Nimzowitsch Defense
Quick reference
1...Nc6 develops a piece against 1.e4 without touching a pawn at all — a genuinely unusual first move for Black, though a natural one for the player it's named after. Aron Nimzowitsch built much of his hypermodern philosophy around exactly this kind of move: let White build a pawn center, then attack it with pieces rather than racing to occupy the same squares with pawns of your own.
Sound, just uncommon
This isn't a dubious line the way a genuine gambit is. Nc6 doesn't lose material, doesn't create an immediate weakness, and doesn't commit Black to anything that can be punished by force. It's simply less efficient than the well-trodden alternatives: it blocks Black's own c-pawn from later supporting a ...d5 or ...c5 break, which is a real long-term cost even though nothing goes wrong in the short term. Most players who want a hypermodern approach against 1.e4 find Alekhine's Defense or the Modern Defense achieve the same goal without that structural downside.
The central strike that follows
The most common and most testing continuation is 2.d4 d5, where Black finally stakes a claim in the center now that the knight is already developed and can support the tension that follows. After 3.e5, White grabs space and gains a tempo attacking nothing yet, but Black gets the thematic ...Bf5 in before playing ...e6 — developing the light-squared bishop outside the pawn chain, which is exactly the structural problem French Defense players spend a lot of effort trying to solve.
Resist the urge to refute it
There's no forced punishment for 1...Nc6 waiting to be found, so don't spend moves hunting for one. A big, calm center — 2.d4, followed by natural development — is enough on its own, since the position is genuinely playable for Black and rewards a normal space-and-development edge rather than a knockout blow.
For a more established, more heavily analyzed way to meet 1.e4 without mirroring it, see the Caro-Kann Defense, which solves the light-squared bishop problem this defense also tries to sidestep.

Frequently Asked Questions
Why does the knight on c6 block Black's own plans?
A common follow-up in many 1.e4 defenses is a later ...c5, striking at White's center from the side. With the knight already committed to c6, that pawn break isn't available, which narrows Black's options in the middlegame even though nothing is immediately wrong with the position.
Is this the same defense Bobby Fischer once tried?
Fischer experimented with 1...Nc6 on rare occasions, which is part of why the line has more name recognition than its actual usage rate would suggest — but it never became part of his regular repertoire, and it hasn't become a mainstream choice for any elite player since.
What if White avoids 2.d4 and plays something quieter?
Against 2.Nf3 or 2.Nc3, Black usually continues with a normal developing setup — ...e5, ...d6, or ...g6 depending on preference — since the whole point of delaying the center with Nc6 was to see what White commits to first before deciding how to respond.
