The Classical Variation of the Benoni is reached with 6.Nc3 g6 7.e4, where White builds a full center with pawns on d5 and e4 and a knight on f3. White wants a later e5 break or queenside control with a4; Black wants ...Bg7, castling, and play with ...a6 and ...b5 or pressure on e4.

Key ideas for both sides

White

  • Develop with Be2 and O-O, then play a4 to stop ...b5, as all three engine lines do.
  • Reroute the f3 knight with Nd2 toward c4, where it hits d6 and supports e5.
  • Use Bf4 to pressure d6, and prepare the e5 break when Black's pieces are passive.

Black

  • Play 7...Bg7 and castle, then ...Re8 to hit e4 and slow White's e5 break.
  • Use ...a6 and ...Bg4 to trade the light bishop, as the second engine line does, easing Black's space problems.
  • Reroute the b8 knight with ...Na6 and ...Nc7, supporting ...b5 from the queenside.

Plans and pawn structure

The structure is the standard Benoni: White has a central majority with d5 and e4, Black a queenside majority with c5 and the half-open e-file. White plays Be2, O-O, Nd2 and a4, then aims for f4 and e5 or a knight on c4. Black castles, puts a rook on e8, and tries ...a6 and ...b5 or ...Bg4 to swap pieces. The side whose pawn break comes first usually gets the better game.

Where the engine's main line heads: Benoni structure: White pawn on d5, Black pawns c5 and d6. White has a pawn on d5; Black has c5 and d6 and no e-pawn. White has more space, Black has a queenside majority and an open e-file.

How to play against it

Play 7...Bg7 and castle before anything else. Then decide between ...Na6-c7 with ...b5 and ...Bg4 to trade the light bishop. Avoid slow setups that let White play e5 with pieces ready, since the d6 pawn and the f6 knight would suffer.
