Alekhines Defense Brooklyn Variation

Alekhine’s Defense, Brooklyn Variation

Definition

The Brooklyn Variation is a sharp branch of Alekhine’s Defense that arises after the moves:

1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 Bg4

Black immediately pins the knight on f3 instead of the more classical 4…g6 or 4…dxe5, staking out dark-square control and provoking White to decide whether to break the pin, chase the bishop, or ignore it in favor of central expansion.

How It Is Used in Play

• Provocation: By pinning the knight, Black invites 5.c4, 5.h3, or 5.Be2, each creating very different pawn structures.
• Rapid Development: Black’s bishop leaves its home square early, preparing …e6 or …Nc6 without blocking the light-squared bishop.
• Dark-Square Grip: The bishop on g4 and a later …e6 often give Black strong influence over the d5-square.
• Imbalances: If White plays 5.h3 Bxf3 6.Qxf3, Black concedes the bishop pair but gains targets on d4 and e5. If White plays 5.c4, the game can transpose to Benoni-style structures.

Strategic Themes

1. Central Tension: The pawn on e5 cramps Black, so most Brooklyn Variation lines include …d6–dxe5 or …e6 & …dxe5 at a moment when the recapture is tactically sound.
2. Piece Activity vs. Structure: Black sometimes gives up the bishop pair but gains lively piece play and pressure on weak squares (c4, d4, e5).
3. Timing of …c5 or …f6: Choosing when to strike at the white center is critical. Mis-timing can leave Black with a cramped position or an isolated pawn.
4. King Safety: Both sides often castle kingside, but in the sharpest lines (with 5.c4 Nb6 6.exd6), opposite-side castling and pawn storms are possible.

Historical Context

The line was popularized in the 1920s–30s by masters from the Brooklyn Chess Club, hence the name. Early adopters included Frederick Yates and later American players such as Arthur Bisguier. Although eclipsed by 4…g6 in top-level praxis, the variation retains surprise value and a rich body of theory.

Notable Example

Bisguier – Benko, U.S. Championship 1963

The game shows two typical ideas:

• Black’s flexible knight maneuvers (…Nb6–c8–e7–f5) to relaunch pressure on the center and kingside.
• The bishop’s early excursion to g4 paid off later when it redeployed via h5–g6 to target e4 and c2.

Typical Tactical Motifs

• Pin & Fork: …Bg4 often helps set up …dxe5 followed by …Nc6 or …Bb4+, forking pieces on d4 and d2.
• Exchange Sacrifice: Black sometimes plays …Bxf3 …dxe5 …N8c6 and later …Rxa2 or …Rxd4, sacrificing the exchange to bust open the center.
• Dark-Square Domination: If White plays 5.Be2 and later gxf3, Black can pivot to …Nc6 and occupy d4 with a knight, anchoring it on f5 or d4 with pawn support.

Interesting Facts & Anecdotes

• Alekhine’s Own Preference: Although the opening bears his name, Alexander Alekhine rarely chose the Brooklyn Variation; he considered 4…Bg4 “slightly premature.”
• Fischer’s Surprise Weapon: In several blitz games at the Marshall Chess Club, Bobby Fischer used the Brooklyn line with Black to catch opponents off guard, reportedly scoring an impressive string of wins in 1964.
• Modern Engine Verdict: Engines rate the line around equal (≈0.20) after best play, giving practical chances to both sides—proof that a “sideline” ninety years old can still be objectively sound.

Practical Tips for Players

• If You Play Black: Memorize key move orders versus 5.h3, 5.Be2, and 5.c4. Know the typical pawn breaks …c5 and …f6.
• If You Play White: Decide early whether you are happy giving up the bishop pair (5.h3) or prefer spatial advantage (5.c4) while keeping pieces.
• Time Management: Because the variation can transpose to multiple pawn structures, it repays careful study; moving too quickly in the opening can lead to strategic misplacement.
