Now you want to talk transpositions into the Alekhine's. Stop wasting my time. Post about the central pawn duo and Black attempting to destroy it.
I was talking about your asinine example of a rebuttal.

So, I've got a typo in my move sequence. You know what the right move is. You brought the example.
Stop splitting hairs. Black is challenging White to keep him from creating a central pawn duo. Period end of story.
@Zac_howland - I suppose you didn't bother visualizing his variation past move 1.
If you did, you'd see that
(1) 2.c4?? hangs the e4 pawn, so black can stop the "center duo" with 2...Nxe4, without the other garbage.
(2) 3...d5?? hangs a pawn, because the recapture
(3) 4...Nxd5?? hangs a piece, although it's nothing compared to
(4) 5.e4, which is an illegal move.
That typo is quite an important one, which he seems oblivious to...
