Blackmar-Diemer Gambit: Nf6 — Seize Your Advantage as White
The Blackmar-Diemer Gambit has a reputation for sharp, uncompromising chess — and the Nf6 line is no exception. After advancing 1.d4 d5 2.e4 Nf6 3.e5, you've pushed Black out of the centre and created immediate tension. The engine gives you a clear advantage, and the statistics back that up: White scores an impressive 56.9% across hundreds of thousands of games, with only 3.2% ending in draws. This page breaks down how to handle Black's best and most common replies, what to look for, and which moves punish your opponent most effectively. The interactive drill below lets you test your instincts against a real opponent.

The move 3.e5 is the heart of this variation. You've sacrificed a pawn (the one on e4) to gain space and restrict Black's knights — the Nf6 in particular now has nowhere comfortable to go. The engine rates your position at +1.01, a clear and lasting advantage for White. That means you are clearly better here from the outset, provided you follow up correctly. Black's knight must move again, and every option comes with a downside. Your task is to exploit the time Black spends retreating to build a powerful attacking formation.
Black's Best Reply: Nfd7
The engine's top choice for Black is Nfd7, which has been played 176,856 times — far more than any other move. With Nfd7, Black prepares to challenge your centre with ...c5 or support a future ...e6 advance. However, White still scores 53.9% in this line, and the engine's suggested continuation runs Nfd7 b4 a5 b5. Your b2-b4 advance gains queenside space and discourages ...c5, keeping your pawn chain intact. This position rewards patience: develop your pieces, maintain the central clamp, and look for opportunities to launch an attack on the kingside.
The Most Common Mistakes by Black
Three moves Black can play here are rated as errors by the engine, and knowing how to punish each one will win you many games. Ne4 is a mistake (losing about 2.0 pawns) and your opponent will try it 124,128 times — likely hoping you blunder the e5 pawn. Instead of taking, keep the pressure on and trust your advantage. Ng4 is an inaccuracy (losing about 0.7 pawns), appearing in 16,481 games. The knight looks aggressive but is misplaced and can be chased away. Bg4 is also a mistake (losing about 1.9 pawns), pinning your knight but at the cost of valuable time. Against all three, White's winning percentages are strong — over 58% in each case — so stay alert and don't let Black off the hook.
Turning Your Advantage Into a Full Point
While White's overall score is 56.9%, that number rises noticeably against Black's weaker replies. Against Bg4 you score 69.4%; against Nc6 you score 67.5%. The key is recognising that Black's position is already difficult after 3.e5 — they're fighting for equality while you are fighting for a win. Develop naturally: bring your kingside bishop to d3 or c4, castle quickly, and consider moves like f4 or c3 to reinforce your centre. The low draw rate (3.2%) tells you this opening leads to decisive, unbalanced games — exactly what you want when playing for a win with White.
