user1105: After white plays 1. d4, is it still possible for black to play the Najdorf Defense?
Is it possible, for Black to play in a way in order to reach a Najdorf setup? If so, how should Black continue?

user2001: You can try
[FEN ""]
1.d4 c5 2.e4 cxd4 3.Nf3 d6 4.Nxd4 Nf6 5.Nc3 a6

In general, it is not easy to transpose to an "e4" opening when white begins with d2-d4. It is easy for white to avoid the Sicilian system in the example shown above, e.g. with 2.d5 instead of 2.e4. Having said this, some players choose 1.d4 just for fun and would actually prefer to transpose to an "e4" opening if the chance is given. For instance, they would choose 2.e4 in this situation
[FEN ""]
1.d4 e6 2.e4 d5

Thus transposing into the French system. Perhaps because they are scared of the other systems they might face, e.g. 2.c4 f5. So against a player who is not comfortable with the d4-systems, it makes a lot of sense to transpose to your favorite e4-system. Happy hunting!

user924: If the following five moves by both sides happen in a game, then you have the position that's called the Najdorf Defence:
[FEN ""]

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6

However, white is by no means forced to play those moves. He can also play, say, 2.d4, 2.f4, 2.c3, 3.Bb5+, or 4.Qxd4, or 5.f3, or a lot of other moves.
So black can't always get a Najdorf after 1.e4.

user307: If White starts with 1.d4 it is possible to reach a Najdorf position, for example:
[FEN ""]
1.d4 d6 2.e4 c5 3.Nf3 cxd4 4. Nxd4 Nf6 5. Nc3 a6

However, White has other moves on move 2, which still give them an advantage: 2. c4 and 2.Nf3, also White could play 3. c3. So Najdorf is not that easy to get. Moreover, some people play 1.d4 to avoid Sicilian and especially Najdorf; they will certainly not follow the above line.
