Sicilian Defence Dragon 9.Bc4

The sharp Sicilian Defence Dragon Variation gives stronger players a big advantage. Better players to take advantage of tactical mistakes by their opponents. Tactics rule in chess play. Good chess moves must be safe and active. Higher rated players excel in combinations and checkmates when compared to their lower rated counterparts.

Dave Dieffenbach boldly played sharp openings, but this gave him many opportunities to go wrong. In 1996, David was rated in 1252. I was rated 2010. Black choose moves that were active but not safe. Black's 12...Ba6?! and 13...b5? allowed White the strong post 15.Nd5 with serious threats. White reached an endgame up a rook and two pawns for Black's light squared bishop.
