After 1.d4 Nf6 2.c4 c5 3.d5, Black invites one of the sharpest pawn structures in chess. The Benoni is not one opening but a family: the Modern Benoni (3…e6), the Benko (or Volga) Gambit (3…b5), the Czech Benoni (3…e5) and assorted move-orders, all going for asymmetry and counterplay rather than equality. In a single 1.d4 game White can be asked any of these questions — and at master level the most common reply is not the Modern Benoni at all but the Benko Gambit, almost half of all answers to 3.d5.

The good news for White is that you do not need a different opening for each — you need one coherent set of plans. This guide, written for White, builds a complete weapon against everything after 2…c5. Versus the Modern Benoni it offers four reliable systems — the Modern Main Line 7.h3 (recommended, the best-scoring modern try), the sharp Taimanov 7.f4, the natural Classical 7.Nf3 and the low-theory Fianchetto with g3 — and it gives a full answer to the Benko (accept with 5.bxa6, 5.e3 or 5.b6, or decline with 4.Nf3) and to the closed Czech Benoni (4.Nc3 and e4). Pick the system that suits your style; the rest of the structure stays the same.

Main lines

1.d4 Nf6 2.c4 c5 3.d5The Benoni starting position; Black chooses 3…e6 (Modern Benoni), 3…b5 (Benko), 3…e5 (Czech) or 3…g6 — White meets all of them from here.
3…e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.h3The Modern Main Line (recommended): h3 prevents …Bg4 and prepares Bd3 and Nf3; the best-scoring modern setup against the Modern Benoni.
6.e4 g6 7.f4The Taimanov — the most popular and most testing try, gaining space; …Bg7 8.Bb5+ is the critical line.
3…b5 4.cxb5 a6 5.e3Anti-Benko, the Modern line: White returns the pawn and develops quickly — the best practical score against the Benko. 5.bxa6 (take everything) and 5.b6 (return it at once) are the alternatives.
3…b5 4.Nf3Benko Declined — White keeps the structure intact and develops, sidestepping the theory of the accepted gambit.
3…e5 4.Nc3 d6 5.e4The Czech Benoni — a closed, manoeuvring battle; White plays h3, Bd3 and prepares the g4 break.

Key plans & ideas

Recommended versus the Modern Benoni — the Modern Main Line: after 3…e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.h3, the little luft stops …Bg4 before White commits Nf3 and Bd3. It scores best for White in master practice and keeps a clean, flexible setup.
Or pick a sharper system: 7.f4 (Taimanov) grabs space and is the most testing try; 7.Nf3 with Be2 and O-O (Classical) is the natural main line; the Fianchetto with 6.Nf3 g6 7.g3, Bg2 and O-O is the quietest, lowest-theory choice.
Be ready for the Benko first: 3…b5 is Black’s most popular move, so decide your anti-Benko in advance. Take everything with 5.bxa6 (Fully Accepted), return the pawn with 5.e3 (the best-scoring Modern line) or 5.b6 (Pawn Return), or sidestep the theory with 4.Nf3 (Benko Declined).
Meet the Czech (3…e5) by closing the centre: 4.Nc3 d6 5.e4 and a slow build-up with h3, Bd3 and a prepared g4 — there are no forcing lines, so out-manoeuvre Black rather than rush.
Know the Benoni middlegame: hold the d5-wedge, watch the e4-square and the long diagonal of Black’s g7-bishop, and answer …b5 breaks calmly. The thematic e4-e5 break is strong only when prepared — don’t push it into Black’s pieces.
Mind the a6-bishop in the Benko: it eyes f1 along the a6–f1 diagonal, so a knight lunge to b5 simply drops to …Bxb5 — develop and castle by hand instead.

Frequently asked questions

Is the Benoni sound?

The Benoni complex is fully playable and a favourite of attacking players — Black accepts a space disadvantage for active piece play and queenside counterplay. White is not trying to refute it but to choose a comfortable system; with accurate play White keeps a small, lasting pull and the safer position.

How does White play against the Modern Benoni?

Pick one system and learn its plan. The recommended choice is the Modern Main Line: 6.e4 g6 7.h3 followed by Bd3 and Nf3, which scores best in master practice. The sharp 7.f4 (Taimanov), the natural 7.Nf3 (Classical) and the quiet g3 fianchetto are the main alternatives.

How should White meet the Benko Gambit?

Decide in advance, because 3…b5 is Black’s most common reply after 3.d5. You can accept with 5.bxa6 (the principled Fully Accepted), return the pawn with 5.e3 (the best-scoring Modern line) or 5.b6 (Pawn Return), or decline with 4.Nf3 to avoid the accepted-gambit theory.

What is the best move against the Benoni?

There is no single refutation. Against the Modern Benoni the modern top choice is the Main Line with 7.h3; against the Benko, 5.e3 gives White the best practical results. The right answer is the system that matches your style — sharp (7.f4 / 5.bxa6) or solid (g3 / 4.Nf3).

What about the Czech Benoni (3…e5)?

Close the centre with 4.Nc3 d6 5.e4 and play a patient manoeuvring game — h3, Bd3 and a prepared g4 advance. There are no forcing lines; White has more space and should avoid loosening moves such as the careless Bf4, which simply drops to …exf4.
