Extra Module - Opening preparation

Looking at the "Closed Sicilian-into" B23

As quoted below:

"About the pawns: with the bishop fianchettoed, it would be wrong for Black to advance the e-pawn on e5. Beside blocking the bishop, it would leave a "hole" on d5. The black d-pawn aims for d5, even if usually, Black prepares this advance playing first: e7-e6 and d7-d6."

What hold on d5? I can't see a hole? Can someone explain this one and please... keep it simple.

Doesn't it just mean that with pawns on d6 and e5, d5 is a hole in black's pawn structure that white can exploit? That is, it gives up control of the key central square d5.

sometime this course really messes me up.

"it would be wrong for Black to advance the e-pawn on e5."

I think they might mean "to e5" not "on e5"

Yes, there are quite a few slip ups in the content.

BDK, i think your right... AGAIN! The error's in this course really make it hard to follow sometime. But over all i still like the course and i do find it a benefit to my game.

I just reviewed the Queens Gambit Accepted [D27] There was a great example of Kasparov's relentless attacking ability. I am really enjoying this module.

15.c4 Bd7 Black has a hard task to defend his position, like we can see in the following 2 games: [15...e5 16.Qg3 Be6 17.Bh6 Bf6 18.Re1 Rfd8 19.dxe5 Kf8 20.f4 Qb6+ 21.c5 Qxc5+ 22.Kh1 1-0 Aleksandrov,A (2606)-Nikitin,A (2400)/Smolensk 2000/CBM 077; 15...Bd6 16.c5 Be7 17.Bf4 Qd7 18.Rac1 Qc6 19.d5 exd5 20.Bxd5 Qg6 21.h3 Ra7 22.Qe3 Bf6 23.c6 bxc6 24.Be4 Bf5 25.Bxf5 Qxf5 26.g4 1-0 Kasparov,G (2820)-Spangenberg,H (2565)/Buenos Aires 1997/EXT 98] We present 2 more games up to end as they are good examples of how White attacks in this position.

i found the whole game. The interesting thing is Kasparov lost his next game against Hugo, playing the Najdorf of all openings. That was Kasparov's opening!

Wow, black seemed to play really badly (for his rating) in that game. Mind you I am probably missing something. Just seemed to me that black threw away tempos on move 15 and then on move 17.

Very good analysis!

I ran the game analysis on my desktop while my playing against fritz on the laptop and getting pounded once again with the d4 repertoire.

Thought you might find the analysis and positional comments intersting to compare with the course materials. Here's what Rybka/Aquarium has to say.....

When relieving the pawn tension in the centerimmediately, Black intends to
mount it later bymeans of the c7-c5 advance. Very frequently itleads to the
typical positions with the whiteisolated d4-pawn in the center, which heraldsan interesting strategic battle in themiddlegame.}

This is the key position of the Queen's Gambit Accepted that gives rise to
several systems, among which we shall consider the following ones: 1) 6. ... Nc6 2) 6. ...a6!}
a6 {This is the most flexible and promisingcontinuation for Black in the Queen's
Gambit Accepted. Black wants to expand controlled space on the queenside by
playing b7-b5 and developing the queen's bishop to b7. At that,Black hurries
not with opening up the c1-h6 diagonal for the white queen's bishop,
whiledeploying his queen's knight to an elasticposition on d7.}
7.Bb3 {This continuation has recently becomeextremely popular. When retreating with
thebishop to b3, White 'amortize' the impendingb7-b5 advance preparing to meet it fullyarmed.}

Black keeps to the classical interpretation of the Queen's Gambit Accepted. He
hurries not with the pawn exchange on d4 that would let out the white
