Alekhine Defense - Modern Variation

Provoke White's pawns forward, then undermine the overextended center

Try Interactive Lesson

Introduction

The Alekhine Defense, named after World Champion Alexander Alekhine, is one of chess's most provocative openings. With 1. ..Nf6, Black immediately attacks the e4 pawn and dares White to advance it. This is a hypermodern strategy — rather than occupying the center with pawns, Black invites White to build a big pawn center, then systematically undermines it. The Modern Variation (4. Nf3 Bg4) is the main line, where Black pins White's knight and prepares to challenge the center with ..d6 and eventually ..dxe5 or ..d5. The resulting positions are strategically rich, with Black seeking to prove that White's center is a target rather than an asset.

1. e4

The King's Pawn opening — White claims the center and opens diagonals for the queen and kingside bishop. The most popular first move in chess. Black's main responses: - 1. ..e5 — Open Game, matching White's center - 1. ..c5 — Sicilian Defense, fighting for d4 asymmetrically - 1. ..e6 — French Defense, preparing ..d5 - 1. ..c6 — Caro-Kann, also preparing ..d5

1. ..Nf6

The Alekhine Defense! Instead of matching White in the center, Black immediately attacks the e4 pawn with the knight. This is a hypermodern provocation — Black wants White to push 2. e5, gaining space but creating a target. Alexander Alekhine introduced this idea in the 1920s, shocking the classical establishment that believed in occupying the center with pawns.

Center ControlTempo
Alternative Moves
e5 — The classical reply, leading to Open Games. Nf6 is more provocative — it challenges White to overextend.
c5 — The Sicilian Defense — also excellent but a completely different character. Nf6 directly attacks e4.

2. e5

White accepts the challenge, pushing the pawn forward to chase Black's knight. This gains space but commits the pawn to an advanced post where it may become a target. White's alternatives: - 2. Nc3 — Vienna-like, defending e4 calmly - 2. d3 — very passive, giving Black an easy game

2. ..Nd5

The knight retreats to d5 — a powerful central square. From d5 the knight eyes c3, b4, and f4. Black's strategy is clear: let White push pawns forward, then attack the overextended center later.

Piece ActivityCenter Control
Alternative Moves
Ne4 — Looks aggressive but the knight is unstable on e4. After d3, it must retreat anyway. Nd5 is much more natural.

White builds the classical pawn center with e5 and d4. This is exactly what Black wanted to provoke — a big center that Black can later target with ..d6 and ..c5. White's alternatives: - 3. c4 — the Four Pawns Attack, even more aggressive - 3. Nc3 — Exchange Variation after 3. ..Nxc3 4. dxc3

3. ..d6

The key counter-attacking move! Black immediately challenges the e5 pawn, the head of White's pawn chain. By striking at e5, Black begins to undermine the center that White spent time building.

Alternative Moves
g6 — Prepares a fianchetto but delays the central challenge. d6 directly attacks the pawn chain.
c6 — Solid but slow — prepares ...d5 later. d6 immediately pressures e5.

4. Nf3

White develops the knight to its natural square, defending e5 and preparing to castle. This is the Modern Variation — White develops pieces before deciding on the pawn structure. The main alternative is 4. c4, chasing the knight and leading to the sharper Four Pawns Attack after 4. ..Nb6 5. f4.

4. ..Bg4

The main line of the Modern Variation! Black pins the f3 knight against the queen, putting immediate pressure on White's position. The bishop also indirectly targets e5 — if the knight moves, e5 falls. This is Black's most active and popular continuation, more dynamic than 4. ..dxe5 or 4. ..g6.

Piece ActivityThreat
Alternative Moves
dxe5 — Releases the central tension too early. After Nxe5, White has a comfortable position. Bg4 maintains pressure.

White develops the bishop to e2, breaking the pin while preparing to castle. A solid, positional choice. Alternatives: - 5. h3 — immediately asking the bishop's intentions - 5. c4 — chasing the knight before developing

5. ..e6

Black supports the d5 knight and prepares to develop the dark-squared bishop to e7. The pawn on e6 also controls d5, reinforcing Black's central grip. This is a solid setup — Black will castle and then look for the right moment to break with ..dxe5 or ..c5.

Nc6 — Also good, developing toward the center. But e6 solidifies the Nd5 first and prepares ...Be7.

6. ..Be7

Black develops the bishop to a modest but functional square. On e7 it doesn't block any pawns and prepares kingside castling. The bishop also supports a future ..d5 push by covering the f6 square if the e5 pawn advances.

Alternative Moves
Nc6 — Develops but blocks the c-pawn. Be7 prepares castling first, keeping ...c5 options open.

White expands on the queenside, kicking the knight from d5. The pawn on c4 also supports d5 control and gives White a broad pawn center. Black must retreat the knight, typically to b6.

7. ..Nb6

The knight retreats to b6, maintaining influence on d5 and c4. From b6 the knight can reroute to c8-e7 or d7 later, or stay put to pressure c4. Black's position is compact and solid.

8. ..O-O

Black castles to safety. With both sides now castled, the middlegame battle will center around whether White's space advantage is an asset or a liability. Black's next plan is to challenge the center with ..dxe5 or ..d5.

King Safety
Alternative Moves
d5 — Premature — after cxd5 exd5, Black's pawn structure is weakened. Castling first is safer.

9. ..Bxf3

Black trades the bishop for the knight. This concedes the bishop pair but damages White's pawn structure after Bxf3 (doubled f-pawns if gxf3) and removes the key defender of e5. Black's position remains solid with a clear plan to attack the center.

Alternative Moves
Bh5 — Retreats but the bishop has limited scope. After g4 Bg6, it gets pushed even further. Trading is cleaner.

10. ..Nc6

Black develops the last minor piece, pressuring d4 and e5. The knight on c6 completes development and prepares for the central battle. Black can now aim for ..dxe5 or ..f6 to challenge White's space advantage.

DevelopmentCenter Control
Alternative Moves
N8d7 — Also reasonable, rerouting toward e5 or f6. But Nc6 directly attacks d4 and is more natural.

Key Takeaways

  • 1...Nf6 provokes White's pawn to e5 — a hypermodern strategy
  • Black lets White build a center, then attacks it with ...d6
  • 4...Bg4 pins the knight defending e5 — the most active plan
  • Trade the bishop for the knight when challenged by h3
  • Black's compact setup is solid — the central battle comes later

Summary

You've learned the Alekhine Defense Modern Variation. Black provokes White's center with 1. ..Nf6, lets White build a big pawn center (e5+d4), then systematically undermines it with ..d6 and ..Bg4. After trading the pinning bishop, Black completes development with a solid, compact position ready to challenge White's overextended pawns.
