Modern Defense: Three Pawns Attack
Modern Defense – Three Pawns Attack
Definition
The Three Pawns Attack is an aggressive anti-Modern system in which White erects an impressive pawn phalanx on e4, d4, and f4. The name refers to those three advanced central pawns that gain spatial dominance and announce an early intention to attack. The usual move-order is:
1. e4 g6 2. d4 Bg7 3. Nc3 d6 4. f4
Technically the same structure can arise from many related openings (the Pirc, the King’s Indian vs. 1.d4, or even some Dutch lines), but when Black has already fianchettoed the king’s bishop on g7 and delayed …Nf6, theory classifies the position as “Modern Defense: Three Pawns Attack.” ECO codes B06–B07 are the most common references.
Strategic Essence
- Space & Initiative. White seizes the centre, often restricting Black’s pieces and preparing a kingside storm with moves such as e5, f5, or g4–g5.
- Dynamic Imbalance. Black accepts less space in exchange for flexibility: the fianchettoed bishop, delayed development (especially …Nf6), and early pawn breaks …c5 or …e5.
- Pawn Structure. The e4–d4–f4 chain resembles the Austrian Attack in the Pirc; the major difference is that Black’s knight may arrive on h6 (instead of the usual f6), and …a6/…b5 setups are more common than in the Pirc.
- King Safety. White usually castles short but keeps the rook on f1 ready to support f5. Black almost always castles kingside, trusting dark-square control and counterplay in the centre or on the queenside.
Main Line Move-Order
- e4 g6
- d4 Bg7
- Nc3 d6 (Black can also test 3…c6 or 3…d5 but 3…d6 is theoretically central)
- f4 (the signature move)
- …Nf6 or …a6 (two principal branches)
Typical Plans for White
- Advance the e-pawn to e5, gaining space and chasing the f6-knight (if present).
- Play Nf3, Bd3, Qe2, 0-0, and then f5 or sometimes g4–g5.
- In some variations sacrifice a pawn with e5 dxe5 fxe5 to open the f-file against Black’s king.
- If Black closes the centre with …e5, White can pivot to a queenside minority attack with b4 or c5 breaks.
Typical Plans for Black
- Break with …c5 or …e5 at the right moment to undermine White’s pawn chain.
- “Modern” pawn storm on the queenside: …a6, …b5, …Bb7, and sometimes …Nd7–b6, hitting c4.
- Maintain the strong bishop on g7, often the key defender and counter-attacker.
- Exploit the long-diagonal with moves like …Qb6 or …Qb6+ (if c4 has been played).
Historical & Theoretical Significance
The Modern Defense rose to prominence in the 1950s under the influence of grandmasters such as Bent Larsen and Duncan Suttles, who showed that delaying …Nf6 could create fresh strategic motifs. The Three Pawns Attack, first explored seriously in the 1960s, became a favourite of players who enjoyed the Austrian Attack against the Pirc but wanted to sidestep Black’s heavy Pirc theory. GM Viktor Korchnoi used it with success in the 1970s, and in modern times it remains a sharp weapon at club and grandmaster level alike.

Key moments:
- 16.e5! rips open the centre while the king on g8 is still vulnerable.
- 22.Nxa8! shows how White’s space advantage can morph into tactical gains.
Interesting Facts & Anecdotes
- Nicknames. Older British texts sometimes call this line “The Bayonet Attack” (not to be confused with the 9.b4 line vs the King’s Indian).
- Computer Approval. Modern engines often hover near equality but still evaluate positions after 4.f4 as “+0.30” for White—high praise given Black’s theoretical resilience.
- Bent Larsen’s Surprise. In the 1974 Nice Olympiad, Larsen sprung 4.f4 against GM András Adorján and won a sparkling attacking game that ended with a queen sacrifice and mate on move 31.
Related Openings & Transpositions
- Austrian Attack in the Pirc: 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4.
- Four Pawns Attack vs King’s Indian: 1.d4 Nf6 2.c4 g6 3.e4 d6 4.f4.
- Modern Defense Averbakh Variation: 1.e4 g6 2.d4 Bg7 3.c4, which can transpose into the Three Pawns Attack if White later adds f4.
Common Tactical Motifs
- e4–e5 Break. Opening the f-file or forcing Black pieces into awkward squares.
- g2–g4–g5. Overrunning the knight on f6 or gaining kingside space.
- Sacrificial Themes: Bxf7+, Nxf7, or sometimes f5 gxf5 exf5 to shatter Black’s pawn shield.
Conclusion
The Modern Defense – Three Pawns Attack is a forceful, strategically rich system that rewards precise calculation and creative thinking. It offers practical chances for both sides: White enjoys immediate space and attacking prospects, while Black gains unbalanced positions ripe for counterplay. Whether you are a Modern aficionado looking for a fresh battleground or a white-side initiative seeker, this line remains a compelling choice in contemporary chess.
