Lessons

What you'll learn

Target Backward Pawns

Black's backward g-pawn becomes a long-term target, and White uses the square in front of it to increase pressure.

Understand the London Plan

The London System is more than an opening setup: its piece placement and pawn structure create plans that carry into the middlegame.

Use Open Files for Rook Activity

White's control of the a-file shows how active rooks and penetration behind the pawns can turn positional pressure into concrete threats.

Key positions

The moments that decided it

Move 43 — Ng6

43. Ng6 — the knight strikes

White's queen had already dug in on c7, and now the knight leaps into g6. It isn't even the engine's top choice — Nf5 was stronger — but Ng6 is devastating anyway. The knight tears into the king's shelter around the backward g-pawn and leaves Black in a decisively lost position. Black tries Rg8, pulling the rook back to defend, but White follows with Qf7, tightening the net around the exposed king. This is the payoff of the pressure that came before it — the open file, the weakened kingside and the queen's infiltration all converging into one attack.
