Plans for black when White castles short in the Sicilian dragon What are the plans for Black when White castles short in the Sicilian dragon? Very broadly speaking I am thinking of two plans.


Go for a King's Indian like kingside attack with e5 played at a suitable time.
Do a6-b5 and generate queenside pressure.


Is one more sound than the other? Or is it just a question of style? What should I be aware of before deciding which one to adopt?
Pretty much any open Sicilian when both sides have castled King-side Black can seek counter-play against the center by undermining the Knight on c3 with b5-b4 ideas or if allowed Rxc3 exchange sacs. 

Also thematic is trying to play d5.   Bent Larsen said something to the effect that the Sicilian was a positional trick where you trade a wing-pawn for a center pawn, then with 2 center pawns vs one you will be able to eventually take over the center.

I haven't seen games where Black has prospects of a king-side attack in a Dragon where White castled King-side.  Usually White is trying to attack there with f2-f4 etc.
