Alekhine Defense: Normal Variation
Alekhine Defense: Normal Variation
Definition
The Alekhine Defense is characterized by the provocative first move
1...Nf6 against White’s 1.e4, immediately attacking the e-pawn and
tempting it to advance.
The term “Normal Variation” (ECO code B04) refers to the most
frequently played main-line sequence:
1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3
From this tabiya, Black may choose between several setups
(4…g6, 4…Bg4, 4…dxe5, etc.), but the position after
White’s 4.Nf3 is what opening manuals label the “Normal Variation.”
Typical Move Order
The moves and their purposes:
- 1.e4 Nf6 – Black attacks the e-pawn, inviting it to over-extend.
- 2.e5 Nd5 – The knight is chased to d5, where it eyes c3 & f4.
- 3.d4 – White seizes space in the center and supports e5.
- 3…d6 – Black undermines e5, hoping to provoke exchanges that loosen White’s center.
- 4.Nf3 – White calmly defends e5 again and prepares to castle.
Strategic Ideas
- Hypermodern Provocation: Black concedes spatial control early, trusting that White’s advanced pawns (e5, sometimes c4) can later be targeted and undermined.
- Piece Play vs. Space: White enjoys more space and freer development, while Black aims for pawn breaks (…c5, …dxe5) and piece pressure on the dark squares.
- Endgame Prospects: If the center liquefies, Black’s minor pieces can become superior because White’s pawns may be overextended or isolated.
- King Safety: Both sides often castle kingside, but asymmetrical pawn structures can lead to opposite-wing attacks if White pushes f4–f5 or Black launches …f6.
Historical Context
Named after the fourth World Champion, Alexander Alekhine, who unveiled
the defense against Efim Bogoljubow at Vienna 1921.
Alekhine’s gesture of leaning back in his chair after playing 1…Nf6
reportedly amused onlookers—he invited the opponent to build a large
pawn center and then planned its destruction.
The “Normal Variation” crystallized in the 1930s and has been employed
by world-class players such as Fischer, Korchnoi, and more recently
Nakamura and Caruana as a surprise weapon.
Famous Games
- Fischer vs. Benko, Candidates 1962 – A textbook example of 4…g6 where Fischer’s space advantage eventually told.
- Karpov vs. Korchnoi, World Championship 1978 (Game 17) – Korchnoi equalized in the 4…Bg4 line, illustrating Black’s resilience.
- Caruana vs. Nakamura, London Chess Classic 2015 – Modern handling with 4…dxe5 leading to dynamic chances for both sides.
Common Sub-lines After 4.Nf3
- 4…g6 – The Fianchetto System (ECO B04) aiming for …Bg7 and pressure on the center.
- 4…Bg4 – The Modern Variation, pinning the knight and immediately increasing tension on d4 and e5.
- 4…dxe5 5.Nxe5 Nd7 – The Exchange line, reducing central pawns and seeking rapid development.
- 4…c6 – A solid but less common plan, preparing …dxe5 without allowing a knight fork on c7.

Interesting Facts & Anecdotes
- Alexander Alekhine supposedly chose 1…Nf6 because he wanted an opening that “did not allow early simplifications,” forcing opponents to make strategic decisions from the very first moves.
- Grandmaster Vassily Ivanchuk once played the Alekhine Defense seven times in a single tournament, scoring an undefeated +3 =4 result, proving its viability at elite level.
- Computer engines initially disliked Black’s early knight hopping, but modern neural-network engines (e.g., Leela Zero) often evaluate the resulting imbalanced middlegames as completely playable for Black.
Why Study the Normal Variation?
For Black, it offers a fighting, asymmetrical game with clear plans and keeps opponents out of heavily analyzed 1…e5 or 1…c5 main lines. For White, understanding how to maintain and exploit a space advantage is a valuable strategic lesson that applies to many other openings.
