   12. 0-0-0 is another try. However as much as White tries, he couldn't get Black's d pawn as Leslie's tactics frustrates him.

   A exciting Kingside vs Queenside pawn storm results from Leslie's unorthodox double fianchetto opening.

   Despite White's two bishops and protected passed pawn, his minor pieces are hitting air whereas Black's exert pressure on the centre.

   Normally, the open White d-file for White vs the open Black f file structure is considered better for White. However, the play's the thing!
