1.e4 Nc6

I am a chess player with affinity to tactical positions not shying away from sacrifices in order to obtain initiative or a promising attack. The Nimzo, however, regularly leads to positions I am uncomfortable with. Does anybody here have an idea for a sharp white response to add some spice to the game? For white of course, I would never touch this opening with the black pieces.

1. e4, Nc6 2. Nc3, and black has little choice but to go into a vienna with e5, or play Nf6, where 3. d4, d5 4. e5 leads to a bad french defense for black with a blocked c pawn, and 3... e5 4. dxe5, Nxe5 5. f4 and white gets the center and initiative. 3.. e6 is really black's best, but this just allows white to occupy the center so you should really be fine from there.

Nc3 isn't the best move I don't think to try and refute the nimzowich defence, but it is by far the simplest, and creates positions black will likely be uncomfortable with. Hope this helps.

I guess i'll make a diagram too

The problem is, Vienna is very comfortable for black, so still Nc6 could be good.

EDIT: Irrelevant post.

Thanks for your views. I am not so concerned with 2.e5 but the lines after 2.d5 3.Nc3. Too calm...

2. Nc3 can lead to sharp Vienna positions if Black plays 2...e5 e.g. 3. Bc4 Bc5 (better is 3...Nf6) 4. Qg4 Qf6  5. Nd5. 

2...e6 is another alternative for Black after 2. Nc3, trying to get into a surprisingly resilient French setup, despite ...Nc6, by following up with ...d5 and ...Bb4, but 3. a3 takes some of the fun out of this setup for Black.

I don't know that I'd go so far as to say 2...e5 is the most common reply after 2. d4 -- it's the Kevitz line, and allows a transposition right into the Scotch if White wants it: 3. Nf3.  I think after 2. d4 the main line for Black is 2...d5

I respond with 2. Nf3 and often transpose into an e4-e5 opening. If they go Nf6, just chase the knight with your central pawns, stockfish gives white a +1 advantage after 2. ...Nf6. If 2. ...d6, you can play d4 and enjoy your big white center, and if 2. ...d5 you can play exd5 and play a scandi that's already +1 for white.

the bad french thing is greatly exaggerated. players as strong as Andreikin and Timofeev have it in their repertoire, not to mention the fact, 3.bb4 instead of3.d5 is a legitimate sideline

another thing is ,while i find 2.nc3 harmless and try to avoid playing "boring" lines in the nimzowitsch. 2.e5 can easily keep things asymmetrical, now, if white plays it like a vienna gambit, exf4 is closer to kg territory than vienna as the king knight doesnt block qh4. if white plays 3.g3, black can play 3...bc5, 4...a6 , 5.d6 and 6. nge7, this option to not block the f-pawn is likely superior to nf6 in the g3 vienna and close to equal. If white plays 3.nf3, you can always play for an early g6 system or my own concoction d6 4.d4 bd7!?
