Exactly.
Your Favorite Opening?

I've been playing Queen's gambit for several months. Had good opening success because I knew intentions behind each move but had really bad losses in middle game mess-ups and end-games too.
As black I go with KID or similar looking positions [ I do not know the names].

I find it funny that the OP's favorite opening as Black against e4 is the "Sicilian Dragon" and he doesn't even know what the Sicilian Dragon is!
Dragon: 1.e4 c5 2.Nf3 d6 (NOT Nc6) 3.d4 cxd4 4.Nxd4 Nf6 (something must be done about the e-pawn for White) 5.Nc3 g6 6.Be3 Bg7
Accelerated Dragon: 1.e4 c5 2.Nf3 Nc6 (As the OP mentioned) 3.d4 cxd4 4.Nxd4 g6 (No pressure on e4, therefore 5.Nc3 is not forced, and 5.c4 also becomes an option for White, and is exactly what I would play - known as the Maroczy Bind!) 5.c4! (5.Nc3 Bg7 leads to OP's post on his Black game)
my favourite opening is the sicilian defense. I play it with both colours from age 7.
