The idea

Black strikes at the centre immediately with ...d5 and lets White build an enormous pawn mass, planning to destroy it from the flanks.

Main line: 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.cxd5 Nxd5 5.e4 Nxc3 6.bxc3 Bg7

What White wants

  • Build the big centre with e4 and use the space
  • Defend the pawn mass and avoid trades that expose it
  • Play for a slow, grinding advantage or a kingside attack

What Black wants

  • Attack the centre with ...c5, ...Bg7 and ...Nc6
  • Trade pieces to expose the white pawns
  • Use the long diagonal and the queenside files for counterplay

Key idea

Understand this and the moves stop needing to be memorised.

An invitation to overextend

After ...Nxc3 and bxc3, White's centre is c3–d4–e4: the original c-pawn was exchanged on d5. The g7 bishop attacks d4, while ...c5 and ...Nc6 can add pressure. White's space is useful only if development and central activity keep pace.

Common mistake

Treating the pawn centre as either automatically strong or automatically doomed. Bc4, Ne2 and Be3 are standard development, not a demonstrated loss. White must calculate ...c5 exchanges and coordinate the pieces; Black must justify pressure with actual development.
