Hi guys,
I also looked at the Davies book.  However, the lines seemed to peter out to endgames a lot.  Do you guys agree?

There has been a little debate on 5...e6 indeed, but I cannot refind it. In my notes I have only 5...e6 6.axb4, but I remember that Sherbakov game. I was not impressed by Black's play (12...Qd4). I will give it another try.
Me checking your notes on 5...e5 will have to wait a bit. A few years ago though I came to the conclusion that White had enough after 5...e5 6.Bb2 Nc6 7.c4.

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.

What is wrong with the moves recommended by Davies. I.e.

1.e4 c5 2.b4 cxb4 3.a3 d5 4.exd5 Qxd5 5.Nf3 e6 6.Bb2 Nf6 7.Bd3 Nc6 8.0-0 Be7 9.Re1 0-0 10.Ne5! Nxe5

if 10...Bd7 then 11.axb4 Nxb4 12.Nc3 Qd4 13.Be4 Qb6 14.Nxd7 Nxd7 15.Bxh7+! etc. Sherbakov,R (2555)-Das,A (2352)/Pune 2004

11.Rxe5 Qd8 and now instead of the once played Rg5 White could consider 12.axb4! Bxb4 13.Rg5 Bd6 [ 13...Be7 14.Rxg7++- ] 14.Qf3 Kh8 15.Ra4 e5 16.Rh4 +=

Did I miss a discussion?

5...e6 and I have failed to prove sufficient compensation.

Main Line - Wing Gambit (B20)

Recently I have been playing the Wing gambit extensively on ICC, following the repertoire of Nigel Davis Gambiteer to spice up my games. A few initial conclusions I would like to share with you.

No 1: The main line is quite playable for White after the reletively new 6. Bb2

Some analysis and games to support this conclusion:

1. e4 c5
2. b4 cxb4
3. a3 d5
4. exd5 Qxd5
5. Nf3 e5
6. Bb2 Nc6
7. c4!


Having come this far Black now tends to pick up the pawn. In another thread I will investigate the positions where Black moves the Queen immediately.

7 ... bxc3
8. Nxc3


The main move now played is

8 ... Qd8

Alternatives are:

  • 8...Qc5 This is the stem game with 7...bc3 and a difficult nut to crack. The Queen will now in due course encounter threats by a White rook on c1. In Trommsdorf / Comp. Fidelity Prestige White immediately played 9. Rc1. White´s strongest move appears to be 9.Qa4! ( 9.d4 exd4 10.Nb5 Qb6 11.Bxd4 Nxd4 12.Qxd4 Qxd4 13.Nfxd4 Rb8 is equal. ; 9.Bb5 Nf6 10.Bxc6+ bxc6 solves Black´s problems ) 9...f6 ( 9...Bd7 10.Nb5 Qb6 11.Bxe5 Rc8 12.Rc1 ² ) 10.Bb5 Bd7 11.d4 exd4 12.Ne4 Qd5 13.0-0 a6 14.Rfe1 0-0-0 15.Bxc6 Bxc6 16.Rac1 Kb8 with compensation for the pawns deficit.
  • The other Black Queen retreat is 8...Qa5!? 9.Bb5! The Bishop pin Bb5 promises White an initative:

    A) 9...Bd6 allows 10.d4! exd4 11.Qxd4 Be7 12.Qd5! ± e.g. Qc7 13.Ne5 ;
    B) 9...a6!? immediately challenges the Bishop, but ends up in a small plus for White after 10.Bxc6+ bxc6 11.Qe2 Bg4 ( 11...f6 12.d4 Be7 13.dxe5 Rb8 14.0-0 fxe5 15.Rfe1 ± ) 12.Qxe5+ Qxe5+ 13.Nxe5 Rb8 14.Na4! Bd7 15.0-0 f6 16.Rfe1! Be7 17.Bd4 += ;
    C) 9...f6 again allows 10.d4 a6 11.Bxc6+ bxc6 12.Qe2 Bg4 (or 12...Be7 13.dxe5 Rb8 14.0-0 += ) 13.0-0 with a small plus. ;

    D) 9...Nf6 10.Nxe5
    D1) 10...Qb6?! 11.Qf3! a6 ( 11...Bd7 12.Nd5+- ) 12.Ba4 ± e.g. Bd7 13.Nxd7 Nxd7 14.0-0 followed by Re1 and Black has serious problems. ;
    D2) 10...Qc7! Black needs to attack the Knight, otherwise White´s Queen gets into the play. 11.Qe2! Be7 ( Black better brings his King into safety as quickly as possibel. E.g. 11...Be6?! 12.Rc1 Be7 13.0-0 0-0 14.Bxc6 bxc6 15.Nb5 Qb7 16.Nxc6 ± with an extra pawn and the initiative with White ) 12.Rc1 0-0 13.Bxc6! (Not 13.Ne4 as Nxe4 14.Qxe4 Bd6! solves all Black problems. ) 13...bxc6 14.Nb5 Qb6 15.Rxc6 Qb7 16.0-0 += and White is a pawn up, although Black has some compensation due to the bishop pair in the open position. ]

Back to the main line with 8..Qd8.

9. Bb5!

9.Bc4 has been played as well, but the text move is more thematic and promises at least a +=.
9 ... Bd6
10.d4!
+=

Theory and practice concentrate on 10. Ne4. In my view the text is better. 10.Ne4 Nge7! (The two alternatives indeed land black in bad weather. 10...Nf6?! 11.Nxd6+ Qxd6 12.Bxe5 Qd5 13.Qe2 += 0-0 14.Bxf6 Bg4 15.Bxc6 bxc6 16.Be7 Rfe8 17.0-0+- 1-0 Kravtsiv,M (2417)-Blomqvist,E (2133)/ Herceg Novi 2006 (41) ; 10...Bc7? 11.Nxe5 Qd5 12.Qe2+- Bxe5 13.Bxc6+ Qxc6 14.Bxe5 with dreadful threats, although ½-½ Hrabinska,M (2294)-Benmesbah,N (2179)/ Guingamp 2007 (52) ) 11.d4 ( 11.Nxd6+ Qxd6 12.Bxe5 Qg6 13.0-0 0-0= again with a dead equal position,Hrabinska, M (2250)-Koziak,V (2462)/Alushta 2006 (40) ) 11...Bc7 12.dxe5 0-0 13.0-0 Bg4= and Black has solved all his problems.

10...exd4

10...e4? just drops a pawn 11.Nxe4 ± Qe7? 12.0-0 Kf8 13.Nxd6 Qxd6 14.a4 Nge7 15.Ba3 Qc7 16.d5+- was one of my ICC games.

11.Qxd4

White's development advantage is huge. 11..Nf6 [or 11...Nge7 12.Rd1 Nf5 only move 13.Qe4+ Kf8 14.0-0 with initiative] 12.0-0-0! moves the game into an endgame with still a good plus for White. Be7 13.Qxd8+ Bxd8 14.Rhe1+ Be7 [ 14...Be6 15.Nd4 0-0 16.Nxe6 fxe6 17.Rxe6 += ] 15.Ne5 Kf8 [ 15...Bd7? 16.Nxd7 Nxd7 17.Nd5+- ] 16.Bxc6 bxc6 17.Nxc6 Be6 18.a4! Rc8 19.Nxe7 Kxe7 20.Ba3+ Ke8 21.Kb2 ± and Black still struggles to untangle his position.
