1.e4 c5 2.Nf3 e6 3.g3 a6 4.Bg2 b5 5.d4! ought to be promising for White.


Grivas thought that this should be good for White, based largely on the game Rozentalis - Reshetnikov, 2009.  His notes in the Megabase (with some help from the computer) do make it all look rather convincing.

Personally, I've always thought that an early ...a6 kind of encouraged White to adopt a kingside fianchetto.  I mean, how often in the Closed Sicilian does Black play ...a6?  Not very.  The only place where this is really justified by Black, that I can think of, is after 1.e4 c5 2.Nf3 e6 3.Nc3 a6!?, when the knight being on c3 already gives Black possibilities against the e4-pawn with the later ...b5-b4 push.

This can be reached by transposition with a Kan move order by 1. e4 c5 2. Sf3 e6 3. g3 a6 4. Lg2 b5 5. d3 Lb7 6. 0-0 with more or less the same scheme.


True, but in contrast to the 1. e4 c5 2. Sc3 a6 line, White hasn't committed the Queen's Knight yet. That may give him additional possibilities.  For example, he might be able to play for c4 or for c3-d4 in some lines.  He can also play a4, when Black's ..b4 only hits air instead of an Sc3.  I haven't parsed through all these possibilities, but one example is  1.e4 c5 2. Sf3 e6 3.g3 a6 4.Lg2 b5 5.0-0 Lb7 6.Te1 d6 7.d4 cxd4 8.Sxd4 Sf6 9.a4 b4 10.c3 bxc3 11.Sxc3 Sbd7 12.e5 dxe5 (Hansen-Magem Badals, Novi Sad 1990).  White is much better after 13.Lxb7 or even 13.Sxe6.

I think many White players automatically respond to this with a4,  to stop ...b5, at least temporarily.

Btw, I think this line with ...a6 against 1. e4 c5 2. Nc3 is recommended in Fight the anti-Sicilians by Palliser.

This 3. g3 is getting popular, and I was thinking about how a Kan player who is also a Najdorf player can exploit this for an advantage. Even if the Kan player is no Najdorf player, if s/he is willing to enter the Najdorf anti-Closed line. I think first of the 2...a6 Najdorf line where Black attempts a queenside fianchetto:

1. e4 c5 2. Sc3 a6 3. g3 b5 4. Lg2 Lb7 5. d3 e6 6. Sf3 with a set-up like a Hedgehog, follow with ...Dc7/...Sf6/...Le7 and develop the kingside. This can be reached by transposition with a Kan move order by 1. e4 c5 2. Sf3 e6 3. g3 a6 4. Lg2 b5 5. d3 Lb7 6. 0-0 with more or less the same scheme.

If I as a Kan and Najdorf player someone plays this 3. g3, is there anything that I am missing that White can try to avoid going into this 2. Sc3 a6 set-up that Najdorf players use? If not this looks like a relatively smooth transition to the line, if Kan and Taimanow players do not mind this Najdorf anti-Closed Sicilian set-up.
