I base all of my openings on attacking chances, so I'd suggest most of the openings I play:
WHITE (1.e4) - King's Gambit against 1...e5 and Sicilian Grand Prix Attack against 1...c5 (with 2.Nc3 and 3.f4). Also the Reti Gambit against the French (1...e6 2.b3).
BLACK - The Schliemann Defense against the Ruy Lopez and the Two Knights Defense (Traxler Variation) against the Italian Game. Against d4, I suggest the Albin Counter Gambit or the Semi-Slav if you're not turned off by theory.
Hey, just want some opinions of the best attacking openings for black and white(2 for black, one for e4 and the other for d4). I quite like the urusov gambit but its quite hard to get into so any ideas?
