Alekhines Defense Modern Alburt Variation
Alekhine’s Defense, Modern (Alburt) Variation
Definition
The Alekhine’s Defense, Modern (Alburt) Variation is a branch of the Alekhine’s Defense that begins with the moves:
- 1. e4 Nf6
- 2. e5 Nd5
- 3. d4 d6
- 4. Nf3 g6 (Modern Variation)
- 5. Bc4 Nb6
- 6. Bb3 Bg7 (Alburt line)
Named after Grandmaster Alex Y. Alburt, the variation combines the hyper-modern principles of the Alekhine (provoking an over-extended white center) with a kingside fianchetto, aiming for dynamic counterplay rather than immediate confrontation in the center.
Typical Move Order and Key Position
One common waypoint is reached after:
1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 g6 5. Bc4 Nb6 6. Bb3 Bg7 7. Qe2
Black’s knight on b6 eyes c4 and d5, the bishop on g7 pressures the center, and White maintains a broad pawn phalanx on e5 and d4. The FEN of this sample position is:
rnbqk2r/ppp1ppbp/1n1p1np1/4P3/3P4/1B3N2/PPP1QPP1/RNB1K2R b KQkq - 3 7
Strategic Themes
- Hyper-modern Counterplay: Black invites White to occupy the center and plans to undermine it later with …dxe5, …c5, or …Bg4.
- Queenside Knight Maneuvers: The knight shuffles from d5 to b6 (or occasionally to b4/c7) to harass White’s center and light-squared bishop.
- Central Tension: The e5–d4 pawns give White space but can become static weaknesses if Black achieves …c5 or …dxe5 at the right moment.
- Flexible Pawn Breaks: Black’s …f6, …dxe5, and …c5 are the usual levers; White counters with c4, e6 (pawn sac), or h4–h5.
Main Plans
For White
- Maintain the strong pawn on e5 and support it with f4 or c4.
- Develop pieces quickly (Nc3, Qe2, 0-0, Rd1) to meet …c5 with d5.
- Consider kingside expansion with h4–h5 if Black castles short.
- Avoid premature pawn breaks that could open lines for Black’s bishops.
For Black
- Castle short, place rooks on e8 and c8 (after …c5) for central pressure.
- Exchange the dark-squared bishop if possible (…Bg4 or …Be6) to reduce White’s central grip.
- Strike at White’s center with …dxe5, …c5, or …f6 when tactically justified.
- Watch out for the thematic pawn sacrifice e6 by White, which can rip open the f7-square.
Historical Significance
The Modern line (4…g6) appeared in the 1920s, but it was Alex Alburt in the 1970s-80s who systematized 5.Bc4 Nb6 6.Bb3 Bg7 as a reliable fighting weapon for Black. Alburt used it extensively in U.S. Championships and international play, earning the line its double-barreled name. Its reputation rose further after being adopted by players such as Grandmasters Vassily Ivanchuk and Vladimir Bagirov.
Illustrative Games
- Karpov – Alburt, USSR Championship, Leningrad 1971: Alburt demonstrated the viability of the setup, equalizing comfortably and later winning in a complex endgame.
- Ivanchuk – Morozevich, Linares 1995: Showcases Black’s thematic …c5 break, leading to a double-edged middlegame.

Interesting Facts & Anecdotes
- Surprise Weapon: Because the Modern–Alburt line is less common than the Classical or Four Pawns lines of the Alekhine, it often serves as a practical surprise at club and tournament levels.
- Transpositional Potential: The setup can transpose into Pirc-like or Modern Defense structures after …dxe5 and …c6, giving Black flexibility to steer the game away from an opponent’s preparation.
- “Poisoned” Pawn on e5: In several grandmaster games, impatient captures on e5 by Black led to disaster; timing is everything in undermining White’s center.
- Alburt’s Book Influence: Alburt’s co-authored “Chess Openings for White, Explained” dedicates an entire chapter to combating his own system from the White side—a rare case of an opening’s namesake showing readers how to beat it!
When to Choose the Alburt Variation
Players who enjoy:
- Unbalanced, dynamic positions with counter-attacking chances.
- Hyper-modern openings where piece play trumps immediate pawn control.
- Lines that sidestep the heavily analyzed Four Pawns and Exchange Variations.
…will find the Modern (Alburt) Variation of Alekhine’s Defense a stimulating and practical choice.
