Alekhines Defense & Buntin Gambit
Alekhine’s Defense
Definition & Basic Move-Order
Alekhine’s Defense is an unorthodox reply to the King’s Pawn opening that begins 1. e4 Nf6. By immediately attacking White’s central pawn with the knight, Black invites the pawn to advance and overextend, hoping to undermine it later. This defense is named after the fourth World Champion, Alexander Alekhine, who introduced it into top-level practice in the early 1920s.
Strategic Ideas
- Provocation. Black tempts the e-pawn forward to e5, then attacks the enlarged white center with timely …d6, …c5, and piece pressure.
- Dynamic Imbalance. Black concedes space in the opening in return for a lead in development and long-term counter-punching chances.
- Piece Play. Because the Black knight has already moved twice, both sides are quickly forced into concrete play rather than slow maneuvering.
Main Variations
- Exchange Variation: 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.exd6 cxd6.
- Four Pawns Attack: 2.e5 Nd5 3.d4 d6 4.c4 Nb6 5.f4 — White grabs maximum space; Black aims at the center with …g6 and …Bg7.
- Modern Variation: 2.e5 Nd5 3.d4 d6 4.Nf3 g6.
- Two Pawns Attack (2.Nc3): White avoids immediate e5 and keeps options open.
- Exchange-Deferred (4…Qxd6) Lines: Black recaptures with the queen instead of the pawn, seizing quick central activity at the cost of tempi.
Historical Significance
The defense debuted in master play in 1921 when Alekhine defeated Endre Steiner in Budapest. Although never as popular as the Sicilian or French, it has remained a respected surprise weapon. Notable modern practitioners include Viktor Korchnoi, Vassily Ivanchuk, and—on occasion—Magnus Carlsen.

Interesting Facts & Anecdotes
- Alekhine reportedly analyzed the opening while serving in the Russian army hospital during World War I.
- Bobby Fischer employed Alekhine’s Defense twice in the 1970 Interzonal at Palma de Mallorca, winning both games.
- The line has appeared in correspondence and engine chess far more often than in classical time-controls, where the margin for mistake in defending a cramped position is smaller. [[Chart|Rating|Classical|2000-2023]]
Buntin Gambit
Definition & Basic Move-Order
The Buntin Gambit is an off-beat, sacrificial line in the Caro-Kann Defense that arises after:
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.f3!?
With 4.f3 White immediately offers a pawn to accelerate development, open the f-file, and steer the normally solid Caro-Kann into sharp tactical channels. The gambit is named after American correspondence master James F. Buntin, who analyzed and championed the idea in the early 1970s.
Strategic Ideas
- Piece Activity over Material. After 4…exf3 5.Nxf3, White’s pieces flood the center while Black’s queenside remains undeveloped.
- Open f-file. Castling kingside puts a rook on f1, pointing straight at Black’s king, especially potent if Black plays …e6.
- Psychological Surprise. Caro-Kann players expect a slow, positional game; the Buntin Gambit forces them to calculate from move 4.
Theory Snapshot
- Main Line: 4…exf3 5.Nxf3 Nf6 6.Bc4 Bf5 7.O-O e6 8.Ne5 Bg6 9.g4!?
- Declined: 4…Nf6 5.fxe4 e5!? — a French-like structure where White keeps a space advantage.
- Immediate Counter: 4…Bf5? 5.fxe4 Bg6 6.Nf3 e6 7.Bd3 with a big lead in development.
Historical & Practical Significance
While never mainstream, the gambit has scored well in club, blitz, and correspondence play, where preparation is limited. Early analysis appeared in the magazine Chess Horizons (1973), and the line was later explored by International Master John Watson in his annotations on unorthodox openings.

Interesting Facts & Anecdotes
- Because 4.f3 resembles the Blackmar-Diemer Gambit (1.d4 d5 2.e4), some players call it “the Blackmar-Diemer of the Caro-Kann.”
- The first over-the-board master game featuring the gambit was G. Gresser – J. Zimmermann, U.S. Open 1980, which ended in a 24-move attacking win for White.
- Modern engines give the gambit roughly +0.30 after best play—objectively sounder than its reputation suggests.
