user7174: What are the good strategic and tactical plans for White in this position?

1. e4 e6 2. d3 d5 3. Nd2 c5 4. g3 Nc6 5. Bg2 Nf6 6. Ngf3 Be7 7. O-O O-O 8. Re1 Qc7 9. e5 Nd7 10. Qe2 f5 11. exf6 Nxf6

I wonder what should I do with the Black's c, d, and e pawns. How to prevent them from pushing forward and after preventing them from pushing forward, what should be the next plan for White?

user4543: Is it necessary/good to play 9.e5? The centre gets liquidated quite quickly after that. What about 9.c3 with the typical KIA ideas -
1) e5 (which can now be supported by d4) followed by h4, Nf1-h2-g4
2) a4 preparing Nc4 if c4 ever becomes available eg 9... de 10. de e5 11.a4
3) Qc2
EDIT having checked on 365chess.com 9.c3 is indeed a good alternative but in the diagram position 12.Bh3 is often played as the bishop is better on that diagonal whereas Black is not really threatening ...e5.

user7657: I had studied the KIA for a time in the early'90's, although with mixed results, so I don't claim to be an expert on the subject.  In this position 12.c3 would constrain the Black "d" pawn, but I think I would initially play 12.Bh3 to restrain the more important "e" pawn, which is currently backward on the open file.  Then if 12..., e5; 13.Bxc8 & 14.Nxe5 would win it. Or if Black decided to reinforce it by 12..., Nd8, then 13.Ne5 could occupy the hole and then support this N with subsequent 14. Ndf3 and 15.Bf4 moves.  And since the purpose of the KIA is a kingside attack, you would probably subsequently want to mobilize your kingside pawns once you had this center control.  I hope these suggestions are of some value.
