Bad name imho, it doesn't prevent Qxd4. 
is ok for white. 😎
Sicilian: 3...Nf6 ("Anti-Qxd4 Move Order")? Why?
Sort:
it prevents the version of qxd4 where white can still go c4 and get a maroczy bind. with a knight on c3 white's setup with qxd4 is not that critical.
i play it myself but not to avoid qxd4, rather to avoid the prins.

One of White's most common ideas in the Qxd4 line is to follow up with c4 before playing Nc3.
This move order is directed against that idea.

It disallows the Maroczy bind I believe
Interesting variation that derives from this move order though
white can be clever and try 2 d4 heading for the prins, so that after 2..cd 3 nf3 he takes and then f3 is possible, but there is 3..e5 here again preventing the prins.
the line where black sacrifices a pawn on post 6 is what i prepared. this is in principle white's best try to punish 3..nf6. but the problem is in practical play black has an easier time.
4 bd3 is a way to invite a maroczy bind, but i think this version allows black more possibilities.
besides 4 nc3, 4 dc, 4 bd3, white gets nowhere as far as my analysis goes.
also nice name "cortlever" although i don't know where it originates.
I'm relatively new to chess, so forgive me if there's something plainly obvious which I'm missing.
I was looking over some side-lines in the Sicilian on the analysis board, and I noticed that after 1.e4 c5 2.Nf3 d6 3.d4, Black has the move 3...Nf6, which Chess.com's opening book calls the "Anti-Qxd4 Move Order."
What is this move order supposed to prevent/avoid, and how does it avoid it? (I don't really understand how the move 3...Nf6 affects the move Qxd4 in the future, but again there might be something obvious that I'm missing.) According to the database this move order usually just ends up transposing into one of the other main variations of the Sicilian anyways (Najdorf, Dragon, Classical, etc.), so what advantages and/or disadvantages does this move order provide over the usual move order?
