The Milner-Barry Gambit, and the trap

The Milner-Barry Gambit is a variation in the french defence:

Now, it seems like white blundered his pawn. But really, white has set up a trap.

However, if you come up to a experienced player of the gambit, he/she would probably play this:

Bd7 is actually a mistake by black which many French players commit as dxc5 Bxc5 O-O gives white a small edge. Black should play cxd4 cxd4 and then Bd7 which leads to the Milner Barry gambit proper. The modern method lately has been to 0-0 and Nxd4 Nbd2!? which leads to interesting games.

I don't understand. Doesn't 7. dxc5 Bxc5 8. O-O give Black a small edge?

No chesster, as WHITE CONTROLS THE CENTER, and that makes up for the lack of a central pawn. White has a nice outpost on his knight on d4. 

Does White really control the center? I don't understand how the e5 pawn constitutes a center.

The d4-square also isn't worth a lot when it's attacked by three pieces, and the only piece that benefits from it is the guardian of the weak e5-pawn. Sure, White "controls the center", but he "controls the center" in the entire Advance French... for a while.

So? That's a well-known line. I have a valid question about this and all I get are 1100-level answers.

...

u play dxc5 so u can vacate d4 to put a piece on it later

when black plays cxd4 first, white has a backwards d4 pawn which is weak. also if white sacs the d4 pawn e5 is weak anyways so it doesnt matter. if white keeps the pawn, the bd3 is void

5.Qxd4 is a mistake, Bxd7+ is correct, then you are up a whole queen for a pawn

That's the trap

Chesster, it may look like black is well developed and has good pressure on the d4 square and e5 pawn, but the specifics of the position go against him. White is poised to play b2-b4 followed by Be3, taking control of the dark squares. Black's kings knight is also finding it hard to develop, while white can expand on the queenside followed by Na3-c2 at his leisure. It is extremely difficult to play black in this kind of position.

You can tell that to Nimzowitz- although I think he won't reply.

According to him the ideal setup for white in the Advance French is with an exchange at c5, a bishop on d3 (optimally protected from exchange via a2-a3, but c2-c3 also goes) and then orchestrating a kingside assault. The "weak" e5 pawn can be (over)protected in various ways.

Himself provocated some times this setup by 4.Qg4, which is somewhat flawed tactically (but it's not really a bad move).

yeah, but the line that you told gave black a BISHOP and pawn for a queen. In the line that I told, White is up a queen for a pawn. Of course, both are Winning, But my line is easier to win

Both work, you'll probably win either way

1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.Bd3 cxd4 7.cxd4 Bd7 8.O-O Nxd4 9.Nxd4
    ( 9.Nbd2!? Nc6 )
9...Qxd4 10.Nc3 a6 ( Black has to remember not to take the second pawn, he must be some kind of genius )

But the line that I said is easier to win lol

The trap is suppose to go the way Aalv has mentioned.

Which is below:

This is the correct way of doing the trap.

You win the 1 queen in exchange for 1 pawn + you make black unable to castle any more!

Which allows you to attack the black king alot more to win more material.

In the Milner Barry Gambit black does have another trap.

I personally don't feel like talking about it.

However, if you want to see the other trap.

You can go to the below thread:

A few days ago a person was playing against this line.

I went through the moves which can help you understand.

You will see the other trap and you will see were the OP messed up in the other forum.
