Four Knights Game – Chess Opening
Four Knights Game
Definition
The Four Knights Game is a classical chess opening that begins with the moves 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6. After these four moves, both sides have developed their king’s knight and queen’s knight, hence the name. The resulting positions are typically symmetrical and harmonious, emphasizing rapid development and central control. ECO codes C47–C49 cover the major branches.
Main Line Moves (“Classical Four Knights”)
The most frequently encountered continuation is:
1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5
Black can reply with 4…Bb4 (the Rubinstein Variation), 4…Nd4 (a sharper line), or
4…Bc5. Other respectable fourth moves for White include 4. d4 (the Scotch Four Knights)
and 4. g3 (the Glek System).
Strategic Themes
- Harmony over Imbalance: Both sides enjoy highly coordinated pieces early on. Many resulting structures resemble those in the Ruy López or Scotch Game, but with fewer immediate pawn tensions.
- Central Breaks: Because pawns remain on e4/e5 and d-pawns are still at home, the first pawn break (d2–d4 or d7–d5) often decides the character of the middlegame.
- Piece Play: Knights often hop to d5, d4, or b5, targeting vulnerable squares like c7 and f7.
- Flexible Plans: White can aim for kingside play with moves such as Bc4, 0-0, d3, Re1, and sometimes h3 & g4 (Glek). Black can equalize comfortably with …Be7, …d6, …0-0, and …Re8.
Typical Plans & Ideas
- Scotch Four Knights (4. d4): White immediately challenges the center, often leading to an open position reminiscent of the Scotch Game.
- Rubinstein Variation (4. Bb5 Bb4): Double-pin structure where both bishops pin knights to queens, creating latent tactical possibilities.
- 4…Nd4! Aggressive alternative for Black, pressuring c2 and forcing simplifications that can equalize rapidly.
- Glek System (4. g3): White fianchettoes the king’s bishop, steering the game into quieter, maneuvering channels.
Historical Significance
The Four Knights was fashionable in the late 19th and early 20th centuries when developing pieces quickly was considered an opening virtue in itself. It appeared in world-class play from the Steinitz–Lasker era and remains a solid choice today, especially as a surprise weapon:
- Capablanca vs. Marshall, New York 1918: Capablanca employed the Four Knights to neutralize Marshall’s tactical style and won a model, positional game.
- Fischer vs. Benko, USA Championship 1963/64: Fischer used the quiet Four Knights yet still unleashed a famous kingside attack.
- Carlsen vs. Anand, Candidates 2014: Carlsen tested Anand’s memory with the Scotch Four Knights, securing a solid draw en route to winning the event.

Interesting Facts & Anecdotes
- The opening’s symmetry once led British master Howard Staunton to joke that it was played “by four gentlemen of the cloth”—a nod to its quiet, almost polite nature.
- Even the ultra-tactical Mikhail Tal used the line to lull his opponents before springing complications arising from 4…Nd4.
- The Glek System (4. g3) is named after Grandmaster Igor Glek, who used it to great effect in the 1990s, proving that fresh ideas can still arise from century-old openings.
- With perfect play, engines assess most main lines as equal, but practical chances abound because minor inaccuracies often concede either the d-file or important central dark squares.
Why Choose the Four Knights?
• Simplicity: Ideal for players seeking a sound, theory-light system.
• Flexibility: Transition easily into Ruy-type structures, Scotch-type
tactics, or fianchetto setups.
• Psychological Value: Opponents may be lured into complacency by its quiet
reputation, overlooking latent tactical shots.
