The line youre referrimg to is with the moves a4 and b6 included I believe. However, Im talking about a direct f4+e5 assault. But as I said even this line looks ok for Black but I much prefer White as Black has to really play precisely in order to survive the onslaught.


You are totally right. The moves a4 and b6 are included in SB Hansens main variation. I actually started a thread on both these variations, but nobody answered. Anyway, I agree that Black has to play precisely in the f4+e5 line and that Black's position looks a bit suspicious.


I am now a bit confused. You recommended the lines from Experts vs the Sicilian. This is by SB Hansen, with 5.Nc3. Following 5 ...Qc7 6.Bd3 Nf6 7.0-0 Bc5 8.Nb3 Be7 9. f4 d6, the recommendation is 10. a4!

The variation you talk about, I guess with 10. e5, is given here at Chesspub in the game Nepomniachtchi-Karttunen, I think in the November 2010 update.

I quite like the less common 5.c4 for White, when 5...Nf6 6.Nc3 Qc7 7.a3 should favour White, but 6...Bb4 7.Bd3 Nc6 appears to be more critical.


Do you have the old De la Villa's book? (The Spanish edition: Desmontanto la Siciliana) He promotes 8.Bc2 there. He doesn't explain the reason why he chose 5.Nc3 in his NIC edition of the book.

TN, I've studied that variotion (5. c4 Nf6 6. Nc3 Qc7 7. a3!?) in some deepth but i'm not sure about white's best developmente against an hedgehog (b6 - Nbd7 - Bb7...). Do you like g3 - Bg2 or Be2 ? Do you like f3 or f4 ?

Thanks,
Alessandro


I tend to play Be3/Be2/0-0/f3/Qd2/Rfd1/Rac1/b4/Nb3/Kh1/Bf1 in some order. Sergei Kasparov had a very good survey on this pawn structure in Yearbook 95 (I checked this time!).

7.Qe2 is a very interesting try as well, covered in the Forum section of Yearbook 98, but it's only equal after 7...Nc6 8.Nc6 dc6. Maybe White can play 8.Nf3 but I don't believe in it.

First of all, Id recommend 5.Nc3 over 5.Bd3 and follow the recommendation given in Experts vs The Sicilian. As far as I know Black has still to find a fully satisfactory solution to this line. Hellsten's recommendation to this line looks objectively OK, but I still wouldnt wanna sit with the Black pieces.


I think that SB Hansen has provdided some interesting lines, but it seems as he has missed some critical responses for Black in the lines where White plays Qf3-Qxa8. However, I agree that against any unprepared Black player, the lines recommended give good play for White, and it is telling that he himself says he stopped playing this particular variation due to this.

However, if you wanna stick with 5.Bd3 then Ive found that 8...d6 9.0-0 Nd7 10.Na3 can be a bit annoying, but if Black plays according to The Rybka 3 Opening Book, with 10...Ne5 11.Nc4 Nxc4 12.Bxc4 Bd7!then Black looks to be pretty okay imo.

Against Main Line Kan

What line do you recommend against the "main line kan" 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 a6 5. Bd3 Bc5 6. Nb3 Be7 7. Qg4 g6 8. Qe2 (this is Hellsten's main line)?

I suspect that positional ideas (without c4, with a4 - Nd2 - Nc4) are too slow and sooner or later balck pushes d5 and at least equalizes.

On the other hand, lines with c4 and maybe f4 (or f3) are strongly discouraged by the Nb3 because I can't play b3 (and sometimes Bb2-Ba3) as in the "classical lines" with 5...Qc7

Thanks,
bye
