Nimzowitsch defense?

I have been playing around with this defense for a week now, I can’t find anything on it.

i have mostly been practicing a preparing a move list against the most common moves, and giving them names.

anyone have a good resource?

scroll down to the bulleted list. Let me know if that's what you wanted!

Or are you looking for a resource/book like "Play 1...Nc6", which was published by Everyman about a decade ago?

Both suggestions are great.

"the dark knight system" is best, although "play 1.nc6" is satisfactory for some lines  (and terrible at others)

You have to be prepared for e4 Nc6 Nf3!  

Here is game of the Nimzowitsch defense:

It really depends on how you want to play it. The Dark Knight is with ...e7-e5, Play 1...Nc6 is with ...d7-d5. They're completely independent repertoires.

In this case, listen to him.  I only mentioned Play 1...Nc6 as that is the only one I own and know that it is at least somewhat decent, but not going to say it is best having not seen the others, like The Dark Knight System.  Otherwise, all books that I have that cover it are repertoires for White AGAINST it, like Beating Unusual Chess Defenses: 1.e4.  I do not play this at all with Black, so take his advice over mine.

If you ever need help in the French or Kings Indian Defense - come find me.  The others I leave to the specialists of those openings.

play 1.nc6 is satisfactory on how to play 1.e4 nc6 2.d4 d5, and not a bad chigorin supplement agaisnt 1.d4 (although he chickens out of 1.d4 nc6 unlike the dark knight system) but the problem with the book is 

1. it chickens out, and recommends the nc6 french deviation, even when black can afford being more brave. 1.e4 nc6 2.d4 d5 3.nc3  e6 is fine but meek, more testing for white is dxe5 d5 nb8! where c6 is comming and black has nearly equalized already. 

2. more importantly , black recommends something called el columpio 1.e4 nc6 2.nf3 nf6?! which leads to some positionally horrendous positions without even that much effort from the white side. 

3.a minor complain but one reason why the book chickening out on 1.d4 nc6 is relevant is because the positions after 1.d4 nc6 2.c4 e5!? (which can arise via 1.c4 nc6 d4 but rarer this way)are often superior to 1.e4 nc6 2.d4 e5, but you will rarely see that if you follow the book's suggestions, despite the fact this book focuses on the knight tango approach.

Seems like the e5 Nimzowitsch isn’t as popular as the d5 but I love it.  The line I play against it is dxe5 Nxe5 f4.  Here’s a gif of a game I played on lichess in the most common line I see.  Zero mistakes/blunders.  It’s such an easy plan to follow.  

i prefer the d5 nimzo to the e5 nimzo, but i get virtually the same position as this from both 1.nc3 d5 2.e4 d4 and 1.d4 nc6 2.c4 e5 all the time, and its almost always a very easy straightforward win. Positionally the other side is as lost as you can be without the eval showing it.
