12.1 Fix, Attack, Win

A weak pawn is a pawn that cannot be protected by other pawns: isolated, backward or doubled. The plan against it has three steps: fix it so it cannot advance, attack it with more pieces than can defend it, and win it or force the defender into passivity.

Diagram 12.1Black to move

Example 12.1 · The doubled c-pawns

The Nimzo-Indian, Sämisch Variation. White has the bishop pair; Black has damaged White's queenside pawns.

Black closes the centre, castles, and then attacks the c4-pawn with ...♘a5, later ...♗a6 or ...♗c8–a6 and ...♖c8. The doubled pawn on c4 cannot be defended by another pawn, so it becomes a permanent target.

12.2 The Principle of Two Weaknesses

One weakness can often be defended. The winning method is to attack a weakness until the defender's pieces are tied to it, then open a second front on the other side of the board. The defender cannot hold both at once.

TipDo not hurry when you have a lasting advantage. Improve your pieces, fix the weaknesses, and only then open the second front. Strategic advantages do not disappear; tactical chances do.

Remember

  1. Weak pawns: isolated, backward, doubled.
  2. Fix the weakness, attack it, then win it.
  3. One weakness can be defended; two weaknesses usually cannot.
  4. Don't hurry: strategic advantages last.
