how do you like this line in the center counter defence

honestly.  i dont think this is a hopeful line because 2. e5 changes everything.  but if you like playing that style then go for it.  but me personally, i would just push the pawn.

In the move order posted, this should just about never happen.

 

However, the position is adequate for Black, and there's a different move order to get to the same point that a lot of players will play into - so get to that position that way (see below):

 

1. e4 d5 2. exd5 Nf6 3. Nc3 Nxd5 4. Nxd5 Qxd5. 

 

Same result, much more reliable and sensible move order. 

But in that line white rarely plays Nc3.

As previously stated, you are going to end up in an Alekhine more often than not.  Are you prepared for 1. e4 Nf6 2. e5...?
