Here’s a great attacking game in the Closed Sicilian by the Hungarian Grandmaster Istvan Bilek. The attack started with 9.f5! is very typical of this opening though in this case it was followed by a brilliant exchange sacrifice (11.Rxf5). There is one very important tactical point, after 13…f5 14.Bd5+ Kh8 15.Ng5 h6 White has the brilliant 16.Qg6! when 16…hxg5 17.Qh5+ leads to mate.
