The Nimzo-Indian Defense: e4 — Black's Bold Counterstrike
When you face 1.d4 as Black, the Nimzo-Indian is one of your most reliable ways to fight for the win. But White has a tricky, aggressive sideline: instead of the normal 4.e3, they push 4.e4, attacking your knight and daring you to take the pawn. The Nimzo-Indian Defense: e4 (ECO E20) leads to a sharp, concrete position after 4...Nxe4, where Black has already grabbed a pawn and must navigate White's threats. The engine rates this a clear -0.87, meaning you are clearly better here. But one wrong move can ruin everything — the drill below will train you to find the right answers and punish White's most common inaccuracy.

This isn't just a gambit — you have genuinely won a pawn, but at the cost of leaving your knight exposed in the centre. White has several ways to attack it, and the key is not to panic. Your bishop on b4 pins the knight on c3, making it awkward for White to recapture immediately. Statistically, Black wins an impressive 55.8% of games from this exact position (with only 3.0% draws and 41.2% White wins), confirming that your practical chances are excellent. The main battle revolves around whether White can generate enough activity to justify the missing pawn, or whether your extra material will tell in the middlegame. The engine's verdict of -0.87, a clear edge for Black, should give you confidence: you are not just surviving — you are playing for a win.
The Engine's Top Choice for White — And How to Answer
White's best move is Qc2, and it scores a respectable 49.1% for White across 9,597 games. After 5.Qc2, you should play 5...Nxc3, forcing White to recapture with the b-pawn (6.bxc3). Then White continues with 6...Bd6, retreating the bishop to a strong diagonal. This is the engine's recommended line. Notice that by 6...Bd6 you have consolidated: the knight is gone, you are up a pawn, and White's doubled c-pawns are a long-term weakness. If you face this line in the drill, stay calm, take the sequence step by step, and trust that the position rewards Black's solid play.
The Most Common Mistake: Bd2
The most popular move in the database is 5.Bd2 (played over 14,900 times), but the engine flags it as a clear inaccuracy, costing White about 0.6 pawns of advantage. The better move was Qc2. Why is Bd2 a mistake? It develops the bishop but does nothing to challenge your well-placed knight on e4 — White cannot exploit any pin immediately, and you can consolidate your extra pawn while maintaining your structural advantage. The stats back this up: White scores only 41.7% after 5.Bd2, compared to 49.1% after the correct Qc2. If your opponent plays this, you should be happy — it's one of the easiest ways to cash in your advantage. The drill will let you practise recognising and punishing this error.
Other Lines You Should Know
White has several alternative tries, and knowing their scoring percentages gives you an edge at the board: - 5.Ne2 (4,073 games, White scores 42.2%) — a quiet move that develops but doesn't pressure your knight. Simply retreat or exchange. - 5.Qd3 (3,437 games, White scores 39.5%) — White threatens the knight but leaves the queen exposed. This is one of White's worst scorers. - 5.Qb3 (2,099 games, White scores 44.0%) — attacks the bishop on b4 and the knight simultaneously; be precise in your response. - 5.a3 (1,843 games, White scores only 30.9%) — this is White's absolute worst option, losing you almost nothing — a quick check of the database or a bit of calculation will show you why. In every case, your plan is the same: keep your extra pawn, don't overextend, and remember that you are the one playing for a win.

Frequently asked questions
Is 4...Nxe4 a safe move in the Nimzo-Indian?
Yes, it is fully sound. The engine gives -0.87, a clear advantage for Black, and Black wins 55.8% of games from this position. You win a pawn and White must prove compensation. The main risk is if you don't know how to react to White's best reply (5.Qc2) — but with a little practice it's very playable.
What is the best response to 5.Qc2 in the Nimzo e4 line?
The engine's best continuation is 5...Nxc3 6.bxc3 Bd6. You exchange the knight, force White to double your opponent's c-pawns, and retreat the bishop to a great square. You keep your extra pawn while White's structure is damaged.

What is White's worst option after 4...Nxe4?
The move 5.a3 is White's worst-scoring option, with a paltry 30.9% win rate for White across 1,843 games. It's a waste of a tempo that doesn't challenge your knight — you should be able to consolidate your extra pawn without trouble.
