Bird's Opening, Dutch Defence, Sturm Gambit
Bird’s Opening
Definition
Bird’s Opening is the chess opening that begins with the move 1. f4. Named for the 19th-century English master Henry Edward Bird, it immediately claims a share of the center (the e5-square) and prepares potential kingside expansion. In ECO it occupies codes A02–A03.
How it is used in play
- Reversed Dutch. After 1…d5 or 1…f5, the resulting positions resemble a Dutch Defence with colors switched, giving White an extra tempo.
- Flexible development. White can adopt a Stonewall (d4, e3, Nf3, Bd3) or a Leningrad-style set-up (g3, Bg2, 0-0) according to Black’s reply.
- Attacking chances. The f-pawn is already advanced, so pushes like f5 or sacrifices on g6 often arise quickly.
Strategic significance
Because 1. f4 weakens the king and does not fight immediately for d4, the opening is considered sound but slightly risky. It often attracts players who enjoy unbalanced positions and are comfortable with asymmetrical pawn structures.
Illustrative examples
- Bird – Morphy, London 1858
Bird’s adventurous opening met Morphy’s energetic style. Although Bird lost, the game showcased rapid piece activity for both sides and cemented the opening’s reputation for excitement. - T. Petrosian – Spassky, Moscow 1956 (Training match)
The future World Champion used a Leningrad structure with colors reversed and obtained a stable but active position, demonstrating that Bird’s Opening can be played at the highest level.
Miniature for visualization:
Notice how the early f-pawn push leads to razor-sharp tactics around both kings.
Interesting facts & anecdotes
- Henry Bird was so committed to 1. f4 that he once played it both with White and with Black (after replying 1…f5) in the same tournament round.
- The legendary Emanuel Lasker occasionally rolled out Bird’s Opening in simultaneous exhibitions, praising its “psychological” value in surprising opponents.
- In computer chess, engines evaluate 1. f4 roughly half a pawn below 1. e4 or 1. d4, but several modern neural-network programs have revived interest by uncovering new resources in the Leningrad set-up.
Dutch Defence
Definition
The Dutch Defence arises after 1. d4 f5. Black forgoes classical symmetry in order to seize the e4-square and aim for a kingside initiative. The opening’s ECO codes are A80–A99, covering a broad set of pawn structures and plans.
Main variations
- Classical (A90). …e6, …Nf6, …Be7/Bb4 give a solid but flexible set-up.
- Leningrad (A81–A88). …g6 and …Bg7 produce a dynamic fianchetto; often likened to a King’s Indian with the c-pawn still on c7.
- Stonewall (A95–A97). …d5, …e6, …c6 create the famous “Stonewall” pawn chain (f5-e6-d5-c6) providing space and a potential e4-push.
- Anti-Dutch systems. White can reply with 2. Bg5 (Staunton), 2. g3, the Raphael (2. Nc3), or the Queen’s Indian–style 2. Nf3 Nf6 3. g3.
Strategic themes
- Control of e4. Black’s central motif is the pawn on f5, supporting …e5 or restraining White’s e4 advance.
- Kingside attack. Typical maneuvers include …Qe8–h5, …Rf6–h6, and sacrifices on g3/h2.
- Structural commitments. The same pawn on f5 weakens the diagonal a2–g8 and the e6-square, demanding accurate defense.
Historical context
The Dutch was analyzed as early as the 18th century by Elias Stein of The Hague, whose treatise advocated 1…f5 against 1. d4. World Champions Alekhine and Botvinnik employed it occasionally, while contemporary specialists include Hikaru Nakamura and GM Vladimir Malakhov. Its double-edged nature makes it popular in must-win situations.
Famous games
- Botvinnik – Bronstein, World Championship 1951, Game 11: Bronstein’s Leningrad set-up nearly brought him victory with a fierce kingside assault.
- Nakamura – Carlsen, London Classic 2011: A tense Classical Dutch where Carlsen neutralized Nakamura’s pressure to draw an endgame a pawn down.
- Short – Timman, Tilburg 1991: Short’s g2-g4 pawn storm crushed the Stonewall in one of the most instructive “anti-Dutch” victories.
Interesting facts & anecdotes
- The Dutch is one of the few mainstream defenses that deliberately weakens Black’s own king on move 1, yet its surprise value has converted many must-win games.
- In the 1997 Kasparov–Deep Blue match, the IBM team programmed the computer with a special anti-Dutch module, fearful Kasparov might unleash the line in a decisive final game.
- GM Bent Larsen, an advocate of original openings, once began 1. b3 hoping to transpose into a Dutch with colors reversed if Black mirrored …f5.
Sturm Gambit
Definition
The Sturm Gambit is a sharp pawn sacrifice that appears most commonly in Bird’s Opening after the moves 1. f4 f5 2. e4 – offering a central pawn for rapid development and open lines. In ECO it is cataloged under A02 (“Bird’s Opening: Dutch Variation, Sturm Gambit”). The same idea with colors reversed (1. d4 f5 2. e4) is sometimes called the Staunton or Little Sturm Gambit inside the Dutch Defence.
Move-order and immediate tactics
- 1. f4 f5 2. e4 fxe4 3. Qh5+ g6 4. Qe5 Nf6
White regains the pawn or forces structural concessions, thanks to the queen sortie to h5 and e5. - 1. f4 f5 2. e4 dxe4 3. d3 Nf6 4. Nc3
An alternative line where White builds a big center and quick piece play.
The key motifs are:
- Targeting the weak f7/f2 and e4/e5 squares left by the gambit capture.
- Rapid mobilization of the king’s-side pieces (Bf1-e2-h5, Ng1-f3, 0-0-0).
- Creating long-term pressure on the semi-open f-file, often doubling rooks there.
Risk versus reward
Engines judge the gambit as objectively dubious (≈ +0.7 – +1.0 for the defender with best play), yet practically it scores well in club events because Black can be caught off guard by the early queen incursion. If Black tries to hold the extra pawn, development often lags and tactical shots on f7/h7 become decisive.

The following 15-move game demonstrates the power of quick development:
White’s g-pawn lunge and piece activity overwhelm Black before development is complete.
Trivia & anecdotes
- The gambit is named after the German word “Sturm” (“storm”) reflecting the violent pawn storm that often follows.
- GM Michael Basman—famous for offbeat openings like 1. g4 (the Grob)—has played the Sturm Gambit in serious competition, calling it “a From Gambit you get to play with White.”
- According to the ChessBase database, the line enjoys a surprisingly respectable 53 % score for White up to the 2300 rating range, dropping sharply above 2600 as defenders find precise engine lines.
