The Modern Benoni
1.d4 Nf6 2.c4 c5 3.d5 e6
The Modern Benoni (1.d4 Nf6 2.c4 c5 3.d5 e6) creates the most dynamic structural imbalance available against 1.d4: Black concedes central space for a queenside pawn majority, the half-open e-file and the raking g7-bishop. It is the fighting choice — Mikhail Tal used it to conjure attacks from nothing.
Mainline
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nf3 Bg7 8.Be2 O-O 9.O-O Re8
Modern Benoni: Classical Main Line (7.Nf3)
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nf3 Bg7 8.Be2 O-O 9.O-O Re8
The main road. White develops quietly and Black completes the standard Benoni setup: the g7-bishop rakes the long diagonal, the rook eyes e4 down the half-open file, and ...Na6-c7 with ...b5 is coming. Almost every Benoni idea you will ever need is already on the board in this position.
Modern Benoni: Taimanov Attack (8.Bb5+)
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.f4 Bg7 8.Bb5+
The most feared line in the whole variation. White plays f4 and inserts the check on b5 to provoke a concession before Black can castle — after ...Nfd7 the knight is passive, after ...Bd7 the bishop blocks the defence. Black must know this cold, because a single careless move order loses on the spot.
Modern Benoni: Four Pawns with Nf3
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.f4 Bg7 8.Nf3 O-O 9.Be2
White takes maximum space and plans e5 at the right moment. Black's counterplay is the standard Benoni recipe applied with more urgency: ...Re8 hitting e4, ...Na6-c7 and the ...b5 lever, plus tactical shots on the a7-g1 diagonal whenever White's centre overreaches.
Modern Benoni: Fianchetto Variation (7.g3)
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.Nf3 g6 7.g3 Bg7 8.Bg2 O-O 9.O-O
The positional test, and statistically White's most reliable. By meeting the g7-bishop with its counterpart on g2, White defuses the diagonal that fuels every Black plan. Black switches to the queenside majority and the ...b5 break, accepting a slower game where understanding matters more than sharpness.
Modern Benoni: Knight's Tour Variation
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nge2 Bg7 8.Ng3 O-O 9.Be2
White routes the knight to g3 instead of f3, keeping the f-pawn free to advance and covering e4 and f5. It is slower than the Taimanov but far less forcing, so Black gets the pawn breaks in — the trade-off is that White's kingside build-up with f4 and Be3 arrives without any tactical accidents.
Snake Benoni (5...Bd6)
1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 Bd6
A genuine surprise weapon: the bishop goes to d6 to reroute via c7 to a5 or b8, avoiding the main-line battles altogether. Objectively White keeps an edge with quiet play, but at club level almost nobody has seen it, and the resulting positions are pure Benoni in spirit — space against activity.
Key ideas
- Trade your ...e6 pawn for White's c4-pawn and inherit a rolling queenside majority.
- Activate the Benoni bishop on g7 — its pressure on the long diagonal fuels every Black plan.
- Expand with ...a6 and ...b5 while pressuring e4 down the half-open e-file with ...Re8.
- Play for the full point in every game: the imbalance guarantees winning chances for both sides.
Typical plans and structures
Black's play writes itself: ...Re8 and ...Nbd7 or ...Na6-c7 support the ...b5 break, the g7-bishop and ...Ng4 tricks generate kingside tactics, and the c5-c4 clamp or ...c4 with ...Nc5 fixes targets. White's critical tries — the pawn storms with f4 or the modern h3 and Bd3 setups — demand accuracy, and the course focuses its deepest preparation exactly there. Endgames with the queenside majority rolling are a recurring Benoni happy ending.
Who should play it
Dynamic players who accept structural risk for piece activity and want a defense to 1.d4 that fights for the win from move three.

Frequently asked questions
Is the Modern Benoni sound?
It is theoretically respectable but demands precision: White's space and central majority are real, and a passive Benoni is a bad Benoni. Played actively — with the plans this course drills — it has served attacking legends from Tal to Topalov to Gashimov.
What is White's most dangerous setup against the Modern Benoni?
The critical tests are the Flick-Knife (Taimanov) Attack with f4 and Bb5+ and the modern h3-Bd3 system. Both try to punish Black before the queenside majority matters — which is why a serious Benoni repertoire is built around meeting exactly these lines.
How is the Modern Benoni different from the Old Benoni?
The Modern Benoni inserts ...Nf6 and ...e6 before committing, exchanging on d5 to create the classic majority structure with maximum piece activity. The Old Benoni (1.d4 c5) commits immediately, often leading to closed positions with far less theory for both sides.
