My typical O'Kelly Variation, offered at the earliest possible opportunity -- something that gets me in trouble if c4 is played before Nc3 or some other disqualifying move.
3. a4
Slowing the eventual queenside expansion. I have no real argument against that.
3... e6 4. g3
I'm can't recall ever losing with the pawn structure of the O'Kelly Sicilian vs the pawn structure of a KIA derivative, but I acknowledge that pressure on the long light-squared diagonal could be quite an asset.
4... Bf8e7
My development is almost mechanical.
5. Bf1g2 Nb8c6 6. Ng1e2 d6
I'd like to play d5 but, g2 bishop and the lack of an f3 knight make that impossible.
7. d4 cxd4 8. Ne2xd4 Ng8f6
A nearly typical O'Kelly position (except for the fianchetto).
9. h3
A KIA idea I'm familiar with, from my play with Dr. Frank Greiner of Mobile, AL. Never seen it in this context.
9... O-O 10. Bc1e3 Nc6e5
A silly sort of idea, maybe, but I'm tempting f4, overexposing his kingside (IMHO).
