Alekhine’s Defense: Definition, ideas & variations
Alekhine’s Defense
Definition
Alekhine’s Defense is a hyper-modern chess opening that begins with the moves 1. e4 Nf6. Black immediately attacks White’s central pawn with the knight, deliberately provoking an advance of White’s center pawns so that they can later be undermined. The opening is named after the fourth World Champion, Alexander Alekhine, who introduced it into top-level practice in the early 1920s.
Typical Move Order & Main Variations
After 1. e4 Nf6, the most common continuation is 2. e5, kicking the knight. From there, the opening branches into several distinct systems:
-
Classical (Main) Variation:
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 Bg4 (or 4…g6)
A traditional set-up in which Black challenges the center with …d6 and often …c6. -
Four Pawns Attack:
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4 Nb6 5. f4
White grabs extensive space with four pawns on e5–d4–c4–f4, aiming for a powerful central bind but risking over-extension. -
Exchange Variation:
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. c4 Nb6 5. exd6
White exchanges on d6, leading to quieter, more positional play. -
Modern (or Accelerated) Variation:
1. e4 Nf6 2. e5 Nd5 3. d4 g6
Black fianchettoes the bishop, maintaining pressure on the dark squares. - Two Pawns Attack (2. e5 Nd5 3. c4): An aggressive attempt by White to gain more space on move 3.
- Sidelines without 2. e5: White can also play 2. Nc3, 2. d3, or 2. e5 followed by 3. Nc3, but these lines are considered less testing.
Strategic Ideas
For Black:
- Tempt White’s pawns forward (e5, d4, c4, f4) so that they become targets.
- Attack the center with pawn breaks …d6, …c5, and …e6.
- Exploit the outpost on d5 for a knight in many lines.
- Rely on piece play and tactical shots against an over-extended pawn chain.
For White:
- Seize space and cramp Black’s pieces.
- Maintain and support the advanced e5 pawn as a spearhead.
- Develop rapidly (Nf3, c4, d4) to avoid falling behind after Black’s pawn breaks.
- Avoid premature pawn moves that might leave weaknesses behind the broad center.
Historical Significance
Although a few earlier masters experimented with 1…Nf6, it was Alexander Alekhine who popularized the defense at the 1921 Budapest tournament, scoring several sparkling victories. He demonstrated that an early knight jump challenging the pawn on e4 could be not only sound but also combative—helping to cement hyper-modern ideas in mainstream opening theory.
Over the decades, leading grandmasters such as Bobby Fischer, Viktor Korchnoi, Lev Alburt, and Vassily Ivanchuk have used Alekhine’s Defense as part of their repertoires, ensuring its continued theoretical relevance.
Famous Games
-
Alekhine – Endre Steiner, Budapest 1921
The debut showcase: Alekhine’s active piece play overwhelmed White’s central pawns and ended in a decisive kingside attack. -
Fischer – Benko, Candidates 1962
Fischer’s precise technique in the Exchange Variation highlighted positional ways to meet the opening. -
Korchnoi – Kasparov, London 1983
Kasparov neutralized the Four Pawns Attack and demonstrated dynamic counterplay, influencing modern assessments of that variation.
Typical Tactical Motifs
- Undermining the e5 pawn: …d6, …c5, and sometimes …f6 can shatter White’s center.
- Knight forks on c2, e3, or d4: Coming from b4, f4, or d5 after pawn exchanges.
- Queenside pawn storms: In the Four Pawns Attack, Black may launch …b5–b4 to open files.
- Dark-square exploitation: The fianchettoed bishop on g7 (Modern Variation) aims at d4 and e5.

Interesting Facts & Anecdotes
- When Alekhine first played the defense, many contemporaries considered it “unsound” because Black apparently violates opening principles by moving the same piece twice and allowing White to build a big center. Alekhine replied, “A large but over-extended center is no longer a center.”
- Grandmaster Lev Alburt authored an entire book series on the opening and championed it in U.S. tournaments during the 1980s, earning the nickname “The Alekhine’s Defender.”
- Despite periodic swings in popularity, the defense scored a respectable 49–51% for Black in modern databases—on par with many classical replies to 1. e4.
- Magnus Carlsen briefly employed Alekhine’s Defense in rapid and blitz play, surprising opponents accustomed to his more classical 1…e5 repertoire.
Summary
Alekhine’s Defense is a provocative, strategically rich reply to 1. e4. By encouraging White to advance pawns early, Black hopes to create long-term targets and dynamic counterplay. The opening has a storied history dating back a century, and its theory continues to evolve, making it a compelling choice for players who relish unbalancing the position from the very first move.
