Black can't easily force a King's Indian against the KIA, because after 1.Nf3 d5 2.g3 c5 3.Bg2 Nc6 White has 4.d4! with an improved Grunfeld, or else a transposition to a Catalan with 4...e6 5.0-0 Nf6 6.c4.
His best move order is probably 1.Nf3 Nf6 2.g3 c5 3.Bg2 Nc6 4.0-0 e5 for that purpose, but White has plenty of alternatives (5.e4, or an early c4)
You are true. But against 1.Nf3 Nf6 I play 2.c4. And against 1.Nf3 c5 I play 2.c4. So the only concern is 1...d5 and 2...c5 by Black.
I am experimenting with 1.Nf3 d5 2.e3 (I have both Cummings and Smith e3 books) and I think the most challenging line for White is the Tarrasch (the non-g3 Tarrasch).
1.Nf3 d5 2.e3 Nf6 3.c4 is OK for me (QGA with no d4, or some e3-English, or Cummings-anti-QGD...)
1.Nf3 d5 2.e3 c5 (not sure how often I would face this) 3.c4 d4 4.b4 is ok for me (reversed Blumenfeld)
1.Nf3 d5 2.e3 e6 3.c4 c5 is forcing myself to play d4 (or Black would play it) and now I have the Timid-Tarrasch XD
Any thoughts how to play in the third option (or maybe there is scope to play for a win in this structures as Smith points out with his a3) ?
The 1.Nf3 d5 2.b3 seems interesting. What type of play are you aiming for, guys? Where could I find some material on this? Or what games are interesting to check? It seems to me that a Zukertort would appear yes or yes in the board...
Thx !
