Default B45/3 Sicilian

I played a game this past weekend against an Expert where I got into an
e6/Nc6 setup as Black. I don't normally play that, but it felt rather
comfortable so I've been doing some more research this week.

One of the most challenging responses to the line I'm interested in seems to
be 1. e4 c5 2. Nf3 Nc6 3. d4 cd 4. Nxd4 Nf6 5. Nc3 e6 6. g3.

The B45/3 line in ECO then goes 6 .. d5 7. exd5 Nxd5 8. Bg2 Bb4 9. O-O Nxc3
10. Nxc6 bc 11 bc Bxc3 12. Ba3 Ba1 13. Bxc6+ Bd7 14. Bxa8 Qxa8 15. Qxa1 f6
with equality.

This line and a lot of the sidelines didn't feel particularly comfortable.
I decided to search Chessbase.com to see what the results have looked like
and I ran across a game that went 12. Bxc6+ Bd7 13. Qf1 and White just won
the a-pawn after .. Bxc6 14. Qxc6+ Qd7 15. Qxa8 Qd8 16. Qxa7.

Is this one of those lines that belongs in those ECO Busted books? Where's
a good place to look for an improvement for Black?

Besides the typo Qf1 (Qf3) there must be something wrong here
because 16. Qxd8 wins a rook. Black´s only move after 13. Qf3 is
14...Bxa1 when White can play 15. Bxd7+ Kxd7 16. Rd1+ Ke8 17. Qc6+
Kf8 (17...Ke7 18. Ba3+ Kf6 19. Qf3+ Kg6 20. Rxd8 Raxd8 21. Be7 Rd5
22. Qe4+ Kh6 23. c4 gives Black severe trouble) 18. Qc5+ winning
the pawn a7. White has a good endgame.

Also interesting is 13. Bg5 f6 (13...Bxc6 14. Bxd8 Rxd8 15. Qe2 Bxa1
16. Rxa1 should be winning for White) 14. Qh5+ g6 (14...Kf8 15. Rad1)
15. Qe2 Qe7 (15...Kf7 16. Rad1 Bxc6 17. Rxd8 Rhxd8 18. Qc4) 15. Bxa8
Bxa1 16. Rxa1 fxg5 17. Qe3. White is clearly better.

I think Black has to go back to the 8th move. 8...Nxc3 9. bxc3. Now
Black probably best avoids the hit on c6, for example 9...Nxd4
10. Qxd4 (10. cxd4 Bb4+) 10...Be7. White has pressure against b7 but
Black can counterpressure against c3 (Qa5 and Bf6). Black may also
aim for e5, giving the Ra8 a safe place on b8 and can then untangle
his queenside (b6, Bb7 or Ba6).

Looking in an online database I found Black successfully tried
8...Ndb4. The idea is 9. Nxc6 Qxd1+ 10. Nxd1 bxc6 and the knight
returns to d5.

Both 8th moves have a much better track record than 8...Bb4.

Hello,

I played once the line of Claus-Jürgen:

1. e4 c5 2. Nf3 Nc6 3. d4 cd 4. Nxd4 Nf6 5. Nc3 e6 6. g3 d5
7. exd5 Nxd5 8. Bg2 Bb4 9. O-O Nxc3 10. Nxc6 bc 11 bc Bxc3
12.Bxc6! Bd7 13.Qf3 Bxa1 14. Bxd7+ Qxd7? (better is Claus line with
14...Kxd7!!) 15.Qa8 Qd8 16.Qb7 and I obtained clear advantage in
Torrecillas-Fernandez Spain-ch 1995

After 12.Ba3 Bxa1! black has less problems, if I remember well was
tested in the same Spain-ch by the same player Fernandez and obtained
draw in De la Riva-Fernandez. I'm sorry but I have not this last game
because it was not published.

Thanks for the help!

It was late last night and apparently I got confused typing in some of the
lines I'd been trying out and combined several. Like you guessed I meant
Qf3.

I like 8 .. Nxc3 best out of the choices so far.
