This is my normal opening, @ alex_ratchkov - thanks for sharing this annotation with us in such detail.

with this development, white is enticed to attack the center further. This is going to be an exciting game!

white attacks the knight. this leaves black with the need to move on the next turn.

knight had this move or to e4. the other 2 forward moves would have been on the queens diagonal. Retreating back to the base line would have been an option also. This seems to be the best move by black.

Stahandske tried to resurrect the Alekhine defense on me. You can see the annotated game here. gameknot.com

I used to like playing 3.Nc3 (Nxc3 4.dxc3) in my OTB days. I tried 4.bxc3 once, but got axed.

This is the right move by black which is to attack and break up white's centre as quickly as possible.

I think Piece development is very important at this junction.

There was a time - about 40 years ago now (how time flits by!) in which the Four Pawns Attack (c4 with f4 to follow) was considered a near-on refutation of the Alekhine Defence. In my only Alekhine Defence game on GK (with the White pieces) I tried it but got no more than a draw.

white continues to develop and continues to increase control of the center.

black develops the second knight.

White's centre has given white a temporary plus in space. But it is hard to see how white can use this with any great effect so early in the game. However if white can retain a centre space plus toward the endgame then he may have chances to win.

I was looking at this move and considered Bc4 or Bc3 to develop and prepare to castle. I do see that this move is also a good defensive attack.

...g6 is an interesting idea though I think black is wishing upon a star if he can crack the white dark square juggernaut

would the line 7...exd6 be better black is going to deal with backward pawns or defend them?

It was a viable alternative, though with the black King still in the center opening up the e-file may prove dangerous for Black

This is already on a razors edge for black.

I daresay White dare not give the knight another bip by b4 on account of [A] (short term) the fork ...Nb3 and [B] (long term) the g7-bishop's lurking on the long dark diagonal.

Very astute observation, thank you for noting that  

It is wise to be aware of such tactics from your opponent but even wiser to see if it has any teeth to it.
