Dragon: Exploiting White's early pawn pushes

In my next game a Dragon, I was determined to improve on a poor club game I had played with the Dragon where I hadn't castled and ended up losing. Over the last year I have learnt some interesting techniques when playing the Dragon as Black - two of which stand out in this game - one is exploiting tactics against early pushes for White on the King side. The second is sacrificing a pawn on b5 with a view to regaining it with attacks on the b2 pawn (the threat is seen below)! This was my first win in the tournament ...
