With d3, you get an additional KIA option against the e6 Sicilian as oppossed to the long KIA line in the French which involves Qe2 and holding back on the b1 Knight so it can go to c3, and also play c4 to punch Black's queenside counter play on the nose. Otherwise, you can just play it like a KIA vs French.
With g3, you are holding the option to go d4 in one go. As menioned above, you allow 3. ...d5 and play vs an IQP, which you might like. Also a good set up vs the KIA is c5/e6/Nc6/g6/Nge7, however 3. g3 causes difficulties for Black to get this set up
If you are playing the KIA vs the French, d3 seems more logical, but if not, then either option seems about the same to me, but if going with d3, use Qe2.
N.B. I think in all cases Black should equalise, and French and e6 Sicilian players seem well prepared for the KIA nowadays in my experience.
Thanks JEH (btw, congrats on 10th year on the Forum, I am 3 yrs behind but not as many posts!
) Thanks for the good advice.
The example for Nge7 is good. As explained in reply to katar, I probably won't go for the KIA.
In the Kornev book, the other "mainline" is of course …d5 and in one Var, 5…Nf6, White plays agst IQP,
In 2nd Var, 5…Nc6 6…Bg4, there is a doubled up IQP pawns and an endgame with N vs B. Hmmmm, perhaps a study of Fischer games with Knights? (I think I got that right?);
In 5…Nc6 6…Nf6 Var, Kornev does not advocate classical plan of Knight blockade with Knight manoeuvre Nb1-d2-b3-d4 but instead recommends capturing IQP.
Kornev in his conclusion index mentioned that the …d5 Var results in Tarrasch-like IQP positions but with pawn on c2 not on e2.
The …d5 mainline is mainly in line with my proposed study of French Tarrasch IQPs with Denis Yevseev's book. So I think should not be a problem.
But with other mainline 3…Nc6,
Kornev concludes that centre is closed, play is focused on flanks. White must watch out for "B's counter play connected with f7-f6, b7-b6, a7-a5, Ba6 and b6-b5.
So same question as to katar, any suggestions on studying the resulting positions arising from the "mainline"?
Is this similar to a Qe2 KIA as you recommend and which kylemeister mentioned is a KIA a tempo up? Should I be looking also at KIA Qe2 games as well to study the positions? I am afraid I have forgotten most of my KIA stuff (memory problems!)
BTW, in the position you posted with 4…g6, Kornev addressed this and gives Internet game Starosek vs Pugachov 2004. Kornev concludes a 11.0-0+/= as B does not have compensation for pawn.
Interestingly the Starosek-Pugachov game proceeds to a Q-less middle game with a White's Q-side pawn majority. And of course this reminded me of Evgeny Sveshnikov's c3 Sicilian book where he has an entire chapter on this Q-less W's Q-side pawn majority structure. Hmmmm, I might just have answered partially my own question i.e. if B plays 4…g6.
But if 4…Nf6???
Thanks again, JEH and kylemeister.
