Key ideas

  • The exchange creates the Carlsbad structure: White's pawns on d4 and e3 face Black's on d5 and c6, White has the half-open c-file and Black the half-open e-file. Black's c8 bishop is no longer shut in, so the game is decided by plans rather than by the opening moves.
  • After 5.Bg5 c6 6.e3 Be7 7.Bd3, White decides where the king's knight and the king go. With Nf3 and short castling, the minority attack (Rb1, b4 and b5) is the standard plan, aiming to leave Black with a weak pawn on c6 or an isolated pawn on d5.
  • With Nge2, f3 and e4, a plan associated with Botvinnik, White uses the central majority instead. The knight on e2 keeps the f-pawn free, and White can castle on either side.
  • The Reshevsky Variation, 5.Bg5 c6 6.Qc2, keeps both plans open and stops ...Bf5, which would otherwise trade off White's good light-squared bishop.

Plans for White

Develop with Bg5, e3, Bd3 and Qc2 so that Black's bishop cannot come to f5 for free. Then choose: Nf3, short castling and b4-b5, or Nge2, f3 and e4 to make the central majority count.

Plans for Black

Look to exchange the light-squared bishops with ...Bf5 or ...Bg4, and reroute the queen's knight through d7 and f8 to g6 or e6, where it helps defend the king. Use the e-file and ...Ne4 for activity, and against b4-b5 decide in good time whether to accept a weak c-pawn or to answer with ...c5 and hanging pawns.
