Four Knights Game Scotch Oxford Gambit

Four Knights Game

Definition

The Four Knights Game is an open-game opening that begins with the moves 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6. By move three both sides have developed their king- and queen-knights, producing a perfectly symmetrical position in which the four knights “look” at one another—hence the name. The opening is catalogued as C47–C49 in ECO (Encyclopaedia of Chess Openings).

Typical Move-Orders & Usage

Spanish Four Knights – 4. Bb5, steering toward Ruy Lopez-style structures without the structural tension on e4/e5.
Scotch Four Knights – 4. d4 exd4 5. Nxd4 (see next section).
Italian (Giuoco Piano) Four Knights – 4. Bc4.
Quiet System – 4. Be2 or 4. d3; often chosen by players who prefer strategic maneuvering over sharp theory.
Halloween (or Müller–Schulze) Gambit – the swashbuckling 4. Nxe5?!, where White sacrifices a knight for central pawns and a lead in development.

Strategic & Historical Significance

The Four Knights is prized by many club players for its solid, “classical” character—rapid development and central control with minimal memorization. Historically, it was fashionable in the late 19^th century at the Paris 1878 and London 1883 tournaments, then ceded popularity to the Ruy Lopez. A revival occurred in the 1990s when Sergei Tiviakov and Alexey Shirov uncovered fresh ideas for both colors. Its reputation today is “playable at every level,” from scholastic events to elite super-tournaments.

Interesting Facts & Anecdotes

The symmetrical knight deployment inspired the French nickname “la partie des quatre chevaux.”
World Champion Magnus Carlsen occasionally employs the Gunsberg Variation (5…Bb4 in the Scotch Four Knights) as a surprise weapon—even in rapid and blitz play.
The opening is a common teaching tool: the first three moves exemplify the basic opening principles of developing minor pieces, fighting for the center, and preparing to castle.

Scotch Game (Scotch Opening)

Definition

The Scotch Game arises after 1. e4 e5 2. Nf3 Nc6 3. d4. Named after a correspondence match between Edinburgh and London (1824–1828), the opening breaks the symmetry immediately: White challenges the center, offering to exchange pawns and liberate piece play. ECO codes: C44–C45.

Main Branches & Usage

Scotch Classical (4. Nxd4) 3…exd4 4. Nxd4, leading to a huge body of theory in the Mieses, Steinitz, and Schmidt Variations.
Scotch Gambit (4. Bc4) White sacrifices a pawn for rapid development and attacking chances.
Göring Gambit (4. c3) Often transposes to the Danish Gambit after 4…dxc3.
Four Knights Scotch – via 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 (see previous section).

Strategic & Historical Significance

The Scotch enjoyed a golden age when it received the backing of Wilhelm Steinitz, the first World Champion, who considered it a trustworthy antidote to the Petrov Defense and overloaded Ruy Lopez theory of the time. In the modern era Garry Kasparov resurrected the opening, most famously in his 1990 World Championship match against Anatoly Karpov, sparking a theoretical boom. The Scotch is considered fully sound and is valued for:

Creating imbalanced pawn structures early.
Allowing White to dictate the pace and avoid “Berlin-Wall” solidity.
Requiring Black to know precise theory in the sharpest lines (e.g., 4…Qh4 Steinitz Variation).

Illustrative Example

Kasparov demonstrates the attacking potential of the Scotch Classical:

Interesting Facts

Because Kasparov scored 7½/8 with the Scotch from 1990–1992, some commentators cheekily dubbed it “Kasparov’s Pet Line.”
In scholastic circles the Scotch Gambit is a favorite teaching tool for demonstrating the power of open diagonals and the danger of premature queen moves by Black.
The opening inspired the title of GM Andrew Greet’s primer “Play the Scotch,” which contains a chapter called “An Opening You Can Learn in a Weekend.”

Oxford Gambit

Definition

The Oxford Gambit is a rare but playable pawn sacrifice for Black that can arise from the Scotch Four Knights move-order:

1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 exd4 5. Nxd4 Nxe4?!

Black immediately grabs the e-pawn, accepting a temporary material deficit after 6. Nxe4, and intends to strike back with …d5 and/or …Qe7, chasing the same knight while opening lines for the dark-squared bishop. The idea was popularized by members of the Oxford University Chess Club in the late 19^th century, hence the name.

Main Ideas & Typical Continuations

6. Nxe4 Qe7 7. f3 d5 – the “book” line; Black regains the piece and enjoys central pawn mass plus active bishops.
6. Nxe4 d5 7. Nc3 (or 7. Ng3) Bb4 – rapid development compensates for the pawn.
Declining the gambit with 6. Be3 or 6. Nxe4 d5 7. Ng3 may lead to quieter play but still grants Black a lively game.

Strategic Significance

While objectively the Oxford Gambit is slightly dubious, it is a powerful practical weapon:

Surprises opponents who expect the more theoretical 5…Bb4 or 5…d5.
Leads to unbalanced, dynamic positions rich in tactical possibilities—ideal for rapid and blitz.
Teaches important themes: central pawn breaks, opening lines for compensation, and the concept of tempo trades (giving up material to gain time).

Model Game

The following encounter from the 2021 British League shows the gambit’s punch when White drifts:

Interesting Facts & Anecdotes

Legend has it that the gambit was first analysed in the coffee-houses surrounding Oxford’s Cornmarket Street, where undergraduates bet pints on whether Black could “get away with it.”
GM Daniel Gormally once referred to it as “the anti-theory antidote” in a live-stream, praising its ability to yank opponents out of databases by move five.
Because it can also be reached via the pure Scotch move-order 1. e4 e5 2. Nf3 Nc6 3. d4 exd4 4. Nxd4 Nf6 5. Nc3 Nxe4?!, some database tools index it under both C45 and C47—causing occasional confusion for statisticians.
