The idea

Black plays ...c5 against 1.d4 and accepts a locked, asymmetric structure where the fight is over the d5 pawn and the dark squares.

Main line: 1.d4 Nf6 2.c4 c5 3.d5 e6 4.Nc3 exd5 5.cxd5 d6

What White wants

  • Protect the d5 pawn and use the extra central space
  • Build e4 and consider a supported e4–e5 break or kingside play
  • Pressure the backward d6 pawn when development permits

What Black wants

  • Seek ...b5 counterplay and pressure a later e4 pawn on the e-file
  • Play on the dark squares and the half-open e-file
  • Use the queenside pawn majority in the endgame

Key idea

Understand this and the moves stop needing to be memorised.

Central space versus queenside counterplay

The exchanges leave White's c-pawn on d5 and Black's e-pawn gone. White has central space; Black has a queenside pawn majority and a half-open e-file. Once White plays e4, ...Re8 can pressure that pawn, while ...b5 seeks active queenside play.

Common mistake

Ignoring queenside counterplay while making slow kingside moves. White's space does not prevent ...b5 or pressure on e4. Queen exchanges are not inherently bad: assess the d6 target, piece activity and pawn majorities rather than treating material or space as decisive.
