After 4.e3 the position is yours to steer, but Black has the move. The engine's top recommendation for Black is Bd6, taking direct aim at your light-squared bishop and challenging the London setup immediately. In over 2.5 million games Black chose this move — making it by far the most popular response. Your job is to know what to do next, and the engine gives a clear plan: Ne5, putting immediate pressure on d7 and preparing to castle. This isn't just theory — understanding the Bd6 line will serve you in roughly a third of all games you reach this position.
What the Statistics Tell You
The numbers from a massive database of 7,559,062 games paint a clear picture. You win 52.0% of games from here, with only 4.3% ending in draws. That's a fantastic practical result for White — your position is solid and your winning chances are real even against tough opposition. But the key insight is in the contrast: when Black plays Nc6, your score jumps to 54.7%. When Black plays Bb4+ (checking your bishop), your score rises even higher to 57.8%. These are the moves where Black is already slightly misplacing a piece, and you should be ready to capitalise.
Responding to the Most Popular Replies
Here's how to handle what Black throws at you most often: - Bd6 (most popular, 2.5M games): Meet it with Ne5. The knight eyes several squares and prepares to castle. Black's score drops to 51.1% here. - c5 (1.9M games, White scores 50.1%): Black strikes at your centre. Your standard London setup is well placed to handle this — maintain the pawn chain and develop naturally. - Be7 (842k games, White scores 52.5%): A quieter, solid choice. You have nothing to fear — continue developing with moves like Nbd2, Bd3, and castling. - Nc6 (703k games, White scores 54.7%): Your best win rate against any popular reply. Black's knight may look active, but it can become a target after c3 and Bd3. - Bb4+ (280k games, White scores 57.8%): Your highest-scoring popular line. Interpose with c3, gaining a tempo. The bishop will have to retreat, and you get a free pawn move. - a6 (230k games, White scores 52.1%): A waiting move. Develop normally — your London setup already controls the key squares.
Common Mistakes to Avoid
Two errors crop up regularly in this position. The first is over-pressing — the London is not a sharp attacking system, and forcing a win too early often backfires. The second is failing to recognise when Black has misstepped. If Black plays Bb4+ or Nc6, you have clear ways to gain a small but lasting advantage. Keep your setup solid: develop your knight to d2 (not c3), fianchetto your queen's bishop early, and castle quickly. If Black plays Bd6, the engine's recommended Ne5 is your best friend — it prevents Black from exchanging bishops on your terms and keeps your structure intact.

Frequently asked questions
Is the London System good for beginners?
Yes — the London System is one of the best openings for newer players because it follows straightforward development principles regardless of Black's responses. After 1.d4 d5 2.Nf3 e6 3.Bf4 Nf6 4.e3, you already have a solid centre and good piece placement. You don't need to memorise long tactical lines; instead you focus on sound chess ideas like developing pieces and castling early.
How should White respond to Bd6 in the London System?
The engine's best move is Ne5, attacking the bishop and preparing to castle. This prevents Black from exchanging bishops on their terms and keeps your light-squared bishop active. From there a typical continuation is O-O followed by c3, reinforcing your centre and controlling d4. The statistics show White scores a solid 51.1% in this line.
What is the best way to handle Bb4+ in this London position?
Interpose with c3. This forces the bishop to retreat — it will likely go back to e7 or to d6 — and you gain a valuable tempo. White scores 57.8% when Black plays Bb4+, because Black's early bishop sortie loses time and you end up with a free pawn move in the centre. Develop naturally after that and you'll maintain your small edge.
How often does White win in the London System with e6 Nf6?
Across over 7.5 million games, White wins 52.0%, draws 4.3%, and Black wins 43.7%. That is a very strong practical result — your chances of outplaying your opponent are real, especially since the position is evaluated as dead level by the engine. The low draw rate (4.3%) means most games are decided by tactical and strategic play rather than early simplifications.
