7.1 Hitting c7

With the pawn on d5 and the bishop going to g7, Black's c7-pawn is defended only by the queen. If White's knight comes to b5, it attacks c7, and the bishop on f4 adds to the pressure.

Diagram 7.1Black to move

Example 7.1 · 3.♘c3 and 4.♘b5

White's knight attacks c7. Black has to react at once.

Black usually defends with 4...♘a6. After 5.e3 c6 the knight goes back to c3 — it has done its job by forcing the black knight to the edge. Now ♗xa6 damages Black's queenside pawns. It is a small advantage, but a very concrete one, and Black has to know this line well.

TipA knight on a6 is far from the centre. If you can exchange it with ♗xa6 and leave Black with doubled a-pawns, you win a lasting structural advantage.

Remember

  1. Against ...g6 and ...d5, ♘c3 and ♘b5 attack c7.
  2. After ...♘a6, the knight can return to c3 when Black plays ...c6.
  3. ♗xa6 gives Black doubled a-pawns.
