Openings Guide / 1.d4 — Closed and Semi-Closed Games
1.d4 d5 2.Nf3 Nf6 3.Bf4
The London System is one of the most popular openings at club level and increasingly at the grandmaster level. White develops the bishop to f4 early, building a solid, reliable setup before committing to a pawn structure. Magnus Carlsen has used it regularly as White, calling it a key part of his repertoire.
The London System is built on solidity and flexibility. White typically plays d4, Nf3, Bf4, e3, Bd3, c3, and castles short — a setup that is almost impossible to attack directly. It's an excellent choice for players who want a reliable, low-maintenance opening.
