Scandinavian Defense Boehnke Gambit

Scandinavian Defense – Boehnke Gambit

Definition

The Boehnke Gambit is an aggressive branch of the Scandinavian Defense that arises after the moves 1. e4 d5 2. exd5 c6!? . Black immediately sacrifices the c-pawn (and often a second pawn) in order to seize the initiative, accelerate development, and open lines toward the white king. The gambit is named after the German theoretician Dr. Kurt (or Karl) Böhne/Böhneke, who analysed it in the early 20th century.

Basic Move Order

The most common path is:

  1. e4 d5
  2. exd5 c6 (Black offers the c-pawn)
  3. dxc6 Nxc6 (Black recaptures with a knight, already pressuring the centre)
  4. Nf3 e5 (typical follow-up; …e5 or …Bf5 & …e6 are alternative schemes)

Other sidelines include 3.d4 (declining the gambit) or 3.Nc3 Nf6 when Black maintains a fluid, open structure. A quick illustration is shown below:


Strategic Ideas & Plans

  • Rapid Development – By giving up a pawn, Black brings both knights to active posts (Nc6, Nf6) and often follows with …Bf5, …e6, and castling long, generating immediate piece play.
  • Central & Kingside Pressure – The lever …e5 (or occasionally …e6) hits the white centre. If White castles kingside, Black may launch a pawn-storm with …h5–h4 or sacrifice on g3.
  • Open Files – After the typical exchange on d5 and later …exd4, the e- and d-files open, giving the black rooks powerful avenues.
  • Endgame Outlook – If the middlegame complications fade, the extra pawn often tells for White; therefore Black aims to keep pieces on and maintain tension.

Theory Status (2020s)

Engine evaluations hover between +0.5 and +1.0 for White in the main lines, so the gambit is objectively dubious but playable. Its surprise value, however, makes it a dangerous weapon in rapid, blitz, and over-the-board club play.

Historical Notes

  • The initial printed analysis is attributed to Dr. Kurt Böhneke in the German periodical Deutsche Schachzeitung (1930s).
  • In older English sources you may also see the spellings Böehnke, Boehnke, or simply the Scandinavian Gambit.
  • Grandmasters such as Bent Larsen and Ulf Andersson experimented with it in the 1970s correspondence scene, though rarely over-the-board.

Illustrative Games

  1. Michael Basman – David LeMoir, British League 1981
    Result: 0-1
    Basman, a creative attacker himself, was lured into accepting the pawn. LeMoir’s swift …Qb6 …e5 …Bc5 left White’s king stranded in the centre.
  2. Gawain Jones – Simon Williams, London Classic Blitz 2016
    Result: ½-½
    A modern, high-speed skirmish in which Black’s pawn sac netted a time advantage but Jones steered the game into a perpetual check.

Typical Continuation (after 3.dxc6)

A model attacking blueprint for Black: 

1. e4  d5
2. exd5 c6
3. dxc6 Nxc6
4. Nc3 Nf6
5. Nf3   Bg4
6. Be2   e6
7. d3    Qc7
8. h3    Bf5
9. O-O   O-O-O

With kings castled on opposite wings, both sides race pawns forward — White on the queenside, Black on the kingside and through the centre.

Pros & Cons

  • + Surprise Value – Rarely seen at master level; most theory-heavy opponents are thrown out of book on move 2.
  • + Initiative – Black’s pieces hit the board quickly; White must tread carefully to neutralise the pressure.
  • − Objective Soundness – Engines give White a small but stable edge with best play.
  • − Endgame Risks – If the attack fizzles, Black is simply a pawn down.

Practical Tips

  1. After 3.dxc6 Nxc6, avoid slow moves like Be2; either strike back in the centre with d4 or return the pawn with c3 to complete development.
  2. Black players should learn typical mating patterns against a castled white king: sacrifices on h3 and g2, queen lifts to h4, and rook swings via h6.
  3. In blitz, the line 4.Nf3 e5 5.Bb5 e4!? poses difficult practical problems for White despite analytical objections.

Interesting Facts & Anecdotes

  • Many databases incorrectly label the Boehnke Gambit as the Icelandic-Palme Gambit; the latter actually arises from 1.e4 d5 2.exd5 Nf6 3.d4 e6.
  • In the early Internet Chess Club days, the handle DrBoehnke popularised the gambit in bullet chess, winning hundreds of games with flashy queen sacrifices.
  • Bent Larsen once remarked, The pawn on c6 is a small price to pay for the right to annoy theoreticians.

Conclusion

The Boehnke Gambit is not objectively sound, yet it embodies the romantic spirit of open-game pawn sacs: fast development, open lines, and the promise of a whirlwind attack. For players who enjoy sharp play and are willing to study the critical continuations, it can be a valuable surprise weapon in rapid and club play.
