Benko Gambit
A respected pawn sacrifice for Black: give up the b-pawn for long-lasting, easy-to-play pressure on the queenside.
The Benko Gambit (1.d4 Nf6 2.c4 c5 3.d5 b5) is one of the most respected pawn sacrifices in chess. Black offers the b-pawn to open the a- and b-files and obtain long-lasting, easy-to-play pressure against White’s queenside.
What makes the Benko special is how clear and durable the compensation is: even if White holds the extra pawn, Black’s rooks on the open files and the dark-squared bishop on the long diagonal (after …g6, …Bg7) give full value, often persisting all the way into the endgame. It is prized as a strategically clear, low-risk gambit — Black always knows the plan, while White has to defend precisely.
Main lines
- 1.d4 Nf6 2.c4 c5 3.d5 b5 4.cxb5 a6 5.bxa6The Accepted Benko — White takes the pawn; Black gets the classic queenside file pressure in return.
- 4.cxb5 a6 5.b6The Return — White hands the pawn back to blunt Black’s play; solid but less testing.
- 4.cxb5 a6 5.bxa6 Bxa6 6.Nc3 d6 7.e4 Bxf1 8.Kxf1The King-walk main line — White keeps the pawn and forfeits castling; the critical theoretical test.
- 4.Nf3A declining move order — White sidesteps the main gambit lines and keeps things flexible.
Key plans & ideas
- Open the queenside: after 4.cxb5 a6 the a- and b-files open whether White captures on a6 or Black recaptures with …axb5.
- Fianchetto and press: …g6 and …Bg7 hit d4 and the long diagonal; …Qa5 (or …Qb6) and …Rfb8 pile up on the queenside.
- Play for pressure, not material: Black aims at White’s loose queenside rather than rushing to regain the pawn.
- Trade into good endgames: the file pressure often outlasts the queens — the Benko endgame is a known plus.
- Stay alert to White’s centre: if White pushes e4–e5 or plays for a kingside initiative, react accurately.

Frequently asked questions
Is the Benko Gambit sound?
Yes — it is one of the most respected gambits. Even when White keeps the extra pawn, Black’s pressure on the open a- and b-files and the long diagonal gives long-lasting, fully playable compensation.
What does Black get for the pawn in the Benko Gambit?
Open a- and b-files for the rooks, lasting pressure on White’s queenside, and the long-diagonal bishop after …g6/…Bg7 — with very clear, repeatable plans that often carry into a favourable endgame.
Is the Benko Gambit good for beginners?
It is a great practical choice: the plans are clear and repeatable, so you play on understanding rather than memorising long forcing lines. White, by contrast, has to defend accurately.
How does White avoid the Benko Gambit?
White can decline with moves like 4.Nf3 or 4.a4, or return the pawn with 5.b6 to reduce Black’s pressure. Accepting fully with 5.bxa6 leads to the main theoretical battles.
