The Modern Benoni: 1.d4 Nf6 2.c4... 0-0 begins with 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nf3 Bg7 8.Be2 0-0 (ECO A72). Across rating levels it shows up in 121,262 recorded games — enough data to map exactly where it succeeds and where it stalls.
History and Notable Players

Performance Across Rating Levels
The picture changes a lot as you climb the rating ladder. At 1200 Elo, the opening shows up in 0.00% of games (443 samples). White scores 51.2%, Black 47%, draws 1.8%. By 1800, popularity is 0.00% and White's score is 46.5% to Black's 49%. At the top end (2500+ Elo), popularity is 0.02% with 8.5% draws — a clear sign of how much theory rules the line at master level. White's edge erodes by 4.2pp from 1200 to 2500 Elo, suggesting Black's counterplay is easier to find with experience.
Move Diversity and Theory Depth
Looking at move selection shows how forcing — or not — the position really is. At 1200 Elo, the top reply is O-O, played 82.9% of the time. There are 2 other moves seeing meaningful share, and 92.5% of games stick to established theory. Entropy: 1.15. By 2500, O-O dominates at 62.9% of replies; only 3 viable alternatives remain and 93.4% of moves are theory. Entropy drops to 1.61. Move diversity stays high even at master level, suggesting the opening doesn't force one specific response.
Main Lines and Variations
From the position after 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6 6.e4 g6 7.Nf3 Bg7 8.Be2 0-0, the recognised continuations are:
Each branch leads to a different middlegame character — the resulting pawn structure decides what kind of game you get.
Common Mistakes
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Letting White own the centre — Hypermodern openings concede central space on purpose, but only if you strike back in time. Delay the counter-blow and you end up squeezed.
