e4

Nf3 :P a waiting move from the get go - can transpose into almost anything. I've seen players with a that Deer in Headlights look with i open with Nf3.Besides almost every tournament player is well prepared to meet e4. As for d4 that's about equally good as Nf3 i think.

d4 slows down the hotrods :)

I would use e4 even though the sicillian defence plays strongly tords the center and promotion od the pawn on d4. But if faced with the sicillian I would play the Smith Morray. Its 1. e4 c5 2. d4 pxd4 3. c3 pxc3 4. nxc3. The advantage is that you have a pawn on e4 and a knight on c3 versus there no development and lost c pawn. The only problem is that your down a pawn. But e4 works good for me.

e4 gives you equality

I use both... 1.e4 I use for openings like Ruy Lopez, Kings Indian Attack, and 1.d4 for the Queens Gambit. 1.d4 provides more lasting pressure in the middle and has less chance of tactical surprizes.... 1.e4 is more for open games, rather than slow manuvering... For me both work equally well..

d4

@Steliyan_Petkov_Georgiev I do not agree that if you want to win you should play e4 and if you want a draw - d4. In general if you play the white you should always look for the win no matter of the opening move. Chess theory is very profound so you should play the debut you know best. If you feel more comfortable with e4 it is stupid to play d4 just because you think you get a better chance for a draw.
