The Modern Benoni Defense arises after 1.d4 Nf6 2.c4 c5 3.d5 e6 and falls under ECO code A60. Popularized by Mikhail Tal in the 1950s and embraced by counterattacking specialists throughout the 1980s and 1990s, the Modern Benoni sees Black accept a structural weakness on d6 in exchange for dynamic compensation that surpasses what the King's Indian typically offers. The key advantage is that the long diagonal is opened for the dark-squared bishop, and Black obtains a mobile queenside pawn majority that, supported by a bishop on g7 and a knight frequently anchored on e5, can generate a dangerous queenside advance capable of queening a pawn if White is not vigilant. The modern main line continues with 4. Nc3 exd5 5. cxd5 d6 6. Nf3 g6 7. h3, where White pursues a restrictive strategy, developing classically to secure a modest but stable space edge while limiting Black's kingside activity. Black can exploit the tempo spent on h3 by launching immediate operations on the queenside. The Fianchetto Variation with 7.g3 offers White a simpler, positional alternative. The older main line, 7. e4 Bg7 8. Be2 O-O 9. O-O, sees White develop ambitiously and target the d6 weakness through maneuvers like Nf3-d2-c4 and Bc1-f4, while Black can counter with plans involving ...a6 and ...b5, ...Re8 to pressure e4, or the ...Nb8-d7-e5 regrouping combined with ...g5 to cement control of e5. White also has aggressive options involving early f-pawn advances and a rapid e4-e5 break, which can be devastating against slow development; Black can neutralize these by choosing the move order 1.d4 Nf6 2.c4 e6 3.Nf3 c5, blocking the f-pawn in advance. With 2.6 million Lichess games across all rating levels, it is a well-established opening choice.
