Najdorf against Maróczy bind

I mean this variation sorry for mistake 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Bd3

You don't always get to play the variation you want. After 5. Bd3, you have to accept that you won't be playing a Najdorf. The positive side is that White's B is badly placed on d3. Its influence is limited to defending the e-pawn, and it reduces White's pressure on the d file.

5...Nc6 is an excellent move: it develops a piece and challenges White's N on d4. Notice that White can't play 6. c4 or 6. Nc3, because you can then play 6...Nxd4. If he retreats the N, you have easy development and a solid position. If he plays 6. Nxc6, you recapture with the b-pawn, strengthening your center.

Long story short, you basically cannot play the Najdorf. You have to react to their moves and not just play like a robot.

A far more common example of this is the Prins Variation. After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6, White is under no obligation to play 5.Nc3, after which 5...a6 would be the Najdorf. The Prins Variation is 5.f3! This basically gives Black 3 options, and the Najdorf ain't one of them.

After 5...a6?, White will play 6.c4! and the move ...a6 is a waste of time. Black instead has the following options as everything else is bad:

A) 5...e5, which after 6.Nb3, you can play 6...Be6, or go for the endgame after 6...d5.

B) 5...Nc6, and then either 6...Qb6 or an early ...g6 with a direct transposition to the Accelerated Dragon

C) 5...e6, often leading to a Hedgehog position.

Playing 5...a6 "automatically" would be like me playing ...c5 automatically in the French.

After 1.e4 e6 2.d4 d5 3.Nd2 or 1.e4 e6 2.d4 d5 3.e5, the move 3...c5 is Black's strongest.

But after 1.e4 e6 2.d4 d5 3.exd5 exd5 4.Nf3, 4...c5 is very risky, and after 1.e4 e6 2.d4 d5 3.Nc3, the move 3...c5 is borderline losing!

The fact that you are trying to cookie cut the Najdorf when the Najdorf isn't possible tells me that you remembered lines and don't understand the ideas one iota, as otherwise, you would be able to understand why 5.Bd3 isn't best. Similar to how I once faced over the board 1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Qb6 and he played 5.Ne2 instead of 5.Nf3. It didn't take me long to figure out the problem. If he advances f2-f4 to protect e5, then the diagonal to his king once he castles is weak and Black has tactics on the d4-pawn. If he doesn't advance the f-pawn, then the e5-pawn is underprotected and weak. However, that means a shift from the norm. The norm is to attack the d-pawn at the base of the pawn chain after the trade on d4. However, in this case, Black must switch course and go after the weak e5-pawn and not the traditional d4-pawn.

So long story short, you need to get your mind off the Najdorf when the Najdorf isn't possible, and figure out the right moves for the given situation.

I think I agree with @OldPatzerMike

With the c6 pawn controlling d5 and the semi-open b-file this looks significantly better for Black than the deal he gets in the Accelerated Dragon.
