Budapest Gambit Fajarowicz Variation
Budapest Gambit – Fajarowicz Variation
Definition
The Fajarowicz Variation is an aggressive sideline of the Budapest Gambit that arises after the moves 1. d4 Nf6 2. c4 e5 3. dxe5 Ne4. Instead of the more common 3…Ng4 (the Adler Line), Black immediately posts the knight in the centre on e4, aiming to seize the initiative, accelerate piece development, and unbalance the position at the cost of a pawn.
Move-order table
The critical branching point occurs on move 4:
- 4. a3 – the main try, preventing …Bb4+.
- 4. Nf3 – develops naturally, inviting …d6 or …Bb4+.
- 4. a3?! – sometimes transposes, but gives Black tactical chances.
- 4. Qc2 / 4. g3 / 4. Nd2 – quieter systems in which White protects the e4-square or prepares to undermine the knight indirectly.
Strategic themes and typical ideas
- Central tension: Black’s knight on e4 is temporarily unsupported but annoyingly placed. White must decide whether to chase it with f2–f3, undermine it with Nd2, or simply ignore it and race ahead in development.
- …Bb4+ fork motif: After 4.Nf3 or 4.Qc2, Black often plays …Bb4+, aiming at c3 and e4 simultaneously. Should White block with Nbd2, Black may recapture on d2 and regain the pawn with favourable piece activity.
- Rapid mobilization: Moves like …d6, …Nc6, …Bf5, and castling short place Black’s pieces on active squares while White’s queen-side development lags.
- Long-term pawn structure: If Black fails to recover the pawn, the e-pawn deficiency can become serious in a simplified endgame. Conversely, once the pawn is regained, the open centre frequently favours Black’s better-coordinated pieces.
Historical background
The line is named after the Polish master Stefan Fajarowicz, who employed it with success in tournament play in the late 1920s. It quickly earned a reputation for surprise value; many classical players were reluctant to enter the complications from the Black side, so theory developed slowly.
Although the variation never reached the very top level with consistent use, it has remained a favourite of enterprising masters and club players who enjoy tactical play and are willing to accept certain positional risks for practical chances.
Illustrative miniature
The following game shows how quickly Black’s pieces can spring to life if White is careless:

Practical tips
- Be ready for heavy piece exchanges on d2 and c3; keep tactical alertness high.
- If playing Black, memorise a forcing line against 4.a3, as that is the critical antidote. The sequence 4…b6 5.Nf3 Bb7 6.Nbd2 a5 gives Black a solid platform for queenside counterplay.
- As White, avoid passive manoeuvres; the extra pawn alone rarely decides the game if Black’s piece activity is unhindered.
Interesting facts
- The variation once enjoyed a cult following in correspondence chess, where analytical depth often allowed Black to “refute” sub-optimal White set-ups and score well above expectation.
- Some engines initially evaluate the position after 3…Ne4 as clearly better for White (≈ +1), yet in fast time controls Black’s initiative tends to compensate fully, illustrating the difference between static evaluation and dynamic potential.
- Grandmaster Alexander Morozevich briefly used the Fajarowicz as a surprise weapon in online blitz, achieving an impressive of 2876 during that period.
Why study the Fajarowicz?
For the enterprising player, the line offers:
- Practical chances against unprepared opponents.
- Rich tactical motifs that sharpen calculating skills.
- An off-beat but theoretically sound weapon that avoids the mass of mainline theory in Queen’s Gambit Declined and Nimzo-Indian systems.
