Default Sicilian 4 Ns Discoveries

Greetings. You might remember "Sicilian 4Ns 6. Bg5" which I
posted on 14feb2004 and 6mar2004; I've been sort of looking
at the Sicilian 4 Ns on and off ever since ...

After 1. e4 c5 2. Nf3 e6 3. d4 cd4 4. Nxd4 Nf6 5. Nc3 Nc6 6. Bg5
I wrote:

Or, following Nunn and Gallagher's hint about the free f8-b4 diagonal:
d. 6... Bb4!?
e. 6... h6 7. Bh4 Bb4!?
A. 8. Ndb5? g5 9. Bg3 Nxe4 10. Nc7+ Kf1 11. Nxa8 Nxc3 12. bc3
Bxc3+ 13. Ke2 Nd4+ 14. Kd3 Qa5 15. Rb1 (15. Be2 Bb2!)
15... b5 idea b4, Ba6+ (Pachman)
B. 8. Nxc6! bc6
a. 9. Qd3
b. 9. Qd4 c5 10. Qd3 Bxc3 11. Qxc3?! Nxe4 12. Qxg7
Qxh4 13. Qh8+ Ke7 14. g3 Nxg3 15. fg3 Qe4+ 16. Kf2
Bb7 17. Qxh6 Qf3+ 18. Ke1 Qe4+ draw


I had great fun analysing Pachman's old king chase (also 14. Ke3 Bxa1
15. Kd3 d6! is interesting) before realizing that 12. Qd3! Ne4+
13. c3 refutes it :-(

I tried to rescue 7... Bb4 with 8. Ndb5!? O-O which more or less
works, but then found that 8. Nxc6! bc6 9. Qf3! favours White.
So for Black I'm now back to 6... h6 7. Bh4 Be7, agreeing with
Wade, Speelman, Povah and Blackstock, and also with Polugaevsky
in his "Sizilianisch, Morra-Gambit bis Scheveninger System",
Sportverlag Berlin 1986.

The other discovery is in the 6. Nxc6 bc6 7. e5 Nd5 line, after
the less usual 8. Nxd5 cd5 9. Bd3 Qc7, White has a scary gambit
which I'd never heard about; 10. O-O! Qxe5 11. Re1 Qf6 12. Re3!
(12. c3 Bc5 13. Be3 Bxe3 14. Rxe3 O-O is not so strong) and
White's Bs, Q, R are a Dream Team.

Black has a couple of 9th-move alternatives:
9... d6 10. Bf4 Qc7 11. Qe2 Bd7 12. O-O de5 13. Bxe5 Bd6 14. Bxg7
Rg8 15. Bf6 Bxh2+ became famous after Showalter - Mieses 1900,
but unfortunately 15. Bc3! wins for White.
9... Ba6 10. O-O Bxd3 11. Qxd3 Qc7 = is suggested by Polugaevsky.

Any other recent gossip in this 8. Nxd5 line ?

Regards, Peter Billam
