I like the Queens and king's because they attack ,defend and gain position of the middle at the same time.     

were you referring to gambits

i like to start with knights

I like two advance one of my central pawns two squares forward. My favorite first move is d4, and my favorite opening is the queens gambit.

i always use king pawn.

i'm quite an admirer of bobby fischers, who never used queen pawn on principle.

as for knight openings, they seem too passive to me.

like Kasparov and his gruenbergs defence and I also like starting by moving the queens pawn forward.  

Is "gruenbergs" correct?  

I like e4

I was refering to that.

I like to play 1.e4 and sicilian or king's indian with Black.

Markus99, I think you want to say "Grunfeld defense", one of the most preferred Kasparov's openings (with King's Indian).
