what is yourfavorite start move

for me e4 is best for defense

Me too, I mostly play and like e4, but I do also like Nf3

Push pawn

My First moove as BLACK is to start my opponent's chess clock and wait. 
For WHITE: (1) e4 Spanish/Italian (2) Nf3 - KIA (3) d4 Queen's Gambit (4) c4 English
~ currenty ~ I like to play in Classical style.

I like D4 tbh

E4

I like to play c4 with White, with black against e4 I usually play the Scandi or the Sicilian...
