Four Knights Game: Spanish Variation, Rubinstein Variation
Four Knights Game: Spanish Variation
Definition
The Spanish Variation of the Four Knights Game arises after the moves 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5. Because each side has already developed both knights (“Four Knights”) and White now places the bishop on b5 as in the Ruy Lopez, the position is half Four Knights, half Spanish (Ruy Lopez)—hence the hybrid name. ECO classifies it as C48.
Main Ideas & Typical Plans
- Central Control: Both sides contest the classical "e" and "d"-files with pieces instead of early pawn breaks.
- Piece Pressure: White’s Bb5 immediately attacks the knight on c6, indirectly pressuring e5. Black can respond with …Bb4, …a6 or …d6 depending on taste.
- Flexible Structures: Pawn structures tend to stay symmetrical for many moves; the first pawn break (d4, d5, or …d5) often determines the strategic character.
- Reduced Theory Load: Compared with the main line Ruy Lopez, the Spanish Four Knights requires less memorisation, making it attractive to club and correspondence players alike.
Typical Continuations
- 4…Bb4 (most common) 5. O-O O-O
- 6.d3 d6 7.Bg5 Rubinstein Variation (see the next definition).
- 6.Bxc6 dxc6 7.d3 Re8—Capablanca’s favourite, keeping a solid centre.
- 4…Nd4!?—The dynamic counter, immediately challenging White’s harmonious setup.
- 4…a6 5.Bxc6 dxc6—Black accepts doubled pawns in exchange for the bishop pair.
Historical Notes
Although the opening dates back to the 19th century, it was given new life by José Raúl Capablanca, who employed it regularly in exhibition matches to steer games toward manoeuvring middlegames he excelled in. Modern elite players call on it as a surprise weapon—Magnus Carlsen used it to defeat Veselin Topalov, Wijk aan Zee 2012.

Interesting Facts
- The move order is a common trick in scholastic play; many beginners expect a Ruy Lopez after 1.e4 e5 2.Nf3 Nc6 3.Bb5 and suddenly find an extra knight on c3.
- Because so few pawns are exchanged early, endgames can arise with the full complement of pawns on both sides—an ideal setting to study pure piece play.
Rubinstein Variation
Definition
A “Rubinstein Variation” is any opening line named in honour of the Polish-Jewish grandmaster Akiba Rubinstein (1882–1961), famed for his systematic development and end-game mastery. Several major openings carry a Rubinstein sub-line, each reflecting Rubinstein’s preference for solid pawn structures and controlled piece play.
Where You’ll Meet the Name
- French Defence, Rubinstein Variation: 1. e4 e6 2. d4 d5 3. Nc3 (or Nd2) dxe4. Black liquidates the centre early, aiming for a sturdy but slightly passive position.
- Nimzo-Indian Defence, Rubinstein Variation: 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3. White opts for a rock-solid pawn chain, delaying the Queenside development in favour of quick castling.
- Queen’s Gambit Declined, Rubinstein: 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 dxc4. Black grabs the c-pawn but yields time for White’s initiative.
- Four Knights Game, Spanish Variation, Rubinstein Line: After 4…Bb4 5.O-O O-O 6.d3 d6, both sides mimic Rubinstein’s classical style—no weaknesses, gradual manoeuvring.
Strategic Hallmarks
- Early Central Resolution: In several Rubinstein lines (French, QGD) one side clarifies the pawn tension quickly, simplifying the position and steering toward the end-game.
- Harmonious Piece Development: Rubinstein prized smooth piece coordination—no awkward pieces, few pawn weaknesses.
- End-game Readiness: Because many Rubinstein structures feature open files and symmetrical pawns, trading into favourable endings is a recurring theme.
Iconic Games
- Korchnoi – Karpov, World Ch. 1978 (G16) – French Defence, Rubinstein Variation. Karpov’s resilience with the isolated queen’s pawn ending remains a textbook example of defence.
- Kasparov – Karpov, World Ch. 1985 (G11) – Nimzo-Indian, Rubinstein. A model attacking game by Kasparov that began from a seemingly quiet Rubinstein setup.
- Rubinstein – Tarrasch, Vienna 1908 – The master himself demonstrates the QGD Rubinstein, showing flawless technique in exploiting an extra pawn.
Why So Many Rubinsteins?
Unlike variations named for a single spectacular novelty, Rubinstein’s lines embody his overall chess philosophy: eliminate weaknesses, improve pieces, and win the end-game. As a result, different opening families adopted his treatment of typical structures, hence multiple “Rubinstein Variations.”
A Fun Anecdote
At the 1909 St. Petersburg tournament Rubinstein was asked why he so often exchanged in the centre. He reportedly replied, “I like the serenity of equal pawns—and the anxiety of my opponent when he realises every end-game is lost for him.” Whether apocryphal or not, the quote captures the quiet confidence that made Rubinstein’s name synonymous with solid yet poisonous chess.
