To be honest...on your level nearly every opening is sound.
On lower club level you can play any unsound opening, mostly it works, when you are familiar to the main lines, the middlegame ideas and the traps, cause your opponents will rarely know the best defences...
I rarely saw games on this level, which were decided by a pawn more or less :D
So if you wanna play very aggressive try the Latvian Gambit, the sidelines of the Englund and the Blackmar-Diemer.
It will also improve your tactical skills...
I’ve been playing the same openings when possible (Ruy Lopez and Sicilian Dragon as white). I enjoy playing very aggressive openings. Can anybody recommend an aggressive opening that is sound?
