It's not a bad line, although the novelty value of this idea has long gone.

6..e5 7 nf3 nbd7 is meant to be a pretty solid equaliser - 8 bc4 isn't that great but 8 bd3 can be tricky although the ef bb4 bg4 seems to neutralise white's chances and if he knows his stuff the qb6 lines grabbing the pawn black may be ok. 8 g4 !? crazy move by Volotkin .

I'd suggest look at the Sharpest sicilian for the details.

Alternatively 6.. nbd7 /qc7 should be ok as well.

6..e6 is a pretty sound move but of course both sides need to know the intricacies of the Schevenginegn.
