Crushing Black's Nimzowitsch Defense: Declined Variation Nf6
After 1.e4 Nc6 2.Nf3 Nf6, you can seize space immediately with 3.e5, kicking the knight and taking control. This is the Nimzowitsch Defense: Declined Variation with Nf6, and the engine rates it +1.10 — a clear advantage for White. That means you are clearly better from the start. Black has brought out two knights before developing their pawns, and your e4-e5 push asks them to decide where to run. The resulting position is highly pleasant for you: across over 282,000 games, White scores a commanding 55.8% (with only 3.5% draws). Below the interactive drill, you'll learn which Black retreats to welcome and which to punish.

Create a free account →The Big Idea: Space and a Target
The move 3.e5 does two things at once. First, it gains space in the centre — your pawn chases a knight while also clearing the way for your dark-squared bishop and queen. Second, it creates an immediate tactical threat: Black's knight on f6 is attacked and must move. In the Nimzowitsch Defense, Black often tries to provoke pawn advances and then undermine them. Here, you have advanced safely because neither Black knight can effectively attack e5 yet — the knight on c6 is too far away, and the one on f6 is being chased. Your goal is simple: develop quickly, keep your pawn on e5 as a strong outpost, and punish any greedy knight move that tries to win it back too early.
Black's Best Try: Ng8 and the Main Line
The engine's top recommendation for Black is 3...Ng8 — yes, back to the starting square! This humble retreat avoids material loss and prepares to challenge your centre with ...d6. After 3...Ng8 4.d4 d6 5.Bb5, White has an ideal setup: a massive pawn duo on d4 and e5, the light-squared bishop pinning the knight on c6, and free development for all remaining pieces. Black has wasted two full moves (Nf6 and Ng8) and still needs to untangle. While this is Black's best try according to Stockfish, you already enjoy a +1.10 advantage — just develop naturally and Black will struggle to find counterplay.
Punishing the Popular Blunders
Most club players won't retreat to g8. Instead, they'll try to keep their knight active — and that's where you strike. Here are the three most instructive mistakes from the database: - 3...Nxe5 (6,546 games, White scores 74.4%): Taking the pawn is a mistake that costs Black about 2.2 pawns. You simply recapture 4.Nxe5 and Black has no good way to recover the lost material while your development is far ahead. - 3...Ne4 (25,800 games, White scores 63.6%): A mistake worth about 1.2 pawns. This odd jump blocks your e-pawn but can be met by 4.d4 (threatening Bd3 or Qe2), after which Black's knight on e4 is a target rather than a threat. - 3...Ng4 (83,913 games, White scores 53.1%): The most common bad move. It's an inaccuracy costing about half a pawn — better was Nd5. You can continue 4.d4, threatening h3 to trap the knight, or simply develop with Bc4 or Be2, maintaining your space advantage.
Why Nd5 Is Black's Best Practical Chance
The most played move by far is 3...Nd5 (139,800 games), and it's the one you should prepare for. Black retreats the knight to the relatively solid d5 square, eyeing your e-pawn and keeping options open. Even so, White scores 53.9% from here — a solid plus. Your plan: continue 4.d4, supporting the e5 pawn and opening lines for your bishops. Black may try ...d6 or ...e6 next, but you can develop naturally with c4 (kicking the knight again), Bc4, or Nc3. The knight on d5 looks active, but it's unstable — any pawn push by you (c4, d5) can chase it away with gain of time. Keep your centre intact, and your space advantage will translate into attacking chances.

Frequently asked questions
Is 3.e5 in the Nimzowitsch Defense a good move for White?
Yes, it's excellent. Stockfish evaluates the position at **+1.10** — a clear advantage for White. The move gains space, attacks Black's knight, and forces a decision. Across over 282,000 games, White wins 55.8% of the time from this position.
What happens if Black plays 3...Nxe5 in the Nimzowitsch Defense?
That is a mistake worth about 2.2 pawns. Black takes your e5 pawn, but you simply recapture 4.Nxe5. Black has no good follow-up to regain the material, and your development comes for free. White scores an enormous 74.4% after this blunder.
What is Black's best move after 1.e4 Nc6 2.Nf3 Nf6 3.e5?
The engine recommends 3...Ng8, retreating the knight all the way back. After 4.d4 d6 5.Bb5, White has a huge space advantage and Black has wasted two moves. While White is still clearly better (+1.10), this line avoids the quick disasters seen after moves like Ne4 or Nxe5.
How should White punish 3...Ng4 in this line?
3...Ng4 is an inaccuracy (costs Black about half a pawn; better was Nd5). White can play 4.d4, threatening to trap the knight with h3. Even if Black avoids immediate loss, White's centre and development are far superior. White scores 53.1% against this move in practice.
