Suetin once wrote a book called Typische Fehler (Typical blunders). I don't know, if it is available in English.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Thanks for this.  I played 9...Nef5?!, but my opponent did not reply 10. Ba3.  I had pretty good game until a blunder.  I there a book on how not to blunder?

I have a copy of an article on this subject - don't ask me were I found it. Here it is.

The last month I found a closed sicilian game commented by Gary Lane about the interesting line:

1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.a3!?

I consulted with my chessfriend Marco Bulgarini (correspondence player) if he had any experience using this line and he gave me your last game with  this line and show me any analisys how complement of the Lane's analysis.

Here are the analysis:


Bulgarini,,M (2355) - Cardozo,  ,C (2406) [B23]
WCCC 2002, semifinal N°26 ICCF,grupo 8, 01.09.2002
[Bulgarini]

1.e4 c5 2.Nc3 Nc6 3.f4 g6 4.Nf3 Bg7 5.a3!?  e6
 
6.b4 d5 !?  
(Bulgarini) An almost new theoretical move , maybe my rival don't found a satisfactory move with security for your position. now the question is what is the best move for the white side?

6...cxb4 (Gary Lane: Black accepts the challenge) 7.axb4  
A) 7...Nxb4 GaryLane  
A1) 8.e5 Bulgarini Torres,M A1a) 8...Ne7 9.Nb5 0-0 10.Ba3 Nbd5 (10...Na6=) 11.c4²; A1b) 8...Bf8 9.Ba3 b6 10.Be2 Bb7 11.0-0=;  
A2) 8.Ba3 8...Nc6 (8...Bxc3 Bulgarini Torres,M 9.dxc3) 9.Nb5 Bf8 10.Bd6 Bxd6 11.Nxd6+ Kf8 12.e5 gives White a great position for the cost of a mere pawn.;  

B) 7...Nge7 8.b5 Nd4 9.e5! White adopts the accepted pawn structure in such positions to allow a white knight to come to e4.  
 B1) An improvement is 9...Nxf3+ (GaryLane) when 10.Qxf3 d6 (10...d5 Bulgarini Torres,M 11.Qf2 f6 12.exf6 Bxf6 13.Rxa7 Rxa7 14.Qxa7 Nf5 15.Ba3 Kf7 16.g3 h5 17.Bd3 Re8 18.Kd1 Bd4 19.Bc5 Bxc5 20.Qxc5 Qd6 21.Qxd6 Nxd6 22.Ne2 Bd7 23.Nd4 Kf6 24.c3 Ra8 25.Ke2 g5 26.h4 gxf4 27.gxf4 Rg8 28.Kf3 Nf7 29.Be2 e5 30.fxe5+ Nxe5+ 31.Kf2 Ng4+ 32.Bxg4 Rxg4 33.b6 Ke7 34.Nf3 Rf4 35.Ke3 Re4+ 36.Kf2 Rf4 37.Re1+ Kd6 38.Kg3 Rg4+ 39.Kf2 Bf5 40.Re8 Be4 41.Ne5 Rxh4 42.Kg3 Rh1 43.d4 Rb1 44.c4 dxc4 45.Nxc4+ Kd5 46.Nd2 Rg1+ 47.Kh4 Bh1 48.Rd8+ ) 11.d4 gives White a small advantage.;  
 B2) 9...Nef5?! 10.Ba3 The bishop on a3 stops Black castling giving White good attacking chances. 10...d6? (Wight should prefer 10...Nxf3+ GaryLane 11.Qxf3 d6 12.exd6 with an edge and victory is still a long way off in the distance.) 11.Nxd4 Nxd4 12.Bxd6 Urquhart has won an extra pawn and the attack still rages. 12...Bd7 13.Bc5 Bc8 14.Ne4 As usual a knight on e4 in this line is heading for the d6 square to create despair for Black. 14...Qd5 15.Bd3 b6 16.c4! 1-0 Urquhart,E-Wight,K/Ontario CAN 2002/[GaryLane] (16)]

Does anyone have any ideas or comments about the grand-prix attack/wing-gambit hybrid?  A week ago I ran into 1. e4 c5          2. Nc3 Nc6    3. f4 g6    4. Nf3 Bg7  5. a3 Nge7  6. b4 cxb4....Anyway, is there a refutation to white's play?
