – Kieseritzky, London 1851 (“The Immortal Game”) began as a King’s Gambit but displayed many of the same attacking motifs found in the Anderssen Attack—piece sacrifices to checkmate the king in the center.
Modern Relevance
Though rare in top-level chess because precise defense can neutralize it, the line is dangerous in practical play. Many online blitz specialists use it to generate quick tactical chances.
Fun Fact
- If Black tries to hold the extra pawn with …d6 and …Be6, engines already show +1 for White due to lead in development and unsafe king.
Main Line (Chess Term)
Definition
In chess opening theory, the “Main Line” refers to the sequence of moves judged by consensus (grandmaster practice, engine evaluation, and historical usage) to be the most critical, popular, or theoretically important continuation for both sides. It often forms the backbone against which alternative “sidelines” or “variations” are measured.
Usage in Chess Literature
- Opening manuals highlight the main line in boldface, indenting sub-variations underneath.
- Annotators say “After the main line 10…Be7, Black equalizes” or “Instead of the main line, White can play the offbeat 8.h3.”
- In repertoire books, choosing whether to adopt the main line or avoid it entirely is a key strategic decision.
Strategic & Practical Significance
- Theoretical Benchmark: Other lines are compared to see if they improve or worsen the evaluation relative to the main line.
- Memory Burden: Main lines often require more memorization because they are heavily analyzed.
- Psychology: Playing a main line can signal confidence; avoiding it may be used to evade an opponent’s preparation.
Examples
- Ruy Lopez, Closed: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.O-O Be7 is universally accepted as the main line.
- Sicilian Najdorf main line: 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6.
- In the Scotch Gambit, 4…Nf6 5.e5 d5 is considered Black’s most reliable main line.
Anecdote
When Bobby Fischer was preparing for his 1972 match with Boris Spassky, he surprised experts by eschewing decades-old main lines of the Sicilian Dragon in favor of the previously unfashionable Najdorf, rewriting the theoretical “main line” in the process.
