10.1 The London as Black
If you studied the London System course, you know White's ideas. As Black, the most effective answer is an early ...c5 with ...♘c6 and often ...♕b6, attacking b2 and d4 — the London's sensitive points.
Example 10.1 · ...c5 and ...♕b6
White plays a London setup with ♘f3, ♗f4, e3 and c3.
4...♕b6 attacks b2. After 5.♕b3 Black can play ...c4, gaining space on the queenside and forcing White's queen to decide. Black is comfortable.
Example 10.2 · A full London setup
Black challenges the bishop on f4 with ...♗d6.
Black develops naturally and prepares ...e5. The position is balanced and full of play.
10.2 The Colle
Example 10.3 · Against the Colle
White builds the Colle–Zukertort setup with b3 and ♗b2.
Black develops with ...♗d6, castling and ...b6, ready to meet White's e4 break. Against quiet systems, put your pieces on active squares and strike in the centre with ...c5.
Remember
- Against the London: ...c5, ...♘c6 and ...♕b6.
- b2 and d4 are the London's weak points.
- Against the Colle: ...c5, ...♗d6, castle, ...b6.
- Strike in the centre early.
