With 3...Nd4 you immediately put pressure on the bishop on b5. Instead of passively defending e5 or developing quietly, your knight jumps into an active central square where it attacks the bishop and cannot be kicked by 4...c6 (yet). This is the signature idea of the Max Lange Defense – you refuse to let White complete smooth development while dominating the centre. If White retreats the bishop (4.Ba4 or 4.Bc4), you can follow up with ideas like ...c6 and ...d5, gaining space. Even if White chooses the engine's best move – 4.Nf3 – you still stand perfectly equal. The statistics back up the strategy: from this position, Black wins practically the same percentage of games as White does.
White's Best Try: 4.Nf3 and How to Meet It
The most popular move in the database is 4.Nf3 (20,199 games), and it's also the engine's preferred continuation. After 4.Nf3, the best plan for you is 4...c6 (attacking the bishop again) followed by 5.Bc4 b5. This pushes the bishop back to a3 or forces it to trade off on b5, and you gain space on the queenside. White only scores 48.7% from here – well below average for a first-player result. The key is not to rush. Your ...b5 advance gives you a comfortable pawn majority on the queenside, and your knight on d4 remains annoyingly placed. As long as you don't let White chase it away with tempo, you'll reach a balanced middlegame where your active pieces make up for any space concessions.
Watch Out: The Inaccuracy 4.d3
The database identifies 4.d3 as a concrete mistake – it's listed as an inaccuracy that loses roughly 0.6 pawns of advantage compared to the engine's first choice 4.Nf3. Why? Because 4.d3 is too passive. It doesn't challenge your knight on d4, and it allows you to follow up with ...Nf6, ...Be7, and ...0-0 while White has wasted a tempo on a quiet pawn move. White's score after 4.d3 drops to just 47.5% across 6,986 games – the worst result among the top six replies. If your opponent plays 4.d3, you can be happy: you've already outplayed them in the opening. Just develop naturally, keep the knight on d4 for as long as it's useful, and enjoy the extra tempo.
Three Popular Replies and Your Simple Plans
Let's look at the other common White moves and how to respond as Black: - 4.Bc4 (17,972 games, White scores 49.9%): A natural retreat. Your plan: attack it immediately with 4...b5, gaining space and forcing it to move again. If 5.Bb3, then 5...Nxb3 is fine, or you can play 5...c6 and build a centre. - 4.Ba4 (9,321 games, White scores 49.9%): Similar idea – chase it with 4...b5 5.Bb3 (or Bc2) and then develop quickly with ...Nf6 and ...Bc5. - 4.Nge2 (3,941 games, White scores 47.7%): This is awkward – White blocks their own bishop. You can simply take on e2 after they recapture with king (preventing castling) or retreat the knight to b5. In any case, you're already equal or better. The common thread: whenever White avoids the critical 4.Nf3 line, your position is comfortable.
