I love playing attacking chess so my favourite opening is cicilian dragon for black. Which is your favourite oppening in chess?
e4 - e5. It can turn into so many different openings, so it's not boring like the "setup"-openings where you get almost every piece to the same place in the same order every time.
Queen's gambit,slav, carokann are equally my favourite
My favourite opening is sicilian nadjrof for black and Queens gambit for white
White: Classical ruy lopez, Kings Indian defense (Usually Fianchetto although I gravitate toward the Karpov setup ), Bennoni (Knight tour with 8.e4)
Black: Najdorf, Semi Slav
I like KID for white. In one line you can attack with white
Queen's gambit exchange variation in White. French Defense Tarrasch variation in Black.
Grob Spike Attack, Hamnerschlag. Don't hate me for that.
Nimzo-Larsen for white, Modern defense for Black
King's gambit as white and Sicilian Dragon as black.
Although I don't know the theory for both opening :)
