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. ..♘︎f6, 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. ♘︎f3 ♗︎g4) 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

Try this position

1. ..♘︎f6

Attack the e4 pawn with your knight to provoke it forward.

♘︎f6 — 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. ♘︎f6 is more provocative — it challenges White to overextend.

c5 — The Sicilian Defense — also excellent but a completely different character. ♘︎f6 directly attacks e4.

Try this position

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. ♘︎c3 — Vienna-like, defending e4 calmly - 2. d3 — very passive, giving Black an easy game

SpaceCenter Control

Try this position

2. ..♘︎d5

Retreat the knight to a strong central square.

♘︎d5 — 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

♘︎e4 — Looks aggressive but the knight is unstable on e4. After d3, it must retreat anyway. ♘︎d5 is much more natural.

Try this position

3. d4

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. ♘︎c3 — the Sämisch Attack, here with 3. ..♘︎xc3 4. dxc3

Center ControlSpace

3. ..d6

Challenge the head of White's pawn chain.

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.

Center ControlPawn Structure

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.

Try this position

4. ♘︎f3

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. ..♘︎b6 5. f4.

DevelopmentProphylaxis

Try this position

4. ..♗︎g4

Pin the knight that defends the e5 pawn.

♗︎g4 — 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 ♘︎xe5, White has a comfortable position. ♗︎g4 maintains pressure.

g6 — The Alburt/Fianchetto Variation — solid but less dynamic. ♗︎g4 creates immediate threats.

Try this position

5. ♗︎e2

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

DevelopmentKing Safety

Try this position

5. ..e6

Support your central knight and prepare bishop development.

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.

DevelopmentPawn Structure

Alternative Moves

♘︎c6 — Also good, developing toward the center. But e6 solidifies the ♘︎d5 first and prepares ...♗︎e7.

Try this position

6. O-O

White castles to safety. The king is secure on g1 before the central tension resolves.

King Safety

Try this position

6. ..♗︎e7

Develop your bishop and prepare to castle.

♗︎e7 — Black develops the bishop to a modest but functional square. On e7 it doesn't block any pawns and prepares kingside castling.

DevelopmentKing Safety

Alternative Moves

♘︎c6 — Develops but blocks the c-pawn. ♗︎e7 prepares castling first, keeping ...c5 options open.

Try this position

7. c4

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.

SpaceTempo

Try this position

7. ..♘︎b6

Retreat the knight to a square that still influences the center.

♘︎b6 — 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.

Piece ActivityProphylaxis

Alternative Moves

♘︎f4 — Looks active but the knight is easily kicked with g3. ♘︎b6 is stable and keeps options open.

Try this position

8. ♘︎c3

White develops the queenside knight, controlling d5. The knight on c3 adds pressure to the center.

DevelopmentCenter Control

Try this position

8. ..O-O

Get your king to safety before starting the central battle.

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.

Try this position

9. h3

White asks the bishop a question: stay, retreat, or trade? The h3 pawn forces a decision and prepares to gain the bishop pair after ♗︎xf3.

ProphylaxisTempo

Try this position

9. ..♗︎xf3

Trade the bishop before it gets pushed to a passive square.

♗︎xf3 — Black trades the bishop for the knight. This concedes the bishop pair but removes the key defender of e5. Black's position remains solid with a clear plan to attack the center.

Pawn StructurePiece Activity

Alternative Moves

♗︎h5 — Retreats but the bishop has limited scope. After g4 ♗︎g6, it gets pushed even further. Trading is cleaner.

Try this position

10. ♗︎xf3

White recaptures with the bishop, maintaining the pawn structure. The bishop on f3 is well-placed, controlling the long diagonal and supporting e4/d5 ideas.

Piece Activity

Try this position

10. ..♘︎c6

Develop your last piece to pressure White's center.

♘︎c6 — 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

♘︎8d7 — Also reasonable, rerouting toward e5 or f6. But ♘︎c6 directly attacks d4 and is more natural.

Key Takeaways

1...♘︎f6 provokes White's pawn to e5 — a hypermodern strategy
Black lets White build a center, then attacks it with ...d6
4...♗︎g4 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
