The Four Knights Game, a common chess opening that begins with the moves 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6, holds a rich history and unique strategies for both beginners and seasoned players.
With an emphasis on developing knights before bishops, it was a mainstay of the Open Game family until World War I.
Since the 1990s, however, it has seen a resurgence, from the novice level all the way to the grandmaster level.
This article will delve into the intricacies of the Four Knights Game, specifically focusing on the Spanish Variation.
Move Order of the Four Knights Game
The Four Knights Game opens with a typical move order of 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6, although the knights may develop in any order to reach the same position (e.g., such as out of the Petrov as well).
This opening adheres strictly to the principle: “Develop knights before bishops.”
The Spanish Variation, characterized by 4.Bb5, offers several tactical opportunities and strategic complexities.
Theory, Strategy and Purpose of the Four Knights Game
The Four Knights Game encourages quiet positional play.
However, depending on the variations selected, there can be instances of sharp and complex gameplay.
Strategically, the opening is designed to allow for steady development and control of the center, facilitating early castling and safety of the King.
Variations of the Four Knights Game
Several variations exist within the Four Knights Game, each offering unique positions and tactical considerations.
The Spanish Variation (4.Bb5) is the most common, and it can be further divided into sub-variations based on Black’s fourth move.
These include the Symmetrical Variation (4…Bb4), the Rubinstein Variation (4…Nd4), the classical move (4…Bc5), and a recent attempt with 4…Bd6.
Besides the Spanish Variation, White may also choose to proceed with 4.d4, known as the Scotch Four Knights Game.
Alternately, 4.Bc4 (the Italian Four Knights Game) and 4.g3, a favored move by Grandmaster Igor Glek, are other possible variations.
More rarely seen are 4.Be2, 4.a3 (the Gunsberg Variation), and the dubious gambit 4.Nxe5 (the Halloween Gambit).
Let’s look at these variations in more detail below:
The 4.Bb5 Spanish Variation in the Four Knights Game
In the Four Knights Game, White’s most common move is 4.Bb5, also known as the Spanish Variation.
It is considered the strongest move along with 4.d4 as a continuation in the Four Knights Game.
This variation can be mirrored from the Ruy Lopez, Berlin Defense, underscoring its flexibility and strategic depth.
Upon 4.Bb5, Black is presented with four key alternatives to consider.
4…Bb4: The Double Spanish Variation
The first, and perhaps the most straightforward, is 4…Bb4.
This choice of move leads to what is known as the Symmetrical Variation, also referred to as the Double Spanish Variation.
The symmetry is a result of both players mirroring each other’s moves, creating an evenly balanced board.
4…Nd4: The Rubinstein Variation
For a more aggressive stance, Black can opt for 4…Nd4, initiating the Rubinstein Variation.
In this case, it might appear that White can gain an advantage by capturing a pawn with 5.Nxe5, but this is a deceptive prospect.
Black can quickly regain the pawn while also obtaining the bishop pair advantage through 5…Qe7 6.Nf3 (6.f4 Nxb5 7.Nxb5 d6) Nxb5 7.Nxb5 Qxe4+ 8.Qe2 Qxe2+ 9.Kxe2 Nd5 10.c4 a6.
Most often, White responds with 5.Ba4, inviting Black to continue in a gambit style with 5…Bc5!? 6.Nxe5 0-0 7.Nd3 Bb6 8.e5 Ne8 followed by …d6.
On the other hand, 5.Nxd4 exd4 6.e5 dxc3 7.exf6 Qxf6 (7…cxd2+? 8.Bxd2 Qxf6 9.0-0 is perilous for Black) 8.dxc3 Qe5+ is an alternative line that might deter Black players from choosing the Rubinstein Variation, as it often results in a quick draw after 9.Qe2 Qxe2+.
4…Bc5: A Classical Response
Another response for Black is the classical 4…Bc5, which is not only perfectly playable but has a rich history in chess literature.
The famous game between Louis Paulsen and Paul Morphy from the First American Chess Congress in 1857 is a classic example of this variation in action.
4…Bd6: A Recent Experiment
In recent years, 4…Bd6 has been tried with varying degrees of success.
This move mitigates the impact of 5.Bxc6 as it can be smoothly countered with 5…dxc6, resulting in a balanced game for Black.
Should White choose a quieter response, Black has the option to regroup with …0-0, …Re8, …Bf8, and …d6, building a solid and flexible formation.
In summary, the Spanish Variation with 4.Bb5 in the Four Knights Game offers an intriguing blend of classic chess principles and dynamic opportunities for both White and Black.
It encapsulates the strategic depth of the Four Knights Game, making it a fascinating area of study for all chess enthusiasts, from novices to grandmasters.
The 4.d4 Scotch Four Knights Game
In the Four Knights Game, the move 4.d4 by White initiates the Scotch Four Knights Game.
4.d4 is considered alongside 4.Bb5 as the strongest continuation by white overall.
This move seeks to immediately contest the center and results in a more open position, which could also be reached from the Scotch Game by following the move order 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3.
This line was famously used in the fifth game of the 1996 Deep Blue versus Garry Kasparov match.
The decision to choose the Four Knights (3.Nc3) move order over the Scotch (3.d4) could be influenced by several reasons:
- Avoiding Black’s Immediate Responses: After 3.d4 exd4 4.Nxd4, Black has the option to choose 4…Bc5 or 4…Qh4. Both these moves can be problematic for White, leading to potentially complex positions that White might prefer to avoid.
- Option for the Belgrade Gambit: Another reason for White’s preference for the Four Knights move order could be a potential intention to play the Belgrade Gambit (1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5!?). This is an aggressive gambit where White sacrifices a pawn for quick development and control of the center. This gambit is not reachable from the Scotch move order. However, it’s worth noting that the Belgrade Gambit is a distant second in popularity to the more traditional 5.Nxd4, which seeks to regain the pawn immediately without the inherent risks of the gambit.
Therefore, the 4.d4 Scotch Four Knights Game is an interesting variation that provides a blend of tactical opportunities and strategic complexities.
Whether it’s an ambitious aim to employ the Belgrade Gambit or a strategic choice to avoid certain lines of the Scotch Game, White’s choice of the 4.d4 variation opens up a myriad of engaging possibilities in the Four Knights Game.
The 4. Bc4 Italian Four Knights Game
The move 4.Bc4 initiates the Italian Four Knights Game, also known as the Prussian Four Knights Game.
This line was quite popular in the 1880s.
However, according to Pinski, it is considered inferior, and International Master (IM) Larry D. Evans refers to it as an outright mistake.
Black can maintain the symmetry with 4…Bc5, leading to the quiet Giuoco Pianissimo.
It is more common for White to reach this position through the Giuoco Piano move order: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nc3 Nf6.
This line is preferred by many younger players due to its straightforward development.
Notably, it was also used by Nigel Short in his victory against Antoaneta Stefanova.
One of the critical issues with this line in the Four Knights Game is that after 4.Bc4, Black can execute the “center fork trick” with 4…Nxe4!
In response, the move 5.Bxf7+?, while superficially attractive, ultimately hands over the bishop pair and central control to Black.
After 5…Kxf7 6.Nxe4 d5 7.Neg5+ Kg8, Black is already threatening 8…e4.
Following 8.d3 h6 9.Nh3 Bg4, Black achieves a powerful position with an unopposed light-squared bishop, robust central pawns, and a well-secured king. Meanwhile, White has to figure out how to bring the displaced knight on h3 into the game.
A better response from White after 4…Nxe4 is 5.Nxe4.
Even though 5…d5 gives Black a good game by regaining the piece, this line gives White a chance for equality.
A different try is 5.0-0!?, which transposes the game into a variation of the Boden–Kieseritzky Gambit.
This line offers a unique blend of strategic and tactical complexities, suitable for players who enjoy dynamic and tactical positions.
However, it requires careful handling and precise play due to the sharp nature of the resulting positions.
The 4.g3 Variation
Grandmaster Igor Glek has often used 4.g3, preparing to develop the bishop to g2.
According to Pinski, Black’s primary responses are 4…Bc5 and 4…d5, both of which are considered to equalize for Black.
There have been some trials of a Halloween Gambit-style move with 4…Nxe4 at the grandmaster level, as seen in games between Ilya Smirin and Bartłomiej Macieja.
The 4.Be2 Variation
While not a common move, 4.Be2 is playable.
For instance, if Black plays 4…Bb4, White can respond with 5.Nd5, 5.0-0, or 5.d3, all of which maintain equality with accurate play.
The 4.a3 Variation
The quiet move 4.a3, known as the Gunsberg Variation, is a specialty of Polish grandmaster Paweł Blehm.
This move doesn’t commit to any particular structure, preserving flexibility in White’s position.
The 4.Nxe5 Variation
The move 4.Nxe5?! is a dubious gambit, often referred to as the Halloween Gambit.
After 4…Nxe5 5.d4, White tries to gain control of the center with his pawns and push the black knights back to their initial squares.
However, Grandmaster Larry Kaufman claims that this line is refuted by 5…Nc6 6.d5 Bb4! 7.dxc6 Nxe4 8.Qd4 Qe7, a sequence credited to Jan Pinski.
Furthermore, according to Max Euwe’s opening series volume 11, Black has a decisive advantage following 5…Ng6 6.e5 Ng8 7.Bc4 d5 8.Bxd5 c6.
Evaluation of the Four Knights Game
The Four Knights Game is generally evaluated at around +0.10 to +0.25 for white.

4. How does the Scotch Four Knights Game differ from the Spanish Variation?
In the Scotch Four Knights Game, which starts with 4.d4, the game typically opens up more compared to the Spanish Variation.
This can lead to dynamic positions and more tactical play.
This variation can also arise from the Scotch Game (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Nf6 5.Nc3).

The Belgrade Gambit is a sharp and less popular variation of the Four Knights Game that begins with the moves 1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6 4.d4 exd4 5.Nd5!?.
White sacrifices a pawn for quick development and attacking chances.
This gambit can only be reached through the Four Knights Game move order and not the Scotch Game move order.
6. What is the Italian Four Knights Game?
The Italian Four Knights Game, also known as the Prussian Four Knights Game, begins with 4.Bc4.
This variation was popular in the 1880s but is now considered inferior due to Black’s ability to seize the initiative with 4…Nxe4!, also known as the center fork trick.

- C49: Refers to the Symmetrical Variation, where 4.Bb5 is followed by 4…Bb4.
9. How do I avoid common pitfalls in the Four Knights Game?
Avoiding pitfalls in the Four Knights Game mostly revolves around understanding the intricacies of your chosen variation.
For instance, in the Italian Four Knights Game, White should avoid the tempting 5.Bxf7+ after 4…Nxe4, as this relinquishes the bishop pair and central control to Black.
Similarly, in the Halloween Gambit, it’s critical to remember that 5…Nc6 6.d5 Bb4! refutes the gambit.
10. How often is the Four Knights Game seen in competitive play today?
The Four Knights Game is not as commonly seen in top-level competitive play today as it once was, largely due to the popularity of more aggressive openings like the Ruy Lopez.
However, it still maintains popularity among club players and beginners due to its straightforward and clear development plans.
Moreover, it occasionally appears in grandmaster play, often as a surprise weapon.
