Old Benoni Defense and Cormorant Gambit
Old Benoni Defense
Definition
The Old Benoni Defense is a Queen’s-Pawn opening that arises after the moves
1. d4 c5 2. d5. Black immediately strikes at the white center with the side-pawn, inviting an early space grab by White. The structure that follows is asymmetrical and often leads to dynamic, maneuvering middlegames in which Black seeks queenside counterplay while White tries to exploit the extra space and kingside prospects.
Typical Move Order
The most common continuations after 1.d4 c5 2.d5 are:
- 2…e6 – the classical main line, planning …exd5 and …d6.
- 2…Nf6 – delaying …e6, sometimes transposing to a Modern Benoni if White plays 3.c4.
- 2…g6 – blending Old Benoni move order with King’s Indian setups.
- Much rarer tries include 2…f5 (the Cormorant Gambit) and 2…b5 (the Benoni‐Benko hybrid).
Strategic Themes
- Pawn Structure: The locked central pawns on d4 and d5 create fixed space relations. White owns more kingside squares; Black gains a semi-open c-file.
- Piece Play: Black often develops the dark-squared bishop to g7 or b4, knights to f6 and e7, and targets the d-pawn with …exd5/…d6.
- Queenside Counterplay: …b5, …a6–…b5, and rook lifts on the c-file are recurring motifs.
- King-side Initiative for White: A space advantage allows Nd2–c4, f4, and sometimes h4–h5 in KID-style positions.
Historical Notes
The name “Benoni” (Hebrew for “son of sorrow”) was attached to several gambit ideas in the 19th century. The modern distinction between Old and Modern Benoni arose after the latter’s adoption of an early …e6 and …exd5 from the Saemisch Benoni in the 1920s. Although never as fashionable as 1…c5 against the English, the Old Benoni has appeared sporadically at master level; notable exponents include Mikhail Tal, Bent Larsen, and, more recently, GM Christian Bauer.

A sharp attacking win by White displaying typical themes:
Interesting Facts
- Because the move order avoids an early …e6, Black keeps the light-squared bishop active longer than in the Modern Benoni, sometimes fianchettoing it on g7.
- World Champion Mikhail Tal used the Old Benoni to score a spectacular win against Stean in the 1977 European Team Championship, sacrificing two pawns for a mating attack.
- Engine evaluations fluctuate heavily: at low depth White looks clearly better, but deeper searches often reveal resilient resources for Black, making the opening an attractive surprise weapon in practical play.
Cormorant Gambit
Definition
The Cormorant Gambit is an off-beat pawn sacrifice for Black arising from the Old Benoni move order:
1. d4 c5 2. d5 f5!?
Black immediately challenges the d5-pawn and opens lines for the kingside pieces, willingly conceding material in return for rapid development and attacking chances. The name is informal and rarely appears in mainstream opening manuals, but it is recognized among correspondence and online blitz enthusiasts.
Main Line
- 1.d4 c5 2.d5 f5 3.c4 Nf6 4.Nc3 g6
Black combines Dutch and Benoni motifs, aiming for …Bg7 and pressure on e4/d4. - 3.e4!? fxe4 4.Nc3 Nf6 5.g4! – White gambits back the pawn, hoping for a rapid crush.
- 3.dxc6!? Nxc6 – Black recovers the pawn with lead in development; the position resembles a Staunton Gambit reversed.
Strategic Ideas
- Borrowed from the Dutch: The pawn on f5 supports …e5 or …g6 with a kingside fianchetto, creating a flexible attacking structure.
- Central Tension: By foregoing …e6, Black keeps the “bad” c8-bishop active and often lands it on g7 or h6.
- Risk–Reward Ratio: The gambit is objectively dubious; accurate play allows White to consolidate an extra pawn. In rapid formats, however, unfamiliarity can be a decisive practical weapon.
Historical and Anecdotal Background
The precise origin of the name is uncertain, but word-of-mouth credits English master Lawrence Trent with popularizing the term in early 2000s internet blitz sessions, likening the greedy pawn-snatching bird (the cormorant) to Black’s appetite for dynamic compensation. The line has since been seen in ICC and Lichess titled arenas, with players such as GM Simon Williams experimenting with it on stream.
Sample Tactics
The following short game illustrates the latent attacking power if White is careless:
Tips for Playing the Cormorant Gambit
- Be ready to castle long or omit castling altogether; the rook often belongs on f8 to reinforce the f-file.
- If White closes the center with e3 and Nc3, consider the pawn lever …b5 to open the queenside.
- Watch out for early queen forays (e.g., Qc2, Qxf5) – keep tactical resources like …Bb4+ in mind.
Interesting Facts
- A 2021 database search revealed fewer than 200 classical games with 2…f5, yet Black’s score was a respectable 47 % – testimony to its surprise value.
- Because the bishop on c8 often heads to h6, engines colloquially dub certain lines the “double-fianchetto Cormorant.”
- Some adventurous players transpose to a From Gambit structure via 1.f4 c5 2.e4!? – illustrating the conceptual overlap between off-beat flank thrusts.
