Kibitzer's Corner
Aug-11-04  InspiredByMorphy: This should make game of the day sometime. White is almost 500 points lower rated and delivers a smacking!

  Zenchess: Well, that's what Black gets for playing such a poor move as 6...Bb4?. Some moves like this are not book for a reason. Black can't get castled and gets swamped by White's mating attack.
Aug-11-04  marcus13: Zenchess, I think you mean 5. ... Bb4. In fact this opening is dubious, but book it is call the Sicilian Counter Attack.
Premium Chessgames Member
  Zenchess: I don't think it's safe to play such dubious lines anymore. 10-12 years ago, I played the BDG regularly and beat stronger players with it sometimes. Even experts had trouble against it. Now, 1200's can beat me when I try this opening. And I win with Black against it all the time.

The thing is, if you play dubious openings against people 500 points lower than you, your risk getting your goose cooked.

Aug-12-04  InspiredByMorphy: <Zenchess> <that's what Black gets for playing such a poor move as 5...Bb4?.> I know a master rated 2300 who told me he played it frequently in the past and rarely lost a game with it. The Sicilian counter attack is strong. One reason being is that after 6.e5 Bxc3+ 7.bxc3 Nd4 can be played with safety.
Aug-12-04  InspiredByMorphy: <Zenchess> Look at the following game before making any more judgements about the Sicilian counter attack. Black plays a much more sensible 7th move and wins. R Arlauskas vs L Dreibergs, 1946

  Zenchess: I'm not totally convinced, but I do agree 6...Nd5 or 6...Bxc3 are better than what Black did. Black frequently has to sacrifice the exchange in these lines.

After 6...Nd5 7. Qg4 g6, White can play 8. Ndb5, intending either 8...a6 9. Nd6+! Bxd6 10. exd6 Nxc3 11. Qxd4 or 8...Nc6 9. Bd2 and White avoids the doubled pawns.

If 6...Bxc3 7. bxc3 Nd5, White can play 8. Nb5 O-O 9. Ba3, winning the exchange. Black has some compensation because of his lead in development and White's doubled pawns, but I don't think its enough.

Aug-13-04  InspiredByMorphy: <Zenchess> <6...Nd5 7.Qg4 g6 8.Nbd5> ... Qa5 9.Bd2 Nc6 and if 10.a3 Nxc3 11.Bxc3 Bxc3 12.Nxc3 Qxe5+ winning a pawn. If 10.Nd6+ Ke7 then 11.Qg5+ f6 threatens whites queen and knight on d6 indirectly. <If 6...Bxc3 7. bxc3 Nd5, White can play 8. Nb5 O-O 9. Ba3, winning the exchange.> White wins no such thing. If this is true why did you not provide how it is done? 9. ... Ne7 and I see no threat. 10. Nc7 is no good as after ... Qxc7 11.Bxe7 Qxc3+ looks very bad for white. The king must move or lose a rook.
Aug-13-04  Cyphelium: <Zenchess & IBM> The 5.- Bb4 variation is playable of course, especially at club level where few have had taken the time to learn all the variations. Against stronger opposition, it's certainly risky though. BTW, after 6.- Nd5 the strongest move is probably 7. Bd2, according to Nunn's Chess Openings. In the opening explorer, you can see that white scores almost 70 % (out of 38 games) with it.

  Zenchess: Inspired by Morphy: In your 1st line, 10. Nd6+ leaves White much better. 10...Ke7?? loses to 11. Nxd5 Qxd5 12. Qg5+ Kf8 13. Bxb4 and the B cannot be captured because of mate in 4.

In your second line, White can play 10. Bxe7? first, deflecting the Q from the defense of c7. However, after 11. Nc7 Qc5, White wins the exchange, but Black has overwhelming compensation because White's King is exposed.

So White should prefer 10. Bd6! Na6 11. Bd3 and he is much better because of his stranglehold on d6 and e5.

Aug-13-04  InspiredByMorphy: <Zenchess> <6...Nd5 7.Qg4 g6 8.Nbd5 Qa5 9.Bd2 Nc6 10.Nd6+ Ke7 loses to 11.Nxd5 Qxd5 12.Qg5+> Did you bother to look at move 11 in this line where I said If 10.Nd6+ Ke7 then 11.Qg5+ f6 . Why would I play 11. ... Kf8? <If 6...Bxc3 7. bxc3 Nd5, White can play 8. Nb5 O-O 9. Ba3 Ne7 10.Bd6> ... Nc6 11.Bd3 Qa5 threatens 12. ... Qxc3+ dangerously exposing the king, or facing loss of a rook. With this move black also threatens to win a piece with 12. ... a6

  Zenchess: Line #1: You completely missed the point of my 11th move Nxd5 (to remove the Nd5 from the defense of f6). After 11...Qxd5 12. Qg5+ f6??, 13. Qxf6 is mate.

Line #2: 10...Nc6?? loses to 11. Bc7 and 12. Nd6, trapping the queen.

May-02-07  jyske: Guys

There is no known refutation of 5 ...Bb4 it is fully playable. See Zsoyds corresponence games in chessworld won 5 drew 2 I think. See also Aagard (IM) 20 pages of analysis concluding there was no sure way for white to get an advantage. My problem with it is that in the line 6 e5 Nd5 7 Bd2 (best) Nxc3 8 bxc3 Be7 (6 ..Ba5 is also fine but there is a virtually forced draw line) white players dont often grab the exchange anymore with 9 Qg4 0-0 10 Bh6 g6 11 Bxf8 when the comps think white is great only to flip assessment when black gets his bits out. Instead in the best line for white black has just a move only path to hold the game. Of course against 7 Qg4 black plays 0-0 not g6?

May-05-15  Bycotron: 10.Nb3! and black looks totally busted.

Very interesting analysis of the opening by Zenchess, thank you for posting those.
