2. Classical London vs the ...Qb6 Counterattack

- 1...d5 – Black replies symmetrically with 1...d5, staking out central territory and preventing White's immediate 2.e4 advance.

- 2...c5 – Black counterattacks the center immediately with 2...c5, testing White's d4 pawn before piece development settles.

- 4.Nc3 – Dynamic development: White mobilizes the Knight to c3, threatening the annoying Nb5 jump with fork ideas on c7.
- 4...a6 – Necessary defensive prophylaxis: Black denies the b5 square to White's Knight to prevent dangerous c7 intrusions.
- 5.Rb1 – The Rook defends b2 while keeping the white Queen free to roam, preparing future central and queenside expansion.
- 5...Nf6 – Black develops the kingside Knight toward the center, contesting d5 and e4 while preparing kingside castling.
- 6.Nf3 – White develops the Knight to f3, controlling e5 and completing the harmonious mobilization of minor pieces.

- 7.exd4 – White recaptures with exd4, maintaining a rock-solid central presence and opening the diagonal for the light Bishop.
How to exploit the position
Contain Black's early Queen sortie without conceding Queenside weaknesses.
- Play Qb3 offering a favorable trade: if Black takes on b3, the a-file opens for White's Rook.
- If Black pushes ...c4, retreat the Queen to c2 maintaining control over e4 and e3.
- Complete development with Nd2 and Ngf3 before preparing the central liberation with e3-e4.
- Exploit the closed Queenside by breaking open the center with the thematic e4 strike.
