Cons of playing the Sicilian Dragon
Have you ever played the Sicilian and encountered someone playing the Dragon? Well let me just tell you there's a very easy way to destroy this opening.
As you can see in this game, White is able to completely annihilate black when black plays the dragon. The main reason white is able to do this is because when Black fianchettoes his bishop, there is a weakness that you can exploit. By aggressively castling queenside, White is ready to storm up Black's castle and crush him to splinters. White's goals in countering the dragon is to queen side castle, line up the queen and bishop for and attack, and push the kingside pawns up the board towards black's castle. Now, you will be fully prepared to play against the Sicilian Dragon so good luck.
