Alekhine's Gun: Chess Battery
Alekhine's Gun
Definition
Alekhine's Gun is a powerful battery formation in which a player places both rooks on the same open (or half-open) file, with the queen directly behind them on that file. In other words, from the player's back rank toward the opponent, the lineup is Queen–Rook–Rook on a single file (or rank, in rare horizontal versions). The formation is named after World Champion Alexander Alekhine, who famously used it to crush Aron Nimzowitsch at San Remo 1930.
How it is used in chess
The idea is to concentrate maximum firepower along a single line to:
- Dominate an open file and invade the opponent’s position (often on the 7th or 8th rank).
- Exploit a fixed or backward pawn as a target (e.g., a backward pawn on d7).
- Overload the opponent’s defenders and force tactical concessions.
- Prepare decisive breakthroughs or sacrifices on the target square.
Typically, you first double your rooks on an open file, then bring the queen behind them to complete the “gun.” This is a particular form of a Battery focused on major pieces and an open File.
Strategic significance
- Coordination: Two rooks work best on an open file; adding the queen behind them maximizes pressure.
- Safety: With the queen at the rear, the formation is less likely to be harassed by minor piece tempos than a queen-led battery.
- Binding effect: It can paralyze the opponent if they cannot challenge the file or move the target pawn.
- Conversion tool: Often used to transform a positional advantage (space, better structure) into material gain or a mating attack.
Classic origin and historical note
The term comes from Alexander Alekhine’s win over Aron Nimzowitsch, San Remo 1930, where Alekhine stacked both rooks and then his queen on the same file to unbearable effect. The vivid visual of the three heavy pieces “barreling” down the file inspired annotators to dub it “Alekhine’s Gun.” The label was popularized by chess writers in the mid-20th century and remains standard terminology.
Instructive example (visualizing the formation)
In the following illustrative position, White has completed Alekhine’s Gun on the d-file, bearing down on Black’s backward pawn on d7. White pieces: Kg1, Qd3, Rd1, Rd2, Bc4, Be2, Nc3, Nf3; pawns: a2, b2, c2, d4, e4, f2, g2, h2. Black pieces: Kg8, Qc7, Ra8, Re8, Bc8, Be7, Nf6; pawns: a7, b7, c6, d7, e6, f7, g7, h7.
Here, the target on d7 is fixed and difficult to defend. If Black cannot trade a rook on the d-file or push ...d5 to liberate, the pressure often decides the game.
Typical methods to set it up
- Open or fix a file: Create an open/half-open file and restrain the pawn that sits on it (e.g., ...d7 or ...c7).
- Double rooks: Place your rooks on the file (e.g., Rd1 and Rd2) to seize control of key entry squares.
- Complete the gun: Tuck the queen behind them (e.g., Qd3) to maximize force and prepare tactical shots.
- Breakthrough: Use auxiliary moves (sacrifices, deflections, switches to the 7th rank) once the opponent is tied down.
Famous example
Alekhine vs. Nimzowitsch, San Remo 1930: Alekhine lined up both rooks and then his queen on the same file against a backward pawn, increasing pressure until Black’s position collapsed. The formation became a textbook model for converting positional edges through file domination.
Practical tips
- Do not force it: The “gun” works when the file is secure and the target cannot advance or be easily exchanged.
- Watch counterplay: While assembling the battery, avoid allowing the opponent to open a second front or seize the other open file.
- Be flexible: If the opponent challenges the file, be ready to switch to a rank-based battery or pivot to a different target.
- Timing matters: Complete the formation only when tactically safe—don’t lose tempi to minor piece attacks on your queen.
Defensive resources against Alekhine’s Gun
- Timely pawn break: Push the target pawn (e.g., ...d5) or a related lever to dissolve the file’s pressure.
- Trade a rook: Exchanging one pair of rooks can drastically reduce the sting of the battery.
- Blockade and counter-file: Plant a piece on the file (e.g., a knight on d5) and seek counterplay on an adjacent open file.
- Prophylaxis: Prevent the second rook from doubling or the queen from taking the key square behind the rooks.
Common pitfalls
- Queen in front: Placing the queen ahead of the rooks is not the classic formation and can invite tempos from minor pieces.
- Overcommitment: Over-focusing on one file can neglect king safety or allow a counterstrike elsewhere.
- Illusory pressure: Without a fixed target, the “gun” may look impressive but achieve little.
Interesting facts
- While most examples are vertical (along a file), horizontal versions on a rank do exist but are rarer.
- The psychological effect is real: the visual of three heavy pieces stacked can induce errors as the defender scrambles to parry imagined threats.
- Engines still “approve” the concept—when it’s positionally justified. Modern analysis shows it’s strong only when combined with restraint of the target and limited counterplay.

Mini exercise
In the diagram above, consider typical plans for White after completing Alekhine’s Gun: ideas include doubling on the 7th rank after a rook trade, a sacrifice on d7 to deflect a defender, or switching to the kingside if Black is frozen to the d-file. Ask: “What breaks does Black have to relieve pressure, and how can I prevent them?”
