How to handle this Sicilian Dragon line precisely?

The question might not be original, but here it goes:

Ive seen a game similar to that, but a knight was on e7. The game continued Bxh6 Qxh6 Nf5. Probably not what you're looking for, though.

10...Nxd4 should instantly ring a bell. :)

10.Bh6 is not good..  ..the Q is over loaded garding B on h6 and the N on d4

so 10...Nxd4 wins a pawn :Nxd4 BxB forced (Q takes looses a piece obviously) Nxf3

the N sac is very sound .. realy good idea i like it.. and after Nxe4 fxe Bxd4 BxR QxB black is exchange dawn for a pawn and pair of bishops and semi open c file and an isolated pawn for white

Yeah, you're all right! It's just that sometimes I switch to completely abstract thinking, whereas the given position is all about pure tactics, nothing muddy. Thanks!
