Kibitzer's Corner
Aug-13-04  RonB52734: This is today's "opening of the day," and it's one that I've been looking at a bit recently. It doesn't seem to be played anymore at the very highest levels. Is there a reason?
Premium Chessgames Member
  Zenchess: Probably because the English Attack is so popular at the highest levels. That's proably why the Bg5 Najdorf isn't seen as much at the 2600+ level either.

White has scored well with this line lately; he has won or drawn all of this year's games in this database.

Jul-03-05  babakova: I like this setup and regularly play it with both colors getting good results.

  WannaBe: <DrDum> has caused me many head-scratching games with this when we're sparring down at the pub.

(I need to find a solution. And I will continue to explore this line. I also need to explore the Moroczy line.)

Jun-01-06  blingice: <RonB> I'll respond to your very outdated post. I think the reason is two different things: first, if you look at the winning percentages, white is disadvantaged. Since you are likely wondering what causes this disadvantage, the answer seems simple: look at the minor pieces: the white bishop can go nowhere near the center, and it is trapped in front of it's own pieces. It's only escape is to get it to a2 after moving a3. Obviously the bishop placement isn't good. Continuing with the minor pieces, both knights have no opportunities to move towards or through the center. They must take a long trip through their own base to even move their attack to the kingside (which is where black will likely castle). That all is a guess, so I hope it's logical.
Jun-19-06  Stevens: I was just looking at this opening and wondered if there was a "refutation" against black continuing with ...b4 and then ...Nxe4 after the white knight has moved. I don't like the positions (as white) that result from losing the e pawn. Does anyone else here play this line, and if so do they play an anti ...b4 line like maybe 8.Qf3 or do they just take the risk and play the position if black does proceed with the ...b4/...Nxe4 route?
Jun-19-06  RookFile: My memory of researching this is: white plays 8. 0-0, and if black goes for 8....b4 9. Na4 Nxe4 white replies 10. Re1 and was winning the majority of games played. I'll see if I can re-aquaint myself with these lines.
Jun-19-06  RookFile: I think that this lost popularity when Kasparov had some success with a plan involving ....Nbd7 and ....Nc5. Interestingly, this plan was also tried against Fischer, and Fischer won. So: the chess world missed out on some interesting struggles involving this idea.
Jun-19-06  Landman: An early game with black grabbing the e-pawn was Fischer vs Tal, 1959

The later game Fischer-Bednarsky really put a smackdown on the early Nxe4 idea. Doesn't seem to be in the chessgames database. It's in My 60 Memorable Games as I recall.

Jun-19-06  Stevens: thanks <rookfile> and <landman>. i'll check out the fischer game. i've had a few quick games with an engine playing black and it seems pretty equal. White has to wait quite a while to get the material back.
Jun-19-06  RookFile: I think Landman means this game:

Fischer vs J B Bednarski, 1966

Jun-19-06  Landman: Yes <Rookfile>, that's the one. Bednarski didn't tell me he'd changed the English spelling of his name. ;P
Jun-25-06  ArturoRivera: where can i learn theory about the sozin?, and i want to know if despite the a6 move, white can try to play the vermilovic and not castle short?
Jun-26-06  WMD:
Jun-26-06  TylerD: Zenchess wrote that the sozin is seldom seen "because the English Attack is so popular at the highest levels." What is the English attack?
Grateful for answers.
Jun-26-06  euripides: <tyler> The English attack is a couple of blokes with dodgy metatarsals.
Jun-26-06  Chesschatology: The English Attack involves playing f3, Be3,Be2, Qd2, 0-0-0, and pushing k-side pawns, roughly.

It's basically a Yugoslav set-up against non-dragon sicilians.

Jun-26-06  russep: The english attack does not involve Be2. f3 is the main one. Be2 will transpose the game into one of the 6.Be2 lines. Instead f3 and then g4, and a pawnstorm.

  WannaBe: If you wish to look at English Attack, try Game Collection: Najdorf ,English Attack!! or Game Collection: Najdorf, English Attack or Anand vs Topalov, 2006

Or post your question on the Sicilian, Najdorf (B90) page. Happy studying.

Jan-02-07  AdrianP: Anyone who is thinking about grabbing that e-pawn in the line 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 e6 6 Bc4 a6 7 Bb3 b5 8 O-O b4!? 9. Nxe4?! should know the following game: Wang Yu vs Khurtsidze, 2000 where Black is losing by force after move 15 Bxd5!

10 Re1 d5 11. c4! seems to be quite an efficient way of whipping up a quick attack, although White has plenty of other options.
