Man, the Poisoned Pawn Is Hard to Play

What does Black do after 8. a3?
He plays a normal developing move, like 8...Nbd7, or 8...Nc7, or even 8...Be7.

White is usually at a disadvantage in real terms in the sharp Sicilian variations. I play my very own Sicilian which below master strength scores well. Dave Tebb beat me in it but he played very well and as a result I altered my play as black from then on, A rather famous GM beat me but I had a winning position. He showed me later.
Thanks!
