I prefer 1,c4 and 1.Nf3
survey: are you an 1.e4 person or a 1.d4 person

If i know my opponent 1.d4
If i dont know my opponent 1.d4
If its a 1 day tournament 1.d4
If its a 2 day tournament 1.d4
If its a 3 day tournament 1.d4
If its a tournament in another state 1.d4
If its a game at the club 1.d4
if its for fun 1.d4

1 e4. because it tends to lead to the open game I'm comfortable with.
If my positional understanding gets better, I may go for 1 d4 or even some of the "modern" stuff!

Depends. If I know nothing against my opponent, then E4 (if white)
If I know something about my opponent (rematches, watching them play, etc.) then whatever knowledge I have may or may not lead me to start otherwise.
EDIT: Then again I'm a noob and suck at chess...so don't take my answer too seriously.

e4, and I played g4 for a while, it works for lower rated players, and for those who know to deal with it, it cracks. There should be some graphics, (e4 how many percentage and d4 how many percentage, others how many %). I hope you do that after you get sufficient replies.

you could've summed that up in two characters.
d4
i'm just wondering what first move people prefer. one isn't better than other i'm just wondering what you prefer.
if you play the English, reti, van Geet, bird, Hungarian and Nimzowitch-Larson attack. please let me know also.
personally i'm a d4 person.
