Is there a medium tough question here, @Coney?

To me White seems to be doing good in this position. How about 12. Bb5+ Nd7 13. Qe2 (or Qg2) intending f4? Or simply 12. h4

Black can just play 2... e5 and be happy that he managed to avoid the king's gambit, danish gambit, among others. You need to try 2. d4 if you really want to punish blacks opening and prove that 1...Nc6 is not that great of a move.

Nimzovich Defence is a viable opening. If you play 2.d4 you need to be prepared for the specialist lines, which is why I normally go with 2.Nf3 and Black has nothing better than 2...e5 leading to a normal King Pawn game. 

Can someone explain these lines to me better? thanks.

How about 2.f4? It goes into a KG type structure which is what 1...Nc6 players like to avoid.

Leads to an intersting game. Or,

with an easy game for Black, who is at least equal

Your top game is dumb. White would not play 3.fxe5 due to Qh4+.

missed that

After 2.Nf3 Black  can play Nf6 and play "El columpio" : 3.e5 Ng4 4.d4 d6 5.h3 Nh6

or "Colorado Defense" : 2. .. f5

??????

Black just plays 2. ..  d5  after 2.d4,  so what ?

Main lines are

3.e5 f6 4.f4 Nh6 5.Nf3 Bf5

3.exd5 Qxd5 4.Nf3 Bg4 5.Be2 0-0-0

3.Nc3 e6 4.Nf3 Nf6 5.e5 Ne4 6.Bd3 f5

I would rather do this than all the other complications.

Just transposes into the Scotch or Ruy Lopez; might as well play 1) ... e5 right away

I think too many players see a opening move like ...Nc6, and since it is not played as often think "there must be an agressive way to punish this." Sometimes, just regular developing moves are called for in order to "punish" an opening. For most openings such as this, play what you feel comfortable with. So if you want to play the Ruy, Italian, or Scotch, play 2.Nf3. If you are comfortable with 2.d4, then play it!

You played Bf5  played much to early :

3.e5 f6 4.f4 Nh6 5.Nf3 Bf5

Buy a good book on 1. .. Nc6 and study it, instead of publicating lines a real Nc6 player will never play.
