Alekhine's Gun is a heavy-piece formation in which both rooks are doubled on a file with the queen stationed directly behind them. The name comes from a famous game by world champion Alexander Alekhine against Aron Nimzowitsch at San Remo 1930, where the tripled major pieces squeezed Black into total paralysis. It is the most concentrated form of pressure chess allows on a single line — three guns, one target.
What Is Alekhine's Gun?
Alekhine's Gun is a specific, maximal form of the battery: all three of your major pieces occupy one file, rooks in front, queen at the rear. On the board it might look like rooks on c2 and c3 with the queen on c1 — a column of force bearing down the c-file.
What makes the formation terrifying is arithmetic. Any entry square on the file is now attacked three times, so it would need three defenders just to stay balanced. Any piece or pawn on the file is effectively under permanent siege. And because the capturing sequence starts with a rook, the defender cannot solve the problem with a favorable trade: the gun fires its cheapest ammunition first.
The formation is a strategic weapon, not a combination. It takes several tempi to assemble, so you will rarely "play" Alekhine's Gun as a tactic; you build it against a target that cannot run away, and its effect is usually strangulation — the defender's pieces become chained to the file until something elsewhere collapses.
The Original: Alekhine–Nimzowitsch, San Remo 1930
The christening game is worth knowing. Playing White against Nimzowitsch's French Defense, Alekhine obtained a grip on the c-file and methodically stacked his pieces on it: first one rook, then the second, and finally the queen sliding in behind them — the full gun, aimed at Black's fixed defensive structure.
Nimzowitsch — one of the great defensive minds in chess history and the father of prophylaxis — could do nothing. His pieces were reduced to shuffling in front of the file's entry points, every one of them tied to a defensive duty, his position a textbook case of overloading spread across an entire army. With material still equal, Black soon ran out of moves that did not lose something: an army in zugzwang with the board still full. Nimzowitsch resigned after barely thirty moves, and the formation had its name.
The strategic lesson I want you to take from this game is not "triple on a file." It is that pressure does not need to capture anything to win. Alekhine's pieces took almost nothing for many moves; they simply made every Black piece a full-time defender, and a position with no mobile pieces loses by suffocation.
Why the Queen Goes Behind
The ordering — rooks in front, queen in the rear — is the whole point of the formation, and the logic generalizes to every battery you will ever build.
Suppose the pieces stood the other way, queen leading. Then the first capture on the entry square is made by the queen, and the defender happily gives a rook for her: the exchange wins the defense the material battle. With the rooks leading, the sequence runs rook takes, rook retakes, rook takes again, queen retakes last — at every step the attacker is investing his cheapest available unit while the queen's full power backs the operation from safety.
There is a second, subtler benefit: flexibility. The queen at the rear is not committed. She supports the file but can swing away in one move to the wing where the defense has thinned — and because the defender must keep the file triple-guarded, the wings are exactly where his forces are missing. Many gun positions are won not on the gun's file but on the flank it emptied. The windmill may be chess's flashiest battery; Alekhine's Gun is its patient older sibling.
When to Build the Gun — and When Not To
The gun is slow, so the position must promise that the investment will still matter five moves from now. I look for three conditions:
- A fixed target on the file. A backward pawn, a chronically weak square, or a cramped king that cannot leave the file's blast radius. Against a mobile target the gun is a monument, not a weapon.
- A closed or stable rest of the board. Assembling three pieces on one file strips your presence everywhere else. If the opponent has an active plan — a pawn break, a kingside pawn storm — the tempi spent tripling may hand him the game. The gun belongs in positions where you dictate the pace.
- No counter-battery. If the defender can challenge the file with his own rooks, trades will dissolve the formation. The gun works best when you already own the file outright and the question is only how to convert it.
And a warning from the treasurer's office: while your majors parade on one file, check your own back rank. Tripling on the c-file has walked more than one player straight into a back-rank mate at home. The gun should never cost you your king's insurance.
Alekhine's Gun in Practice
In my tournament practice, the full gun is a rare and happy sight — perhaps a handful of games — but the threat of it is a constant negotiating tool in every open-file battle. The usual sequence at master level: you double rooks, the opponent contests the file, and the question of who can afford the third piece decides the negotiation. Very often the mere possibility that your queen joins the file forces the defender into a concession — a weakening pawn move, a passive piece, an exchange he did not want.
For a club player, the realistic takeaways are these. First, learn the ordering principle: cheapest piece leads the charge on any line where captures will happen. It applies to doubled rooks, to queen-bishop diagonals, to everything. Second, when you do get the gun assembled, do not hurry — the formation wins by accumulation, and the strongest move is often to open a second front while the defender is chained to the first. Third, when the gun is aimed at you, break it early: trade a pair of rooks the moment the doubling starts, because once the third piece arrives, the file is no longer negotiable.
The gun also connects to deeper positional themes. Which file deserves your three best pieces is dictated by the pawn structure — in my book Chess Structures I argue that most structures point to one file as the natural home for the heavy pieces, and the player who identifies it first gets to be the one doing the tripling.

Frequently Asked Questions
What is Alekhine's Gun in chess?
It is a formation with both rooks doubled on a file and the queen placed directly behind them — three major pieces stacked on one line. The arrangement attacks every square on the file three times while ensuring the cheapest piece, a rook, leads any capturing sequence.
Where does the name come from?
From Alexander Alekhine's win over Aron Nimzowitsch at San Remo 1930. Alekhine tripled his major pieces on the c-file with the queen at the rear; Nimzowitsch's pieces became completely tied down defending the file's entry points, and he resigned after barely thirty moves with material still equal.
Why do the rooks go in front of the queen?
Because the front piece is the one offered in any exchange on the file. Rooks in front mean the attacker trades rook for rook while the queen backs the operation; queen in front means the defender can give a rook for the queen and win the material battle. Cheapest ammunition fires first.
Is Alekhine's Gun always winning?
No — it is powerful only against a fixed target on a file the opponent cannot contest. If the defender can trade rooks, generate counterplay elsewhere, or simply walk the target away, the tempi spent assembling the gun are wasted. Evaluate the target before building the artillery.
