Learn How to Win Space: London System Pressure
This puzzle comes from the London System and shows how a small opening edge can turn into a decisive advantage when the center is challenged at the right moment. White has more space and better piece activity, but Black can use a forcing pawn break to open lines and punish the bishop placement. The key idea is not a flashy mate, but a strong tactical sequence that gains time, improves piece coordination, and creates a lasting positional plus in the middlegame.
